    "content": "---\nname: feature-flags\ndescription: Use when feature flag tests fail, flags need updating, understanding @gate pragmas, debugging channel-specific test failures, or adding new flags to React.\n---\n\n# React Feature Flags\n\n## Flag Files\n\n| File | Purpose |\n|------|---------|\n| `packages/shared/ReactFeatureFlags.js` | Default flags (canary), `__EXPERIMENTAL__` overrides |\n| `packages/shared/forks/ReactFeatureFlags.www.js` | www channel, `__VARIANT__` overrides |\n| `packages/shared/forks/ReactFeatureFlags.native-fb.js` | React Native, `__VARIANT__` overrides |\n| `packages/shared/forks/ReactFeatureFlags.test-renderer.js` | Test renderer |\n\n## Gating Tests\n\n### `@gate` pragma (test-level)\n\nUse when the feature is completely unavailable without the flag:\n\n```javascript\n// @gate enableViewTransition\nit('supports view transitions', () => {\n  // This test only runs when enableViewTransition is true\n  // and is SKIPPED (not failed) when false\n});\n```\n\n### `gate()` inline (assertion-level)\n\nUse when the feature exists but behavior differs based on flag:\n\n```javascript\nit('renders component', async () => {\n  await act(() => root.render(<App />));\n\n  if (gate(flags => flags.enableNewBehavior)) {\n    expect(container.textContent).toBe('new output');\n  } else {\n    expect(container.textContent).toBe('legacy output');\n  }\n});\n```\n\n## Adding a New Flag\n\n1. Add to `ReactFeatureFlags.js` with default value\n2. Add to each fork file (`*.www.js`, `*.native-fb.js`, etc.)\n3. If it should vary in www/RN, set to `__VARIANT__` in the fork file\n4. Gate tests with `@gate flagName` or inline `gate()`\n\n## Checking Flag States\n\nUse `/flags` to view states across channels. See the `flags` skill for full command options.\n\n## `__VARIANT__` Flags (GKs)\n\nFlags set to `__VARIANT__` simulate gatekeepers - tested twice (true and false):\n\n```bash\n/test www <pattern>              # __VARIANT__ = true\n/test www variant false <pattern> # __VARIANT__ = false\n```\n\n## Debugging Channel-Specific Failures\n\n1. Run `/flags --diff <channel1> <channel2>` to compare values\n2. Check `@gate` conditions - test may be gated to specific channels\n3. Run `/test <channel> <pattern>` to isolate the failure\n4. Verify flag exists in all fork files if newly added\n\n## Common Mistakes\n\n- **Forgetting both variants** - Always test `www` AND `www variant false` for `__VARIANT__` flags\n- **Using @gate for behavior differences** - Use inline `gate()` if both paths should run\n- **Missing fork files** - New flags must be added to ALL fork files, not just the main one\n- **Wrong gate syntax** - It's `gate(flags => flags.name)`, not `gate('name')`\n"

Parse channel from arguments (default: source)\n2. Map to yarn command:\n   - (default) → `yarn test --silent --no-watchman <pattern>`\n   - experimental → `yarn test -r=experimental --silent --no-watchman <pattern>`\n   - stable → `yarn test-stable --silent --no-watchman <pattern>`\n   - classic → `yarn test-classic --silent --no-watchman <pattern>`\n   - www → `yarn test-www --silent --no-watchman <pattern>`\n   - www variant false → `yarn test-www --variant=false --silent --no-watchman <pattern>`\n3. Report test results and any failures\n\nHard Rules:\n1. **Use --silent to see failures** - This limits the test output to only failures.\n2. **Use --no-watchman** - This is a common failure in sandboxing.\n\nCommon Mistakes:\n- **Running without a pattern** - Runs ALL tests, very slow. Always specify a pattern.\n- **Forgetting both www variants** - Test `www` AND `www variant false` for `__VARIANT__` flags.\n- **Test skipped unexpectedly** - Check for `@gate` pragma; see `feature-flags` skill.\n"

    "content": "## 19.2.1 (Dec 3, 2025)\n\n### React Server Components\n\n- Bring React Server Component fixes to Server Actions (@sebmarkbage [#35277](https://github.com/facebook/react/pull/35277))\n\n## 19.2.0 (October 1st, 2025)\n\nBelow is a list of all new features, APIs, and bug fixes.\n\nRead the [React 19.2 release post](https://react.dev/blog/2025/10/01/react-19-2) for more information.\n\n### New React Features\n\n- [`<Activity>`](https://react.dev/reference/react/Activity): A new API to hide and restore the UI and internal state of its children.\n- [`useEffectEvent`](https://react.dev/reference/react/useEffectEvent) is a React Hook that lets you extract non-reactive logic into an [Effect Event](https://react.dev/learn/separating-events-from-effects#declaring-an-effect-event).\n- [`cacheSignal`](https://react.dev/reference/react/cacheSignal) (for RSCs) lets your know when the `cache()` lifetime is over.\n- [React Performance tracks](https://react.dev/reference/dev-tools/react-performance-tracks) appear on the Performance panel’s timeline in your browser developer tools\n\n### New React DOM Features\n\n- Added resume APIs for partial pre-rendering with Web Streams:\n  - [`resume`](https://react.dev/reference/react-dom/server/resume): to resume a prerender to a stream.\n  - [`resumeAndPrerender`](https://react.dev/reference/react-dom/static/resumeAndPrerender): to resume a prerender to HTML.\n- Added resume APIs for partial pre-rendering with Node Streams:\n  - [`resumeToPipeableStream`](https://react.dev/reference/react-dom/server/resumeToPipeableStream): to resume a prerender to a stream.\n  - [`resumeAndPrerenderToNodeStream`](https://react.dev/reference/react-dom/static/resumeAndPrerenderToNodeStream): to resume a prerender to HTML.\n- Updated [`prerender`](https://react.dev/reference/react-dom/static/prerender) APIs to return a `postponed` state that can be passed to the `resume` APIs.\n\n### Notable changes\n\n- React DOM now batches suspense boundary reveals, matching the behavior of client side rendering. This change is especially noticeable when animating the reveal of Suspense boundaries e.g. with the upcoming `<ViewTransition>` Component. React will batch as much reveals as possible before the first paint while trying to hit popular first-contentful paint metrics.\n- Add Node Web Streams (`prerender`, `renderToReadableStream`) to server-side-rendering APIs for Node.js\n- Use underscore instead of `:` IDs generated by useId\n\n### All Changes\n\n#### React\n\n- `<Activity />` was developed over many years, starting before `ClassComponent.setState` (@acdlite @sebmarkbage and many others)\n- Stringify context as \"SomeContext\" instead of \"SomeContext.Provider\" (@kassens [#33507](https://github.com/facebook/react/pull/33507))\n- Include stack of cause of React instrumentation errors with `%o` placeholder (@eps1lon [#34198](https://github.com/facebook/react/pull/34198))\n- Fix infinite `useDeferredValue` loop in popstate event (@acdlite [#32821](https://github.com/facebook/react/pull/32821))\n- Fix a bug when an initial value was passed to `useDeferredValue` (@acdlite [#34376](https://github.com/facebook/react/pull/34376))\n- Fix a crash when submitting forms with Client Actions (@sebmarkbage [#33055](https://github.com/facebook/react/pull/33055))\n- Hide/unhide the content of dehydrated suspense boundaries if they resuspend (@sebmarkbage

([#33680](https://github.com/facebook/react/pull/33680) by @hoxyq)\n\n## 19.1.0 (March 28, 2025)\n\n### Owner Stack\n\nAn Owner Stack is a string representing the components that are directly responsible for rendering a particular component. You can log Owner Stacks when debugging or use Owner Stacks to enhance error overlays or other development tools. Owner Stacks are only available in development builds. Component Stacks in production are unchanged.\n\n* An Owner Stack is a development-only stack trace that helps identify which components are responsible for rendering a particular component. An Owner Stack is distinct from a Component Stacks, which shows the hierarchy of components leading to an error.\n* The [captureOwnerStack API](https://react.dev/reference/react/captureOwnerStack) is only available in development mode and returns a Owner Stack, if available. The API can be used to enhance error overlays or log component relationships when debugging.

Read [React 19 release post](https://react.dev/blog/2024/04/25/react-19) and [React 19 upgrade guide](https://react.dev/blog/2024/04/25/react-19-upgrade-guide) for more information.\n\n> Note: To help make the upgrade to React 19 easier, we’ve published a react@18.3 release that is identical to 18.2 but adds warnings for deprecated APIs and other changes that are needed for React 19. We recommend upgrading to React 18.3.1 first to help identify any issues before upgrading to React 19.\n\n### New Features\n\n#### React\n\n* Actions: `startTransition` can now accept async functions. Functions passed to `startTransition` are called “Actions”. A given Transition can include one or more Actions which update state in the background and update the UI with one commit. In addition to updating state, Actions can now perform side effects including async requests, and the Action will wait for the work to finish before finishing the Transition. This feature allows Transitions to include side effects like `fetch()` in the pending state, and provides support for error handling, and optimistic updates.  \n* `useActionState`: is a new hook to order Actions inside of a Transition with access to the state of the action, and the pending state. It accepts a reducer that can call Actions, and the initial state used for first render. It also accepts an optional string that is used if the action is passed to a form `action` prop to support progressive enhancement in forms.  \n* `useOptimistic`: is a new hook to update state while a Transition is in progress. It returns the state, and a set function that can be called inside a transition to “optimistically” update the state to expected final value immediately while the Transition completes in the background. When the transition finishes, the state is updated to the new value.  \n* `use`: is a new API that allows reading resources in render. In React 19, `use` accepts a promise or Context. If provided a promise, `use` will suspend until a value is resolved. `use` can only be used in render but can be called conditionally.  \n* `ref` as a prop: Refs can now be used as props, removing the need for `forwardRef`.  \n* **Suspense sibling pre-warming**: When a component suspends, React will immediately commit the fallback of the nearest Suspense boundary, without waiting for the entire sibling tree to render. After the fallback commits, React will schedule another render for the suspended siblings to “pre-warm” lazy requests.\n\n#### React DOM Client\n\n* `<form> action` prop: Form Actions allow you to manage forms automatically and integrate with `useFormStatus`. When a `<form> action` succeeds, React will automatically reset the form for uncontrolled components. The form can be reset manually with the new `requestFormReset` API.  \n* `<button> and <input> formAction` prop: Actions can be passed to the `formAction` prop to configure form submission behavior. This allows using different Actions depending on the input.  \n* `useFormStatus`: is a new hook that provides the status of the parent `<form> action`, as if the form was a Context provider. The hook returns the values: `pending`, `data`, `method`, and `action`.  \n* Support for Document Metadata: We’ve added support for rendering document metadata tags in components natively. React will automatically hoist them into the `<head>` section of the document.  \n* Support for Stylesheets: React 19 will ensure stylesheets are inserted into the `<head>` on the client before revealing the content of a Suspense boundary that depends on that stylesheet.  \n* Support for async scripts: Async scripts can be rendered anywhere in the component tree and React will handle ordering and deduplication.  \n* Support for preloading resources: React 19 ships with `preinit`, `preload`, `prefetchDNS`, and `preconnect` APIs to optimize initial page loads by moving discovery of additional resources like fonts out of stylesheet loading. They can also be used to prefetch resources used by an anticipated navigation.\n\n#### React DOM Server\n\n* Added `prerender` and `prerenderToNodeStream` APIs for static site generation. They are designed to work with streaming environments like Node.js Streams and Web Streams. Unlike `renderToString`, they wait for data to load for HTML generation.\n\n#### React Server Components\n\n* RSC features such as directives, server components, and server functions are now stable. This means libraries that ship with Server Components can now target React 19 as a peer dependency with a react-server export condition for use in frameworks that support the Full-stack React Architecture. The underlying APIs used to implement a React Server Components bundler or framework do not follow semver and may break between minors in React 19.x. See [docs](https://19.react.dev/reference/rsc/server-components) for how to support React Server Components.\n\n### Deprecations\n\n* Deprecated: `element.ref` access: React 19 supports ref as a prop, so we’re deprecating `element.ref` in favor of `element.props.ref`. Accessing will result in a warning.  \n* `react-test-renderer`: In React 19, react-test-renderer logs a deprecation warning and has switched to concurrent rendering for web usage. We recommend migrating your tests to  [@testing-library/react](https://testing-library.com/docs/react-testing-library/intro/) or [@testing-library/react-native](https://testing-library.com/docs/react-native-testing-library/intro)\n\n### Breaking Changes\n\nReact 19 brings in a number of breaking changes, including the removals of long-deprecated APIs. We recommend first upgrading to `18.3.1`, where we've added additional deprecation warnings. Check out the [upgrade guide](https://19.react.dev/blog/2024/04/25/react-19-upgrade-guide) for more details and guidance on codemodding.\n\n### React\n\n* New JSX Transform is now required: We introduced [a new JSX transform](https://legacy.reactjs.org/blog/2020/09/22/introducing-the-new-jsx-transform.html) in 2020 to improve bundle size and use JSX without importing React. In React 19, we’re adding additional improvements like using ref as a prop and JSX speed improvements that require the new transform.  \n* Errors in render are not re-thrown: Errors that are not caught by an Error Boundary are now reported to window.reportError. Errors that are caught by an Error Boundary are reported to console.error. We’ve introduced `onUncaughtError` and `onCaughtError` methods to `createRoot` and `hydrateRoot` to customize this error handling.  \n* Removed: `propTypes`: Using `propTypes` will now be silently ignored. If required, we recommend migrating to TypeScript or another type-checking solution.  \n* Removed: `defaultProps` for functions: ES6 default parameters can be used in place. Class components continue to support `defaultProps` since there is no ES6 alternative.  \n* Removed: `contextTypes` and `getChildContext`: Legacy Context for class components has been removed in favor of the `contextType` API.  \n* Removed: string refs: Any usage of string refs need to be migrated to ref callbacks.   \n* Removed: Module pattern factories: A rarely used pattern that can be migrated to regular functions.  \n* Removed: `React.createFactory`: Now that JSX is broadly supported, all `createFactory` usage can be migrated to JSX components.  \n* Removed: `react-test-renderer/shallow`: This has been a re-export of [react-shallow-renderer](https://github.com/enzymejs/react-shallow-renderer) since React 18\\. If needed, you can continue to use the third-party package directly. We recommend using [@testing-library/react](https://testing-library.com/docs/react-testing-library/intro/) or [@testing-library/react-native](https://testing-library.com/docs/react-native-testing-library/intro) instead.\n\n#### React DOM\n\n* Removed: `react-dom/test-utils`: We’ve moved `act` from `react-dom/test-utils` to react. All other utilities have been removed.   \n* Removed: `ReactDOM`.`render`, `ReactDOM`.`hydrate`: These have been removed in favor of the concurrent equivalents: `ReactDOM`.`createRoot` and `ReactDOM.hydrateRoot`.  \n* Removed: `unmountComponentAtNode`: Removed in favor of `root.unmount()`.  \n* Removed: `ReactDOM`.`findDOMNode`: You can replace `ReactDOM`.`findDOMNode` with DOM Refs.\n\n### Notable Changes\n\n#### React\n\n* `<Context>` as a provider: You can now render `<Context>` as a provider instead of `<Context.Provider>`.  \n* Cleanup functions for refs: When the component unmounts, React will call the cleanup function returned from the ref callback.  \n* `useDeferredValue` initial value argument: When provided, `useDeferredValue` will return the initial value for the initial render of a component, then schedule a re-render in the background with the `deferredValue` returned.  \n* Support for Custom Elements: React 19 now passes all tests on [Custom Elements Everywhere](https://custom-elements-everywhere.com/).  \n* StrictMode changes: `useMemo` and `useCallback` will now reuse the memoized results from the first render, during the second render. Additionally, StrictMode will now double-invoke ref callback functions on initial mount.  \n* UMD builds removed: To load React 19 with a script tag, we recommend using an ESM-based CDN such as [esm.sh](http://esm.sh).\n\n#### React DOM\n\n* Diffs for hydration errors: In the case of a mismatch, React 19 logs a single error with a diff of the mismatched content.  \n* Compatibility with third-party scripts and extensions: React will now force a client re-render to fix up any mismatched content caused by elements inserted by third-party JS. \n\n### TypeScript Changes\n\nThe most common changes can be codemodded with `npx types-react-codemod@latest preset-19 ./path-to-your-react-ts-files`.\n\n* Removed deprecated TypeScript types:   \n  * `ReactChild` (replacement: `React.ReactElement | number | string)`  \n  * `ReactFragment` (replacement: `Iterable<React.ReactNode>`)  \n  * `ReactNodeArray` (replacement: `ReadonlyArray<React.ReactNode>`)  \n  * `ReactText` (replacement: `number | string`)  \n  * `VoidFunctionComponent` (replacement: `FunctionComponent`)  \n  * `VFC` (replacement: `FC`)  \n  * Moved to `prop-types`: `Requireable`, `ValidationMap`, `Validator`, `WeakValidationMap`  \n  * Moved to `create-react-class`: `ClassicComponentClass`, `ClassicComponent`, `ClassicElement`, `ComponentSpec`, `Mixin`, `ReactChildren`, `ReactHTML`, `ReactSVG`, `SFCFactory`  \n* Disallow implicit return in refs: refs can now accept cleanup functions. When you return something else, we can’t tell if you intentionally returned something not meant to clean up or returned the wrong value. Implicit returns of anything but functions will now error.   \n* Require initial argument to `useRef`: The initial argument is now required to match `useState`, `createContext` etc  \n* Refs are mutable by default: Ref objects returned from `useRef()` are now always mutable instead of sometimes being immutable. This feature was too confusing for users and conflicted with legit cases where refs were managed by React and manually written to.  \n* Strict `ReactElement` typing: The props of React elements now default to `unknown` instead of `any` if the element is typed as `ReactElement`  \n* JSX namespace in TypeScript: The global `JSX` namespace is removed to improve interoperability with other libraries using JSX. Instead, the JSX namespace is available from the React package: `import { JSX } from 'react'`  \n* Better `useReducer` typings: Most `useReducer` usage should not require explicit type arguments.  \n  For example,  \n  ```diff\n  -useReducer<React.Reducer<State, Action>>(reducer)\n  +useReducer(reducer)\n  ```\n  or\n  ```diff\n  -useReducer<React.Reducer<State, Action>>(reducer)\n  +useReducer<State, Action>(reducer)\n  ```\n\n### All Changes\n\n#### React\n\n* Add support for async Actions ([\\#26621](https://github.com/facebook/react/pull/26621),

([@gaearon](https://github.com/gaearon) in [#24289](https://github.com/facebook/react/pull/24289))\n\n## 18.0.0 (March 29, 2022)\n\nBelow is a list of all new features, APIs, deprecations, and breaking changes.\nRead [React 18 release post](https://reactjs.org/blog/2022/03/29/react-v18.html) and [React 18 upgrade guide](https://reactjs.org/blog/2022/03/08/react-18-upgrade-guide.html) for more information.\n\n### New Features\n\n### React\n\n* `useId` is a new hook for generating unique IDs on both the client and server, while avoiding hydration mismatches. It is primarily useful for component libraries integrating with accessibility APIs that require unique IDs. This solves an issue that already exists in React 17 and below, but it’s even more important in React 18 because of how the new streaming server renderer delivers HTML out-of-order.\n* `startTransition` and `useTransition` let you mark some state updates as not urgent. Other state updates are considered urgent by default. React will allow urgent state updates (for example, updating a text input) to interrupt non-urgent state updates (for example, rendering a list of search results).\n* `useDeferredValue` lets you defer re-rendering a non-urgent part of the tree. It is similar to debouncing, but has a few advantages compared to it. There is no fixed time delay, so React will attempt the deferred render right after the first render is reflected on the screen. The deferred render is interruptible and doesn't block user input.\n* `useSyncExternalStore` is a new hook that allows external stores to support concurrent reads by forcing updates to the store to be synchronous. It removes the need for `useEffect` when implementing subscriptions to external data sources, and is recommended for any library that integrates with state external to React.\n* `useInsertionEffect` is a new hook that allows CSS-in-JS libraries to address performance issues of injecting styles in render. Unless you’ve already built a CSS-in-JS library we don’t expect you to ever use this. This hook will run after the DOM is mutated, but before layout effects read the new layout. This solves an issue that already exists in React 17 and below, but is even more important in React 18 because React yields to the browser during concurrent rendering, giving it a chance to recalculate layout.\n\n### React DOM Client\n\nThese new APIs are now exported from `react-dom/client`:\n\n* `createRoot`: New method to create a root to `render` or `unmount`. Use it instead of `ReactDOM.render`. New features in React 18 don't work without it.\n* `hydrateRoot`: New method to hydrate a server rendered application. Use it instead of `ReactDOM.hydrate` in conjunction with the new React DOM Server APIs. New features in React 18 don't work without it.\n\nBoth `createRoot` and `hydrateRoot` accept a new option called `onRecoverableError` in case you want to be notified when React recovers from errors during rendering or hydration for logging. By default, React will use [`reportError`](https://developer.mozilla.org/en-US/docs/Web/API/reportError), or `console.error` in the older browsers.\n\n### React DOM Server\n\nThese new APIs are now exported from `react-dom/server` and have full support for streaming Suspense on the server:\n\n* `renderToPipeableStream`: for streaming in Node environments.\n* `renderToReadableStream`: for modern edge runtime environments, such as Deno and Cloudflare workers.\n\nThe existing `renderToString` method keeps working but is discouraged.\n\n## Deprecations\n\n* `react-dom`: `ReactDOM.render` has been deprecated. Using it will warn and run your app in React 17 mode.\n* `react-dom`: `ReactDOM.hydrate` has been deprecated. Using it will warn and run your app in React 17 mode.\n* `react-dom`: `ReactDOM.unmountComponentAtNode` has been deprecated.\n* `react-dom`: `ReactDOM.renderSubtreeIntoContainer` has been deprecated.\n* `react-dom/server`: `ReactDOMServer.renderToNodeStream` has been deprecated.\n\n## Breaking Changes\n\n### React\n\n* **Automatic batching:** This release introduces a performance improvement that changes to the way React batches updates to do more batching automatically. See [Automatic batching for fewer renders in React 18](https://github.com/reactwg/react-18/discussions/21) for more info. In the rare case that you need to opt out, wrap the state update in `flushSync`.\n* **Stricter Strict Mode**: In the future, React will provide a feature that lets components preserve state between unmounts. To prepare for it, React 18 introduces a new development-only check to Strict Mode. React will automatically unmount and remount every component, whenever a component mounts for the first time, restoring the previous state on the second mount. If this breaks your app, consider removing Strict Mode until you can fix the components to be resilient to remounting with existing state.\n* **Consistent useEffect timing**: React now always synchronously flushes effect functions if the update was triggered during a discrete user input event such as a click or a keydown event. Previously, the behavior wasn't always predictable or consistent.\n* **Stricter hydration errors**: Hydration mismatches due to missing or extra text content are now treated like errors instead of warnings. React will no longer attempt to \"patch up\" individual nodes by inserting or deleting a node on the client in an attempt to match the server markup, and will revert to client rendering up to the closest `<Suspense>` boundary in the tree. This ensures the hydrated tree is consistent and avoids potential privacy and security holes that can be caused by hydration mismatches.\n* **Suspense trees are always consistent:** If a component suspends before it's fully added to the tree, React will not add it to the tree in an incomplete state or fire its effects. Instead, React will throw away the new tree completely, wait for the asynchronous operation to finish, and then retry rendering again from scratch. React will render the retry attempt concurrently, and without blocking the browser.\n* **Layout Effects with Suspense**: When a tree re-suspends and reverts to a fallback, React will now clean up layout effects, and then re-create them when the content inside the boundary is shown again. This fixes an issue which prevented component libraries from correctly measuring layout when used with Suspense.\n* **New JS Environment Requirements**: React now depends on modern browsers features including `Promise`, `Symbol`, and `Object.assign`. If you support older browsers and devices such as Internet Explorer which do not provide modern browser features natively or have non-compliant implementations, consider including a global polyfill in your bundled application.\n\n### Scheduler (Experimental)\n\n* Remove unstable `scheduler/tracing` API\n\n## Notable Changes\n\n### React\n\n* **Components can now render `undefined`:** React no longer throws if you return `undefined` from a component. This makes the allowed component return values consistent with values that are allowed in the middle of a component tree. We suggest to use a linter to prevent mistakes like forgetting a `return` statement before JSX.\n* **In tests, `act` warnings are now opt-in:** If you're running end-to-end tests, the `act` warnings are unnecessary. We've introduced an [opt-in](https://github.com/reactwg/react-18/discussions/102) mechanism so you can enable them only for unit tests where they are useful and beneficial.\n* **No warning about `setState` on unmounted components:** Previously, React warned about memory leaks when you call `setState` on an unmounted component. This warning was added for subscriptions, but people primarily run into it in scenarios where setting state is fine, and workarounds make the code worse. We've [removed](https://github.com/facebook/react/pull/22114) this warning.\n* **No suppression of console logs:** When you use Strict Mode, React renders each component twice to help you find unexpected side effects. In React 17, we've suppressed console logs for one of the two renders to make the logs easier to read. In response to [community feedback](https://github.com/facebook/react/issues/21783) about this being confusing, we've removed the suppression. Instead, if you have React DevTools installed, the second log's renders will be displayed in grey, and there will be an option (off by default) to suppress them completely.\n* **Improved memory usage:** React now cleans up more internal fields on unmount, making the impact from unfixed memory leaks that may exist in your application code less severe.\n\n### React DOM Server\n\n* **`renderToString`:** Will no longer error when suspending on the server. Instead, it will emit the fallback HTML for the closest `<Suspense>` boundary and then retry rendering the same content on the client. It is still recommended that you switch to a streaming API like `renderToPipeableStream` or `renderToReadableStream` instead.\n* **`renderToStaticMarkup`:** Will no longer error when suspending on the server. Instead, it will emit the fallback HTML for the closest `<Suspense>` boundary and retry rendering on the client.\n\n## All Changes\n\n## React\n\n* Add `useTransition` and `useDeferredValue` to separate urgent updates from transitions.

This fix is available in the latest `react-dom@16.4.2`, as well as in previous affected minor versions: `react-dom@16.0.1`, `react-dom@16.1.2`, `react-dom@16.2.1`, and `react-dom@16.3.3`. ([@gaearon](https://github.com/gaearon) in [#13302](https://github.com/facebook/react/pull/13302))\n\n## 16.0.0 (September 26, 2017)\n\n### New JS Environment Requirements\n\n * React 16 depends on the collection types [Map](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map) and [Set](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set), as well as [requestAnimationFrame](https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame). If you support older browsers and devices which may not yet provide these natively (e.g. <IE11), [you may want to include a polyfill](https://gist.github.com/gaearon/9a4d54653ae9c50af6c54b4e0e56b583).\n\n### New Features\n* Components can now return arrays and strings from `render`. (Docs coming soon!)\n* Improved error handling with introduction of \"error boundaries\". [Error boundaries](https://reactjs.org/blog/2017/07/26/error-handling-in-react-16.html) are React components that catch JavaScript errors anywhere in their child component tree, log those errors, and display a fallback UI instead of the component tree that crashed.\n* First-class support for declaratively rendering a subtree into another DOM node with `ReactDOM.createPortal()`. (Docs coming soon!)\n* Streaming mode for server side rendering is enabled with `ReactDOMServer.renderToNodeStream()` and `ReactDOMServer.renderToStaticNodeStream()`. ([@aickin](https://github.com/aickin) in [#10425](https://github.com/facebook/react/pull/10425), [#10044](https://github.com/facebook/react/pull/10044), [#10039](https://github.com/facebook/react/pull/10039), [#10024](https://github.com/facebook/react/pull/10024), [#9264](https://github.com/facebook/react/pull/9264), and others.)\n* [React DOM now allows passing non-standard attributes](https://reactjs.org/blog/2017/09/08/dom-attributes-in-react-16.html). ([@nhunzaker](https://github.com/nhunzaker) in [#10385](https://github.com/facebook/react/pull/10385), [10564](https://github.com/facebook/react/pull/10564), [#10495](https://github.com/facebook/react/pull/10495) and others)\n\n### Breaking Changes\n- There are several changes to the behavior of scheduling and lifecycle methods:\n  * `ReactDOM.render()` and `ReactDOM.unstable_renderIntoContainer()` now return `null` if called from inside a lifecycle method.\n    * To work around this, you can either use [the new portal API](https://github.com/facebook/react/issues/10309#issuecomment-318433235) or [refs](https://github.com/facebook/react/issues/10309#issuecomment-318434635).\n  * Minor changes to `setState` behavior:\n    * Calling `setState` with null no longer triggers an update. This allows you to decide in an updater function if you want to re-render.\n    * Calling `setState` directly in render always causes an update. This was not previously the case. Regardless, you should not be calling `setState` from render.\n    * `setState` callback (second argument) now fires immediately after `componentDidMount` / `componentDidUpdate` instead of after all components have rendered.\n  * When replacing `<A />` with `<B />`,  `B.componentWillMount` now always happens before  `A.componentWillUnmount`. Previously, `A.componentWillUnmount` could fire first in some cases.\n  * Previously, changing the `ref` to a component would always detach the ref before that component's render is called. Now, we change the `ref` later, when applying the changes to the DOM.\n  * It is not safe to re-render into a container that was modified by something other than React. This worked previously in some cases but was never supported. We now emit a warning in this case. Instead you should clean up your component trees using `ReactDOM.unmountComponentAtNode`. [See this example.](https://github.com/facebook/react/issues/10294#issuecomment-318820987)\n  * `componentDidUpdate` lifecycle no longer receives `prevContext` param. ([@bvaughn](https://github.com/bvaughn) in [#8631](https://github.com/facebook/react/pull/8631))\n  * Non-unique keys may now cause children to be duplicated and/or omitted. Using non-unique keys is not (and has never been) supported, but previously it was a hard error.\n  * Shallow renderer no longer calls `componentDidUpdate()` because DOM refs are not available. This also makes it consistent with `componentDidMount()` (which does not get called in previous versions either).\n  * Shallow renderer does not implement `unstable_batchedUpdates()` anymore.\n  * `ReactDOM.unstable_batchedUpdates` now only takes one extra argument after the callback.\n- The names and paths to the single-file browser builds have changed to emphasize the difference between development and production builds. For example:\n  - `react/dist/react.js` → `react/umd/react.development.js`\n  - `react/dist/react.min.js` → `react/umd/react.production.min.js`\n  - `react-dom/dist/react-dom.js` → `react-dom/umd/react-dom.development.js`\n  - `react-dom/dist/react-dom.min.js` → `react-dom/umd/react-dom.production.min.js`\n* The server renderer has been completely rewritten, with some improvements:\n  * Server rendering does not use markup validation anymore, and instead tries its best to attach to existing DOM, warning about inconsistencies. It also doesn't use comments for empty components and data-reactid attributes on each node anymore.\n  * Hydrating a server rendered container now has an explicit API. Use `ReactDOM.hydrate` instead of `ReactDOM.render` if you're reviving server rendered HTML. Keep using `ReactDOM.render` if you're just doing client-side rendering.\n* When \"unknown\" props are passed to DOM components, for valid values, React will now render them in the DOM. [See this post for more details.](https://reactjs.org/blog/2017/09/08/dom-attributes-in-react-16.html) ([@nhunzaker](https://github.com/nhunzaker) in [#10385](https://github.com/facebook/react/pull/10385), [10564](https://github.com/facebook/react/pull/10564), [#10495](https://github.com/facebook/react/pull/10495) and others)\n* Errors in the render and lifecycle methods now unmount the component tree by default. To prevent this, add [error boundaries](https://reactjs.org/blog/2017/07/26/error-handling-in-react-16.html) to the appropriate places in the UI.\n\n### Removed Deprecations\n\n- There is no `react-with-addons.js` build anymore. All compatible addons are published separately on npm, and have single-file browser versions if you need them.\n- The deprecations introduced in 15.x have been removed from the core package. `React.createClass` is now available as create-react-class, `React.PropTypes` as prop-types, `React.DOM` as react-dom-factories, react-addons-test-utils as react-dom/test-utils, and shallow renderer as react-test-renderer/shallow. See [15.5.0](https://reactjs.org/blog/2017/04/07/react-v15.5.0.html) and [15.6.0](https://reactjs.org/blog/2017/06/13/react-v15.6.0.html) blog posts for instructions on migrating code and automated codemods.\n\n## 15.7.0 (October 14, 2020)\n\n### React\n\n* Backport support for the [new JSX transform](https://reactjs.org/blog/2020/09/22/introducing-the-new-jsx-transform.html) to 15.x.

([@gaearon](https://github.com/gaearon) in [#6362](https://github.com/facebook/react/pull/6362))\n- Handle invalid arguments to `scryRenderedDOMComponentsWithClass` better. ([@ipeters90](https://github.com/ipeters90) in [#6529](https://github.com/facebook/react/pull/6529))\n\n### React Perf Add-on\n- Ignore DOM operations that occur outside the batch operation. ([@gaearon](https://github.com/gaearon) in [#6516](https://github.com/facebook/react/pull/6516))\n\n### React Native Renderer\n- These files are now shipped inside the React npm package. They have no impact on React core or ReactDOM.\n\n\n## 15.0.1 (April 8, 2016)\n\n### React\n- Restore `React.__spread` API to unbreak code compiled with some tools making use of this undocumented API. It is now officially deprecated. ([@zpao](https://github.com/zpao) in [#6444](https://github.com/facebook/react/pull/6444))\n\n### ReactDOM\n- Fixed issue resulting in loss of cursor position in controlled inputs. ([@sophiebits](https://github.com/sophiebits) in [#6449](https://github.com/facebook/react/pull/6449))\n\n\n## 15.0.0 (April 7, 2016)\n\n### Major changes\n\n- **Initial render now uses `document.createElement` instead of generating HTML.** Previously we would generate a large string of HTML and then set `node.innerHTML`. At the time, this was decided to be faster than using `document.createElement` for the majority of cases and browsers that we supported. Browsers have continued to improve and so overwhelmingly this is no longer true. By using `createElement` we can make other parts of React faster. ([@sophiebits](https://github.com/sophiebits) in [#5205](https://github.com/facebook/react/pull/5205))\n- **`data-reactid` is no longer on every node.** As a result of using `document.createElement`, we can prime the node cache as we create DOM nodes, allowing us to skip a potential lookup (which used the `data-reactid` attribute). Root nodes will have a `data-reactroot` attribute and server generated markup will still contain `data-reactid`. ([@sophiebits](https://github.com/sophiebits) in [#5205](https://github.com/facebook/react/pull/5205))\n- **No more extra `<span>`s.** ReactDOM will now render plain text nodes interspersed with comment nodes that are used for demarcation. This gives us the same ability to update individual pieces of text, without creating extra nested nodes. If you were targeting these `<span>`s in your CSS, you will need to adjust accordingly. You can always render them explicitly in your components. ([@mwiencek](https://github.com/mwiencek) in [#5753](https://github.com/facebook/react/pull/5753))\n- **Rendering `null` now uses comment nodes.** Previously `null` would render to `<noscript>` elements. We now use comment nodes. This may cause issues if making use of `:nth-child` CSS selectors. While we consider this rendering behavior an implementation detail of React, it's worth noting the potential problem. ([@sophiebits](https://github.com/sophiebits) in [#5451](https://github.com/facebook/react/pull/5451))\n- **Functional components can now return `null`.** We added support for [defining stateless components as functions](/react/blog/2015/09/10/react-v0.14-rc1.html#stateless-function-components) in React 0.14. However, React 0.14 still allowed you to define a class component without extending `React.Component` or using `React.createClass()`, so [we couldn’t reliably tell if your component is a function or a class](https://github.com/facebook/react/issues/5355), and did not allow returning `null` from it. This issue is solved in React 15, and you can now return `null` from any component, whether it is a class or a function. ([@jimfb](https://github.com/jimfb) in [#5884](https://github.com/facebook/react/pull/5884))\n- **Improved SVG support.** All SVG tags are now fully supported. (Uncommon SVG tags are not present on the `React.DOM` element helper, but JSX and `React.createElement` work on all tag names.) All SVG attributes that are implemented by the browsers should be supported too. If you find any attributes that we have missed, please [let us know in this issue](https://github.com/facebook/react/issues/1657). ([@zpao](https://github.com/zpao) in [#6243](https://github.com/facebook/react/pull/6243))\n\n### Breaking changes\n\n- **No more extra `<span>`s.**\n- **`React.cloneElement()` now resolves `defaultProps`.** We fixed a bug in `React.cloneElement()` that some components may rely on. If some of the `props` received by `cloneElement()` are `undefined`, it used to return an element with `undefined` values for those props. We’re changing it to be consistent with `createElement()`. Now any `undefined` props passed to `cloneElement()` are resolved to the corresponding component’s `defaultProps`. ([@truongduy134](https://github.com/truongduy134) in [#5997](https://github.com/facebook/react/pull/5997))\n- **`ReactPerf.getLastMeasurements()` is opaque.** This change won’t affect applications but may break some third-party tools. We are [revamping `ReactPerf` implementation](https://github.com/facebook/react/pull/6046) and plan to release it during the 15.x cycle. The internal performance measurement format is subject to change so, for the time being, we consider the return value of `ReactPerf.getLastMeasurements()` an opaque data structure that should not be relied upon. ([@gaearon](https://github.com/gaearon) in [#6286](https://github.com/facebook/react/pull/6286))\n\n#### Removed deprecations\n\nThese deprecations were introduced nine months ago in v0.14 with a warning and are removed:\n\n- Deprecated APIs are removed from the `React` top-level export: `findDOMNode`, `render`, `renderToString`, `renderToStaticMarkup`, and `unmountComponentAtNode`. As a reminder, they are now available on `ReactDOM` and `ReactDOMServer`. ([@jimfb](https://github.com/jimfb) in [#5832](https://github.com/facebook/react/pull/5832))\n- Deprecated addons are removed: `batchedUpdates` and `cloneWithProps`. ([@jimfb](https://github.com/jimfb) in [#5859](https://github.com/facebook/react/pull/5859), [@zpao](https://github.com/zpao) in [#6016](https://github.com/facebook/react/pull/6016))\n- Deprecated component instance methods are removed: `setProps`, `replaceProps`, and `getDOMNode`. ([@jimfb](https://github.com/jimfb) in [#5570](https://github.com/facebook/react/pull/5570))\n- Deprecated CommonJS `react/addons` entry point is removed. As a reminder, you should use separate `react-addons-*` packages instead. This only applies if you use the CommonJS builds. ([@gaearon](https://github.com/gaearon) in [#6285](https://github.com/facebook/react/pull/6285))\n- Passing `children` to void elements like `<input>` was deprecated, and now throws an error. ([@jonhester](https://github.com/jonhester) in [#3372](https://github.com/facebook/react/pull/3372))\n- React-specific properties on DOM `refs` (e.g. `this.refs.div.props`) were deprecated, and are removed now. ([@jimfb](https://github.com/jimfb) in [#5495](https://github.com/facebook/react/pull/5495))\n\n### New deprecations, introduced with a warning\n\nEach of these changes will continue to work as before with a new warning until the release of React 16 so you can upgrade your code gradually.\n\n- `LinkedStateMixin` and `valueLink` are now deprecated due to very low popularity. If you need this, you can use a wrapper component that implements the same behavior: [react-linked-input](https://www.npmjs.com/package/react-linked-input). ([@jimfb](https://github.com/jimfb) in [#6127](https://github.com/facebook/react/pull/6127))\n- Future versions of React will treat `<input value={null}>` as a request to clear the input. However, React 0.14 has been ignoring `value={null}`. React 15 warns you on a `null` input value and offers you to clarify your intention. To fix the warning, you may explicitly pass an empty string to clear a controlled input, or pass `undefined` to make the input uncontrolled. ([@antoaravinth](https://github.com/antoaravinth) in [#5048](https://github.com/facebook/react/pull/5048))\n- `ReactPerf.printDOM()` was renamed to `ReactPerf.printOperations()`, and `ReactPerf.getMeasurementsSummaryMap()` was renamed to `ReactPerf.getWasted()`. ([@gaearon](https://github.com/gaearon) in [#6287](https://github.com/facebook/react/pull/6287))\n\n### New helpful warnings\n\n- If you use a minified copy of the _development_ build, React DOM kindly encourages you to use the faster production build instead. ([@sophiebits](https://github.com/sophiebits) in [#5083](https://github.com/facebook/react/pull/5083))\n- React DOM: When specifying a unit-less CSS value as a string, a future version will not add `px` automatically. This version now warns in this case (ex: writing `style={{width: '300'}}`. Unitless *number* values like `width: 300` are unchanged. ([@pluma](https://github.com/pluma) in [#5140](https://github.com/facebook/react/pull/5140))\n- Synthetic Events will now warn when setting and accessing properties (which will not get cleared appropriately), as well as warn on access after an event has been returned to the pool. ([@kentcdodds](https://github.com/kentcdodds) in [#5940](https://github.com/facebook/react/pull/5940) and [@koba04](https://github.com/koba04) in [#5947](https://github.com/facebook/react/pull/5947))\n- Elements will now warn when attempting to read `ref` and `key` from the props. ([@prometheansacrifice](https://github.com/prometheansacrifice) in [#5744](https://github.com/facebook/react/pull/5744))\n- React will now warn if you pass a different `props` object to `super()` in the constructor. ([@prometheansacrifice](https://github.com/prometheansacrifice) in [#5346](https://github.com/facebook/react/pull/5346))\n- React will now warn if you call `setState()` inside `getChildContext()`. ([@raineroviir](https://github.com/raineroviir) in [#6121](https://github.com/facebook/react/pull/6121))\n- React DOM now attempts to warn for mistyped event handlers on DOM elements, such as `onclick` which should be `onClick`. ([@ali](https://github.com/ali) in [#5361](https://github.com/facebook/react/pull/5361))\n- React DOM now warns about `NaN` values in `style`. ([@jontewks](https://github.com/jontewks) in [#5811](https://github.com/facebook/react/pull/5811))\n- React DOM now warns if you specify both `value` and `defaultValue` for an input. ([@mgmcdermott](https://github.com/mgmcdermott) in [#5823](https://github.com/facebook/react/pull/5823))\n- React DOM now warns if an input switches between being controlled and uncontrolled. ([@TheBlasfem](https://github.com/TheBlasfem) in [#5864](https://github.com/facebook/react/pull/5864))\n- React DOM now warns if you specify `onFocusIn` or `onFocusOut` handlers as they are unnecessary in React. ([@jontewks](https://github.com/jontewks) in [#6296](https://github.com/facebook/react/pull/6296))\n- React now prints a descriptive error message when you pass an invalid callback as the last argument to `ReactDOM.render()`, `this.setState()`, or `this.forceUpdate()`. ([@conorhastings](https://github.com/conorhastings) in [#5193](https://github.com/facebook/react/pull/5193) and [@gaearon](https://github.com/gaearon) in [#6310](https://github.com/facebook/react/pull/6310))\n- Add-Ons: `TestUtils.Simulate()` now prints a helpful message if you attempt to use it with shallow rendering. ([@conorhastings](https://github.com/conorhastings) in [#5358](https://github.com/facebook/react/pull/5358))\n- PropTypes: `arrayOf()` and `objectOf()` provide better error messages for invalid arguments. ([@chicoxyzzy](https://github.com/chicoxyzzy) in [#5390](https://github.com/facebook/react/pull/5390))\n\n### Notable bug fixes\n\n- Fixed multiple small memory leaks. ([@sophiebits](https://github.com/sophiebits) in [#4983](https://github.com/facebook/react/pull/4983) and [@victor-homyakov](https://github.com/victor-homyakov) in [#6309](https://github.com/facebook/react/pull/6309))\n- Input events are handled more reliably in IE 10 and IE 11; spurious events no longer fire when using a placeholder. ([@jquense](https://github.com/jquense) in [#4051](https://github.com/facebook/react/pull/4051))\n- The `componentWillReceiveProps()` lifecycle method is now consistently called when `context` changes. ([@milesj](https://github.com/milesj) in [#5787](https://github.com/facebook/react/pull/5787))\n- `React.cloneElement()` doesn’t append slash to an existing `key` when used inside `React.Children.map()`. ([@ianobermiller](https://github.com/ianobermiller) in [#5892](https://github.com/facebook/react/pull/5892))\n- React DOM now supports the `cite` and `profile` HTML attributes. ([@AprilArcus](https://github.com/AprilArcus) in [#6094](https://github.com/facebook/react/pull/6094) and [@saiichihashimoto](https://github.com/saiichihashimoto) in [#6032](https://github.com/facebook/react/pull/6032))\n- React DOM now supports `cssFloat`, `gridRow` and `gridColumn` CSS properties. ([@stevenvachon](https://github.com/stevenvachon) in [#6133](https://github.com/facebook/react/pull/6133) and  [@mnordick](https://github.com/mnordick) in [#4779](https://github.com/facebook/react/pull/4779))\n- React DOM now correctly handles `borderImageOutset`, `borderImageWidth`, `borderImageSlice`, `floodOpacity`, `strokeDasharray`, and `strokeMiterlimit` as unitless CSS properties. ([@rofrischmann](https://github.com/rofrischmann) in [#6210](https://github.com/facebook/react/pull/6210) and [#6270](https://github.com/facebook/react/pull/6270))\n- React DOM now supports the `onAnimationStart`, `onAnimationEnd`, `onAnimationIteration`, `onTransitionEnd`, and `onInvalid` events. Support for `onLoad` has been added to `object` elements. ([@tomduncalf](https://github.com/tomduncalf) in [#5187](https://github.com/facebook/react/pull/5187),  [@milesj](https://github.com/milesj) in [#6005](https://github.com/facebook/react/pull/6005), and [@ara4n](https://github.com/ara4n) in [#5781](https://github.com/facebook/react/pull/5781))\n- React DOM now defaults to using DOM attributes instead of properties, which fixes a few edge case bugs. Additionally the nullification of values (ex: `href={null}`) now results in the forceful removal, no longer trying to set to the default value used by browsers in the absence of a value. ([@syranide](https://github.com/syranide) in [#1510](https://github.com/facebook/react/pull/1510))\n- React DOM does not mistakenly coerce `children` to strings for Web Components. ([@jimfb](https://github.com/jimfb) in [#5093](https://github.com/facebook/react/pull/5093))\n- React DOM now correctly normalizes SVG `<use>` events. ([@edmellum](https://github.com/edmellum) in [#5720](https://github.com/facebook/react/pull/5720))\n- React DOM does not throw if a `<select>` is unmounted while its `onChange` handler is executing. ([@sambev](https://github.com/sambev) in [#6028](https://github.com/facebook/react/pull/6028))\n- React DOM does not throw in Windows 8 apps. ([@Andrew8xx8](https://github.com/Andrew8xx8) in [#6063](https://github.com/facebook/react/pull/6063))\n- React DOM does not throw when asynchronously unmounting a child with a `ref`. ([@yiminghe](https://github.com/yiminghe) in [#6095](https://github.com/facebook/react/pull/6095))\n- React DOM no longer forces synchronous layout because of scroll position tracking. ([@syranide](https://github.com/syranide) in [#2271](https://github.com/facebook/react/pull/2271))\n- `Object.is` is used in a number of places to compare values, which leads to fewer false positives, especially involving `NaN`. In particular, this affects the `shallowCompare` add-on. ([@chicoxyzzy](https://github.com/chicoxyzzy) in [#6132](https://github.com/facebook/react/pull/6132))\n- Add-Ons: ReactPerf no longer instruments adding or removing an event listener because they don’t really touch the DOM due to event delegation. ([@antoaravinth](https://github.com/antoaravinth) in [#5209](https://github.com/facebook/react/pull/5209))\n\n### Other improvements\n\n- React now uses `loose-envify` instead of `envify` so it installs fewer transitive dependencies. ([@qerub](https://github.com/qerub) in [#6303](https://github.com/facebook/react/pull/6303))\n- Shallow renderer now exposes `getMountedInstance()`. ([@glenjamin](https://github.com/glenjamin) in [#4918](https://github.com/facebook/react/pull/4918))\n- Shallow renderer now returns the rendered output from `render()`. ([@simonewebdesign](https://github.com/simonewebdesign) in [#5411](https://github.com/facebook/react/pull/5411))\n- React no longer depends on ES5 *shams* for `Object.create` and `Object.freeze` in older environments. It still, however, requires ES5 *shims* in those environments. ([@dgreensp](https://github.com/dgreensp) in [#4959](https://github.com/facebook/react/pull/4959))\n- React DOM now allows `data-` attributes with names that start with numbers. ([@nLight](https://github.com/nLight) in [#5216](https://github.com/facebook/react/pull/5216))\n- React DOM adds a new `suppressContentEditableWarning` prop for components like [Draft.js](https://draftjs.org/) that intentionally manage `contentEditable` children with React. ([@mxstbr](https://github.com/mxstbr) in [#6112](https://github.com/facebook/react/pull/6112))\n- React improves the performance for `createClass()` on complex specs. ([@sophiebits](https://github.com/sophiebits) in [#5550](https://github.com/facebook/react/pull/5550))\n\n## 0.14.10 (October 14, 2020)\n\n### React\n\n* Backport support for the [new JSX transform](https://reactjs.org/blog/2020/09/22/introducing-the-new-jsx-transform.html) to 0.14.x. ([@lunaruan](https://github.com/lunaruan) in [#18299](https://github.com/facebook/react/pull/18299) and [@gaearon](https://github.com/gaearon) in [#20024](https://github.com/facebook/react/pull/20024))\n\n## 0.14.8 (March 29, 2016)\n\n### React\n- Fixed memory leak when rendering on the server\n\n## 0.14.7 (January 28, 2016)\n\n### React\n- Fixed bug with `<option>` tags when using `dangerouslySetInnerHTML`\n- Fixed memory leak in synthetic event system\n\n### React TestUtils Add-on\n- Fixed bug with calling `setState` in `componentWillMount` when using shallow rendering\n\n\n## 0.14.6 (January 6, 2016)\n\n### React\n- Updated `fbjs` dependency to pick up change affecting handling of undefined document.\n\n\n## 0.14.5 (December 29, 2015)\n\n### React\n- More minor internal changes for better compatibility with React Native\n\n\n## 0.14.4 (December 29, 2015)\n\n### React\n- Minor internal changes for better compatibility with React Native\n\n### React DOM\n- The `autoCapitalize` and `autoCorrect` props are now set as attributes in the DOM instead of properties to improve cross-browser compatibility\n- Fixed bug with controlled `<select>` elements not handling updates properly\n\n### React Perf Add-on\n- Some DOM operation names have been updated for clarity in the output of `.printDOM()`\n\n\n## 0.14.3 (November 18, 2015)\n\n### React DOM\n- Added support for `nonce` attribute for `<script>` and `<style>` elements\n- Added support for `reversed` attribute for `<ol>` elements\n\n### React TestUtils Add-on\n- Fixed bug with shallow rendering and function refs\n\n### React CSSTransitionGroup Add-on\n- Fixed bug resulting in timeouts firing incorrectly when mounting and unmounting rapidly\n\n### React on Bower\n- Added `react-dom-server.js` to expose `renderToString` and `renderToStaticMarkup` for usage in the browser\n\n\n## 0.14.2 (November 2, 2015)\n\n### React DOM\n- Fixed bug with development build preventing events from firing in some versions of Internet Explorer & Edge\n- Fixed bug with development build when using es5-sham in older versions of Internet Explorer\n- Added support for `integrity` attribute\n- Fixed bug resulting in `children` prop being coerced to a string for custom elements, which was not the desired behavior\n- Moved `react` from `dependencies` to `peerDependencies` to match expectations and align with `react-addons-*` packages\n\n\n## 0.14.1 (October 28, 2015)\n\n### React DOM\n- Fixed bug where events wouldn't fire in old browsers when using React in development mode\n- Fixed bug preventing use of `dangerouslySetInnerHTML` with Closure Compiler Advanced mode\n- Added support for `srcLang`, `default`, and `kind` attributes for `<track>` elements\n- Added support for `color` attribute\n- Ensured legacy `.props` access on DOM nodes is updated on re-renders\n\n### React TestUtils Add-on\n- Fixed `scryRenderedDOMComponentsWithClass` so it works with SVG\n\n### React CSSTransitionGroup Add-on\n- Fix bug preventing `0` to be used as a timeout value\n\n### React on Bower\n- Added `react-dom.js` to `main` to improve compatibility with tooling\n\n\n## 0.14.0 (October 7, 2015)\n\n### Major changes\n\n- Split the main `react` package into two: `react` and `react-dom`.  This paves the way to writing components that can be shared between the web version of React and React Native.  This means you will need to include both files and some functions have been moved from `React` to `ReactDOM`.\n- Addons have been moved to separate packages (`react-addons-clone-with-props`, `react-addons-create-fragment`, `react-addons-css-transition-group`, `react-addons-linked-state-mixin`, `react-addons-perf`, `react-addons-pure-render-mixin`, `react-addons-shallow-compare`, `react-addons-test-utils`, `react-addons-transition-group`, `react-addons-update`, `ReactDOM.unstable_batchedUpdates`).\n- Stateless functional components - React components were previously created using React.createClass or using ES6 classes.  This release adds a [new syntax](https://reactjs.org/docs/reusable-components.html#stateless-functions) where a user defines a single [stateless render function](https://reactjs.org/docs/reusable-components.html#stateless-functions) (with one parameter: `props`) which returns a JSX element, and this function may be used as a component.\n- Refs to DOM components as the DOM node itself. Previously the only useful thing you can do with a DOM component is call `getDOMNode()` to get the underlying DOM node. Starting with this release, a ref to a DOM component _is_ the actual DOM node. **Note that refs to custom (user-defined) components work exactly as before; only the built-in DOM components are affected by this change.**\n\n\n### Breaking changes\n\n- `React.initializeTouchEvents` is no longer necessary and has been removed completely. Touch events now work automatically.\n- Add-Ons: Due to the DOM node refs change mentioned above, `TestUtils.findAllInRenderedTree` and related helpers are no longer able to take a DOM component, only a custom component.\n- The `props` object is now frozen, so mutating props after creating a component element is no longer supported. In most cases, [`React.cloneElement`](https://reactjs.org/docs/react-api.html#cloneelement) should be used instead. This change makes your components easier to reason about and enables the compiler optimizations mentioned above.\n- Plain objects are no longer supported as React children; arrays should be used instead. You can use the [`createFragment`](https://reactjs.org/docs/create-fragment.html) helper to migrate, which now returns an array.\n- Add-Ons: `classSet` has been removed. Use [classnames](https://github.com/JedWatson/classnames) instead.\n- Web components (custom elements) now use native property names.  Eg: `class` instead of `className`.\n\n### Deprecations\n\n- `this.getDOMNode()` is now deprecated and `ReactDOM.findDOMNode(this)` can be used instead. Note that in the common case, `findDOMNode` is now unnecessary since a ref to the DOM component is now the actual DOM node.\n- `setProps` and `replaceProps` are now deprecated. Instead, call ReactDOM.render again at the top level with the new props.\n- ES6 component classes must now extend `React.Component` in order to enable stateless function components. The [ES3 module pattern](https://reactjs.org/blog/2015/01/27/react-v0.13.0-beta-1.html#other-languages) will continue to work.\n- Reusing and mutating a `style` object between renders has been deprecated. This mirrors our change to freeze the `props` object.\n- Add-Ons: `cloneWithProps` is now deprecated. Use [`React.cloneElement`](https://reactjs.org/docs/react-api.html#cloneelement) instead (unlike `cloneWithProps`, `cloneElement` does not merge `className` or `style` automatically; you can merge them manually if needed).\n- Add-Ons: To improve reliability, `CSSTransitionGroup` will no longer listen to transition events. Instead, you should specify transition durations manually using props such as `transitionEnterTimeout={500}`.\n\n### Notable enhancements\n\n- Added `React.Children.toArray` which takes a nested children object and returns a flat array with keys assigned to each child. This helper makes it easier to manipulate collections of children in your `render` methods, especially if you want to reorder or slice `this.props.children` before passing it down. In addition, `React.Children.map` now returns plain arrays too.\n- React uses `console.error` instead of `console.warn` for warnings so that browsers show a full stack trace in the console. (Our warnings appear when you use patterns that will break in future releases and for code that is likely to behave unexpectedly, so we do consider our warnings to be “must-fix” errors.)\n- Previously, including untrusted objects as React children [could result in an XSS security vulnerability](http://danlec.com/blog/xss-via-a-spoofed-react-element). This problem should be avoided by properly validating input at the application layer and by never passing untrusted objects around your application code. As an additional layer of protection, [React now tags elements](https://github.com/facebook/react/pull/4832) with a specific [ES2015 (ES6) `Symbol`](http://www.2ality.com/2014/12/es6-symbols.html) in browsers that support it, in order to ensure that React never considers untrusted JSON to be a valid element. If this extra security protection is important to you, you should add a `Symbol` polyfill for older browsers, such as the one included by [Babel’s polyfill](https://babeljs.io/docs/usage/polyfill/).\n- When possible, React DOM now generates XHTML-compatible markup.\n- React DOM now supports these standard HTML attributes: `capture`, `challenge`, `inputMode`, `is`, `keyParams`, `keyType`, `minLength`, `summary`, `wrap`. It also now supports these non-standard attributes: `autoSave`, `results`, `security`.\n- React DOM now supports these SVG attributes, which render into namespaced attributes: `xlinkActuate`, `xlinkArcrole`, `xlinkHref`, `xlinkRole`, `xlinkShow`, `xlinkTitle`, `xlinkType`, `xmlBase`, `xmlLang`, `xmlSpace`.\n- The `image` SVG tag is now supported by React DOM.\n- In React DOM, arbitrary attributes are supported on custom elements (those with a hyphen in the tag name or an `is=\"...\"` attribute).\n- React DOM now supports these media events on `audio` and `video` tags: `onAbort`, `onCanPlay`, `onCanPlayThrough`, `onDurationChange`, `onEmptied`, `onEncrypted`, `onEnded`, `onError`, `onLoadedData`, `onLoadedMetadata`, `onLoadStart`, `onPause`, `onPlay`, `onPlaying`, `onProgress`, `onRateChange`, `onSeeked`, `onSeeking`, `onStalled`, `onSuspend`, `onTimeUpdate`, `onVolumeChange`, `onWaiting`.\n- Many small performance improvements have been made.\n- Many warnings show more context than before.\n- Add-Ons: A [`shallowCompare`](https://github.com/facebook/react/pull/3355) add-on has been added as a migration path for `PureRenderMixin` in ES6 classes.\n- Add-Ons: `CSSTransitionGroup` can now use [custom class names](https://github.com/facebook/react/blob/48942b85/docs/docs/10.1-animation.md#custom-classes) instead of appending `-enter-active` or similar to the transition name.\n\n### New helpful warnings\n\n- React DOM now warns you when nesting HTML elements invalidly, which helps you avoid surprising errors during updates.\n- Passing `document.body` directly as the container to `ReactDOM.render` now gives a warning as doing so can cause problems with browser extensions that modify the DOM.\n- Using multiple instances of React together is not supported, so we now warn when we detect this case to help you avoid running into the resulting problems.\n\n### Notable bug fixes\n\n- Click events are handled by React DOM more reliably in mobile browsers, particularly in Mobile Safari.\n- SVG elements are created with the correct namespace in more cases.\n- React DOM now renders `<option>` elements with multiple text children properly and renders `<select>` elements on the server with the correct option selected.\n- When two separate copies of React add nodes to the same document (including when a browser extension uses React), React DOM tries harder not to throw exceptions during event handling.\n- Using non-lowercase HTML tag names in React DOM (e.g., `React.createElement('DIV')`) no longer causes problems, though we continue to recommend lowercase for consistency with the JSX tag name convention (lowercase names refer to built-in components, capitalized names refer to custom components).\n- React DOM understands that these CSS properties are unitless and does not append “px” to their values: `animationIterationCount`, `boxOrdinalGroup`, `flexOrder`, `tabSize`, `stopOpacity`.\n- Add-Ons: When using the test utils, `Simulate.mouseEnter` and `Simulate.mouseLeave` now work.\n- Add-Ons: ReactTransitionGroup now correctly handles multiple nodes being removed simultaneously.\n\n\n### React Tools / Babel\n\n#### Breaking Changes\n\n- The `react-tools` package and `JSXTransformer.js` browser file [have been deprecated](https://reactjs.org/blog/2015/06/12/deprecating-jstransform-and-react-tools.html). You can continue using version `0.13.3` of both, but we no longer support them and recommend migrating to [Babel](https://babeljs.io), which has built-in support for React and JSX.\n\n#### New Features\n\n- Babel 5.8.24 introduces **Inlining React elements:** The `optimisation.react.inlineElements` transform converts JSX elements to object literals like `{type: 'div', props: ...}` instead of calls to `React.createElement`.  This should only be enabled in production, since it disables some development warnings/checks.\n- Babel 5.8.24 introduces **Constant hoisting for React elements:** The `optimisation.react.constantElements` transform hoists element creation to the top level for subtrees that are fully static, which reduces calls to `React.createElement` and the resulting allocations. More importantly, it tells React that the subtree hasn’t changed so React can completely skip it when reconciling.  This should only be enabled in production, since it disables some development warnings/checks.\n\n\n## 0.13.3 (May 8, 2015)\n\n### React Core\n\n#### New Features\n\n* Added `clipPath` element and attribute for SVG\n* Improved warnings for deprecated methods in plain JS classes\n\n#### Bug Fixes\n\n* Loosened `dangerouslySetInnerHTML` restrictions so `{__html: undefined}` will no longer throw\n* Fixed extraneous context warning with non-pure `getChildContext`\n* Ensure `replaceState(obj)` retains prototype of `obj`\n\n### React with Add-ons\n\n### Bug Fixes\n\n* Test Utils: Ensure that shallow rendering works when components define `contextTypes`\n\n\n## 0.13.2 (April 18, 2015)\n\n### React Core\n\n#### New Features\n\n* Added `strokeDashoffset`, `flexPositive`, `flexNegative` to the list of unitless CSS properties\n* Added support for more DOM properties:\n  * `scoped` - for `<style>` elements\n  * `high`, `low`, `optimum` - for `<meter>` elements\n  * `unselectable` - IE-specific property to prevent user selection\n\n#### Bug Fixes\n\n* Fixed a case where re-rendering after rendering null didn't properly pass context\n* Fixed a case where re-rendering after rendering with `style={null}` didn't properly update `style`\n* Update `uglify` dependency to prevent a bug in IE8\n* Improved warnings\n\n### React with Add-Ons\n\n#### Bug Fixes\n\n* Immutability Helpers: Ensure it supports `hasOwnProperty` as an object key\n\n### React Tools\n\n* Improve documentation for new options\n\n\n## 0.13.1 (March 16, 2015)\n\n### React Core\n\n#### Bug Fixes\n\n* Don't throw when rendering empty `<select>` elements\n* Ensure updating `style` works when transitioning from `null`\n\n### React with Add-Ons\n\n#### Bug Fixes\n\n* TestUtils: Don't warn about `getDOMNode` for ES6 classes\n* TestUtils: Ensure wrapped full page components (`<html>`, `<head>`, `<body>`) are treated as DOM components\n* Perf: Stop double-counting DOM components\n\n### React Tools\n\n#### Bug Fixes\n\n* Fix option parsing for `--non-strict-es6module`\n\n\n## 0.13.0 (March 10, 2015)\n\n### React Core\n\n#### Breaking Changes\n\n* Deprecated patterns that warned in 0.12 no longer work: most prominently, calling component classes without using JSX or React.createElement and using non-component functions with JSX or createElement\n* Mutating `props` after an element is created is deprecated and will cause warnings in development mode; future versions of React will incorporate performance optimizations assuming that props aren't mutated\n* Static methods (defined in `statics`) are no longer autobound to the component class\n* `ref` resolution order has changed slightly such that a ref to a component is available immediately after its `componentDidMount` method is called; this change should be observable only if your component calls a parent component's callback within your `componentDidMount`, which is an anti-pattern and should be avoided regardless\n* Calls to `setState` in life-cycle methods are now always batched and therefore asynchronous. Previously the first call on the first mount was synchronous.\n* `setState` and `forceUpdate` on an unmounted component now warns instead of throwing. That avoids a possible race condition with Promises.\n* Access to most internal properties has been completely removed, including `this._pendingState` and `this._rootNodeID`.\n\n#### New Features\n\n* Support for using ES6 classes to build React components; see the [v0.13.0 beta 1 notes](https://reactjs.org/blog/2015/01/27/react-v0.13.0-beta-1.html) for details.\n* Added new top-level API `React.findDOMNode(component)`, which should be used in place of `component.getDOMNode()`. The base class for ES6-based components will not have `getDOMNode`. This change will enable some more patterns moving forward.\n* Added a new top-level API `React.cloneElement(el, props)` for making copies of React elements – see the [v0.13 RC2 notes](https://reactjs.org/blog/2015/03/03/react-v0.13-rc2.html#react.cloneelement) for more details.\n* New `ref` style, allowing a callback to be used in place of a name: `<Photo ref={(c) => this._photo = c} />` allows you to reference the component with `this._photo` (as opposed to `ref=\"photo\"` which gives `this.refs.photo`).\n* `this.setState()` can now take a function as the first argument for transactional state updates, such as `this.setState((state, props) => ({count: state.count + 1}));` – this means that you no longer need to use `this._pendingState`, which is now gone.\n* Support for iterators and immutable-js sequences as children.\n\n#### Deprecations\n\n* `ComponentClass.type` is deprecated. Just use `ComponentClass` (usually as `element.type === ComponentClass`).\n* Some methods that are available on `createClass`-based components are removed or deprecated from ES6 classes (`getDOMNode`, `replaceState`, `isMounted`, `setProps`, `replaceProps`).\n\n### React with Add-Ons\n\n#### New Features\n\n* [`React.addons.createFragment` was added](https://reactjs.org/docs/create-fragment.html) for adding keys to entire sets of children.\n\n#### Deprecations\n\n* `React.addons.classSet` is now deprecated. This functionality can be replaced with several freely available modules. [classnames](https://www.npmjs.com/package/classnames) is one such module.\n* Calls to `React.addons.cloneWithProps` can be migrated to use `React.cloneElement` instead – make sure to merge `style` and `className` manually if desired.\n\n### React Tools\n\n#### Breaking Changes\n\n* When transforming ES6 syntax, `class` methods are no longer enumerable by default, which requires `Object.defineProperty`; if you support browsers such as IE8, you can pass `--target es3` to mirror the old behavior\n\n#### New Features\n\n* `--target` option is available on the jsx command, allowing users to specify and ECMAScript version to target.\n  * `es5` is the default.\n  * `es3` restores the previous default behavior. An additional transform is added here to ensure the use of reserved words as properties is safe (eg `this.static` will become `this['static']` for IE8 compatibility).\n* The transform for the call spread operator has also been enabled.\n\n### JSXTransformer\n\n#### Breaking Changes\n\n* The return value of `transform` now contains `sourceMap` as a JS object already, not an instance of `SourceMapGenerator`.\n\n### JSX\n\n#### Breaking Changes\n* A change was made to how some JSX was parsed, specifically around the use of `>` or `}` when inside an element. Previously it would be treated as a string but now it will be treated as a parse error. The [`jsx_orphaned_brackets_transformer`](https://www.npmjs.com/package/jsx_orphaned_brackets_transformer) package on npm can be used to find and fix potential issues in your JSX code.\n\n\n## 0.12.2 (December 18, 2014)\n\n### React Core\n\n* Added support for more HTML attributes: `formAction`, `formEncType`, `formMethod`, `formTarget`, `marginHeight`, `marginWidth`\n* Added `strokeOpacity` to the list of unitless CSS properties\n* Removed trailing commas (allows npm module to be bundled and used in IE8)\n* Fixed bug resulting in error when passing `undefined` to `React.createElement` - now there is a useful warning\n\n### React Tools\n\n* JSX-related transforms now always use double quotes for props and `displayName`\n\n\n## 0.12.1 (November 18, 2014)\n\n### React Tools\n\n* Types transform updated with latest support\n* jstransform version updated with improved ES6 transforms\n* Explicit Esprima dependency removed in favor of using Esprima information exported by jstransform\n\n\n## 0.12.0 (October 28, 2014)\n\n### React Core\n\n#### Breaking Changes\n\n* `key` and `ref` moved off props object, now accessible on the element directly\n* React is now BSD licensed with accompanying Patents grant\n* Default prop resolution has moved to Element creation time instead of mount time, making them effectively static\n* `React.__internals` is removed - it was exposed for DevTools which no longer needs access\n* Composite Component functions can no longer be called directly - they must be wrapped with `React.createFactory` first. This is handled for you when using JSX.\n\n#### New Features\n\n* Spread operator (`{...}`) introduced to deprecate `this.transferPropsTo`\n* Added support for more HTML attributes: `acceptCharset`, `classID`, `manifest`\n\n#### Deprecations\n\n* `React.renderComponent` --> `React.render`\n* `React.renderComponentToString` --> `React.renderToString`\n* `React.renderComponentToStaticMarkup` --> `React.renderToStaticMarkup`\n* `React.isValidComponent` --> `React.isValidElement`\n* `React.PropTypes.component` --> `React.PropTypes.element`\n* `React.PropTypes.renderable` --> `React.PropTypes.node`\n* **DEPRECATED** `React.isValidClass`\n* **DEPRECATED** `instance.transferPropsTo`\n* **DEPRECATED** Returning `false` from event handlers to preventDefault\n* **DEPRECATED** Convenience Constructor usage as function, instead wrap with `React.createFactory`\n* **DEPRECATED** use of `key={null}` to assign implicit keys\n\n#### Bug Fixes\n\n* Better handling of events and updates in nested results, fixing value restoration in \"layered\" controlled components\n* Correctly treat `event.getModifierState` as case sensitive\n* Improved normalization of `event.charCode`\n* Better error stacks when involving autobound methods\n* Removed DevTools message when the DevTools are installed\n* Correctly detect required language features across browsers\n* Fixed support for some HTML attributes:\n  * `list` updates correctly now\n  * `scrollLeft`, `scrollTop` removed, these should not be specified as props\n* Improved error messages\n\n### React With Addons\n\n#### New Features\n\n* `React.addons.batchedUpdates` added to API for hooking into update cycle\n\n#### Breaking Changes\n\n* `React.addons.update` uses `assign` instead of `copyProperties` which does `hasOwnProperty` checks. Properties on prototypes will no longer be updated correctly.\n\n#### Bug Fixes\n\n* Fixed some issues with CSS Transitions\n\n### JSX\n\n#### Breaking Changes\n\n* Enforced convention: lower case tag names are always treated as HTML tags, upper case tag names are always treated as composite components\n* JSX no longer transforms to simple function calls\n\n#### New Features\n\n* `@jsx React.DOM` no longer required\n* spread (`{...}`) operator introduced to allow easier use of props\n\n#### Bug Fixes\n\n* JSXTransformer: Make sourcemaps an option when using APIs directly (eg, for react-rails)\n\n\n## 0.11.2 (September 16, 2014)\n\n### React Core\n\n#### New Features\n\n* Added support for `<dialog>` element and associated `open` attribute\n* Added support for `<picture>` element and associated `media` and `sizes` attributes\n* Added `React.createElement` API in preparation for React v0.12\n  * `React.createDescriptor` has been deprecated as a result\n\n### JSX\n\n* `<picture>` is now parsed into `React.DOM.picture`\n\n### React Tools\n\n* Update `esprima` and `jstransform` for correctness fixes\n* The `jsx` executable now exposes a `--strip-types` flag which can be used to remove TypeScript-like type annotations\n  * This option is also exposed to `require('react-tools').transform` as `stripTypes`\n\n## 0.11.1 (July 24, 2014)\n\n### React Core\n\n#### Bug Fixes\n* `setState` can be called inside `componentWillMount` in non-DOM environments\n* `SyntheticMouseEvent.getEventModifierState` correctly renamed to `getModifierState`\n* `getModifierState` correctly returns a `boolean`\n* `getModifierState` is now correctly case sensitive\n* Empty Text node used in IE8 `innerHTML` workaround is now removed, fixing rerendering in certain cases\n\n### JSX\n* Fix duplicate variable declaration in JSXTransformer (caused issues in some browsers)\n\n\n## 0.11.0 (July 17, 2014)\n\n### React Core\n\n#### Breaking Changes\n* `getDefaultProps()` is now called once per class and shared across all instances\n* `MyComponent()` now returns a descriptor, not an instance\n* `React.isValidComponent` and `React.PropTypes.component` validate *descriptors*, not component instances\n* Custom `propType` validators should return an `Error` instead of logging directly\n\n#### New Features\n* Rendering to `null`\n* Keyboard events include normalized `e.key` and `e.getModifierState()` properties\n* New normalized `onBeforeInput` event\n* `React.Children.count` has been added as a helper for counting the number of children\n\n#### Bug Fixes\n\n* Re-renders are batched in more cases\n* Events: `e.view` properly normalized\n* Added Support for more HTML attributes (`coords`, `crossOrigin`, `download`, `hrefLang`, `mediaGroup`, `muted`, `scrolling`, `shape`, `srcSet`, `start`, `useMap`)\n* Improved SVG support\n  * Changing `className` on a mounted SVG component now works correctly\n  * Added support for elements `mask` and `tspan`\n  * Added support for attributes `dx`, `dy`, `fillOpacity`, `fontFamily`, `fontSize`, `markerEnd`, `markerMid`, `markerStart`, `opacity`, `patternContentUnits`, `patternUnits`, `preserveAspectRatio`, `strokeDasharray`, `strokeOpacity`\n* CSS property names with vendor prefixes (`Webkit`, `ms`, `Moz`, `O`) are now handled properly\n* Duplicate keys no longer cause a hard error; now a warning is logged (and only one of the children with the same key is shown)\n* `img` event listeners are now unbound properly, preventing the error \"Two valid but unequal nodes with the same `data-reactid`\"\n* Added explicit warning when missing polyfills\n\n### React With Addons\n* PureRenderMixin: a mixin which helps optimize \"pure\" components\n* Perf: a new set of tools to help with performance analysis\n* Update: New `$apply` command to transform values\n* TransitionGroup bug fixes with null elements, Android\n\n### React NPM Module\n* Now includes the pre-built packages under `dist/`.\n* `envify` is properly listed as a dependency instead of a peer dependency\n\n### JSX\n* Added support for namespaces, eg `<Components.Checkbox />`\n* JSXTransformer\n  * Enable the same `harmony` features available in the command line with `<script type=\"text/jsx;harmony=true\">`\n  * Scripts are downloaded in parallel for more speed.

This DOM will not be mountable by React. [Read the docs for `React.renderComponentToStaticMarkup`](https://reactjs.org/docs/top-level-api.html#react.rendercomponenttostaticmarkup)\n* Added support for more attributes:\n  * `srcSet` for `<img>` to specify images at different pixel ratios\n  * `textAnchor` for SVG\n\n#### Bug Fixes\n* Ensure all void elements don’t insert a closing tag into the markup.\n* Ensure `className={false}` behaves consistently\n* Ensure `this.refs` is defined, even if no refs are specified.\n\n### Addons\n\n* `update` function to deal with immutable data. [Read the docs](https://reactjs.org/docs/update.html)\n\n### react-tools\n* Added an option argument to `transform` function. The only option supported is `harmony`, which behaves the same as `jsx --harmony` on the command line. This uses the ES6 transforms from [jstransform](https://github.com/facebook/jstransform).\n\n\n## 0.9.0 (February 20, 2014)\n\n### React Core\n\n#### Breaking Changes\n\n- The lifecycle methods `componentDidMount` and `componentDidUpdate` no longer receive the root node as a parameter; use `this.getDOMNode()` instead\n- Whenever a prop is equal to `undefined`, the default value returned by `getDefaultProps` will now be used instead\n- `React.unmountAndReleaseReactRootNode` was previously deprecated and has now been removed\n- `React.renderComponentToString` is now synchronous and returns the generated HTML string\n- Full-page rendering (that is, rendering the `<html>` tag using React) is now supported only when starting with server-rendered markup\n- On mouse wheel events, `deltaY` is no longer negated\n- When prop types validation fails, a warning is logged instead of an error thrown (with the production build of React, type checks are now skipped for performance)\n- On `input`, `select`, and `textarea` elements, `.getValue()` is no longer supported; use `.getDOMNode().value` instead\n- `this.context` on components is now reserved for internal use by React\n\n#### New Features\n\n- React now never rethrows errors, so stack traces are more accurate and Chrome's purple break-on-error stop sign now works properly\n- Added support for SVG tags `defs`, `linearGradient`, `polygon`, `radialGradient`, `stop`\n- Added support for more attributes:\n  - `crossOrigin` for CORS requests\n  - `download` and `hrefLang` for `<a>` tags\n  - `mediaGroup` and `muted` for `<audio>` and `<video>` tags\n  - `noValidate` and `formNoValidate` for forms\n  - `property` for Open Graph `<meta>` tags\n  - `sandbox`, `seamless`, and `srcDoc` for `<iframe>` tags\n  - `scope` for screen readers\n  - `span` for `<colgroup>` tags\n- Added support for defining `propTypes` in mixins\n- Added `any`, `arrayOf`, `component`, `oneOfType`, `renderable`, `shape` to `React.PropTypes`\n- Added support for `statics` on component spec for static component methods\n- On all events, `.currentTarget` is now properly set\n- On keyboard events, `.key` is now polyfilled in all browsers for special (non-printable) keys\n- On clipboard events, `.clipboardData` is now polyfilled in IE\n- On drag events, `.dragTransfer` is now present\n- Added support for `onMouseOver` and `onMouseOut` in addition to the existing `onMouseEnter` and `onMouseLeave` events\n- Added support for `onLoad` and `onError` on `<img>` elements\n- Added support for `onReset` on `<form>` elements\n- The `autoFocus` attribute is now polyfilled consistently on `input`, `select`, and `textarea`\n\n#### Bug Fixes\n\n- React no longer adds an `__owner__` property to each component's `props` object; passed-in props are now never mutated\n- When nesting top-level components (e.g., calling `React.renderComponent` within `componentDidMount`), events now properly bubble to the parent component\n- Fixed a case where nesting top-level components would throw an error when updating\n- Passing an invalid or misspelled propTypes type now throws an error\n- On mouse enter/leave events, `.target`, `.relatedTarget`, and `.type` are now set properly\n- On composition events, `.data` is now properly normalized in IE9 and IE10\n- CSS property values no longer have `px` appended for the unitless properties `columnCount`, `flex`, `flexGrow`, `flexShrink`, `lineClamp`, `order`, `widows`\n- Fixed a memory leak when unmounting children with a `componentWillUnmount` handler\n- Fixed a memory leak when `renderComponentToString` would store event handlers\n- Fixed an error that could be thrown when removing form elements during a click handler\n- Boolean attributes such as `disabled` are rendered without a value (previously `disabled=\"true\"`, now simply `disabled`)\n- `key` values containing `.` are now supported\n- Shortened `data-reactid` values for performance\n- Components now always remount when the `key` property changes\n- Event handlers are attached to `document` only when necessary, improving performance in some cases\n- Events no longer use `.returnValue` in modern browsers, eliminating a warning in Chrome\n- `scrollLeft` and `scrollTop` are no longer accessed on document.body, eliminating a warning in Chrome\n- General performance fixes, memory optimizations, improvements to warnings and error messages\n\n### React with Addons\n\n- `React.addons.TestUtils` was added to help write unit tests\n- `React.addons.TransitionGroup` was renamed to `React.addons.CSSTransitionGroup`\n- `React.addons.TransitionGroup` was added as a more general animation wrapper\n- `React.addons.cloneWithProps` was added for cloning components and modifying their props\n- Bug fix for adding back nodes during an exit transition for CSSTransitionGroup\n- Bug fix for changing `transitionLeave` in CSSTransitionGroup\n- Performance optimizations for CSSTransitionGroup\n- On checkbox `<input>` elements, `checkedLink` is now supported for two-way binding\n\n### JSX Compiler and react-tools Package\n\n- Whitespace normalization has changed; now space between two tags on the same line will be preserved, while newlines between two tags will be removed\n- The `react-tools` npm package no longer includes the React core libraries; use the `react` package instead.\n- `displayName` is now added in more cases, improving error messages and names in the React Dev Tools\n- Fixed an issue where an invalid token error was thrown after a JSX closing tag\n- `JSXTransformer` now uses source maps automatically in modern browsers\n- `JSXTransformer` error messages now include the filename and problematic line contents when a file fails to parse\n\n## 0.8.0 (December 19, 2013)\n\n### React\n\n* Added support for more attributes:\n  * `rows` & `cols` for `<textarea>`\n  * `defer` & `async` for `<script>`\n  * `loop` for `<audio>` & `<video>`\n  * `autoCorrect` for form fields (a non-standard attribute only supported by mobile WebKit)\n* Improved error messages\n* Fixed Selection events in IE11\n* Added `onContextMenu` events\n\n### React with Addons\n\n* Fixed bugs with TransitionGroup when children were undefined\n* Added support for `onTransition`\n\n### react-tools\n\n* Upgraded `jstransform` and `esprima-fb`\n\n### JSXTransformer\n\n* Added support for use in IE8\n* Upgraded browserify, which reduced file size by ~65KB (16KB gzipped)\n\n\n## 0.5.2, 0.4.2 (December 18, 2013)\n\n### React\n\n* Fixed a potential XSS vulnerability when using user content as a `key`: [CVE-2013-7035](https://groups.google.com/forum/#!topic/reactjs/OIqxlB2aGfU)\n\n\n## 0.5.1 (October 29, 2013)\n\n### React\n\n* Fixed bug with `<input type=\"range\">` and selection events.\n* Fixed bug with selection and focus.\n* Made it possible to unmount components from the document root.\n* Fixed bug for `disabled` attribute handling on non-`<input>` elements.\n\n### React with Addons\n\n* Fixed bug with transition and animation event detection.\n\n\n## 0.5.0 (October 16, 2013)\n\n### React\n\n* Memory usage improvements - reduced allocations in core which will help with GC pauses\n* Performance improvements - in addition to speeding things up, we made some tweaks to stay out of slow path code in V8 and Nitro.\n* Standardized prop -> DOM attribute process. This previously resulting in additional type checking and overhead as well as confusing cases for users. Now we will always convert your value to a string before inserting it into the DOM.\n* Support for Selection events.\n* Support for [Composition events](https://developer.mozilla.org/en-US/docs/Web/API/CompositionEvent).\n* Support for additional DOM properties (`charSet`, `content`, `form`, `httpEquiv`, `rowSpan`, `autoCapitalize`).\n* Support for additional SVG properties (`rx`, `ry`).\n* Support for using `getInitialState` and `getDefaultProps` in mixins.\n* Support mounting into iframes.\n* Bug fixes for controlled form components.\n* Bug fixes for SVG element creation.\n* Added `React.version`.\n* Added `React.isValidClass` - Used to determine if a value is a valid component constructor.\n* Removed `React.autoBind` - This was deprecated in v0.4 and now properly removed.\n* Renamed  `React.unmountAndReleaseReactRootNode` to `React.unmountComponentAtNode`.\n* Began laying down work for refined performance analysis.\n* Better support for server-side rendering - [react-page](https://github.com/facebook/react-page) has helped improve the stability for server-side rendering.\n* Made it possible to use React in environments enforcing a strict [Content Security Policy](https://developer.mozilla.org/en-US/docs/Security/CSP/Introducing_Content_Security_Policy). This also makes it possible to use React to build Chrome extensions.\n\n### React with Addons (New!)\n\n* Introduced a separate build with several \"addons\" which we think can help improve the React experience. We plan to deprecate this in the long-term, instead shipping each as standalone pieces. [Read more in the docs](https://reactjs.org/docs/addons.html).\n\n### JSX\n\n* No longer transform `class` to `className` as part of the transform! This is a breaking change - if you were using `class`, you *must* change this to `className` or your components will be visually broken.\n* Added warnings to the in-browser transformer to make it clear it is not intended for production use.\n* Improved compatibility for Windows\n* Improved support for maintaining line numbers when transforming.\n\n\n## 0.4.1 (July 26, 2013)\n\n### React\n\n* `setState` callbacks are now executed in the scope of your component.\n* `click` events now work on Mobile Safari.\n* Prevent a potential error in event handling if `Object.prototype` is extended.\n* Don't set DOM attributes to the string `\"undefined\"` on update when previously defined.\n* Improved support for `<iframe>` attributes.\n* Added checksums to detect and correct cases where server-side rendering markup mismatches what React expects client-side.\n\n### JSXTransformer\n\n* Improved environment detection so it can be run in a non-browser environment.\n\n\n## 0.4.0 (July 17, 2013)\n\n### React\n\n* Switch from using `id` attribute to `data-reactid` to track DOM nodes. This allows you to integrate with other JS and CSS libraries more easily.\n* Support for more DOM elements and attributes (e.g., `<canvas>`)\n* Improved server-side rendering APIs. `React.renderComponentToString(<component>, callback)` allows you to use React on the server and generate markup which can be sent down to the browser.\n* `prop` improvements: validation and default values. [Read our blog post for details...](https://reactjs.org/blog/2013/07/11/react-v0-4-prop-validation-and-default-values.html)\n* Support for the `key` prop, which allows for finer control over reconciliation. [Read the docs for details...](https://reactjs.org/docs/multiple-components.html)\n* Removed `React.autoBind`. [Read our blog post for details...](https://reactjs.org/blog/2013/07/02/react-v0-4-autobind-by-default.html)\n* Improvements to forms. We've written wrappers around `<input>`, `<textarea>`, `<option>`, and `<select>` in order to standardize many inconsistencies in browser implementations. This includes support for `defaultValue`, and improved implementation of the `onChange` event, and circuit completion. [Read the docs for details...](https://reactjs.org/docs/forms.html)\n* We've implemented an improved synthetic event system that conforms to the W3C spec.\n* Updates to your component are batched now, which may result in a significantly faster re-render of components. `this.setState` now takes an optional callback as it's second parameter. If you were using `onClick={this.setState.bind(this, state)}` previously, you'll want to make sure you add a third parameter so that the event is not treated as the callback.\n\n### JSX\n\n* Support for comment nodes `<div>{/* this is a comment and won't be rendered */}</div>`\n* Children are now transformed directly into arguments instead of being wrapped in an array\n  E.g. `<div><Component1/><Component2/></div>` is transformed into `React.DOM.div(null, Component1(null), Component2(null))`.\n  Previously this would be transformed into `React.DOM.div(null, [Component1(null), Component2(null)])`.\n  If you were using React without JSX previously, your code should still work.\n\n### react-tools\n\n* Fixed a number of bugs when transforming directories\n* No longer re-write `require()`s to be relative unless specified\n\n\n## 0.3.3 (June 20, 2013)\n\n### React\n\n* Allow reusing the same DOM node to render different components. e.g. `React.renderComponent(<div/>, domNode); React.renderComponent(<span/>, domNode);` will work now.\n\n### JSX\n\n* Improved the in-browser transformer so that transformed scripts will execute in the expected scope. The allows components to be defined and used from separate files.\n\n### react-tools\n\n* Upgrade Commoner so `require` statements are no longer relativized when passing through the transformer. This was a feature needed when building React, but doesn't translate well for other consumers of `bin/jsx`.\n* Upgraded our dependencies on Commoner and Recast so they use a different directory for their cache.\n* Freeze our Esprima dependency.\n\n\n## 0.3.2 (May 31, 2013)\n\n### JSX\n\n* Improved compatibility with other coding styles (specifically, multiple assignments with a single `var`).\n\n### react-tools\n\n* Switch from using the browserified build to shipping individual modules. This allows react-tools to be used with [browserify](https://github.com/substack/node-browserify).\n\n\n## 0.3.1 (May 30, 2013)\n\n### react-tools\n\n* Fix bug in packaging resulting in broken module.\n\n\n## 0.3.0 (May 29, 2013)\n\n* Initial public release\n"

Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes. Declarative views make your code more predictable, simpler to understand, and easier to debug.\n* **Component-Based:** Build encapsulated components that manage their own state, then compose them to make complex UIs. Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep the state out of the DOM.\n* **Learn Once, Write Anywhere:** We don't make assumptions about the rest of your technology stack, so you can develop new features in React without rewriting existing code. React can also render on the server using [Node](https://nodejs.org/en) and power mobile apps using [React Native](https://reactnative.dev/).\n\n[Learn how to use React in your project](https://react.dev/learn).\n\n## Installation\n\nReact has been designed for gradual adoption from the start, and **you can use as little or as much React as you need**:\n\n* Use [Quick Start](https://react.dev/learn) to get a taste of React.\n* [Add React to an Existing Project](https://react.dev/learn/add-react-to-an-existing-project) to use as little or as much React as you need.\n* [Create a New React App](https://react.dev/learn/start-a-new-react-project) if you're looking for a powerful JavaScript toolchain.\n\n## Documentation\n\nYou can find the React documentation [on the website](https://react.dev/).\n\nCheck out the [Getting Started](https://react.dev/learn) page for a quick overview.\n\nThe documentation is divided into several sections:\n\n* [Quick Start](https://react.dev/learn)\n* [Tutorial](https://react.dev/learn/tutorial-tic-tac-toe)\n* [Thinking in React](https://react.dev/learn/thinking-in-react)\n* [Installation](https://react.dev/learn/installation)\n* [Describing the UI](https://react.dev/learn/describing-the-ui)\n* [Adding Interactivity](https://react.dev/learn/adding-interactivity)\n* [Managing State](https://react.dev/learn/managing-state)\n* [Advanced Guides](https://react.dev/learn/escape-hatches)\n* [API Reference](https://react.dev/reference/react)\n* [Where to Get Support](https://react.dev/community)\n* [Contributing Guide](https://legacy.reactjs.org/docs/how-to-contribute.html)\n\nYou can improve it by sending pull requests to [this repository](https://github.com/reactjs/react.dev).\n\n## Examples\n\nWe have several examples [on the website](https://react.dev/). Here is the first one to get you started:\n\n```jsx\nimport { createRoot } from 'react-dom/client';\n\nfunction HelloMessage({ name }) {\n  return <div>Hello {name}</div>;\n}\n\nconst root = createRoot(document.getElementById('container'));\nroot.render(<HelloMessage name=\"Taylor\" />);\n```\n\nThis example will render \"Hello Taylor\" into a container on the page.\n\nYou'll notice that we used an HTML-like syntax; [we call it JSX](https://react.dev/learn#writing-markup-with-jsx). JSX is not required to use React, but it makes code more readable, and writing it feels like writing HTML.\n\n## Contributing\n\nThe main purpose of this repository is to continue evolving React core, making it faster and easier to use. Development of React happens in the open on GitHub, and we are grateful to the community for contributing bugfixes and improvements. Read below to learn how you can take part in improving React.\n\n### [Code of Conduct](https://code.fb.com/codeofconduct)\n\nFacebook has adopted a Code of Conduct that we expect project participants to adhere to. Please read [the full text](https://code.fb.com/codeofconduct) so that you can understand what actions will and will not be tolerated.\n\n### [Contributing Guide](https://legacy.reactjs.org/docs/how-to-contribute.html)\n\nRead our [contributing guide](https://legacy.reactjs.org/docs/how-to-contribute.html) to learn about our development process, how to propose bugfixes and improvements, and how to build and test your changes to React.\n\n### [Good First Issues](https://github.com/facebook/react/labels/good%20first%20issue)\n\nTo help you get your feet wet and get you familiar with our contribution process, we have a list of [good first issues](https://github.com/facebook/react/labels/good%20first%20issue) that contain bugs that have a relatively limited scope. This is a great place to get started.\n\n### License\n\nReact is [MIT licensed](./LICENSE).\n"

Use automatically when encountering a failing test case, in order to understand the root cause.\nmodel: opus\ncolor: pink\n---\n\nYou are an expert React Compiler debugging specialist with deep knowledge of compiler internals, intermediate representations, and optimization passes. Your mission is to systematically investigate compiler bugs to identify root causes and provide actionable information for fixes.\n\n## Your Investigation Process\n\n### Step 1: Create Test Fixture\nCreate a new fixture file at `packages/babel-plugin-react-compiler/src/__tests__/fixtures/compiler/<fixture-name>.js` containing the problematic code. Use a descriptive name that reflects the issue (e.g., `bug-optional-chain-in-effect.js`).\n\n### Step 2: Run Debug Compilation\nExecute `yarn snap -d -p <fixture-name>` to compile the fixture with full debug output. This shows the state of the program after each compilation pass. You can also use `yarn snap compile -d <path-to-fixture>`.\n\n### Step 3: Analyze Compilation Results\n\n### Step 3a: If the fixture compiles successfully\n- Compare the output against the user's expected behavior\n- Review each compilation pass output from the `-d` flag\n- Identify the first pass where the output diverges from expected behavior\n- Proceed to binary search simplification\n\n### Step 3b: If the fixture errors\nExecute `yarn snap minimize --update <path-to-fixture>` to remove non-critical aspects of the failing test case. This **updates the fixture in place**.\n\nRe-read the fixture file to see the latest, minimal reproduction of the error.\n\n### Step 4: Iteratively adjust the fixture until it stops erroring\nAfter the previous step the fixture will have all extraneous aspects removed. Try to make further edits to determine the specific feature that is causing the error.\n\nIdeas:\n* Replace immediately-invoked function expressions with labeled blocks\n* Remove statements\n* Simplify calls (remove arguments, replace the call with its lone argument)\n* Simplify control flow statements by picking a single branch. Try using a labeled block with just the selected block\n* Replace optional member/call expressions with non-optional versions\n* Remove items in array/object expressions\n* Remove properties from member expressions\n\nTry to make the minimal possible edit to get the fixture stop erroring.\n\n### Step 5: Compare Debug Outputs\nWith both minimal versions (failing and non-failing):\n- Run `yarn snap -d -p <fixture-name>` on both\n- Compare the debug output pass-by-pass\n- Identify the exact pass where behavior diverges\n- Note specific differences in HIR, effects, or generated code\n\n### Step 6: Investigate Compiler Logic\n- Read the documentation for the problematic pass in `packages/babel-plugin-react-compiler/docs/passes/`\n- Examine the pass implementation in `packages/babel-plugin-react-compiler/src/`\n- Key directories to investigate:\n  - `src/HIR/` - IR definitions and utilities\n  - `src/Inference/` - Effect inference (aliasing, mutation)\n  - `src/Validation/` - Validation passes\n  - `src/Optimization/` - Optimization passes\n  - `src/ReactiveScopes/` - Reactive scope analysis\n- Identify specific code locations that may be handling the pattern incorrectly\n\n## Output Format\n\nProvide a structured investigation report:\n\n```\n## Investigation Summary\n\n### Bug Description\n[Brief description of the issue]\n\n### Minimal Failing Fixture\n```javascript\n// packages/babel-plugin-react-compiler/src/__tests__/fixtures/compiler/<name>.js\n[minimal code that reproduces the error]\n```\n\n### Minimal Non-Failing Fixture\n```javascript\n// The simplest change that makes it work\n[code that compiles correctly]\n```\n\n### Problematic Compiler Pass\n[Name of the pass where the issue occurs]\n\n### Root Cause Analysis\n[Explanation of what the compiler is doing wrong]\n\n### Suspect Code Locations\n- `packages/babel-plugin-react-compiler/src/<path>:<line>:<column>` - [description of what may be incorrect]\n- [additional locations if applicable]\n\n### Suggested Fix Direction\n[Brief suggestion of how the bug might be fixed]\n```\n\n## Key Debugging Tips\n\n1. The debug output (`-d` flag) shows the program state after each pass - use this to pinpoint where things go wrong\n2. Look for `@aliasingEffects=` on FunctionExpressions to understand data flow\n3. Check for `Impure`, `Render`, `Capture` effects on instructions\n4. The pass ordering in `Pipeline.ts` shows when effects are populated vs validated\n5. Todo errors indicate unsupported but known patterns; Invariant errors indicate unexpected states\n\n## Important Reminders\n\n- Always create the fixture file before running tests\n- Use descriptive fixture names that indicate the bug being investigated\n- Keep both failing and non-failing minimal versions for your report\n- Provide specific file:line:column references when identifying suspect code\n- Read the relevant pass documentation before making conclusions about the cause\n"

    "content": "# React Compiler Knowledge Base\n\nThis document contains knowledge about the React Compiler gathered during development sessions. It serves as a reference for understanding the codebase architecture and key concepts.\n\n## Project Structure\n\nWhen modifying the compiler, you MUST read the documentation about that pass in `compiler/packages/babel-plugin-react-compiler/docs/passes/` to learn more about the role of that pass within the compiler.\n\n- `packages/babel-plugin-react-compiler/` - Main compiler package\n  - `src/HIR/` - High-level Intermediate Representation types and utilities\n  - `src/Inference/` - Effect inference passes (aliasing, mutation, etc.)\n  - `src/Validation/` - Validation passes that check for errors\n  - `src/Entrypoint/Pipeline.ts` - Main compilation pipeline with pass ordering\n  - `src/__tests__/fixtures/compiler/` - Test fixtures\n    - `error.todo-*.js` - Unsupported feature, correctly throws Todo error (graceful bailout)\n    - `error.bug-*.js` - Known bug, throws wrong error type or incorrect behavior\n    - `*.expect.md` - Expected output for each fixture\n\n## Running Tests\n\n```bash\n# Run all tests\nyarn snap\n\n# Run tests matching a pattern\n# Example: yarn snap -p 'error.*'\nyarn snap -p <pattern>\n\n# Run a single fixture in debug mode. Use the path relative to the __tests__/fixtures/compiler directory\n# For each step of compilation, outputs the step name and state of the compiled program\n# Example: yarn snap -p simple.js -d\nyarn snap -p <file-basename> -d\n\n# Update fixture outputs (also works with -p)\nyarn snap -u\n```\n\n## Linting\n\n```bash\n# Run lint on the compiler source\nyarn workspace babel-plugin-react-compiler lint\n```\n\n## Formatting\n\n```bash\n# Run prettier on all files (from the react root directory, not compiler/)\nyarn prettier-all\n```\n\n## Compiling Arbitrary Files\n\nUse `yarn snap compile` to compile any file (not just fixtures) with the React Compiler:\n\n```bash\n# Compile a file and see the output\nyarn snap compile <path>\n\n# Compile with debug logging to see the state after each compiler pass\n# This is an alternative to `yarn snap -d -p <pattern>` when you don't have a fixture file yet\nyarn snap compile --debug <path>\n```\n\n## Minimizing Test Cases\n\nUse `yarn snap minimize` to automatically reduce a failing test case to its minimal reproduction:\n\n```bash\n# Minimize a file that causes a compiler error\nyarn snap minimize <path>\n\n# Minimize and update the file in-place with the minimized version\nyarn snap minimize --update <path>\n```\n\n## Version Control\n\nThis repository uses Sapling (`sl`) for version control. Sapling is similar to Mercurial: there is not staging area, but new/deleted files must be explicitly added/removed.\n\n```bash\n# Check status\nsl status\n\n# Add new files, remove deleted files\nsl addremove\n\n# Commit all changes\nsl commit -m \"Your commit message\"\n\n# Commit with multi-line message using heredoc\nsl commit -m \"$(cat <<'EOF'\nSummary line\n\nDetailed description here\nEOF\n)\"\n```\n\n## Key Concepts\n\n### HIR (High-level Intermediate Representation)\n\nThe compiler converts source code to HIR for analysis. Key types in `src/HIR/HIR.ts`:\n\n- **HIRFunction** - A function being compiled\n  - `body.blocks` - Map of BasicBlocks\n  - `context` - Captured variables from outer scope\n  - `params` - Function parameters\n  - `returns` - The function's return place\n  - `aliasingEffects` - Effects that describe the function's behavior when called\n\n- **Instruction** - A single operation\n  - `lvalue` - The place being assigned to\n  - `value` - The instruction kind (CallExpression, FunctionExpression, LoadLocal, etc.)\n  - `effects` - Array of AliasingEffects for this instruction\n\n- **Terminal** - Block terminators (return, branch, etc.)\n  - `effects` - Array of AliasingEffects\n\n- **Place** - A reference to a value\n  - `identifier.id` - Unique IdentifierId\n\n- **Phi nodes** - Join points for values from different control flow paths\n  - Located at `block.phis`\n  - `phi.place` - The result place\n  - `phi.operands` - Map of predecessor block to source place\n\n### AliasingEffects System\n\nEffects describe data flow and operations. Defined in `src/Inference/AliasingEffects.ts`:\n\n**Data Flow Effects:**\n- `Impure` - Marks a place as containing an impure value (e.g., Date.now() result, ref.current)\n- `Capture a -> b` - Value from `a` is captured into `b` (mutable capture)\n- `Alias a -> b` - `b` aliases `a`\n- `ImmutableCapture a -> b` - Immutable capture (like Capture but read-only)\n- `Assign a -> b` - Direct assignment\n- `MaybeAlias a -> b` - Possible aliasing\n- `CreateFrom a -> b` - Created from source\n\n**Mutation Effects:**\n- `Mutate value` - Value is mutated\n- `MutateTransitive value` - Value and transitive captures are mutated\n- `MutateConditionally value` - May mutate\n- `MutateTransitiveConditionally value` - May mutate transitively\n\n**Other Effects:**\n- `Render place` - Place is used in render context (JSX props, component return)\n- `Freeze place` - Place is frozen (made immutable)\n- `Create place` - New value created\n- `CreateFunction` - Function expression created, includes `captures` array\n- `Apply` - Function application with receiver, function, args, and result\n\n### Hook Aliasing Signatures\n\nLocated in `src/HIR/Globals.ts`, hooks can define custom aliasing signatures to control how data flows through them.\n\n**Structure:**\n```typescript\naliasing: {\n  receiver: '@receiver',    // The hook function itself\n  params: ['@param0'],      // Named positional parameters\n  rest: '@rest',            // Rest parameters (or null)\n  returns: '@returns',      // Return value\n  temporaries: [],          // Temporary values during execution\n  effects: [                // Array of effects to apply when hook is called\n    {kind: 'Freeze', value: '@param0', reason: ValueReason.HookCaptured},\n    {kind: 'Assign', from: '@param0', into: '@returns'},\n  ],\n}\n```\n\n**Common patterns:**\n\n1. **RenderHookAliasing** (useState, useContext, useMemo, useCallback):\n   - Freezes arguments (`Freeze @rest`)\n   - Marks arguments as render-time (`Render @rest`)\n   - Creates frozen return value\n   - Aliases arguments to return\n\n2. **EffectHookAliasing** (useEffect, useLayoutEffect, useInsertionEffect):\n   - Freezes function and deps\n   - Creates internal effect object\n   - Captures function and deps into effect\n   - Returns undefined\n\n3. **Event handler hooks** (useEffectEvent):\n   - Freezes callback (`Freeze @fn`)\n   - Aliases input to return (`Assign @fn -> @returns`)\n   - NO Render effect (callback not called during render)\n\n**Example: useEffectEvent**\n```typescript\nconst UseEffectEventHook = addHook(\n  DEFAULT_SHAPES,\n  {\n    positionalParams: [Effect.Freeze],  // Takes one positional param\n    restParam: null,\n    returnType: {kind: 'Function', ...},\n    calleeEffect: Effect.Read,\n    hookKind: 'useEffectEvent',\n    returnValueKind: ValueKind.Frozen,\n    aliasing: {\n      receiver: '@receiver',\n      params: ['@fn'],              // Name for the callback parameter\n      rest: null,\n      returns: '@returns',\n      temporaries: [],\n      effects: [\n        {kind: 'Freeze', value: '@fn', reason: ValueReason.HookCaptured},\n        {kind: 'Assign', from: '@fn', into: '@returns'},\n        // Note: NO Render effect - callback is not called during render\n      ],\n    },\n  },\n  BuiltInUseEffectEventId,\n);\n\n// Add as both names for compatibility\n['useEffectEvent', UseEffectEventHook],\n['experimental_useEffectEvent', UseEffectEventHook],\n```\n\n**Key insight:** If a hook is missing an `aliasing` config, it falls back to `DefaultNonmutatingHook` which includes a `Render` effect on all arguments. This can cause false positives for hooks like `useEffectEvent` whose callbacks are not called during render.\n\n## Feature Flags\n\nFeature flags are configured in `src/HIR/Environment.ts`, for example `enableJsxOutlining`. Test fixtures can override the active feature flags used for that fixture via a comment pragma on the first line of the fixture input, for example:\n\n```javascript\n// enableJsxOutlining @enableNameAnonymousFunctions:false\n\n...code...\n```\n\nWould enable the `enableJsxOutlining` feature and disable the `enableNameAnonymousFunctions` feature.\n\n## Debugging Tips\n\n1. Run `yarn snap -p <fixture>` to see full HIR output with effects\n2. Look for `@aliasingEffects=` on FunctionExpressions\n3. Look for `Impure`, `Render`, `Capture` effects on instructions\n4. Check the pass ordering in Pipeline.ts to understand when effects are populated vs validated\n\n## Error Handling and Fault Tolerance\n\nThe compiler is fault-tolerant: it runs all passes and accumulates errors on the `Environment` rather than throwing on the first error. This lets users see all compilation errors at once.\n\n**Recording errors** — Passes record errors via `env.recordError(diagnostic)`. Errors are accumulated on `Environment.#errors` and checked at the end of the pipeline via `env.hasErrors()` / `env.aggregateErrors()`.\n\n**`tryRecord()` wrapper** — In Pipeline.ts, validation passes are wrapped in `env.tryRecord(() => pass(hir))` which catches thrown `CompilerError`s (non-invariant) and records them. Infrastructure/transformation passes are NOT wrapped in `tryRecord()` because later passes depend on their output being structurally valid.\n\n**Error categories:**\n- `CompilerError.throwTodo()` — Unsupported but known pattern. Graceful bailout. Can be caught by `tryRecord()`.\n- `CompilerError.invariant()` — Truly unexpected/invalid state. Always throws immediately, never caught by `tryRecord()`.\n- Non-`CompilerError` exceptions — Always re-thrown.\n\n**Key files:** `Environment.ts` (`recordError`, `tryRecord`, `hasErrors`, `aggregateErrors`), `Pipeline.ts` (pass orchestration), `Program.ts` (`tryCompileFunction` handles the `Result`).\n\n**Test fixtures:** `__tests__/fixtures/compiler/fault-tolerance/` contains multi-error fixtures verifying all errors are reported.\n"

    "content": "# React Compiler — Goals, Design Principles, and Architecture\n\nThis document describes the goals, design principles, and high-level architecture of React Compiler. See the code for specifics of the data structures and compiler passes.\n\n## Goals\n\nThe idea of React Compiler is to allow developers to use React's familiar declarative, component-based programming model, while ensuring that apps are fast by default. Concretely we seek to achieve the following goals:\n\n* Bound the amount of re-rendering that happens on updates to ensure that apps have predictably fast performance by default.\n* Keep startup time neutral with pre-React Compiler performance. Notably, this means holding code size increases and memoization overhead low enough to not impact startup.\n* Retain React's familiar declarative, component-oriented programming model. i.e, the solution should not fundamentally change how developers think about writing React, and should generally _remove_ concepts (the need to use React.memo(), useMemo(), and useCallback()) rather than introduce new concepts.\n* \"Just work\" on idiomatic React code that follows React's rules (pure render functions, the rules of hooks, etc).\n* Support typical debugging and profiling tools and workflows.\n* Be predictable and understandable enough by React developers — i.e. developers should be able to quickly develop a rough intuition of how React Compiler works.\n* Not require explicit annotations (types or otherwise) for typical product code. We may provide features that allow developers to opt-in to using type information to enable additional optimizations, but the compiler should work well without type information or other annotations.\n\n## Non-Goals\n\nThe following are explicitly *not* goals for React Compiler:\n\n* Provide perfectly optimal re-rendering with zero unnecessary recomputation. This is a non-goal for several reasons:\n  * The runtime overhead of the extra tracking involved can outweigh the cost of recomputation in many cases.\n  * In cases with conditional dependencies it may not be possible to avoid recomputing some/all instructions.\n  * The amount of code may regress startup times, which would conflict with our goal of neutral startup performance.\n* Support code that violates React's rules. React's rules exist to help developers build robust, scalable applications and form a contract that allows us to continue improving React without breaking applications. React Compiler depends on these rules to safely transform code, and violations of rules will therefore break React Compiler's optimizations.\n* Support legacy React features. Notably we will not support class components due to their inherent mutable state being shared across multiple methods with complex lifetimes and data flow.\n* Support 100% of the JavaScript language. In particular, we will not support rarely used features and/or features which are known to be unsafe or which cannot be modeled soundly. For example, nested classes that capture values from their closure are difficult to model accurately because of mutability, and `eval()` is unsafe. We aim to support the vast majority of JavaScript code (and the TypeScript and Flow dialects)\n\n## Design Principles\n\nMany aspects of the design follow naturally from the above goals:\n\n* The compiler output must be high-level code that retains not just the semantics of the input but also is expressed using similar constructs to the input. For example, rather than convert logical expressions (`a ?? b`) into an `if` statement, we retain the high-level form of the logical expression. Rather than convert all looping constructs to a single form, we retain the original form of the loop. This follows from our goals:\n  * High-level code is more compact, and helps reduce the impact of compilation on application size.\n  * High-level constructs that match what the developer wrote are easier to debug.\n* From the above, it then follows that the compiler's internal representation must also be high-level enough to be able to output the original high-level constructs. The internal representation is what we call a High-level Intermediate Representation (HIR) — a name borrowed from Rust Compiler. However, React Compiler's HIR is perhaps even more suited to this name, as it retains high-level information (distinguishing if vs logical vs ternary, or for vs while vs for..of) but also represents code as a control-flow graph with no nesting.\n\n## Architecture\n\nReact Compiler has two primary public interfaces: a Babel plugin for transforming code, and an ESLint plugin for reporting violations of the Rules of React. Internally, both use the same core compiler logic.\n\nThe core of the compiler is largely decoupled from Babel, using its own intermediate representations. The high-level flow is as follows:\n\n- **Babel Plugin**: Determines which functions in a file should be compiled, based on the plugin options and any local opt-in/opt-out directives. For each component or hook to be compiled, the plugin calls the compiler, passing in the original function and getting back a new AST node which will replace the original.\n- **Lowering** (BuildHIR): The first step of the compiler is to convert the Babel AST into React Compiler's primary intermediate representation, HIR (High-level Intermediate Representation). This phase is primarily based on the AST itself, but currently leans on Babel to resolve identifiers. The HIR preserves the precise order-of-evaluation semantics of JavaScript, resolves break/continue to their jump points, etc. The resulting HIR forms a control-flow graph of basic blocks, each of which contains zero or more consecutive instructions followed by a terminal. The basic blocks are stored in reverse postorder, such that forward iteration of the blocks allows predecessors to be visited before successors _unless_ there is a \"back edge\" (i.e. a loop).\n- **SSA Conversion** (EnterSSA): The HIR is converted to HIR form, such that all Identifiers in the HIR are updated to an SSA-based identifier.\n- Validation: We run various validation passes to check that the input is valid React, i.e. that it does not break the rules. This includes looking for conditional hook calls, unconditional setState calls, etc.\n- **Optimization**: Various passes such as dead code elimination and constant propagation can generally improve performance and reduce the amount of instructions to be optimized later.\n- **Type Inference** (InferTypes): We run a conservative type inference pass to identify certain key types of data that may appear in the program that are relevant for further analysis, such as which values are hooks, primitives, etc. \n- **Inferring Reactive Scopes**: Several passes are involved in determining groups of values that are created/mutated together and the set of instructions involved in creating/mutating those values. We call these groups \"reactive scopes\", and each can have one or more declarations (or occasionally a reassignment).\n- **Constructing/Optimizing Reactive Scopes**: Once the compiler determines the set of reactive scopes, it then transforms the program to make these scopes explicit in the HIR. The code is later converted to a ReactiveFunction, which is a hybrid of the HIR and an AST. Scopes are further pruned and transformed. For example, the compiler cannot make hook calls conditional, so any reactive scopes that contain a hook call must be pruned. If two consecutive scopes will always invalidate together, we attempt to merge them to reduce overhead, etc.\n- **Codegen**: Finally, the ReactiveFunction hybrid HIR/AST is converted back to a raw Babel AST node, and returned to the Babel plugin.\n- **Babel Plugin**: The Babel plugin replaces the original node with the new version.\n\nThe ESLint plugin works similarly. For now, it effectively invokes the Babel plugin on the code and reports back a subset of the errors. The compiler can report a variety of errors, including that the code is simply invalid JavaScript, but the ESLint plugin filters to only show the React-specific errors.\n"

    "content": "# lower (BuildHIR)\n\n## File\n`src/HIR/BuildHIR.ts`\n\n## Purpose\nConverts a Babel AST function node into a High-level Intermediate Representation (HIR), which represents code as a control-flow graph (CFG) with basic blocks, instructions, and terminals. This is the first major transformation pass in the React Compiler pipeline, enabling precise expression-level memoization analysis.\n\n## Input Invariants\n- Input must be a valid Babel `NodePath<t.Function>` (FunctionDeclaration, FunctionExpression, or ArrowFunctionExpression)\n- The function must be a component or hook (determined by the environment)\n- Babel scope analysis must be available for binding resolution\n- An `Environment` instance must be provided with compiler configuration\n- Optional `bindings` map for nested function lowering (recursive calls)\n- Optional `capturedRefs` map for context variables captured from outer scope\n\n## Output Guarantees\n- Returns `Result<HIRFunction, CompilerError>` - either a successfully lowered function or compilation errors\n- The HIR function contains:\n  - A complete CFG with basic blocks (`body.blocks: Map<BlockId, BasicBlock>`)\n  - Each block has an array of instructions and exactly one terminal\n  - All control flow is explicit (if/else, loops, switch, logical operators, ternary)\n  - Parameters are converted to `Place` or `SpreadPattern`\n  - Context captures are tracked in `context` array\n  - Function metadata (id, async, generator, directives)\n- All identifiers get unique `IdentifierId` values\n- Instructions have placeholder instruction IDs (set to 0, assigned later)\n- Effects are null (populated by later inference passes)\n\n## Algorithm\nThe lowering algorithm uses a recursive descent pattern with a `HIRBuilder` helper class:\n\n1. **Initialization**: Create an `HIRBuilder` with environment and optional bindings. Process captured context variables.\n\n2. **Parameter Processing**: For each function parameter:\n   - Simple identifiers: resolve binding and create Place\n   - Patterns (object/array): create temporary Place, then emit destructuring assignments\n   - Rest elements: wrap in SpreadPattern\n   - Unsupported: emit Todo error\n\n3. **Body Processing**:\n   - Arrow function expressions: lower body expression to temporary, emit implicit return\n   - Block statements: recursively lower each statement\n\n4. **Statement Lowering** (`lowerStatement`): Handle each statement type:\n   - **Control flow**: Create separate basic blocks for branches, loops connect back to conditional blocks\n   - **Variable declarations**: Create `DeclareLocal`/`DeclareContext` or `StoreLocal`/`StoreContext` instructions\n   - **Expressions**: Lower to temporary and discard result\n   - **Hoisting**: Detect forward references and emit `DeclareContext` for hoisted identifiers\n\n5. **Expression Lowering** (`lowerExpression`): Convert expressions to `InstructionValue`:\n   - **Identifiers**: Create `LoadLocal`, `LoadContext`, or `LoadGlobal` based on binding\n   - **Literals**: Create `Primitive` values\n   - **Operators**: Create `BinaryExpression`, `UnaryExpression` etc.\n   - **Calls**: Distinguish `CallExpression` vs `MethodCall` (member expression callee)\n   - **Control flow expressions**: Create separate value blocks for branches (ternary, logical, optional chaining)\n   - **JSX**: Lower to `JsxExpression` with lowered tag, props, and children\n\n6. **Block Management**: The builder maintains:\n   - A current work-in-progress block accumulating instructions\n   - Completed blocks map\n   - Scope stack for break/continue resolution\n   - Exception handler stack for try/catch\n\n7. **Termination**: Add implicit void return at end if no explicit return\n\n## Key Data Structures\n\n### HIRBuilder (from HIRBuilder.ts)\n- `#current: WipBlock` - Work-in-progress block being populated\n- `#completed: Map<BlockId, BasicBlock>` - Finished blocks\n- `#scopes: Array<Scope>` - Stack for break/continue target resolution (LoopScope, LabelScope, SwitchScope)\n- `#exceptionHandlerStack: Array<BlockId>` - Stack of catch handlers for try/catch\n- `#bindings: Bindings` - Map of variable names to their identifiers\n- `#context: Map<t.Identifier, SourceLocation>` - Captured context variables\n- Methods: `push()`, `reserve()`, `enter()`, `terminate()`, `terminateWithContinuation()`\n\n### Core HIR Types\n- **BasicBlock**: Contains `instructions: Array<Instruction>`, `terminal: Terminal`, `preds: Set<BlockId>`, `phis: Set<Phi>`, `kind: BlockKind`\n- **Instruction**: Contains `id`, `lvalue` (Place), `value` (InstructionValue), `effects` (null initially), `loc`\n- **Terminal**: Block terminator - `if`, `branch`, `goto`, `return`, `throw`, `for`, `while`, `switch`, `ternary`, `logical`, etc.\n- **Place**: Reference to a value - `{kind: 'Identifier', identifier, effect, reactive, loc}`\n- **InstructionValue**: The operation - `LoadLocal`, `StoreLocal`, `CallExpression`, `BinaryExpression`, `FunctionExpression`, etc.\n\n### Block Kinds\n- `block` - Regular sequential block\n- `loop` - Loop header/test block\n- `value` - Block that produces a value (ternary/logical branches)\n- `sequence` - Sequence expression block\n- `catch` - Exception handler block\n\n## Edge Cases\n\n1. **Hoisting**: Forward references to `let`/`const`/`function` declarations emit `DeclareContext` before the reference, enabling correct temporal dead zone handling\n\n2. **Context Variables**: Variables captured by nested functions use `LoadContext`/`StoreContext` instead of `LoadLocal`/`StoreLocal`\n\n3. **For-of/For-in Loops**: Synthesize iterator instructions (`GetIterator`, `IteratorNext`, `NextPropertyOf`)\n\n4. **Optional Chaining**: Creates nested `OptionalTerminal` structures with short-circuit branches\n\n5. **Logical Expressions**: Create branching structures where left side stores to temporary, right side only evaluated if needed\n\n6. **Try/Catch**: Adds `MaybeThrowTerminal` after each instruction in try block, modeling potential control flow to handler\n\n7. **JSX in fbt**: Tracks `fbtDepth` counter to handle whitespace differently in fbt/fbs tags\n\n8. **Unsupported Syntax**: `var` declarations, `with` statements, inline `class` declarations, `eval` - emit appropriate errors\n\n## TODOs\n- `returnTypeAnnotation: null, // TODO: extract the actual return type node if present`\n- `TODO(gsn): In the future, we could only pass in the context identifiers that are actually used by this function and its nested functions`\n- Multiple `// TODO remove type cast` in destructuring pattern handling\n- `// TODO: should JSX namespaced names be handled here as well?`\n\n## Example\nInput JavaScript:\n```javascript\nexport default function foo(x, y) {\n  if (x) {\n    return foo(false, y);\n  }\n  return [y * 10];\n}\n```\n\nOutput HIR (simplified):\n```\nfoo(<unknown> x$0, <unknown> y$1): <unknown> $12\nbb0 (block):\n  [1] <unknown> $6 = LoadLocal <unknown> x$0\n  [2] If (<unknown> $6) then:bb2 else:bb1 fallthrough=bb1\n\nbb2 (block):\n  predecessor blocks: bb0\n  [3] <unknown> $2 = LoadGlobal(module) foo\n  [4] <unknown> $3 = false\n  [5] <unknown> $4 = LoadLocal <unknown> y$1\n  [6] <unknown> $5 = Call <unknown> $2(<unknown> $3, <unknown> $4)\n  [7] Return Explicit <unknown> $5\n\nbb1 (block):\n  predecessor blocks: bb0\n  [8] <unknown> $7 = LoadLocal <unknown> y$1\n  [9] <unknown> $8 = 10\n  [10] <unknown> $9 = Binary <unknown> $7 * <unknown> $8\n  [11] <unknown> $10 = Array [<unknown> $9]\n  [12] Return Explicit <unknown> $10\n```\n\nKey observations:\n- The function has 3 basic blocks: entry (bb0), consequent (bb2), alternate/fallthrough (bb1)\n- The if statement creates an `IfTerminal` at the end of bb0\n- Each branch ends with its own `ReturnTerminal`\n- All values are stored in temporaries (`$N`) or named identifiers (`x$0`, `y$1`)\n- Instructions have sequential IDs within blocks\n- Types and effects are `<unknown>` at this stage (populated by later passes)\n"

    "content": "# enterSSA\n\n## File\n`src/SSA/EnterSSA.ts`\n\n## Purpose\nConverts the HIR from a non-SSA form (where variables can be reassigned) into Static Single Assignment (SSA) form, where each variable is defined exactly once and phi nodes are inserted at control flow join points to merge values from different paths.\n\n## Input Invariants\n- The HIR must have blocks in reverse postorder (predecessors visited before successors, except for back-edges)\n- Block predecessor information (`block.preds`) must be populated correctly\n- The function's `context` array must be empty for the root function (outer function declarations)\n- Identifiers may be reused across multiple definitions/assignments (non-SSA form)\n\n## Output Guarantees\n- Each identifier has a unique `IdentifierId` - no identifier is defined more than once\n- All operand references use the SSA-renamed identifiers\n- Phi nodes are inserted at join points where values from different control flow paths converge\n- Function parameters are SSA-renamed\n- Nested functions (FunctionExpression, ObjectMethod) are recursively converted to SSA form\n- Context variables (captured from outer scopes) are handled specially and not redefined\n\n## Algorithm\nThe pass uses the Braun et al. algorithm (\"Simple and Efficient Construction of Static Single Assignment Form\") with adaptations for handling loops and nested functions.\n\n### Key Steps:\n1. **Block Traversal**: Iterate through blocks in order (assumed reverse postorder from previous passes)\n2. **Definition Tracking**: Maintain a per-block `defs` map from original identifiers to their SSA-renamed versions\n3. **Renaming**:\n   - When a value is **defined** (lvalue), create a new SSA identifier with fresh `IdentifierId`\n   - When a value is **used** (operand), look up the current SSA identifier via `getIdAt`\n4. **Phi Node Insertion**: When looking up an identifier at a block with multiple predecessors:\n   - If all predecessors have been visited, create a phi node collecting values from each predecessor\n   - If some predecessors are unvisited (back-edge/loop), create an \"incomplete phi\" that will be fixed later\n5. **Incomplete Phi Resolution**: When all predecessors of a block are finally visited, fix any incomplete phi nodes by populating their operands\n6. **Nested Function Handling**: Recursively apply SSA transformation to nested functions, temporarily adding a fake predecessor edge to enable identifier lookup from the enclosing scope\n\n### Phi Node Placement Logic (`getIdAt`):\n- If the identifier is defined locally in the current block, return it\n- If at entry block with no predecessors and not found, mark as unknown (global)\n- If some predecessors are unvisited (loop), create incomplete phi\n- If exactly one predecessor, recursively look up in that predecessor\n- If multiple predecessors, create phi node with operands from all predecessors\n\n## Key Data Structures\n- **SSABuilder**: Main class managing the transformation\n  - `#states: Map<BasicBlock, State>` - Per-block state (defs map and incomplete phis)\n  - `unsealedPreds: Map<BasicBlock, number>` - Count of unvisited predecessors per block\n  - `#unknown: Set<Identifier>` - Identifiers assumed to be globals\n  - `#context: Set<Identifier>` - Context variables that should not be redefined\n- **State**: Per-block state containing:\n  - `defs: Map<Identifier, Identifier>` - Maps original identifiers to SSA-renamed versions\n  - `incompletePhis: Array<IncompletePhi>` - Phi nodes waiting for predecessor values\n- **IncompletePhi**: Tracks a phi node created before all predecessors were visited\n  - `oldPlace: Place` - Original place being phi'd\n  - `newPlace: Place` - SSA-renamed phi result place\n- **Phi**: The actual phi node in the HIR\n  - `place: Place` - The result of the phi\n  - `operands: Map<BlockId, Place>` - Maps predecessor block to the place providing the value\n\n## Edge Cases\n- **Loops (back-edges)**: When a variable is used in a loop header before the loop body assigns it, an incomplete phi is created and later fixed when the loop body block is visited\n- **Globals**: If an identifier is used but never defined (reaching the entry block without a definition), it's assumed to be a global and not renamed\n- **Context variables**: Variables captured from an outer function scope are tracked specially and not redefined when reassigned\n- **Nested functions**: Function expressions and object methods are processed recursively with a temporary predecessor edge linking them to the enclosing block\n\n## TODOs\n- `[hoisting] EnterSSA: Expected identifier to be defined before being used` - Handles cases where hoisting causes an identifier to be used before definition (throws a Todo error for graceful bailout)\n\n## Example\n\n### Input (simple reassignment with control flow):\n```javascript\nfunction foo() {\n  let y = 2;\n  if (y > 1) {\n    y = 1;\n  } else {\n    y = 2;\n  }\n  let x = y;\n}\n```\n\n### Before SSA (HIR):\n```\nbb0 (block):\n  [1] $0 = 2\n  [2] $2 = StoreLocal Let y$1 = $0\n  [3] $7 = LoadLocal y$1\n  [4] $8 = 1\n  [5] $9 = Binary $7 > $8\n  [6] If ($9) then:bb2 else:bb3 fallthrough=bb1\n\nbb2 (block):\n  predecessor blocks: bb0\n  [7] $3 = 1\n  [8] $4 = StoreLocal Reassign y$1 = $3  // Same y$1 reassigned\n  [9] Goto bb1\n\nbb3 (block):\n  predecessor blocks: bb0\n  [10] $5 = 2\n  [11] $6 = StoreLocal Reassign y$1 = $5  // Same y$1 reassigned\n  [12] Goto bb1\n\nbb1 (block):\n  predecessor blocks: bb2 bb3\n  [13] $10 = LoadLocal y$1                // Which y$1?\n  [14] $12 = StoreLocal Let x$11 = $10\n```\n\n### After SSA:\n```\nbb0 (block):\n  [1] $15 = 2\n  [2] $17 = StoreLocal Let y$16 = $15    // y$16: initial definition\n  [3] $18 = LoadLocal y$16\n  [4] $19 = 1\n  [5] $20 = Binary $18 > $19\n  [6] If ($20) then:bb2 else:bb3 fallthrough=bb1\n\nbb2 (block):\n  predecessor blocks: bb0\n  [7] $21 = 1\n  [8] $23 = StoreLocal Reassign y$22 = $21  // y$22: new SSA name\n  [9] Goto bb1\n\nbb3 (block):\n  predecessor blocks: bb0\n  [10] $24 = 2\n  [11] $26 = StoreLocal Reassign y$25 = $24  // y$25: new SSA name\n  [12] Goto bb1\n\nbb1 (block):\n  predecessor blocks: bb2 bb3\n  y$27: phi(bb2: y$22, bb3: y$25)           // PHI NODE: merges y$22 and y$25\n  [13] $28 = LoadLocal y$27                  // Uses phi result\n  [14] $30 = StoreLocal Let x$29 = $28\n```\n\n### Loop Example (while loop with back-edge):\n```javascript\nfunction foo() {\n  let x = 1;\n  while (x < 10) {\n    x = x + 1;\n  }\n  return x;\n}\n```\n\n### After SSA:\n```\nbb0 (block):\n  [1] $13 = 1\n  [2] $15 = StoreLocal Let x$14 = $13    // x$14: initial definition\n  [3] While test=bb1 loop=bb3 fallthrough=bb2\n\nbb1 (loop):\n  predecessor blocks: bb0 bb3\n  x$16: phi(bb0: x$14, bb3: x$23)        // PHI merges initial and loop-updated values\n  [4] $17 = LoadLocal x$16\n  [5] $18 = 10\n  [6] $19 = Binary $17 < $18\n  [7] Branch ($19) then:bb3 else:bb2\n\nbb3 (block):\n  predecessor blocks: bb1\n  [8] $20 = LoadLocal x$16               // Uses phi result\n  [9] $21 = 1\n  [10] $22 = Binary $20 + $21\n  [11] $24 = StoreLocal Reassign x$23 = $22  // x$23: new SSA name in loop body\n  [12] Goto(Continue) bb1\n\nbb2 (block):\n  predecessor blocks: bb1\n  [13] $25 = LoadLocal x$16              // Uses phi result\n  [14] Return Explicit $25\n```\n\nThe phi node at `bb1` (the loop header) is initially created as an \"incomplete phi\" when first visited because `bb3` (the loop body) hasn't been visited yet.

    "content": "# eliminateRedundantPhi\n\n## File\n`src/SSA/EliminateRedundantPhi.ts`\n\n## Purpose\nEliminates phi nodes whose operands are trivially the same, replacing all usages of the phi's output identifier with the single source identifier. This simplifies the HIR by removing unnecessary join points that do not actually merge distinct values.\n\n## Input Invariants\n- The function must be in SSA form (i.e., `enterSSA` has already run)\n- Blocks are in reverse postorder (guaranteed by the HIR structure)\n- Phi nodes exist at the start of blocks where control flow merges\n\n## Output Guarantees\n- All redundant phi nodes are removed from the HIR\n- All references to eliminated phi identifiers are rewritten to the source identifier\n- Non-redundant phi nodes (those merging two or more distinct values) are preserved\n- Nested function expressions (FunctionExpression, ObjectMethod) also have their redundant phis eliminated and contexts rewritten\n\n## Algorithm\nA phi node is considered redundant when:\n1. **All operands are the same identifier**: e.g., `x2 = phi(x1, x1, x1)` - the phi is replaced with `x1`\n2. **All operands are either the same identifier OR the phi's output**: e.g., `x2 = phi(x1, x2, x1, x2)` - this handles loop back-edges where the phi references itself\n\nThe algorithm works as follows:\n1. Visit blocks in reverse postorder, building a rewrite table (`Map<Identifier, Identifier>`)\n2. For each phi node in a block:\n   - First rewrite operands using any existing rewrites (to handle cascading eliminations)\n   - Check if all operands (excluding self-references) point to the same identifier\n   - If so, add a mapping from the phi's output to that identifier and delete the phi\n3. After processing phis, rewrite all instruction lvalues, operands, and terminal operands\n4. For nested functions, recursively call `eliminateRedundantPhi` with shared rewrites\n5. If the CFG has back-edges (loops) and new rewrites were added, repeat the entire process\n\nThe loop termination condition `rewrites.size > size && hasBackEdge` ensures:\n- Without loops: completes in a single pass (reverse postorder guarantees forward propagation)\n- With loops: repeats until no new rewrites are found (fixpoint)\n\n## Key Data Structures\n- **`Phi`** (from `src/HIR/HIR.ts`): Represents a phi node with:\n  - `place: Place` - the output identifier\n  - `operands: Map<BlockId, Place>` - maps predecessor block IDs to source places\n- **`rewrites: Map<Identifier, Identifier>`**: Maps eliminated phi outputs to their replacement identifier\n- **`visited: Set<BlockId>`**: Tracks visited blocks to detect back-edges (loops)\n\n## Edge Cases\n- **Loop back-edges**: When a block has a predecessor that hasn't been visited yet (in reverse postorder), that predecessor is a back-edge. The algorithm handles self-referential phis like `x2 = phi(x1, x2)` by ignoring operands equal to the phi's output.\n- **Cascading eliminations**: When one phi's output is used in another phi's operands, the algorithm rewrites operands before checking redundancy, enabling transitive elimination in a single pass (for non-loop cases).\n- **Nested functions**: FunctionExpression and ObjectMethod values contain nested HIR that may have their own phis. The algorithm recursively processes these with a shared rewrite table, ensuring context captures are also rewritten.\n- **Empty phi check**: The algorithm includes an invariant check that phi operands are never empty (which would be invalid HIR).\n\n## TODOs\n(None found in the source code)\n\n## Example\n\nConsider this fixture from `rewrite-phis-in-lambda-capture-context.js`:\n\n```javascript\nfunction Component() {\n  const x = 4;\n  const get4 = () => {\n    while (bar()) {\n      if (baz) { bar(); }\n    }\n    return () => x;\n  };\n  return get4;\n}\n```\n\n**After SSA pass**, the inner function has redundant phis due to the loop:\n\n```\nbb2 (loop):\n  predecessor blocks: bb1 bb5\n  x$29: phi(bb1: x$21, bb5: x$30)  // Loop header phi\n  ...\nbb5 (block):\n  predecessor blocks: bb6 bb4\n  x$30: phi(bb6: x$29, bb4: x$29)  // Redundant: both operands are x$29\n  ...\n```\n\n**After EliminateRedundantPhi**:\n- `x$30 = phi(x$29, x$29)` is eliminated because both operands are `x$29`\n- `x$29 = phi(x$21, x$30)` becomes `x$29 = phi(x$21, x$29)` after rewriting, which is also redundant (one operand is the phi itself, the other is `x$21`)\n- Both phis are eliminated, and all uses of `x$29` and `x$30` are rewritten to `x$21`\n\nThe result: the context capture `@context[x$29]` becomes `@context[x$21]`, correctly propagating that `x` is never modified inside the loop.\n"

This pass annotates identifiers with concrete types (Primitive, Object, Function) based on the operations performed on them and the types of globals/hooks they interact with.\n\n## Input Invariants\n- The HIR must be in SSA form (the pass runs after `enterSSA` and `eliminateRedundantPhi`)\n- Constant propagation has already run\n- Global declarations and hook shapes are available via the Environment\n\n## Output Guarantees\n- All identifier types are resolved from type variables (`Type`) to concrete types where possible\n- Phi nodes have their operand types unified to produce a single result type\n- Function return types are inferred from the unified types of all return statements\n- Property accesses on known objects/hooks resolve to the declared property types\n- Component props parameters are typed as `TObject<BuiltInProps>`\n- Component ref parameters are typed as `TObject<BuiltInUseRefId>`\n\n## Algorithm\nThe pass uses a classic constraint-based type inference approach with three phases:\n\n1. **Constraint Generation (`generate`)**: Traverses all instructions and generates type equations:\n   - Primitives, literals, unary/binary operations -> `Primitive` type\n   - Hook/function calls -> Function type with fresh return type variable\n   - Property loads -> `Property` type that defers to object shape lookup\n   - Destructuring -> Property types for each extracted element\n   - Phi nodes -> `Phi` type with all operand types as candidates\n   - JSX -> `Object<BuiltInJsx>`\n   - Arrays -> `Object<BuiltInArray>`\n   - Objects -> `Object<BuiltInObject>`\n\n2. **Unification (`Unifier.unify`)**: Solves constraints by unifying type equations:\n   - Type variables are bound to concrete types via substitution\n   - Property types are resolved by looking up the object's shape\n   - Phi types are resolved by finding a common type among operands (or falling back to `Phi` if incompatible)\n   - Function types are unified by unifying their return types\n   - Occurs check prevents infinite types (cycles in type references)\n\n3. **Application (`apply`)**: Applies the computed substitutions to all identifiers in the HIR, replacing type variables with their resolved types.\n\n## Key Data Structures\n- **TypeVar** (`kind: 'Type'`): A type variable with a unique TypeId, used for unknowns\n- **Unifier**: Maintains a substitution map from TypeId to Type, with methods for unification and cycle detection\n- **TypeEquation**: A pair of types that should be equal, used as constraints\n- **PhiType** (`kind: 'Phi'`): Represents the join of multiple types from control flow merge points\n- **PropType** (`kind: 'Property'`): Deferred property lookup that resolves based on object shape\n- **FunctionType** (`kind: 'Function'`): Callable type with optional shapeId and return type\n- **ObjectType** (`kind: 'Object'`): Object with optional shapeId for shape lookup\n\n## Edge Cases\n\n### Phi Type Resolution\nWhen phi operands have incompatible types, the pass attempts to find a union:\n- `Union(Primitive | MixedReadonly) = MixedReadonly`\n- `Union(Array | MixedReadonly) = Array`\n- If no union is possible, the type remains as `Phi`\n\n### Ref-like Name Inference\nWhen `enableTreatRefLikeIdentifiersAsRefs` is enabled, property access on variables matching the pattern `/^(?:[a-zA-Z$_][a-zA-Z$_0-9]*)Ref$|^ref$/` with property name `current` infers:\n- Object type as `TObject<BuiltInUseRefId>`\n- Property type as `TObject<BuiltInRefValue>`\n\n### Cycle Detection\nThe `occursCheck` method prevents infinite types by detecting when a type variable appears in its own substitution. When a cycle is detected, `tryResolveType` removes the cyclic reference from Phi operands.\n\n### Context Variables\n- `DeclareContext` and `LoadContext` generate no type equations (intentionally untyped)\n- `StoreContext` with `Const` kind does propagate the rvalue type to enable ref inference through context variables\n\n## TODOs\n1. **Hook vs Function type ambiguity**:\n   > \"TODO: callee could be a hook or a function, so this type equation isn't correct. We should change Hook to a subtype of Function or change unifier logic.\"\n\n2. **PropertyStore rvalue inference**:\n   > \"TODO: consider using the rvalue type here\" - Currently uses a dummy type for PropertyStore to avoid inferring rvalue types from lvalue assignments.\n\n## Example\n\n**Input (infer-phi-primitive.js):**\n```javascript\nfunction foo(a, b) {\n  let x;\n  if (a) {\n    x = 1;\n  } else {\n    x = 2;\n  }\n  let y = x;\n  return y;\n}\n```\n\n**Before InferTypes (SSA form):**\n```\n<unknown> x$26: phi(bb2: <unknown> x$21, bb3: <unknown> x$24)\n[10] <unknown> $27 = LoadLocal <unknown> x$26\n[11] <unknown> $29 = StoreLocal Let <unknown> y$28 = <unknown> $27\n```\n\n**After InferTypes:**\n```\n<unknown> x$26:TPrimitive: phi(bb2: <unknown> x$21:TPrimitive, bb3: <unknown> x$24:TPrimitive)\n[10] <unknown> $27:TPrimitive = LoadLocal <unknown> x$26:TPrimitive\n[11] <unknown> $29:TPrimitive = StoreLocal Let <unknown> y$28:TPrimitive = <unknown> $27:TPrimitive\n```\n\nThe pass infers that:\n- Literals `1` and `2` are `TPrimitive`\n- The phi of two primitives is `TPrimitive`\n- Variables `x` and `y` are `TPrimitive`\n- The function return type is `TPrimitive`\n\n**Hook type inference example (useState):**\n```javascript\nconst [x, setX] = useState(initialValue);\n```\n\nAfter InferTypes:\n- `useState` -> `TFunction<BuiltInUseState>:TObject<BuiltInUseState>`\n- Return value `$27` -> `TObject<BuiltInUseState>`\n- Destructured `setX` -> `TFunction<BuiltInSetState>:TPrimitive`\n"

    "content": "# inferMutationAliasingEffects\n\n## File\n`src/Inference/InferMutationAliasingEffects.ts`\n\n## Purpose\nInfers the mutation and aliasing effects for all instructions and terminals in the HIR, making the effects of built-in instructions/functions as well as user-defined functions explicit. These effects form the basis for subsequent analysis to determine the mutable range of each value in the program and for validation against invalid code patterns like mutating frozen values.\n\n## Input Invariants\n- HIR must be in SSA form (run after SSA pass)\n- Types must be inferred (run after InferTypes pass)\n- Functions must be analyzed (run after AnalyseFunctions pass) - this provides `aliasingEffects` on FunctionExpressions\n- Each instruction must have an lvalue (destination place)\n\n## Output Guarantees\n- Every instruction has an `effects` array (or null if no effects) containing `AliasingEffect` objects\n- Terminals that affect data flow (return, try/catch) have their `effects` populated\n- Each instruction's lvalue is guaranteed to be defined in the inference state after visiting\n- Effects describe: creation of values, data flow (Assign, Alias, Capture), mutations (Mutate, MutateTransitive), freezing, and errors (MutateFrozen, MutateGlobal, Impure)\n\n## Algorithm\nThe pass uses abstract interpretation with the following key phases:\n\n1. **Initialization**:\n   - Create initial `InferenceState` mapping identifiers to abstract values\n   - Initialize context variables as `ValueKind.Context`\n   - Initialize parameters as `ValueKind.Frozen` (for top-level components/hooks) or `ValueKind.Mutable` (for function expressions)\n\n2. **Two-Phase Effect Processing**:\n   - **Phase 1 - Signature Computation**: For each instruction, compute a \"candidate signature\" based purely on instruction semantics and types (cached per instruction via `computeSignatureForInstruction`)\n   - **Phase 2 - Effect Application**: Apply the signature to the current abstract state via `applySignature`, which refines effects based on the actual runtime kinds of values\n\n3. **Fixed-Point Iteration**:\n   - Process blocks in a worklist, queuing successors after each block\n   - Merge states at control flow join points using lattice operations\n   - Iterate until no changes occur (max 100 iterations as safety limit)\n   - Phi nodes are handled by unioning the abstract values from all predecessors\n\n4. **Effect Refinement** (in `applyEffect`):\n   - `MutateConditionally` effects are dropped if value is not mutable\n   - `Capture` effects are downgraded to `ImmutableCapture` if source is frozen\n   - `Mutate` on frozen values becomes `MutateFrozen` error\n   - `Assign` from primitives/globals creates new values rather than aliasing\n\n## Key Data Structures\n\n### InferenceState\nMaintains two maps:\n- `#values: Map<InstructionValue, AbstractValue>` - Maps allocation sites to their abstract kind\n- `#variables: Map<IdentifierId, Set<InstructionValue>>` - Maps identifiers to the set of values they may point to (set to handle phi joins)\n\n### AbstractValue\n```typescript\ntype AbstractValue = {\n  kind: ValueKind;\n  reason: ReadonlySet<ValueReason>;\n};\n```\n\n### ValueKind (lattice)\n```\nMaybeFrozen    <- top (unknown if frozen or mutable)\n    |\n  Frozen       <- immutable, cannot be mutated\n  Mutable      <- can be mutated locally\n  Context      <- mutable box (context variables)\n    |\n  Global       <- global value\n  Primitive    <- copy-on-write semantics\n```\n\nThe `mergeValueKinds` function implements the lattice join:\n- `Frozen | Mutable -> MaybeFrozen`\n- `Context | Mutable -> Context`\n- `Context | Frozen -> MaybeFrozen`\n\n### AliasingEffect Types\nKey effect kinds handled:\n- **Create**: Creates a new value at a place\n- **Assign**: Direct assignment (pointer copy)\n- **Alias**: Mutation of destination implies mutation of source\n- **Capture**: Information flow (MutateTransitive propagates through)\n- **MaybeAlias**: Possible aliasing for unknown function returns\n- **Mutate/MutateTransitive**: Direct/transitive mutation\n- **MutateConditionally/MutateTransitiveConditionally**: Conditional versions\n- **Freeze**: Marks value as immutable\n- **Apply**: Function call with complex data flow\n\n## Edge Cases\n\n1. **Spread Destructuring from Props**: The `findNonMutatedDestructureSpreads` pre-pass identifies spread patterns from frozen values that are never mutated, allowing them to be treated as frozen.\n\n2. **Hoisted Context Declarations**: Special handling for variables declared with hoisting (`HoistedConst`, `HoistedFunction`, `HoistedLet`) to detect access before declaration.\n\n3. **Try-Catch Aliasing**: When a `maybe-throw` terminal is reached, call return values are aliased into the catch binding since exceptions can throw return values.\n\n4. **Function Expressions**: Functions are considered mutable only if they have mutable captures or tracked side effects (MutateFrozen, MutateGlobal, Impure).\n\n5. **Iterator Mutation**: Non-builtin iterators may alias their collection and mutation of the iterator is conditional.\n\n6. **Array.push and Similar**: Uses legacy signature system with `Store` effect on receiver and `Capture` of arguments.\n\n## TODOs\n- `// TODO: using InstructionValue as a bit of a hack, but it's pragmatic` - context variable initialization\n- `// TODO: call applyEffect() instead` - try-catch aliasing\n- `// TODO: make sure we're also validating against global mutations somewhere` - global mutation validation for effects/event handlers\n- `// TODO; include \"render\" here?` - whether to track Render effects in function hasTrackedSideEffects\n- `// TODO: consider using persistent data structures to make clone cheaper` - performance optimization for state cloning\n- `// TODO check this` and `// TODO: what kind here???` - DeclareLocal value kinds\n\n## Example\n\nFor the code:\n```javascript\nconst arr = [];\narr.push({});\narr.push(x, y);\n```\n\nAfter `InferMutationAliasingEffects`, the effects are:\n\n```\n[10] $39 = Array []\n    Create $39 = mutable           // Array literal creates mutable value\n\n[11] $41 = StoreLocal arr$40 = $39\n    Assign arr$40 = $39            // arr points to the array value\n    Assign $41 = $39\n\n[15] $45 = MethodCall $42.push($44)\n    Apply $45 = $42.$43($44)       // Records the call\n    Mutate $42                      // push mutates the array\n    Capture $42 <- $44             // {} is captured into array\n    Create $45 = primitive         // push returns number (length)\n\n[20] $50 = MethodCall $46.push($48, $49)\n    Apply $50 = $46.$47($48, $49)\n    Mutate $46                      // push mutates the array\n    Capture $46 <- $48             // x captured into array\n    Capture $46 <- $49             // y captured into array\n    Create $50 = primitive\n```\n\nThe key insight is that `Mutate` effects extend the mutable range of the array, and `Capture` effects record data flow so that if the array is later frozen (e.g., returned from a component), the captured values are also considered frozen for validation purposes.\n"

    "content": "# inferMutationAliasingRanges\n\n## File\n`src/Inference/InferMutationAliasingRanges.ts`\n\n## Purpose\nThis pass builds an abstract model of the heap and interprets the effects of the given function to determine: (1) the mutable ranges of all identifiers, (2) the externally-visible effects of the function (mutations of params/context-vars, aliasing relationships), and (3) the legacy `Effect` annotation for each Place.\n\n## Input Invariants\n- InferMutationAliasingEffects must have already run, populating `instr.effects` on each instruction with aliasing/mutation effects\n- SSA form must be established (identifiers are in SSA)\n- Type inference has been run (InferTypes)\n- Functions have been analyzed (AnalyseFunctions)\n- Dead code elimination has been performed\n\n## Output Guarantees\n- Every identifier has a populated `mutableRange` (start:end instruction IDs)\n- Every Place has a legacy `Effect` annotation (Read, Capture, Store, Freeze, etc.)\n- The function's `aliasingEffects` array is populated with externally-visible effects (mutations of params/context-vars, aliasing between params/context-vars/return)\n- Validation errors are collected for invalid effects like `MutateFrozen` or `MutateGlobal`\n\n## Algorithm\nThe pass operates in three main phases:\n\n**Part 1: Build Data Flow Graph and Infer Mutable Ranges**\n1. Creates an `AliasingState` which maintains a `Node` for each identifier\n2. Iterates through all blocks and instructions, processing effects in program order\n3. For each effect:\n   - `Create`/`CreateFunction`: Creates a new node in the graph\n   - `CreateFrom`/`Assign`/`Alias`: Adds alias edges between nodes (with ordering index)\n   - `MaybeAlias`: Adds conditional alias edges\n   - `Capture`: Adds capture edges (for transitive mutations)\n   - `Mutate*`: Queues mutations for later processing\n   - `Render`: Queues render effects for later processing\n4. Phi node operands are connected once their predecessor blocks have been visited\n5. After the graph is built, mutations are processed:\n   - Mutations propagate both forward (via edges) and backward (via aliases/captures)\n   - Each mutation extends the `mutableRange.end` of affected identifiers\n   - Transitive mutations also traverse capture edges backward\n   - `MaybeAlias` edges downgrade mutations to `Conditional`\n6. Render effects are processed to mark values as rendered\n\n**Part 2: Populate Legacy Per-Place Effects**\n- Sets legacy effects on lvalues and operands based on instruction effects and mutable ranges\n- Fixes up mutable range start values for identifiers that are mutated after creation\n\n**Part 3: Infer Externally-Visible Function Effects**\n- Creates a `Create` effect for the return value\n- Simulates transitive mutations of each param/context-var/return to detect capture relationships\n- Produces `Alias`/`Capture` effects showing data flow between params/context-vars/return\n\n## Key Data Structures\n\n### `AliasingState`\nThe main state class maintaining the data flow graph:\n- `nodes: Map<Identifier, Node>` - Maps identifiers to their graph nodes\n\n### `Node`\nRepresents an identifier in the data flow graph:\n```typescript\ntype Node = {\n  id: Identifier;\n  createdFrom: Map<Identifier, number>;   // CreateFrom edges (source -> index)\n  captures: Map<Identifier, number>;       // Capture edges (source -> index)\n  aliases: Map<Identifier, number>;        // Alias/Assign edges (source -> index)\n  maybeAliases: Map<Identifier, number>;   // MaybeAlias edges (source -> index)\n  edges: Array<{index, node, kind}>;       // Forward edges to other nodes\n  transitive: {kind: MutationKind; loc} | null;  // Transitive mutation info\n  local: {kind: MutationKind; loc} | null;       // Local mutation info\n  lastMutated: number;                     // Index of last mutation affecting this node\n  mutationReason: MutationReason | null;   // Reason for mutation\n  value: {kind: 'Object'} | {kind: 'Phi'} | {kind: 'Function'; function: HIRFunction};\n  render: Place | null;                    // Render context if used in JSX\n};\n```\n\n### `MutationKind`\nEnum describing mutation certainty:\n```typescript\nenum MutationKind {\n  None = 0,\n  Conditional = 1,  // May mutate (e.g., via MaybeAlias or MutateConditionally)\n  Definite = 2,     // Definitely mutates\n}\n```\n\n## Edge Cases\n\n### Phi Nodes\n- Phi nodes are created as special `{kind: 'Phi'}` nodes\n- Phi operands from predecessor blocks are processed with pending edges until the predecessor is visited\n- When traversing \"forwards\" through edges and encountering a phi, backward traversal is stopped (prevents mutation from one phi input affecting other inputs)\n\n### Transitive vs Local Mutations\n- Local mutations (`Mutate`) only affect alias/assign edges backward\n- Transitive mutations (`MutateTransitive`) also affect capture edges backward\n- Both affect all forward edges\n\n### MaybeAlias\n- Mutations through MaybeAlias edges are downgraded to `Conditional`\n- This prevents false positive errors when we cannot be certain about aliasing\n\n### Function Values\n- Functions are tracked specially as `{kind: 'Function'}` nodes\n- When a function is mutated (transitively), errors from the function body are propagated\n- This handles cases where mutating a captured value in a function affects render safety\n\n### Render Effect Propagation\n- Render effects traverse backward through alias/capture/createFrom edges\n- Functions that have not been mutated are skipped during render traversal (except for JSX-returning functions)\n- Ref types (`isUseRefType`) stop render traversal\n\n## TODOs\n1. Assign effects should have an invariant that the node is not initialized yet. Currently `InferFunctionExpressionAliasingEffectSignatures` infers Assign effects that should be Alias, causing reinitialization.\n\n2. Phi place effects are not properly set today.\n\n3. Phi mutable range start calculation is imprecise - currently just sets it to the instruction before the block rather than computing the exact start.\n\n## Example\n\nConsider the following code:\n```javascript\nfunction foo() {\n  let a = {};   // Create a (instruction 1)\n  let b = {};   // Create b (instruction 3)\n  a = b;        // Assign a <- b (instruction 8)\n  mutate(a, b); // MutateTransitiveConditionally a, b (instruction 16)\n  return a;\n}\n```\n\nThe pass builds a graph:\n1. Creates node for `{}` at instruction 1 (initially assigned to `a`)\n2. Creates node for `{}` at instruction 3 (initially assigned to `b`)\n3. At instruction 8, creates alias edge: `b -> a` with index 8\n4. At instruction 16, mutations are queued for `a` and `b`\n\nWhen processing the mutation of `a` at instruction 16:\n- Extends `a`'s mutableRange.end to 17\n- Traverses backward through alias edge to `b`, extends `b`'s mutableRange.end to 17\n- Since `a = b`, both objects must be considered mutable until instruction 17\n\nThe output shows identifiers with range annotations like `$25[3:17]` meaning:\n- `$25` is the identifier\n- `3` is the instruction where it was created\n- `17` is the instruction after which it is no longer mutated\n\nFor aliased values, the ranges are unified - all values that could be affected by a mutation have their ranges extended to include that mutation point.\n"

This information is critical for memoization: reactive places form the dependencies that, when changed, should invalidate cached values.\n\nA place is reactive if it derives from any source of reactivity:\n1. **Props** - Component parameters may change between renders\n2. **Hooks** - Hooks can access state or context which can change\n3. **`use` operator** - Can access context which may change\n4. **Mutation with reactive operands** - Values mutated in instructions that have reactive operands become reactive themselves\n5. **Conditional assignment based on reactive control flow** - Values assigned in branches controlled by reactive conditions become reactive\n\n## Input Invariants\n- HIR is in SSA form with phi nodes at join points\n- `inferMutationAliasingEffects` and `inferMutationAliasingRanges` have run, establishing:\n  - Effect annotations on operands (Effect.Capture, Effect.Store, Effect.Mutate, etc.)\n  - Mutable ranges on identifiers\n  - Aliasing relationships captured by `findDisjointMutableValues`\n- All operands have known effects (asserts on `Effect.Unknown`)\n\n## Output Guarantees\n- Every reactive Place has `place.reactive = true`\n- Reactivity is transitively complete (derived from reactive → reactive)\n- All identifiers in a mutable alias group share reactivity\n- Reactivity is propagated to operands used within nested function expressions\n\n## Algorithm\nThe algorithm uses **fixpoint iteration** to propagate reactivity forward through the control-flow graph:\n\n### Initialization\n1. Create a `ReactivityMap` backed by disjoint sets of mutably-aliased identifiers\n2. Mark all function parameters as reactive (props are reactive by definition)\n3. Create a `ControlDominators` helper to identify blocks controlled by reactive conditions\n\n### Fixpoint Loop\nIterate until no changes occur:\n\nFor each block:\n1. **Phi Nodes**: Mark phi nodes reactive if:\n   - Any operand is reactive, OR\n   - Any predecessor block is controlled by a reactive condition (control-flow dependency)\n\n2. **Instructions**: For each instruction:\n   - Track stable identifier sources (for hooks like `useRef`, `useState` dispatch)\n   - Check if any operand is reactive\n   - Hook calls and `use` operator are sources of reactivity\n   - If instruction has reactive input:\n     - Mark lvalues reactive (unless they are known-stable like `setState` functions)\n   - If instruction has reactive input OR is in reactive-controlled block:\n     - Mark mutable operands (Capture, Store, Mutate effects) as reactive\n\n3. **Terminals**: Check terminal operands for reactivity\n\n### Post-processing\nPropagate reactivity to inner functions (nested `FunctionExpression` and `ObjectMethod`).\n\n## Key Data Structures\n\n### ReactivityMap\n```typescript\nclass ReactivityMap {\n  hasChanges: boolean = false;           // Tracks if fixpoint changed\n  reactive: Set<IdentifierId> = new Set(); // Set of reactive identifiers\n  aliasedIdentifiers: DisjointSet<Identifier>; // Mutable alias groups\n}\n```\n- Uses disjoint sets so that when one identifier in an alias group becomes reactive, they all are effectively reactive\n- `isReactive(place)` checks and marks `place.reactive = true` as a side effect\n- `snapshot()` resets change tracking and returns whether changes occurred\n\n### StableSidemap\n```typescript\nclass StableSidemap {\n  map: Map<IdentifierId, {isStable: boolean}> = new Map();\n}\n```\nTracks sources of stability (e.g., `useState()[1]` dispatch function). Forward data-flow analysis that:\n- Records hook calls that return stable types\n- Propagates stability through PropertyLoad and Destructure from stable containers\n- Propagates through LoadLocal and StoreLocal\n\n### ControlDominators\nUses post-dominator frontier analysis to determine which blocks are controlled by reactive branch conditions.\n\n## Edge Cases\n\n### Backward Reactivity Propagation via Mutable Aliasing\n```javascript\nconst x = [];\nconst z = [x];\nx.push(props.input);\nreturn <div>{z}</div>;\n```\nHere `z` aliases `x` which is later mutated with reactive data. The disjoint set ensures `z` becomes reactive even though the mutation happens after its creation.\n\n### Stable Types Are Not Reactive\n```javascript\nconst [state, setState] = useState();\n// setState is stable - not marked reactive despite coming from reactive hook\n```\nThe `StableSidemap` tracks these and skips marking them reactive.\n\n### Ternary with Stable Values Still Reactive\n```javascript\nprops.cond ? setState1 : setState2\n```\nEven though both branches are stable types, the result depends on reactive control flow, so it cannot be marked non-reactive just based on type.\n\n### Phi Nodes with Reactive Predecessors\nWhen a phi's predecessor block is controlled by a reactive condition, the phi becomes reactive even if its operands are all non-reactive constants.\n\n## TODOs\nNo explicit TODO comments are present in the source file. However, comments note:\n\n- **ComputedLoads not handled for stability**: Only PropertyLoad propagates stability from containers, not ComputedLoad. The comment notes this is safe because stable containers have differently-typed elements, but ComputedLoad handling could be added.\n\n## Example\n\n### Fixture: `reactive-dependency-fixpoint.js`\n\n**Input:**\n```javascript\nfunction Component(props) {\n  let x = 0;\n  let y = 0;\n  while (x === 0) {\n    x = y;\n    y = props.value;\n  }\n  return [x];\n}\n```\n\n**Before InferReactivePlaces:**\n```\nbb1 (loop):\n  store x$26:TPhi:TPhi: phi(bb0: read x$21:TPrimitive, bb3: read x$32:TPhi)\n  store y$30:TPhi:TPhi: phi(bb0: read y$24:TPrimitive, bb3: read y$37)\n  ...\nbb3 (block):\n  [12] mutate? $35 = LoadLocal read props$19\n  [13] mutate? $36 = PropertyLoad read $35.value\n  [14] mutate? $38 = StoreLocal Reassign mutate? y$37 = read $36\n```\n\n**After InferReactivePlaces:**\n```\nbb1 (loop):\n  store x$26:TPhi{reactive}:TPhi: phi(bb0: read x$21:TPrimitive, bb3: read x$32:TPhi{reactive})\n  store y$30:TPhi{reactive}:TPhi: phi(bb0: read y$24:TPrimitive, bb3: read y$37{reactive})\n  [6] mutate? $27:TPhi{reactive} = LoadLocal read x$26:TPhi{reactive}\n  ...\nbb3 (block):\n  [12] mutate? $35{reactive} = LoadLocal read props$19{reactive}\n  [13] mutate? $36{reactive} = PropertyLoad read $35{reactive}.value\n  [14] mutate? $38{reactive} = StoreLocal Reassign mutate? y$37{reactive} = read $36{reactive}\n```\n\n**Key observations:**\n- `props$19` is marked `{reactive}` as a function parameter\n- The reactivity propagates through the loop:\n  - First iteration: `y$37` becomes reactive from `props.value`\n  - Second iteration: `x$32` becomes reactive from `y$30` (which is reactive via the phi from `y$37`)\n  - The phi nodes `x$26` and `y$30` become reactive because their bb3 operands are reactive\n- The fixpoint algorithm handles this backward propagation through the loop correctly\n- The final output `$40` is reactive, so the array `[x]` will be memoized with `x` as a dependency\n"

    "content": "# inferReactiveScopeVariables\n\n## File\n`src/ReactiveScopes/InferReactiveScopeVariables.ts`\n\n## Purpose\nThis is the **1st of 4 passes** that determine how to break a React function into discrete reactive scopes (independently memoizable units of code). Its specific responsibilities are:\n\n1. **Identify operands that mutate together** - Variables that are mutated in the same instruction must be placed in the same reactive scope\n2. **Assign a unique ReactiveScope to each group** - Each disjoint set of co-mutating identifiers gets assigned a unique ScopeId\n3. **Compute the mutable range** - The scope's range is computed as the union of all member identifiers' mutable ranges\n\nThe pass does NOT determine which instructions compute each scope, only which variables belong together.\n\n## Input Invariants\n- `InferMutationAliasingEffects` has run - Effects describe mutations, captures, and aliasing\n- `InferMutationAliasingRanges` has run - Each identifier has a valid `mutableRange` property\n- `InferReactivePlaces` has run - Places are marked as reactive or not\n- `RewriteInstructionKindsBasedOnReassignment` has run - Let/Const properly determined\n- All instructions have been numbered with valid `InstructionId` values\n- Phi nodes are properly constructed at block join points\n\n## Output Guarantees\n- Each identifier that is part of a mutable group has its `identifier.scope` property set to a `ReactiveScope` object\n- All identifiers in the same scope share the same `ReactiveScope` reference\n- The scope's `range` is the union (min start, max end) of all member mutable ranges\n- The scope's `range` is validated to be within [1, maxInstruction+1]\n- Identifiers that only have single-instruction lifetimes (read once) may not be assigned to a scope unless they allocate\n\n## Algorithm\n\n### Phase 1: Find Disjoint Mutable Values (`findDisjointMutableValues`)\n\nUses a Union-Find (Disjoint Set) data structure to group identifiers that mutate together:\n\n1. **Handle Phi Nodes**: For each phi in each block:\n   - If the phi's result is mutated after creation (mutableRange.end > first instruction in block), union the phi with all its operands\n   - This ensures values that flow through control flow and are later mutated are grouped together\n\n2. **Handle Instructions**: For each instruction:\n   - Collect mutable operands based on instruction type:\n     - If lvalue has extended mutable range OR instruction may allocate, include lvalue\n     - For StoreLocal/StoreContext: Include lvalue if it has extended mutable range, include value if mutable\n     - For Destructure: Include each pattern operand with extended range, include source if mutable\n     - For MethodCall: Include all mutable operands plus the computed property (to keep method resolution in same scope)\n     - For other instructions: Include all mutable operands\n   - Exclude global variables (mutableRange.start === 0) since they cannot be recreated\n   - Union all collected operands together\n\n### Phase 2: Assign Scopes\n\n1. Iterate over all identifiers in the disjoint set using `forEach(item, groupIdentifier)`\n2. For each unique group, create a new ReactiveScope:\n   - Generate a unique ScopeId from the environment\n   - Initialize range from the first member's mutableRange\n   - Set up empty dependencies, declarations, reassignments sets\n3. For subsequent members of the same group:\n   - Expand the scope's range to encompass the member's mutableRange\n   - Merge source locations\n4. Assign the scope to each identifier: `identifier.scope = scope`\n5. Update each identifier's mutableRange to match the scope's range\n\n**Validation**: After scope assignment, validate that all scopes have valid ranges within [1, maxInstruction+1].\n\n## Key Data Structures\n\n### DisjointSet<Identifier>\nA Union-Find data structure optimized for grouping items into disjoint sets:\n\n```typescript\nclass DisjointSet<T> {\n  #entries: Map<T, T>;  // Maps each item to its parent (root points to self)\n\n  union(items: Array<T>): void;     // Merge items into one set\n  find(item: T): T | null;          // Find the root of item's set (with path compression)\n  forEach(fn: (item, group) => void): void;  // Iterate all items with their group root\n}\n```\n\nPath compression is used during `find()` to flatten the tree structure, improving subsequent lookup performance.\n\n### ReactiveScope\n```typescript\ntype ReactiveScope = {\n  id: ScopeId;\n  range: MutableRange;              // [start, end) instruction range\n  dependencies: Set<ReactiveScopeDependency>;  // Inputs (populated later)\n  declarations: Map<IdentifierId, ReactiveScopeDeclaration>;  // Outputs (populated later)\n  reassignments: Set<Identifier>;   // Reassigned variables (populated later)\n  earlyReturnValue: {...} | null;   // For scopes with early returns\n  merged: Set<ScopeId>;             // IDs of scopes merged into this one\n  loc: SourceLocation;\n};\n```\n\n## Edge Cases\n\n### Global Variables\nExcluded from scopes (mutableRange.start === 0) since they cannot be recreated during memoization.\n\n### Phi Nodes After Mutation\nWhen a phi's result is mutated after the join point, all phi operands must be in the same scope to ensure the mutation can be recomputed correctly.\n\n### MethodCall Property Resolution\nThe computed property load for a method call is explicitly added to the same scope as the call itself.\n\n### Allocating Instructions\nInstructions that allocate (Array, Object, JSX, etc.) add their lvalue to the scope even if the lvalue has a single-instruction range.\n\n### Single-Instruction Ranges\nValues with range `[n, n+1)` (used exactly once) are only included if they allocate, otherwise they're just read.\n\n### enableForest Config\nWhen enabled, phi operands are unconditionally unioned with the phi result (even without mutation after the phi).\n\n## TODOs\n1. `// TODO: improve handling of module-scoped variables and globals` - The current approach excludes globals entirely, but a more nuanced handling could be beneficial.\n\n2. Known issue with aliasing and mutable lifetimes (from header comments):\n```javascript\nlet x = {};\nlet y = [];\nx.y = y; // RHS is not considered mutable here bc not further mutation\nmutate(x); // bc y is aliased here, it should still be considered mutable above\n```\nThis suggests the pass may miss some co-mutation relationships when aliasing is involved.\n\n## Example\n\n### Fixture: `reactive-scope-grouping.js`\n\n**Input:**\n```javascript\nfunction foo() {\n  let x = {};\n  let y = [];\n  let z = {};\n  y.push(z);  // y and z co-mutate (z captured into y)\n  x.y = y;    // x and y co-mutate (y captured into x)\n  return x;\n}\n```\n\n**After InferReactiveScopeVariables:**\n```\n[1] mutate? $19_@0[1:14] = Object { }     // x's initial object, scope @0\n[2] store $21_@0[1:14] = StoreLocal x     // x in scope @0\n[3] mutate? $22_@1[3:11] = Array []       // y's array, scope @1\n[4] store $24_@1[3:11] = StoreLocal y     // y in scope @1\n[5] mutate? $25_@2 = Object { }           // z's object, scope @2\n[10] MethodCall y.push(z)                 // Mutates y, captures z\n[13] PropertyStore x.y = y                // Mutates x, captures y\n```\n\nThe `y.push(z)` joins y and z into scope @1, and `x.y = y` joins x and y into scope @0. Because y is now in @0, and z was captured into y, ultimately x, y, and z all end up in the same scope @0.\n\n**Compiled Output:**\n```javascript\nfunction foo() {\n  const $ = _c(1);\n  let x;\n  if ($[0] === Symbol.for(\"react.memo_cache_sentinel\")) {\n    x = {};\n    const y = [];\n    const z = {};\n    y.push(z);\n    x.y = y;\n    $[0] = x;\n  } else {\n    x = $[0];\n  }\n  return x;\n}\n```\n\nAll three objects (x, y, z) are created within the same memoization block because they co-mutate and could potentially alias each other.\n"

    "content": "# rewriteInstructionKindsBasedOnReassignment\n\n## File\n`src/SSA/RewriteInstructionKindsBasedOnReassignment.ts`\n\n## Purpose\nRewrites the `InstructionKind` of variable declaration and assignment instructions to correctly reflect whether variables should be declared as `const` or `let` in the final output. It determines this based on whether a variable is subsequently reassigned after its initial declaration.\n\nThe key insight is that this pass runs **after dead code elimination (DCE)**, so a variable that was originally declared with `let` in the source (because it was reassigned) may be converted to `const` if the reassignment was removed by DCE. However, variables originally declared as `const` cannot become `let`.\n\n## Input Invariants\n- SSA form: Each identifier has a unique `IdentifierId` and `DeclarationId`\n- Dead code elimination has run: Unused assignments have been removed\n- Mutation/aliasing inference complete: Runs after `InferMutationAliasingRanges` and `InferReactivePlaces` in the main pipeline\n- All instruction kinds are initially set (typically `Let` for variables that may be reassigned)\n\n## Output Guarantees\n- **First declaration gets `Const` or `Let`**: The first `StoreLocal` for a named variable is marked as:\n  - `InstructionKind.Const` if the variable is never reassigned after\n  - `InstructionKind.Let` if the variable has subsequent reassignments\n- **Reassignments marked as `Reassign`**: Any subsequent `StoreLocal` to the same `DeclarationId` is marked as `InstructionKind.Reassign`\n- **Destructure consistency**: All places in a destructuring pattern must have consistent kinds (all Const or all Reassign)\n- **Update operations trigger Let**: `PrefixUpdate` and `PostfixUpdate` operations (like `++x` or `x--`) mark the original declaration as `Let`\n\n## Algorithm\n\n1. **Initialize declarations map**: Create a `Map<DeclarationId, LValue | LValuePattern>` to track declared variables.\n\n2. **Seed with parameters and context**: Add all named function parameters and captured context variables to the map with kind `Let` (since they're already \"declared\" outside the function body).\n\n3. **Process blocks in order**: Iterate through all blocks and instructions:\n\n   - **DeclareLocal**: Record the declaration in the map (invariant: must not already exist)\n\n   - **StoreLocal**:\n     - If not in map: This is the first store, add to map with `kind = Const`\n     - If already in map: This is a reassignment. Update original declaration to `Let`, set current instruction to `Reassign`\n\n   - **Destructure**:\n     - For each operand in the pattern, check if it's already declared\n     - All operands must be consistent (all new declarations OR all reassignments)\n     - Set pattern kind to `Const` for new declarations, `Reassign` for existing ones\n\n   - **PrefixUpdate / PostfixUpdate**: Look up the declaration and mark it as `Let` (these always imply reassignment)\n\n## Key Data Structures\n\n```typescript\n// Main tracking structure\nconst declarations = new Map<DeclarationId, LValue | LValuePattern>();\n\n// InstructionKind enum (from HIR.ts)\nenum InstructionKind {\n  Const = 'Const',      // const declaration\n  Let = 'Let',          // let declaration\n  Reassign = 'Reassign', // reassignment to existing binding\n  Catch = 'Catch',      // catch clause binding\n  HoistedLet = 'HoistedLet',     // hoisted let\n  HoistedConst = 'HoistedConst', // hoisted const\n  HoistedFunction = 'HoistedFunction', // hoisted function\n  Function = 'Function', // function declaration\n}\n```\n\n## Edge Cases\n\n### DCE Removes Reassignment\nA `let x = 0; x = 1;` where `x = 1` is unused becomes `const x = 0;` after DCE.\n\n### Destructuring with Mixed Operands\nThe invariant checks ensure all operands in a destructure pattern are either all new declarations or all reassignments. Mixed cases cause a compiler error.\n\n### Value Blocks with DCE\nThere's a TODO for handling reassignment in value blocks where the original declaration was removed by DCE.\n\n### Parameters and Context Variables\nThese are pre-seeded as `Let` in the declarations map since they're conceptually \"declared\" at function entry.\n\n### Update Expressions\n`++x` and `x--` always mark the variable as `Let`, even if used inline.\n\n## TODOs\n```typescript\nCompilerError.invariant(block.kind !== 'value', {\n  reason: `TODO: Handle reassignment in a value block where the original\n           declaration was removed by dead code elimination (DCE)`,\n  ...\n});\n```\n\nThis indicates an edge case where a destructuring reassignment occurs in a value block but the original declaration was eliminated by DCE. This is currently an invariant violation rather than handled gracefully.\n\n## Example\n\n### Fixture: `reassignment.js`\n\n**Input Source:**\n```javascript\nfunction Component(props) {\n  let x = [];\n  x.push(props.p0);\n  let y = x;\n\n  x = [];\n  let _ = <Component x={x} />;\n\n  y.push(props.p1);\n\n  return <Component x={x} y={y} />;\n}\n```\n\n**Before Pass (InferReactivePlaces output):**\n```\n[2] StoreLocal Let x$32 = $31      // x is initially marked Let\n[9] StoreLocal Let y$40 = $39      // y is initially marked Let\n[11] StoreLocal Reassign x$43 = $42  // reassignment already marked\n```\n\n**After Pass:**\n```\n[2] StoreLocal Let x$32 = $31      // x stays Let (has reassignment at line 11)\n[9] StoreLocal Const y$40 = $39    // y becomes Const (never reassigned)\n[11] StoreLocal Reassign x$43 = $42  // stays Reassign\n```\n\n**Final Generated Code:**\n```javascript\nfunction Component(props) {\n  const $ = _c(4);\n  let t0;\n  if ($[0] !== props.p0 || $[1] !== props.p1) {\n    let x = [];              // let because reassigned\n    x.push(props.p0);\n    const y = x;             // const because never reassigned\n    // ... x = t1; (reassignment)\n    y.push(props.p1);\n    t0 = <Component x={x} y={y} />;\n    // ...\n  }\n  return t0;\n}\n```\n\nThe pass correctly identified that `x` needs `let` (since it's reassigned on line 6 of the source) while `y` can use `const` (it's never reassigned after initialization).\n\n## Where This Pass is Called\n\n1. **Main Pipeline** (`src/Entrypoint/Pipeline.ts:322`): Called after `InferReactivePlaces` and before `InferReactiveScopeVariables`.\n\n2. **AnalyseFunctions** (`src/Inference/AnalyseFunctions.ts:58`): Called when lowering inner function expressions as part of the function analysis phase.\n"

    "content": "# alignMethodCallScopes\n\n## File\n`src/ReactiveScopes/AlignMethodCallScopes.ts`\n\n## Purpose\nEnsures that `MethodCall` instructions and their associated `PropertyLoad` instructions (which load the method being called) have consistent scope assignments. The pass enforces one of two invariants:\n1. Both the MethodCall lvalue and the property have the **same** reactive scope\n2. **Neither** has a reactive scope\n\nThis alignment is critical because the PropertyLoad and MethodCall are semantically a single operation (`receiver.method(args)`) and must be memoized together as a unit. If they had different scopes, the generated code would incorrectly try to memoize the property load separately from the method call, which could break correctness.\n\n## Input Invariants\n- The function has been converted to HIR form\n- `inferReactiveScopeVariables` has already run, assigning initial reactive scopes to identifiers based on mutation analysis\n- Each instruction's lvalue has an `identifier.scope` that is either a `ReactiveScope` or `null`\n- For `MethodCall` instructions, the `value.property` field contains a `Place` referencing the loaded method\n\n## Output Guarantees\nAfter this pass runs:\n- For every `MethodCall` instruction in the function:\n  - If the lvalue has a scope AND the property has a scope, they point to the **same merged scope**\n  - If only the lvalue has a scope, the property's scope is set to match the lvalue's scope\n  - If only the property has a scope, the property's scope is set to `null` (so neither has a scope)\n- Merged scopes have their `range` extended to cover the union of the original scopes' ranges\n- Nested functions (FunctionExpression, ObjectMethod) are recursively processed\n\n## Algorithm\n\n### Phase 1: Collect Scope Relationships\n```\nFor each instruction in all blocks:\n  If instruction is a MethodCall:\n    lvalueScope = instruction.lvalue.identifier.scope\n    propertyScope = instruction.value.property.identifier.scope\n\n    If both have scopes:\n      Record that these scopes should be merged (using DisjointSet.union)\n    Else if only lvalue has scope:\n      Record that property should be assigned to lvalueScope\n    Else if only property has scope:\n      Record that property should be assigned to null (no scope)\n\n  If instruction is FunctionExpression or ObjectMethod:\n    Recursively process the nested function\n```\n\n### Phase 2: Merge Scopes\n```\nFor each merged scope group:\n  Pick a \"root\" scope\n  Extend root's range to cover all merged scopes:\n    root.range.start = min(all scope start points)\n    root.range.end = max(all scope end points)\n```\n\n### Phase 3: Apply Changes\n```\nFor each instruction:\n  If lvalue was recorded for remapping:\n    Set identifier.scope to the mapped value\n  Else if identifier has a scope that was merged:\n    Set identifier.scope to the merged root scope\n```\n\n## Key Data Structures\n\n1. **`scopeMapping: Map<IdentifierId, ReactiveScope | null>`**\n   - Maps property identifier IDs to their new scope assignment\n   - Value of `null` means the scope should be removed\n\n2. **`mergedScopes: DisjointSet<ReactiveScope>`**\n   - Union-find data structure tracking scopes that need to be merged\n   - Used when both MethodCall and property have different scopes\n\n3. **`ReactiveScope`** (from HIR)\n   - Contains `range: { start: InstructionId, end: InstructionId }`\n   - The range defines which instructions are part of the scope\n\n## Edge Cases\n\n### Both Have the Same Scope Already\nNo action needed (implicit in the logic).\n\n### Nested Functions\nThe pass recursively processes `FunctionExpression` and `ObjectMethod` instructions to handle closures.\n\n### Multiple MethodCalls Sharing Scopes\nThe DisjointSet handles transitive merging - if A merges with B, and B merges with C, all three end up in the same scope.\n\n### Property Without Scope, MethodCall Without Scope\nNo action needed (both already aligned at `null`).\n\n## TODOs\nThere are no explicit TODO comments in the source code.\n\n## Example\n\n### Fixture: `alias-capture-in-method-receiver.js`\n\n**Source code:**\n```javascript\nfunction Component() {\n  let a = someObj();\n  let x = [];\n  x.push(a);\n  return [x, a];\n}\n```\n\n**Before AlignMethodCallScopes:**\n```\n[7] store $24_@1[4:10]:TFunction = PropertyLoad capture $23_@1.push\n[9] mutate? $26:TPrimitive = MethodCall store $23_@1.read $24_@1(capture $25)\n```\n- PropertyLoad result `$24_@1` has scope `@1`\n- MethodCall result `$26` has no scope (`null`)\n\n**After AlignMethodCallScopes:**\n```\n[7] store $24[4:10]:TFunction = PropertyLoad capture $23_@1.push\n[9] mutate? $26:TPrimitive = MethodCall store $23_@1.read $24(capture $25)\n```\n- PropertyLoad result `$24` now has **no scope** (the `_@1` suffix removed)\n- MethodCall result `$26` still has no scope\n\n**Why this matters:**\nWithout this alignment, later passes might try to memoize the `.push` property load separately from the actual `push()` call. This would be incorrect because:\n1. Reading a method from an object and calling it are semantically one operation\n2. The property load's value (the bound method) is only valid immediately when called on the same receiver\n3. Separate memoization could lead to stale method references or incorrect this-binding\n"

This is critical for code generation because JavaScript requires object method definitions to be inlined within their containing object literals. If the object method and object expression were in different reactive scopes (which map to different memoization blocks), the generated code would be invalid since you cannot reference an object method defined in one block from an object literal in a different block.\n\nFrom the file's documentation:\n> \"To produce a well-formed JS program in Codegen, object methods and object expressions must be in the same ReactiveBlock as object method definitions must be inlined.\"\n\n## Input Invariants\n- Reactive scopes have been inferred: This pass runs after `InferReactiveScopeVariables`\n- ObjectMethod and ObjectExpression have non-null scopes: The pass asserts this with an invariant check\n- Scopes are disjoint across functions: The pass assumes that scopes do not overlap between parent and nested functions\n\n## Output Guarantees\n- ObjectMethod and ObjectExpression share the same scope: Any ObjectMethod used as a property in an ObjectExpression will have its scope merged with the ObjectExpression's scope\n- Merged scope covers both ranges: The resulting merged scope's range is expanded to cover the minimum start and maximum end of all merged scopes\n- All identifiers are repointed: All identifiers whose scopes were merged are updated to point to the canonical root scope\n- Inner functions are also processed: The pass recursively handles nested ObjectMethod and FunctionExpression values\n\n## Algorithm\n\n### Phase 1: Find Scopes to Merge (`findScopesToMerge`)\n1.

Uses path compression for efficient `find()` operations.\n\n2. **Set<Identifier>** - Tracks which identifiers are ObjectMethod declarations, used to identify when an ObjectExpression operand is an object method.\n\n3. **ReactiveScope** - Contains:\n   - `id: ScopeId` - Unique identifier\n   - `range: MutableRange` - Start and end instruction IDs\n   - `dependencies` - Inputs to the scope\n   - `declarations` - Values produced by the scope\n\n4. **MutableRange** - Has `start` and `end` InstructionId fields that define the scope's extent.\n\n## Edge Cases\n\n### Nested Object Methods\nWhen an object method itself contains another object with methods, the pass recursively processes inner functions first before handling the outer function's scopes.\n\n### Multiple Object Methods in Same Object\nIf an object has multiple method properties, all their scopes will be merged with the object's scope through the DisjointSet.\n\n### Object Methods in Conditional Expressions\nObject methods inside ternary expressions still need scope alignment to ensure the method and its containing object are in the same reactive block.\n\n### Method Call After Object Creation\nThe pass works in conjunction with `AlignMethodCallScopes` (which runs immediately before) to ensure that method calls on objects with object methods are also properly scoped.\n\n## TODOs\nNone explicitly marked in the source file.\n\n## Example\n\n### Fixture: `object-method-shorthand.js`\n\n**Input:**\n```javascript\nfunction Component() {\n  let obj = {\n    method() {\n      return 1;\n    },\n  };\n  return obj.method();\n}\n```\n\n**Before AlignObjectMethodScopes:**\n```\nInferReactiveScopeVariables:\n  [1] mutate? $12_@0:TObjectMethod = ObjectMethod ...    // scope @0\n  [2] mutate? $14_@1[2:7]:TObject = Object { method: ... } // scope @1 (range 2:7)\n```\nThe ObjectMethod `$12` is in scope `@0` while the ObjectExpression `$14` is in scope `@1` with range `[2:7]`.\n\n**After AlignObjectMethodScopes:**\n```\nAlignObjectMethodScopes:\n  [1] mutate? $12_@0[1:7]:TObjectMethod = ObjectMethod ... // scope @0, range now 1:7\n  [2] mutate? $14_@0[1:7]:TObject = Object { method: ... } // also scope @0, range 1:7\n```\nBoth identifiers are in the same scope `@0`, and the scope's range has been expanded to `[1:7]` to cover both instructions.\n\n**Final Generated Code:**\n```javascript\nfunction Component() {\n  const $ = _c(1);\n  let t0;\n  if ($[0] === Symbol.for(\"react.memo_cache_sentinel\")) {\n    const obj = {\n      method() {\n        return 1;\n      },\n    };\n    t0 = obj.method();\n    $[0] = t0;\n  } else {\n    t0 = $[0];\n  }\n  return t0;\n}\n```\n\nThe object literal with its method and the subsequent method call are all inside the same memoization block, producing valid JavaScript where the method definition is inlined within the object literal.\n"

    "content": "# alignReactiveScopesToBlockScopesHIR\n\n## File\n`src/ReactiveScopes/AlignReactiveScopesToBlockScopesHIR.ts`\n\n## Purpose\nThis is the **2nd of 4 passes** that determine how to break a function into discrete reactive scopes (independently memoizable units of code). The pass aligns reactive scope boundaries to control flow (block scope) boundaries.\n\nThe problem it solves: Prior inference passes assign reactive scopes to operands based on mutation ranges at arbitrary instruction points in the control-flow graph. However, to generate memoization blocks around instructions, scopes must be aligned to block-scope boundaries -- you cannot memoize half of a loop or half of an if-block.\n\n**Example from the source code comments:**\n```javascript\nfunction foo(cond, a) {\n                    // original scope end\n                         // expanded scope end\n   const x = [];    |    |\n   if (cond) {      |    |\n     ...            |    |\n     x.push(a);     <--- original scope ended here\n     ...                 |\n   }                     <--- scope must extend to here\n}\n```\n\n## Input Invariants\n- `InferReactiveScopeVariables` has run: Each identifier has been assigned a `ReactiveScope` with a `range` (start/end instruction IDs) based on mutation analysis\n- The HIR is in SSA form: Blocks have unique IDs, instructions have unique IDs, and control flow is represented with basic blocks\n- Each block has a terminal with possible successors and fallthroughs\n- Each scope has a mutable range `{start: InstructionId, end: InstructionId}` indicating when the scope is active\n\n## Output Guarantees\n- **Scopes end at valid block boundaries**: A reactive scope may only end at the same block scope level as it began. The scope's `range.end` is updated to the first instruction of the fallthrough block after any control flow structure that the scope overlaps\n- **Scopes start at valid block boundaries**: For labeled breaks (gotos to a label), scopes that extend beyond the goto have their `range.start` extended back to include the label\n- **Value blocks (ternary, logical, optional) are handled specially**: Scopes inside value blocks are extended to align with the outer block scope's instruction range\n\n## Algorithm\n\nThe pass performs a single forward traversal over all blocks:\n\n### 1. Tracking Active Scopes\n- Maintains `activeScopes: Set<ReactiveScope>` - scopes whose range overlaps the current block\n- Maintains `activeBlockFallthroughRanges: Array<{range, fallthrough}>` - stack of pending block-fallthrough ranges\n\n### 2. Per-Block Processing\nFor each block:\n- Prune `activeScopes` to only those that extend past the current block's start\n- If this block is a fallthrough target, pop the range from the stack and extend all active scopes' start to the range start\n\n### 3. Recording Places\nFor each instruction lvalue and operand:\n- If the place has a scope, add it to `activeScopes`\n- If inside a value block, extend the scope's range to match the value block's outer range\n\n### 4. Handling Block Fallthroughs\nWhen a terminal has a fallthrough (not a simple branch):\n- Extend all active scopes whose `range.end > terminal.id` to at least the first instruction of the fallthrough block\n- Push the fallthrough range onto the stack for future scopes\n\n### 5. Handling Labeled Breaks (Goto)\nWhen encountering a goto to a label (not the natural fallthrough):\n- Find the corresponding fallthrough range on the stack\n- Extend all active scopes to span from the label start to its fallthrough end\n\n### 6. Value Block Handling\nFor ternary, logical, and optional terminals:\n- Create `ValueBlockNode` to track the outer block's instruction range\n- Scopes inside value blocks inherit this range, ensuring they align to the outer block scope\n\n## Key Data Structures\n\n```typescript\ntype ValueBlockNode = {\n  kind: 'node';\n  id: InstructionId;\n  valueRange: MutableRange;  // Range of outer block scope\n  children: Array<ValueBlockNode | ReactiveScopeNode>;\n};\n\ntype ReactiveScopeNode = {\n  kind: 'scope';\n  id: InstructionId;\n  scope: ReactiveScope;\n};\n\n// Tracked during traversal:\nactiveBlockFallthroughRanges: Array<{\n  range: InstructionRange;\n  fallthrough: BlockId;\n}>;\nactiveScopes: Set<ReactiveScope>;\nvalueBlockNodes: Map<BlockId, ValueBlockNode>;\n```\n\n## Edge Cases\n\n### Labeled Breaks\nWhen a `goto` jumps to a label (not the natural fallthrough), scopes must be extended to include the entire labeled block range, preventing the break from jumping out of the scope.\n\n### Value Blocks (Ternary/Logical/Optional)\nThese create nested \"value\" contexts. Scopes inside must be aligned to the outer block scope's boundaries, not the value block's boundaries.\n\n### Nested Control Flow\nDeeply nested if-statements require the scope to be extended through all levels back to the outermost block where the scope started.\n\n### do-while and try/catch\nThe terminal's successor might be a block (not value block), which is handled specially.\n\n## TODOs\n1. `// TODO: consider pruning activeScopes per instruction` - Currently, `activeScopes` is only pruned at block start points. Some scopes may no longer be active by the time a goto is encountered.\n\n2. `// TODO: add a variant of eachTerminalSuccessor() that visits _all_ successors, not just those that are direct successors for normal control-flow ordering.` - The current implementation uses `mapTerminalSuccessors` which may not visit all successors in all cases.\n\n## Example\n\n### Fixture: `extend-scopes-if.js`\n\n**Input:**\n```javascript\nfunction foo(a, b, c) {\n  let x = [];\n  if (a) {\n    if (b) {\n      if (c) {\n        x.push(0);  // Mutation of x ends here (instruction 12-13)\n      }\n    }\n  }\n  if (x.length) {  // instruction 16\n    return x;\n  }\n  return null;\n}\n```\n\n**Before AlignReactiveScopesToBlockScopesHIR:**\n```\nx$23_@0[1:13]  // Scope range 1-13\n```\nThe scope for `x` ends at instruction 13 (inside the innermost if block).\n\n**After AlignReactiveScopesToBlockScopesHIR:**\n```\nx$23_@0[1:16]  // Scope range extended to 1-16\n```\nThe scope is extended to instruction 16 (the first instruction after all the nested if-blocks), aligning to the block scope boundary.\n\n**Generated Code:**\n```javascript\nfunction foo(a, b, c) {\n  const $ = _c(4);\n  let x;\n  if ($[0] !== a || $[1] !== b || $[2] !== c) {\n    x = [];\n    if (a) {\n      if (b) {\n        if (c) {\n          x.push(0);\n        }\n      }\n    }\n    // Scope ends here, after ALL the if-blocks\n    $[0] = a;\n    $[1] = b;\n    $[2] = c;\n    $[3] = x;\n  } else {\n    x = $[3];\n  }\n  // Code outside the scope\n  if (x.length) {\n    return x;\n  }\n  return null;\n}\n```\n\nThe memoization block correctly wraps the entire nested if-structure, not just part of it.\n"

It merges reactive scopes that would otherwise be inconsistent with each other due to:\n\n1. **Overlapping ranges**: Scopes whose instruction ranges partially overlap (not disjoint and not nested) must be merged because the compiler cannot produce valid `if-else` memo blocks for overlapping scopes.\n\n2. **Cross-scope mutations**: When an instruction within one scope mutates a value belonging to a different (outer) scope, those scopes must be merged to maintain correctness.\n\nThe pass guarantees that after execution, any two reactive scopes are either:\n- Entirely disjoint (no common instructions)\n- Properly nested (one scope is completely contained within the other)\n\n## Input Invariants\n- Reactive scope variables have been inferred (`InferReactiveScopeVariables` pass has run)\n- Scopes have been aligned to block scopes (`AlignReactiveScopesToBlockScopesHIR` pass has run)\n- Each `Place` may have an associated `ReactiveScope` with a `range` (start/end instruction IDs)\n- Scopes may still have overlapping ranges or contain instructions that mutate outer scopes\n\n## Output Guarantees\n- **No overlapping scopes**: All reactive scopes either are disjoint or properly nested\n- **Consistent mutation boundaries**: Instructions only mutate their \"active\" scope (the innermost containing scope)\n- **Merged scope ranges**: Merged scopes have their ranges extended to cover the union of all constituent scopes\n- **Updated references**: All `Place` references have their `identifier.scope` updated to point to the merged scope\n\n## Algorithm\n\n### Phase 1: Collect Scope Information (`collectScopeInfo`)\n- Iterates through all instructions and terminals in the function\n- Records for each `Place`:\n  - The scope it belongs to (`placeScopes` map)\n  - When scopes start and end (`scopeStarts` and `scopeEnds` arrays, sorted in descending order by ID)\n- Only records scopes with non-empty ranges (`range.start !== range.end`)\n\n### Phase 2: Detect Overlapping Scopes (`getOverlappingReactiveScopes`)\nUses a stack-based traversal to track \"active\" scopes at each instruction:\n\n1. **For each instruction/terminal**:\n   - **Handle scope endings**: Pop completed scopes from the active stack. If a scope ends while other scopes that started later are still active (detected by finding the scope is not at the top of the stack), those scopes overlap and must be merged via `DisjointSet.union()`.\n\n   - **Handle scope starts**: Push new scopes onto the active stack (sorted by end time descending so earlier-ending scopes are at the top). Merge any scopes that have identical start/end ranges.\n\n   - **Handle mutations**: For each operand/lvalue, if it:\n     - Has an associated scope\n     - Is mutable at the current instruction\n     - The scope is active but not at the top of the stack (i.e., an outer scope)\n\n     Then merge all scopes from the mutated outer scope to the top of the stack.\n\n2. **Special case**: Primitive operands in `FunctionExpression` and `ObjectMethod` are skipped.\n\n### Phase 3: Merge Scopes and Rewrite References\n1. For each scope in the disjoint set, compute the merged range as the union (min start, max end)\n2. Update all `Place.identifier.scope` references to point to the merged \"group\" scope\n\n## Key Data Structures\n\n### ScopeInfo\n```typescript\ntype ScopeInfo = {\n  scopeStarts: Array<{id: InstructionId; scopes: Set<ReactiveScope>}>;\n  scopeEnds: Array<{id: InstructionId; scopes: Set<ReactiveScope>}>;\n  placeScopes: Map<Place, ReactiveScope>;\n};\n```\n\n### TraversalState\n```typescript\ntype TraversalState = {\n  joined: DisjointSet<ReactiveScope>;  // Union-find for merged scopes\n  activeScopes: Array<ReactiveScope>;   // Stack of currently active scopes\n};\n```\n\n### DisjointSet<ReactiveScope>\nA union-find data structure that tracks which scopes should be merged into the same group.\n\n## Edge Cases\n\n### Identical Scope Ranges\nWhen multiple scopes have the exact same start and end, they are automatically merged since they would produce the same reactive block.\n\n### Empty Scopes\nScopes where `range.start === range.end` are skipped entirely.\n\n### Primitive Captures in Functions\nWhen a `FunctionExpression` or `ObjectMethod` captures a primitive operand, it's excluded from scope merging analysis.\n\n### JSX Single-Instruction Scopes\nThe comment in the code notes this isn't perfect - mutating scopes may get merged with JSX single-instruction scopes.\n\n### Non-Mutating Captures\nThe pass records both mutating and non-mutating scopes to handle cases where still-mutating values are aliased by inner scopes.\n\n## TODOs\nFrom the comments in the source file, the design constraints arise from the current compiler output design:\n- **Instruction ordering is preserved**: If reordering were allowed, disjoint ranges could be produced by reordering mutating instructions\n- **One if-else block per scope**: The current design doesn't allow composing a reactive scope from disconnected instruction ranges\n\n## Example\n\n### Fixture: `overlapping-scopes-interleaved.js`\n\n**Input Code:**\n```javascript\nfunction foo(a, b) {\n  let x = [];\n  let y = [];\n  x.push(a);\n  y.push(b);\n}\n```\n\n**Before MergeOverlappingReactiveScopesHIR:**\n```\n[1] $20_@0[1:9] = Array []        // x belongs to scope @0, range [1:9]\n[2] x$21_@0[1:9] = StoreLocal...\n[3] $23_@1[3:13] = Array []       // y belongs to scope @1, range [3:13]\n[4] y$24_@1[3:13] = StoreLocal...\n```\nScopes @0 [1:9] and @1 [3:13] overlap: @0 starts at 1, @1 starts at 3, @0 ends at 9, @1 ends at 13. This is invalid.\n\n**After MergeOverlappingReactiveScopesHIR:**\n```\n[1] $20_@0[1:13] = Array []       // Merged scope @0, range [1:13]\n[2] x$21_@0[1:13] = StoreLocal...\n[3] $23_@0[1:13] = Array []       // Now also scope @0\n[4] y$24_@0[1:13] = StoreLocal...\n```\n\nBoth `x` and `y` now belong to the same merged scope @0 with range [1:13], producing a single `if-else` memo block in the output.\n"

It converts the implicit scope ranges (stored on identifiers as `identifier.scope.range`) into explicit control flow structure by:\n\n1. Inserting a `scope` terminal at the **start** of each reactive scope\n2. Inserting a `goto` terminal at the **end** of each reactive scope\n3. Creating fallthrough blocks to properly connect the scopes to the rest of the CFG\n\nThis transformation makes scope boundaries first-class elements in the CFG, which is essential for later passes that generate the memoization code (the `if ($[n] !== dep)` checks).\n\n## Input Invariants\n- **Properly nested scopes and blocks**: The pass assumes `assertValidBlockNesting` has passed, meaning all program blocks and reactive scopes form a proper tree hierarchy\n- **Aligned scope ranges**: Reactive scope ranges have been correctly aligned and merged by previous passes\n- **Valid instruction IDs**: All instructions have sequential IDs that define the scope boundaries\n- **Scopes attached to identifiers**: Reactive scopes are found by traversing all `Place` operands and collecting unique non-empty scopes\n\n## Output Guarantees\n- **Explicit scope terminals**: Each reactive scope is represented in the CFG as a `ReactiveScopeTerminal` with:\n  - `block` - The BlockId containing the scope's instructions\n  - `fallthrough` - The BlockId that executes after the scope\n- **Proper block structure**: Original blocks are split at scope boundaries\n- **Restored HIR invariants**: The pass restores RPO ordering, predecessor sets, instruction IDs, and scope/identifier ranges\n- **Updated phi nodes**: Phi operands are repointed when their source blocks are split\n\n## Algorithm\n\n### Step 1: Collect Scope Rewrites\n```\nfor each reactive scope (in range pre-order):\n  push StartScope rewrite at scope.range.start\n  push EndScope rewrite at scope.range.end\n```\nThe `recursivelyTraverseItems` helper traverses scopes in pre-order (outer scopes before inner scopes).\n\n### Step 2: Apply Rewrites by Splitting Blocks\n```\nreverse queuedRewrites (to pop in ascending instruction order)\nfor each block:\n  for each instruction (or terminal):\n    while there are rewrites <= current instruction ID:\n      split block at current index\n      insert scope terminal (for start) or goto terminal (for end)\n  emit final block segment with original terminal\n```\n\n### Step 3: Repoint Phi Nodes\nWhen a block is split, its final segment gets a new BlockId.

The compiler does not yet support memoization within loops because:\n\n1. Loop iterations would require reconciliation across runs (similar to how `key` is used in JSX for lists)\n2. There is no way to identify values across iterations\n3. The current approach is to memoize *around* the loop rather than *within* it\n\nWhen a reactive scope is found inside a loop body, the pass converts its terminal from `scope` to `pruned-scope`. A `pruned-scope` terminal is later treated specially during codegen - its instructions are emitted inline without any memoization guards.\n\n## Input Invariants\n- The HIR has been through `buildReactiveScopeTerminalsHIR`, which creates `scope` terminal nodes for reactive scopes\n- The HIR is in valid block form with proper terminal kinds\n- The block ordering respects control flow (blocks are iterated in order, with loop fallthroughs appearing after loop bodies)\n\n## Output Guarantees\n- All `scope` terminals that appear inside any loop body are converted to `pruned-scope` terminals\n- Scopes outside of loops remain unchanged as `scope` terminals\n- The structure of blocks is preserved; only the terminal kind is mutated\n- The `pruned-scope` terminal retains all the same fields as `scope` (block, fallthrough, scope, id, loc)\n\n## Algorithm\n\nThe algorithm uses a **linear scan with a stack-based loop tracking** approach:\n\n```\n1. Initialize an empty array `activeLoops` to track which loop(s) we are currently inside\n2. For each block in the function body (in order):\n   a. Remove the current block ID from activeLoops (if present)\n      - This happens when we reach a loop's fallthrough block, exiting the loop\n   b. Examine the block's terminal:\n      - If it's a loop terminal (do-while, for, for-in, for-of, while):\n        Push the loop's fallthrough block ID onto activeLoops\n      - If it's a scope terminal AND activeLoops is non-empty:\n        Convert the terminal to pruned-scope (keeping all other fields)\n      - All other terminal kinds are ignored\n```\n\nKey insight: The algorithm tracks when we \"enter\" a loop by pushing the fallthrough ID when encountering a loop terminal, and \"exits\" the loop when that fallthrough block is visited.\n\n## Key Data Structures\n\n### activeLoops: Array<BlockId>\nA stack of block IDs representing loop fallthroughs.

A scope deep inside multiple nested loops will still be pruned.\n\n### Scope Spanning the Loop\nIf a scope terminal appears before the loop terminal but its body contains the loop, it is NOT pruned because the scope terminal itself is not inside the loop.\n\n### Multiple Loops in Sequence\nWhen exiting one loop (reaching its fallthrough) and entering another, `activeLoops` correctly clears the first loop before potentially adding the second.\n\n### Control Flow That Exits Loops (break/return)\nThe algorithm relies on block ordering and fallthrough IDs. Early exits via break/return don't affect the tracking since we track by fallthrough block ID.\n\n## TODOs\nNo explicit TODOs in this file. However, the docstring mentions future improvements:\n> \"Eventually we may integrate more deeply into the runtime so that we can do a single level of reconciliation\"\n\nThis suggests a potential future feature to support memoization within loops via runtime integration.\n\n## Example\n\n### Fixture: `repro-memoize-for-of-collection-when-loop-body-returns.js`\n\n**Input:**\n```javascript\nfunction useHook(nodeID, condition) {\n  const graph = useContext(GraphContext);\n  const node = nodeID != null ? graph[nodeID] : null;\n\n  for (const key of Object.keys(node?.fields ?? {})) {\n    if (condition) {\n      return new Class(node.fields?.[field]);  // <-- Scope @4 is here\n    }\n  }\n  return new Class();  // <-- Scope @5 is here (outside loop)\n}\n```\n\n**Before FlattenReactiveLoopsHIR:**\n```\n[45] Scope scope @3 [45:72] ... block=bb35 fallthrough=bb36\nbb35:\n  [46] ForOf init=bb6 test=bb7 loop=bb8 fallthrough=bb5\n  ...\n  [66] Scope scope @4 [66:69] ... block=bb37 fallthrough=bb38  <-- Inside loop\n  ...\n  [73] Scope scope @5 [73:76] ... block=bb39 fallthrough=bb40  <-- Outside loop\n```\n\n**After FlattenReactiveLoopsHIR:**\n```\n[45] Scope scope @3 [45:72] ... block=bb35 fallthrough=bb36    <-- Unchanged\n...\n[66] <pruned> Scope scope @4 [66:69] ... block=bb37 fallthrough=bb38  <-- PRUNED!\n...\n[73] Scope scope @5 [73:76] ... block=bb39 fallthrough=bb40    <-- Unchanged\n```\n\n**Final Codegen Result:**\n```javascript\nfunction useHook(nodeID, condition) {\n  const $ = _c(7);\n  // ... memoized Object.keys call (scope @2)\n\n  let t1;\n  if ($[2] !== condition || $[3] !== node || $[4] !== t0) {\n    // Scope @3 wraps the loop\n    t1 = Symbol.for(\"react.early_return_sentinel\");\n    bb0: for (const key of t0) {\n      if (condition) {\n        t1 = new Class(node.fields?.[field]);  // Scope @4 was PRUNED - no memoization\n        break bb0;\n      }\n    }\n    $[2] = condition;\n    $[3] = node;\n    $[4] = t0;\n    $[5] = t1;\n  } else {\n    t1 = $[5];\n  }\n  // ...\n\n  // Scope @5 - memoized (sentinel check)\n  if ($[6] === Symbol.for(\"react.memo_cache_sentinel\")) {\n    t2 = new Class();\n    $[6] = t2;\n  }\n  return t2;\n}\n```\n\nThe `new Class(...)` inside the loop has no memoization guards because scope @4 was pruned. The `new Class()` outside the loop retains its memoization via scope @5.\n"

    "content": "# flattenScopesWithHooksOrUseHIR\n\n## File\n`src/ReactiveScopes/FlattenScopesWithHooksOrUseHIR.ts`\n\n## Purpose\nThis pass removes (flattens) reactive scopes that transitively contain hook calls or `use()` operator calls. The key insight is that:\n\n1. **Hooks cannot be called conditionally** - wrapping them in a memoized scope would make them conditionally called based on whether the cache is valid\n2. **The `use()` operator** - while it can be called conditionally in source code, React requires it to be called consistently if the component needs the returned value. Memoizing a scope containing `use()` would also make it conditionally called.\n\nBy running reactive scope inference first (agnostic of hooks), the compiler knows which values \"construct together\" in the same scope. The pass then removes ALL memoization for scopes containing hook/use calls to ensure they are always executed unconditionally.\n\n## Input Invariants\n- HIR must have reactive scope terminals already built (pass runs after `BuildReactiveScopeTerminalsHIR`)\n- Blocks are visited in order (the pass iterates through `fn.body.blocks`)\n- Scope terminals have a `block` (body of the scope) and `fallthrough` (block after the scope)\n- Type inference has run so that `getHookKind()` and `isUseOperator()` can identify hooks and use() calls\n\n## Output Guarantees\n- All scopes that transitively contained a hook or `use()` call are either:\n  - Converted to `LabelTerminal` - if the scope body is trivial (just the hook call and a goto)\n  - Converted to `PrunedScopeTerminal` - if the scope body contains other instructions besides the hook call\n- The `PrunedScopeTerminal` still tracks the original scope information for downstream passes but will not generate memoization code\n- The control flow structure is preserved (same blocks, same fallthroughs)\n\n## Algorithm\n\n### Phase 1: Identify Scopes Containing Hook/Use Calls\n1. Maintain a stack `activeScopes` of currently \"open\" reactive scopes\n2. Iterate through all blocks in order\n3. When entering a block:\n   - Remove any scopes from `activeScopes` whose fallthrough equals the current block (those scopes have ended)\n4. For each instruction in the block:\n   - If it's a `CallExpression` or `MethodCall` and the callee is a hook or use operator:\n     - Add all currently active scopes to the `prune` list\n     - Clear `activeScopes` (these scopes are now marked for pruning)\n5. If the block's terminal is a `scope`:\n   - Push it onto `activeScopes`\n\n### Phase 2: Prune Identified Scopes\nFor each block ID in `prune`:\n1. Get the scope terminal\n2. Check if the scope body is trivial (single instruction + goto to fallthrough):\n   - If trivial: Convert to `LabelTerminal` (will be removed by `PruneUnusedLabels`)\n   - If non-trivial: Convert to `PrunedScopeTerminal` (preserves scope info but skips memoization)\n\n## Key Data Structures\n\n```typescript\n// Stack tracking currently open scopes\nactiveScopes: Array<{block: BlockId; fallthrough: BlockId}>\n\n// List of block IDs whose scope terminals should be pruned\nprune: Array<BlockId>\n\n// Terminal types used\nLabelTerminal: {kind: 'label', block, fallthrough, id, loc}\nPrunedScopeTerminal: {kind: 'pruned-scope', block, fallthrough, scope, id, loc}\nReactiveScopeTerminal: {kind: 'scope', block, fallthrough, scope, id, loc}\n```\n\n## Edge Cases\n\n### Nested Scopes\nWhen a hook is found in an inner scope, ALL enclosing scopes are also pruned (the hook call would become conditional if any outer scope were memoized).\n\n### Method Call Hooks\nHandles both `CallExpression` (e.g., `useHook(...)`) and `MethodCall` (e.g., `obj.useHook(...)`).\n\n### Trivial Hook-Only Scopes\nIf a scope exists just for a hook call (single instruction + goto), it's converted to a `LabelTerminal` which is a simpler structure that gets cleaned up by later passes.\n\n### Multiple Hooks in Sequence\nOnce the first hook is encountered, all active scopes are pruned and cleared, so subsequent hooks in outer scopes still work correctly.\n\n## TODOs\nNone explicitly marked in the source file.\n\n## Example\n\n### Fixture: `nested-scopes-hook-call.js`\n\n**Input:**\n```javascript\nfunction component(props) {\n  let x = [];\n  let y = [];\n  y.push(useHook(props.foo));\n  x.push(y);\n  return x;\n}\n```\n\n**Before FlattenScopesWithHooksOrUseHIR:**\n```\nbb0:\n  [1] Scope @0 [1:22] block=bb6 fallthrough=bb7    // Outer scope for x\nbb6:\n  [2] $22 = Array []         // x = []\n  [3] StoreLocal x = $22\n  [4] Scope @1 [4:17] block=bb8 fallthrough=bb9   // Inner scope for y\nbb8:\n  [5] $25 = Array []         // y = []\n  [6] StoreLocal y = $25\n  ...\n  [10] $33 = Call useHook(...)  // <-- Hook call here!\n  [11] MethodCall y.push($33)\n```\n\n**After FlattenScopesWithHooksOrUseHIR:**\n```\nbb0:\n  [1] <pruned> Scope @0 [1:22] block=bb6 fallthrough=bb7   // PRUNED\nbb6:\n  [2] $22 = Array []\n  [3] StoreLocal x = $22\n  [4] <pruned> Scope @1 [4:17] block=bb8 fallthrough=bb9  // PRUNED\nbb8:\n  [5] $25 = Array []\n  [6] StoreLocal y = $25\n  ...\n  [12] Label block=bb10 fallthrough=bb11   // Hook call converted to label\nbb10:\n  [13] $33 = Call useHook(...)\n  [14] Goto bb11\n...\n```\n\n**Final Output (no memoization):**\n```javascript\nfunction component(props) {\n  const x = [];\n  const y = [];\n  y.push(useHook(props.foo));\n  x.push(y);\n  return x;\n}\n```\n\nNotice that:\n1. Both scope @0 and scope @1 are marked as `<pruned>` because the hook call is inside scope @1, which is inside scope @0\n2. The final output has no memoization wrappers - just the raw code\n"

    "content": "# propagateScopeDependenciesHIR\n\n## File\n`src/HIR/PropagateScopeDependenciesHIR.ts`\n\n## Purpose\nThe `propagateScopeDependenciesHIR` pass is responsible for computing and assigning the **dependencies** for each reactive scope in the compiled function. Dependencies are the external values that a scope reads, which determine when the scope needs to re-execute. This is a critical step for memoization correctness - the compiler must track exactly which values a scope depends on so it can generate proper cache invalidation checks.\n\nThe pass also populates:\n- `scope.dependencies` - The set of `ReactiveScopeDependency` objects the scope reads\n- `scope.declarations` - Values declared within the scope that are used outside it\n\n## Input Invariants\n- Reactive scopes must be established (pass runs after `BuildReactiveScopeTerminalsHIR`)\n- The function must be in SSA form\n- `InferMutationAliasingRanges` must have run to establish when values are being mutated\n- `InferReactivePlaces` marks which identifiers are reactive\n- Scope ranges have been aligned and normalized by earlier passes\n\n## Output Guarantees\nAfter this pass completes:\n\n1. Each `ReactiveScope.dependencies` contains the minimal set of dependencies that:\n   - Were declared before the scope started\n   - Are read within the scope\n   - Are not ref values (which are always mutable)\n   - Are not object methods (which get codegen'd back into object literals)\n\n2. Each `ReactiveScope.declarations` contains identifiers that:\n   - Are assigned within the scope\n   - Are used outside the scope (need to be exposed as scope outputs)\n\n3. Property load chains are resolved to their root identifiers with paths (e.g., `props.user.name` becomes `{identifier: props, path: [\"user\", \"name\"]}`)\n\n4. Optional chains are handled correctly, distinguishing between `a?.b` and `a.b` access types\n\n## Algorithm\n\n### Phase 1: Build Sidemaps\n\n1. **findTemporariesUsedOutsideDeclaringScope**: Identifies temporaries that are used outside the scope where they were declared (cannot be hoisted/reordered safely)\n\n2. **collectTemporariesSidemap**: Creates a mapping from temporary IdentifierIds to their source `ReactiveScopeDependency`. For example:\n   ```\n   $0 = LoadLocal 'a'\n   $1 = PropertyLoad $0.'b'\n   ```\n   Maps `$1.id` to `{identifier: a, path: [{property: 'b', optional: false}]}`\n\n3. **collectOptionalChainSidemap**: Traverses optional chain blocks to map temporaries within optional chains to their full optional dependency path\n\n4. **collectHoistablePropertyLoads**: Uses CFG analysis to determine which property loads can be safely hoisted\n\n### Phase 2: Collect Dependencies\n\nThe `collectDependencies` function traverses the HIR, maintaining a stack of active scopes:\n\n1. **Scope Entry/Exit**: When entering a scope terminal, push a new dependency array. When exiting, propagate collected dependencies to parent scopes if valid.\n\n2. **Instruction Processing**: For each instruction:\n   - Declare the lvalue with its instruction id and current scope\n   - Visit operands to record them as potential dependencies\n   - Handle special cases like `StoreLocal` (tracks reassignments), `Destructure`, `PropertyLoad`, etc.\n\n3. **Dependency Validation** (`#checkValidDependency`):\n   - Skip ref values (`isRefValueType`)\n   - Skip object methods (`isObjectMethodType`)\n   - Only include if declared before scope start\n\n### Phase 3: Derive Minimal Dependencies\n\nFor each scope, use `ReactiveScopeDependencyTreeHIR` to:\n1. Build a tree from hoistable property loads\n2. Add all collected dependencies to the tree\n3. Truncate dependencies at their maximal safe-to-evaluate subpath\n4. Derive the minimal set (removing redundant nested dependencies)\n\n## Key Data Structures\n\n### ReactiveScopeDependency\n```typescript\ntype ReactiveScopeDependency = {\n  identifier: Identifier;        // Root identifier\n  reactive: boolean;             // Whether the value is reactive\n  path: DependencyPathEntry[];   // Chain of property accesses\n}\n```\n\n### DependencyPathEntry\n```typescript\ntype DependencyPathEntry = {\n  property: PropertyLiteral;  // Property name\n  optional: boolean;          // Is this `?.` access?\n}\n```\n\n### DependencyCollectionContext\nMaintains:\n- `#declarations`: Map of DeclarationId to {id, scope} recording where each value was declared\n- `#reassignments`: Map of Identifier to latest assignment info\n- `#scopes`: Stack of currently active ReactiveScopes\n- `#dependencies`: Stack of dependency arrays (one per active scope)\n- `#temporaries`: Sidemap for resolving property loads\n\n### ReactiveScopeDependencyTreeHIR\nA tree structure for efficient dependency deduplication that stores hoistable objects, tracks access types, and computes minimal dependencies.\n\n## Edge Cases\n\n### Values Used Outside Declaring Scope\nIf a temporary is used outside its declaring scope, it cannot be tracked in the sidemap because reordering the read would be invalid.\n\n### Ref.current Access\nAccessing `ref.current` is treated specially - the dependency is truncated to just `ref`.\n\n### Optional Chains\nOptional chains like `a?.b?.c` produce different dependency paths than `a.b.c`. The pass distinguishes them and may merge optional loads into unconditional ones when control flow proves the object is non-null.\n\n### Inner Functions\nDependencies from inner functions are collected recursively but with special handling for context variables.\n\n### Phi Nodes\nWhen a value comes from multiple control flow paths, optional chain dependencies from phi operands are also visited.\n\n## TODOs\n1. Line 374-375: `// TODO(mofeiZ): understand optional chaining` - More documentation needed for optional chain handling\n\n## Example\n\n### Fixture: `reactive-control-dependency-if.js`\n\n**Input:**\n```javascript\nfunction Component(props) {\n  let x;\n  if (props.cond) {\n    x = 1;\n  } else {\n    x = 2;\n  }\n  return [x];\n}\n```\n\n**Before PropagateScopeDependenciesHIR:**\n```\nScope scope @0 [12:15] dependencies=[] declarations=[] reassignments=[] block=bb9\n```\n\n**After PropagateScopeDependenciesHIR:**\n```\nScope scope @0 [12:15] dependencies=[x$24:TPrimitive] declarations=[$26_@0] reassignments=[] block=bb9\n```\n\nThe pass identified that:\n- The scope at `[x]` depends on `x$24` (the phi node result from the if/else branches)\n- Even though `x` is assigned to constants (1 or 2), its value depends on the reactive control flow condition `props.cond`\n- The scope declares `$26_@0` (the array output)\n"

This is a critical transformation in the React Compiler pipeline that:\n\n1. **Restores control flow constructs** - Reconstructs `if`, `while`, `for`, `switch`, and other control flow statements from the CFG's basic blocks and terminals\n2. **Eliminates phi nodes** - Replaces SSA phi nodes with compound value expressions (ternaries, logical expressions, sequence expressions)\n3. **Handles labeled break/continue** - Tracks control flow targets to emit explicit labeled `break` and `continue` statements when needed\n4. **Preserves reactive scope information** - Scope terminals are converted to `ReactiveScopeBlock` nodes in the tree\n\n## Input Invariants\n- HIR is in SSA form (variables have been renamed with unique identifiers)\n- Basic blocks are connected (valid predecessor/successor relationships)\n- Each block ends with a valid terminal\n- Phi nodes exist at merge points for values from different control flow paths\n- Reactive scopes have been constructed (`scope` terminals exist)\n- Scope dependencies are computed (`PropagateScopeDependenciesHIR` has run)\n\n## Output Guarantees\n- **Tree structure** - The output is a `ReactiveFunction` with a `body: ReactiveBlock` containing a tree of `ReactiveStatement` nodes\n- **No CFG structure** - Basic blocks are eliminated; control flow is represented through nested reactive terminals\n- **No phi nodes** - Value merges are represented as `ConditionalExpression`, `LogicalExpression`, or `SequenceExpression` values\n- **Labels emitted for all control flow** - Every terminal that can be a break/continue target has a label; unnecessary labels are removed by subsequent `PruneUnusedLabels` pass\n- **Each block emitted exactly once** - A block cannot be generated twice\n- **Scope blocks preserved** - `scope` terminals become `ReactiveScopeBlock` nodes\n\n## Algorithm\n\n### Core Classes\n\n1. **`Driver`** - Traverses blocks and emits ReactiveBlock arrays\n2. **`Context`** - Tracks state:\n   - `emitted: Set<BlockId>` - Which blocks have been generated\n   - `#scheduled: Set<BlockId>` - Blocks that will be emitted by parent constructs\n   - `#controlFlowStack: Array<ControlFlowTarget>` - Stack of active break/continue targets\n   - `scopeFallthroughs: Set<BlockId>` - Fallthroughs for scope blocks\n\n### Traversal Strategy\n\n1.

JavaScript labeled statements are only needed when there is a corresponding `break label` or `continue label` that targets them.\n\n## Input Invariants\n- The input is a `ReactiveFunction` (after conversion from HIR)\n- All `break` and `continue` terminals have:\n  - A `target` (BlockId) indicating which label they jump to\n  - A `targetKind` that is one of: `'implicit'`, `'labeled'`, or `'unlabeled'`\n- Each `ReactiveTerminalStatement` has an optional `label` field containing `id` and `implicit`\n- The pass runs after `assertWellFormedBreakTargets` which validates break/continue targets\n\n## Output Guarantees\n- Labeled terminals where the label is unreachable are flattened into their parent block\n- When flattening, trailing unlabeled `break` statements (that would just fall through) are removed\n- Labels that exist but are never targeted have their `implicit` flag set to `true`\n- Control flow semantics are preserved - only structurally unnecessary labels are removed\n\n## Algorithm\n\nThe pass uses a two-phase approach with a single traversal:\n\n**Phase 1: Collect reachable labels**\n```typescript\nif ((terminal.kind === 'break' || terminal.kind === 'continue') &&\n    terminal.targetKind === 'labeled') {\n  state.add(terminal.target);  // Mark this label as reachable\n}\n```\n\n**Phase 2: Transform terminals**\n```typescript\nconst isReachableLabel = stmt.label !== null && state.has(stmt.label.id);\n\nif (stmt.terminal.kind === 'label' && !isReachableLabel) {\n  // Flatten: extract block contents, removing trailing unlabeled break\n  const block = [...stmt.terminal.block];\n  const last = block.at(-1);\n  if (last?.kind === 'terminal' && last.terminal.kind === 'break' &&\n      last.terminal.target === null) {\n    block.pop();  // Remove trailing break\n  }\n  return {kind: 'replace-many', value: block};\n} else {\n  if (!isReachableLabel && stmt.label != null) {\n    stmt.label.implicit = true;  // Mark as implicit\n  }\n  return {kind: 'keep'};\n}\n```\n\n## Edge Cases\n\n### Trailing Break Removal\nWhen flattening a labeled block, if the last statement is an unlabeled break (`target === null`), it is removed since it would just fall through anyway.\n\n### Implicit vs Labeled Breaks\nOnly breaks with `targetKind === 'labeled'` count toward label reachability. Implicit breaks (fallthrough) and unlabeled breaks don't make a label \"used\".\n\n### Continue Statements\nBoth `break` and `continue` with labeled targets mark the label as reachable.\n\n### Non-Label Terminals with Labels\nOther terminal types (like `if`, `while`, `for`) can also have labels.

A value \"escapes\" in two ways:\n\n1. **Returned from the function** - The value is directly returned or transitively aliased by a return value\n2. **Passed to a hook** - Any value passed as an argument to a hook may be stored by React internally (e.g., the closure passed to `useEffect`)\n\nThe key insight is that values which never escape the component boundary can be safely recreated on each render without affecting the behavior of consumers.\n\n## Input Invariants\n- The input is a `ReactiveFunction` after scope blocks have been identified\n- Reactive scopes have been assigned to instructions\n- The pass runs after `BuildReactiveFunction` and `PruneUnusedLabels`, before `PruneNonReactiveDependencies`\n\n## Output Guarantees\n- **Scopes with non-escaping outputs are removed** - Their instructions are inlined back into the parent scope/function body\n- **Scopes with escaping outputs are retained** - Values that escape via return or hook arguments remain memoized\n- **Transitive dependencies of escaping scopes are preserved** - If an escaping scope depends on a non-escaping value, that value's scope is also retained to prevent unnecessary invalidation\n- **`FinishMemoize` instructions are marked `pruned=true`** - When a scope is pruned, the associated memoization instructions are flagged\n\n## Algorithm\n\n### Phase 1: Build the Dependency Graph\nUsing `CollectDependenciesVisitor`, build:\n- **Identifier nodes** - Each node tracks memoization level, dependencies, scopes, and whether ultimately memoized\n- **Scope nodes** - Each scope tracks its dependencies\n- **Escaping values** - Identifiers that escape via return or hook arguments\n\n### Phase 2: Classify Memoization Levels\nEach instruction value is classified:\n- `Memoized`: Arrays, objects, function calls, `new` expressions - always potentially aliasing\n- `Conditional`: Conditional/logical expressions, property loads - memoized only if dependencies are memoized\n- `Unmemoized`: JSX elements (when `memoizeJsxElements` is false), DeclareLocal\n- `Never`: Primitives, LoadGlobal, binary/unary expressions - can be cheaply compared\n\n### Phase 3: Compute Memoized Identifiers\n`computeMemoizedIdentifiers()` performs a graph traversal starting from escaping values:\n- For each escaping value, recursively visit its dependencies\n- Mark values and their scopes based on memoization level\n- When marking a scope, force-memoize all its dependencies\n\n### Phase 4: Prune Scopes\n`PruneScopesTransform` visits each scope block:\n- If any scope output is in the memoized set, keep the scope\n- If no outputs are memoized, replace the scope block with its inlined instructions\n\n## Edge Cases\n\n### Interleaved Mutations\n```javascript\nconst a = [props.a];  // independently memoizable, non-escaping\nconst b = [];\nconst c = {};\nc.a = a;              // c captures a, but c doesn't escape\nb.push(props.b);      // b escapes via return\nreturn b;\n```\nHere `a` does not directly escape, but it is a dependency of the scope containing `b`. The algorithm correctly identifies that `a`'s scope must be preserved.\n\n### Hook Arguments Escape\nValues passed to hooks are treated as escaping because hooks may store references internally.\n\n### JSX Special Handling\nJSX elements are marked as `Unmemoized` by default because React.memo() can handle dynamic memoization.\n\n### noAlias Functions\nIf a function signature indicates `noAlias === true`, its arguments are not treated as escaping.\n\n### Reassignments\nWhen a scope reassigns a variable, the scope is added as a dependency of that variable.\n\n## TODOs\nNone explicitly in the source file.\n\n## Example\n\n### Fixture: `escape-analysis-non-escaping-interleaved-allocating-dependency.js`\n\n**Input:**\n```javascript\nfunction Component(props) {\n  const a = [props.a];\n\n  const b = [];\n  const c = {};\n  c.a = a;\n  b.push(props.b);\n\n  return b;\n}\n```\n\n**Output:**\n```javascript\nfunction Component(props) {\n  const $ = _c(5);\n  let t0;\n  if ($[0] !== props.a) {\n    t0 = [props.a];\n    $[0] = props.a;\n    $[1] = t0;\n  } else {\n    t0 = $[1];\n  }\n  const a = t0;  // a is memoized even though it doesn't escape directly\n\n  let b;\n  if ($[2] !== a || $[3] !== props.b) {\n    b = [];\n    const c = {};      // c is NOT memoized - it doesn't escape\n    c.a = a;\n    b.push(props.b);\n    $[2] = a;\n    $[3] = props.b;\n    $[4] = b;\n  } else {\n    b = $[4];\n  }\n  return b;\n}\n```\n\nKey observations:\n- `a` is memoized because it's a dependency of the scope containing `b`\n- `c` is not separately memoized because it doesn't escape\n- `b` is memoized because it's returned\n"

    "content": "# pruneNonReactiveDependencies\n\n## File\n`src/ReactiveScopes/PruneNonReactiveDependencies.ts`\n\n## Purpose\nThis pass removes dependencies from reactive scopes that are guaranteed to be **non-reactive** (i.e., their values cannot change between renders). This optimization reduces unnecessary memoization invalidations by ensuring scopes only depend on values that can actually change.\n\nThe pass complements `PropagateScopeDependencies`, which infers dependencies without considering reactivity. This subsequent pruning step filters out dependencies that are semantically constant.\n\n## Input Invariants\n- The function has been converted to a ReactiveFunction structure\n- `InferReactivePlaces` has annotated places with `{reactive: true}` where values can change\n- Each `ReactiveScopeBlock` has a `scope.dependencies` set populated by `PropagateScopeDependenciesHIR`\n- Type inference has run, so identifiers have type information for `isStableType` checks\n\n## Output Guarantees\n- **Non-reactive dependencies removed**: All dependencies in `scope.dependencies` are reactive after this pass\n- **Scope outputs marked reactive if needed**: If a scope has any reactive dependencies remaining, all its outputs are marked reactive\n- **Stable types remain non-reactive through property loads**: When loading properties from stable types (like `useReducer` dispatch functions), the result is not added to the reactive set\n\n## Algorithm\n\n### Phase 1: Collect Reactive Identifiers\nThe `collectReactiveIdentifiers` helper builds the initial set of reactive identifiers by:\n1. Visiting all places in the ReactiveFunction\n2. Adding any place marked `{reactive: true}` to the set\n3. For pruned scopes, adding declarations that are not primitives and not stable ref types\n\n### Phase 2: Propagate Reactivity and Prune Dependencies\nThe main `Visitor` class traverses the ReactiveFunction and:\n\n1. **For Instructions** - Propagates reactivity through data flow:\n   - `LoadLocal`: If source is reactive, mark the lvalue as reactive\n   - `StoreLocal`: If source value is reactive, mark both the local variable and lvalue as reactive\n   - `Destructure`: If source is reactive, mark all pattern operands as reactive (except stable types)\n   - `PropertyLoad`: If object is reactive AND result is not a stable type, mark result as reactive\n   - `ComputedLoad`: If object OR property is reactive, mark result as reactive\n\n2. **For Scopes** - Prunes non-reactive dependencies and propagates outputs:\n   - Delete each dependency from `scope.dependencies` if its identifier is not in the reactive set\n   - If any dependencies remain after pruning, mark all scope outputs as reactive\n\n### Key Insight: Stable Types\nThe pass leverages `isStableType` to prevent reactivity from flowing through certain React-provided stable values:\n\n```typescript\nfunction isStableType(id: Identifier): boolean {\n  return (\n    isSetStateType(id) ||       // useState setter\n    isSetActionStateType(id) || // useActionState setter\n    isDispatcherType(id) ||     // useReducer dispatcher\n    isUseRefType(id) ||         // useRef result\n    isStartTransitionType(id) ||// useTransition startTransition\n    isSetOptimisticType(id)     // useOptimistic setter\n  );\n}\n```\n\n## Edge Cases\n\n### Unmemoized Values Spanning Hook Calls\nA value created before a hook call and mutated after cannot be memoized. However, if it's non-reactive, it still should not appear as a dependency of downstream scopes.\n\n### Stable Types from Reactive Containers\nWhen `useReducer` returns `[state, dispatch]`, `state` is reactive but `dispatch` is stable. The pass correctly handles this.\n\n### Pruned Scopes with Reactive Content\nThe `CollectReactiveIdentifiers` pass also examines pruned scopes and adds their non-primitive, non-stable-ref declarations to the reactive set.\n\n### Transitive Reactivity Through Scopes\nWhen a scope retains at least one reactive dependency, ALL its outputs become reactive.\n\n## TODOs\nNone in the source file.\n\n## Example\n\n### Fixture: `unmemoized-nonreactive-dependency-is-pruned-as-dependency.js`\n\n**Input:**\n```javascript\nfunction Component(props) {\n  const x = [];\n  useNoAlias();\n  mutate(x);\n\n  return <div>{x}</div>;\n}\n```\n\n**Before PruneNonReactiveDependencies:**\n```\nscope @2 dependencies=[x$15_@0:TObject<BuiltInArray>] declarations=[$23_@2]\n```\n\n**After PruneNonReactiveDependencies:**\n```\nscope @2 dependencies=[] declarations=[$23_@2]\n```\n\nThe dependency on `x` is removed because `x` is created locally and therefore non-reactive.\n\n### Fixture: `useReducer-returned-dispatcher-is-non-reactive.js`\n\n**Input:**\n```javascript\nfunction f() {\n  const [state, dispatch] = useReducer();\n\n  const onClick = () => {\n    dispatch();\n  };\n\n  return <div onClick={onClick} />;\n}\n```\n\n**Generated Code:**\n```javascript\nfunction f() {\n  const $ = _c(1);\n  const [, dispatch] = useReducer();\n  let t0;\n  if ($[0] === Symbol.for(\"react.memo_cache_sentinel\")) {\n    const onClick = () => {\n      dispatch();\n    };\n    t0 = <div onClick={onClick} />;\n    $[0] = t0;\n  } else {\n    t0 = $[0];\n  }\n  return t0;\n}\n```\n\nThe `onClick` function only captures `dispatch`, which is a stable type. Therefore, `onClick` is non-reactive, and the JSX element can be memoized with zero dependencies.\n"

    "content": "# pruneUnusedScopes\n\n## File\n`src/ReactiveScopes/PruneUnusedScopes.ts`\n\n## Purpose\nThis pass converts reactive scopes that have no meaningful outputs into \"pruned scopes\". A pruned scope is no longer memoized - its instructions are executed unconditionally on every render. This optimization removes unnecessary memoization overhead for scopes that don't produce values that need to be cached.\n\n## Input Invariants\n- The input is a `ReactiveFunction` that has already been transformed into reactive scope form\n- Scopes have been created and have `declarations`, `reassignments`, and potentially `earlyReturnValue` populated\n- The pass is called after:\n  - `pruneUnusedLabels` - cleans up unnecessary labels\n  - `pruneNonEscapingScopes` - removes scopes whose outputs don't escape\n  - `pruneNonReactiveDependencies` - removes non-reactive dependencies from scopes\n- Scopes may already be marked as pruned by earlier passes\n\n## Output Guarantees\nScopes that meet ALL of the following criteria are converted to `pruned-scope`:\n- No return statement within the scope\n- No reassignments (`scope.reassignments.size === 0`)\n- Either no declarations (`scope.declarations.size === 0`), OR all declarations \"bubbled up\" from inner scopes\n\nPruned scopes:\n- Keep their original scope metadata (for debugging/tracking)\n- Keep their instructions intact\n- Will be executed unconditionally during codegen (no memoization check)\n\n## Algorithm\n\nThe pass uses the visitor pattern with `ReactiveFunctionTransform`:\n\n1. **State Tracking**: A `State` object tracks whether a return statement was encountered:\n   ```typescript\n   type State = {\n     hasReturnStatement: boolean;\n   };\n   ```\n\n2. **Terminal Visitor** (`visitTerminal`): Checks if any terminal is a `return` statement\n\n3. **Scope Transform** (`transformScope`): For each scope:\n   - Creates a fresh state for this scope\n   - Recursively visits the scope's contents\n   - Checks pruning criteria:\n     - `!scopeState.hasReturnStatement` - no early return\n     - `scope.reassignments.size === 0` - no reassignments\n     - `scope.declarations.size === 0` OR `!hasOwnDeclaration(scopeBlock)` - no outputs\n\n4. **hasOwnDeclaration Helper**: Determines if a scope has \"own\" declarations vs declarations propagated from nested scopes\n\n## Edge Cases\n\n### Return Statements\nScopes containing return statements are preserved because early returns need memoization to avoid re-executing the return check on every render.\n\n### Bubbled-Up Declarations\nWhen nested scopes are flattened or merged, their declarations may be propagated to parent scopes. The `hasOwnDeclaration` check ensures that parent scopes with only inherited declarations can still be pruned.\n\n### Reassignments\nScopes with reassignments are kept because the reassignment represents a side effect that needs to be tracked for memoization.\n\n### Already-Pruned Scopes\nThe pass operates on `ReactiveScopeBlock` (kind: 'scope'), not `PrunedReactiveScopeBlock`. Scopes already pruned by earlier passes are not revisited.\n\n### Interaction with Subsequent Passes\nThe `MergeReactiveScopesThatInvalidateTogether` pass explicitly handles pruned scopes - it does not merge across them.\n\n## TODOs\nNone in the source file.\n\n## Example\n\n### Fixture: `prune-scopes-whose-deps-invalidate-array.js`\n\n**Input:**\n```javascript\nfunction Component(props) {\n  const x = [];\n  useHook();\n  x.push(props.value);\n  const y = [x];\n  return [y];\n}\n```\n\nWhat happens:\n- The scope for `x` cannot be memoized because `useHook()` is called inside it\n- `FlattenScopesWithHooksOrUseHIR` marks scope @0 as `pruned-scope`\n- `PruneUnusedScopes` doesn't change it further since it's already pruned\n\n**Output (no memoization for x):**\n```javascript\nfunction Component(props) {\n  const x = [];\n  useHook();\n  x.push(props.value);\n  const y = [x];\n  return [y];\n}\n```\n\n### Key Insight\n\nThe `pruneUnusedScopes` pass is part of a multi-pass pruning strategy:\n1. `FlattenScopesWithHooksOrUseHIR` - Prunes scopes that contain hook/use calls\n2. `pruneNonEscapingScopes` - Prunes scopes whose outputs don't escape\n3. `pruneNonReactiveDependencies` - Removes non-reactive dependencies\n4. **`pruneUnusedScopes`** - Prunes scopes with no remaining outputs\n\nThis pass acts as a cleanup for scopes that became \"empty\" after previous pruning passes removed their outputs.\n"

    "content": "# mergeReactiveScopesThatInvalidateTogether\n\n## File\n`src/ReactiveScopes/MergeReactiveScopesThatInvalidateTogether.ts`\n\n## Purpose\nThis pass is an optimization that reduces memoization overhead in the compiled output by merging reactive scopes that will always invalidate together. The pass operates on the ReactiveFunction representation and works in two main scenarios:\n\n1. **Consecutive Scopes**: When two scopes appear sequentially in the same reactive block with identical dependencies (or where the output of the first scope is the sole input to the second), they are merged into a single scope. This reduces the number of memo cache slots used and eliminates redundant dependency comparisons.\n\n2. **Nested Scopes**: When an inner scope has the same dependencies as its parent scope, the inner scope is flattened into the parent. Since PropagateScopeDependencies propagates dependencies upward, nested scopes can only have equal or fewer dependencies than their parents, never more. When they're equal, the inner scope always invalidates with the parent, making it safe and beneficial to flatten.\n\n## Input Invariants\n- The ReactiveFunction has already undergone scope dependency propagation (via `PropagateScopeDependencies`)\n- The function has been pruned of unused scopes (via `pruneNonReactiveDependencies` and `pruneUnusedScopes`)\n- Scopes have valid `dependencies`, `declarations`, `range`, and `reassignments` fields\n- The ReactiveFunction is in a valid structural state with properly formed blocks and instructions\n\n## Output Guarantees\n- **Fewer scopes**: Consecutive and nested scopes with identical dependencies are merged\n- **Valid scope ranges**: Merged scopes have their `range.end` updated to cover all merged instructions\n- **Updated declarations**: Scope declarations are updated to remove any that are no longer used after the merged scope\n- **Merged scope tracking**: The `scope.merged` set tracks which scope IDs were merged into each surviving scope\n- **Preserved semantics**: Only safe-to-memoize intermediate instructions are absorbed into merged scopes\n\n## Algorithm\n\nThe pass operates in multiple phases:\n\n### Phase 1: Find Last Usage\nA visitor (`FindLastUsageVisitor`) collects the last usage instruction ID for each declaration:\n\n```typescript\nclass FindLastUsageVisitor extends ReactiveFunctionVisitor<void> {\n  lastUsage: Map<DeclarationId, InstructionId> = new Map();\n\n  override visitPlace(id: InstructionId, place: Place, _state: void): void {\n    const previousUsage = this.lastUsage.get(place.identifier.declarationId);\n    const lastUsage =\n      previousUsage !== undefined\n        ? makeInstructionId(Math.max(previousUsage, id))\n        : id;\n    this.lastUsage.set(place.identifier.declarationId, lastUsage);\n  }\n}\n```\n\n### Phase 2: Transform (Nested Scope Flattening)\nThe `transformScope` method flattens nested scopes with identical dependencies:\n\n```typescript\noverride transformScope(\n  scopeBlock: ReactiveScopeBlock,\n  state: ReactiveScopeDependencies | null,\n): Transformed<ReactiveStatement> {\n  this.visitScope(scopeBlock, scopeBlock.scope.dependencies);\n  if (\n    state !== null &&\n    areEqualDependencies(state, scopeBlock.scope.dependencies)\n  ) {\n    return {kind: 'replace-many', value: scopeBlock.instructions};\n  } else {\n    return {kind: 'keep'};\n  }\n}\n```\n\n### Phase 3: Visit Block (Consecutive Scope Merging)\nWithin `visitBlock`, the pass:\n1. First traverses nested blocks recursively\n2. Iterates through instructions, tracking merge candidates\n3. Determines if consecutive scopes can merge based on:\n   - Identical dependencies, OR\n   - Output of first scope is input to second scope (with always-invalidating types)\n4. Collects intermediate lvalues and ensures they're only used by the next scope\n5. Merges eligible scopes by combining instructions and updating range/declarations\n\n### Key Merging Conditions (`canMergeScopes`):\n```typescript\nfunction canMergeScopes(\n  current: ReactiveScopeBlock,\n  next: ReactiveScopeBlock,\n  temporaries: Map<DeclarationId, DeclarationId>,\n): boolean {\n  // Don't merge scopes with reassignments\n  if (current.scope.reassignments.size !== 0 || next.scope.reassignments.size !== 0) {\n    return false;\n  }\n  // Merge scopes whose dependencies are identical\n  if (areEqualDependencies(current.scope.dependencies, next.scope.dependencies)) {\n    return true;\n  }\n  // Merge scopes where outputs of previous are inputs of next\n  // (with always-invalidating type check)\n  // ...\n}\n```\n\n### Always-Invalidating Types:\n```typescript\nexport function isAlwaysInvalidatingType(type: Type): boolean {\n  switch (type.kind) {\n    case 'Object': {\n      switch (type.shapeId) {\n        case BuiltInArrayId:\n        case BuiltInObjectId:\n        case BuiltInFunctionId:\n        case BuiltInJsxId: {\n          return true;\n        }\n      }\n      break;\n    }\n    case 'Function': {\n      return true;\n    }\n  }\n  return false;\n}\n```\n\n## Edge Cases\n\n### Terminals\nThe pass does not merge across terminals (control flow boundaries).\n\n### Pruned Scopes\nMerging stops at pruned scopes.\n\n### Reassignments\nScopes containing reassignments cannot be merged (side-effect ordering concerns).\n\n### Intermediate Reassignments\nNon-const StoreLocal instructions between scopes prevent merging.\n\n### Safe Intermediate Instructions\nOnly certain instruction types are allowed between merged scopes: `BinaryExpression`, `ComputedLoad`, `JSXText`, `LoadGlobal`, `LoadLocal`, `Primitive`, `PropertyLoad`, `TemplateLiteral`, `UnaryExpression`, and const `StoreLocal`.\n\n### Lvalue Usage\nIntermediate values must be last-used at or before the next scope to allow merging.\n\n### Non-Invalidating Outputs\nIf a scope's output may not change when inputs change (e.g., `foo(x) { return x < 10 }` returns same boolean for different x values), that scope cannot be a merge candidate for subsequent scopes.\n\n## TODOs\n```typescript\n/*\n * TODO LeaveSSA: use IdentifierId for more precise tracking\n * Using DeclarationId is necessary for compatible output but produces suboptimal results\n * in cases where a scope defines a variable, but that version is never read and always\n * overwritten later.\n * see reassignment-separate-scopes.js for example\n */\nlastUsage: Map<DeclarationId, InstructionId> = new Map();\n```\n\n## Example\n\n### Fixture: `merge-consecutive-scopes-deps-subset-of-decls.js`\n\n**Input:**\n```javascript\nimport {useState} from 'react';\n\nfunction Component() {\n  const [count, setCount] = useState(0);\n  return (\n    <div>\n      <button onClick={() => setCount(count - 1)}>Decrement</button>\n      <button onClick={() => setCount(count + 1)}>Increment</button>\n    </div>\n  );\n}\n```\n\n**After MergeReactiveScopesThatInvalidateTogether** (from `yarn snap -p merge-consecutive-scopes-deps-subset-of-decls.js -d`):\n```\nscope @1 [7:24] dependencies=[count$32:TPrimitive] declarations=[$51_@5] reassignments=[] {\n  [8] $35_@1 = Function @context[setCount$33, count$32]  // decrement callback\n  [10] $41 = JSXText \"Decrement\"\n  [12] $42_@2 = JSX <button onClick={$35_@1}>{$41}</button>\n  [15] $43_@3 = Function @context[setCount$33, count$32]  // increment callback\n  [17] $49 = JSXText \"Increment\"\n  [19] $50_@4 = JSX <button onClick={$43_@3}>{$49}</button>\n  [22] $51_@5 = JSX <div>{$42_@2}{$50_@4}</div>\n}\n```\n\nAll scopes are merged because they share `count` as a dependency. Without merging, this would have separate scopes for each callback and button element.\n\n**Generated Code:**\n```javascript\nfunction Component() {\n  const $ = _c(2);\n  const [count, setCount] = useState(0);\n  let t0;\n  if ($[0] !== count) {\n    t0 = (\n      <div>\n        <button onClick={() => setCount(count - 1)}>Decrement</button>\n        <button onClick={() => setCount(count + 1)}>Increment</button>\n      </div>\n    );\n    $[0] = count;\n    $[1] = t0;\n  } else {\n    t0 = $[1];\n  }\n  return t0;\n}\n```\n\nThe merged version uses only 2 cache slots instead of potentially 6-8.\n"

    "content": "# pruneAlwaysInvalidatingScopes\n\n## File\n`src/ReactiveScopes/PruneAlwaysInvalidatingScopes.ts`\n\n## Purpose\nThis pass identifies and prunes reactive scopes whose dependencies will *always* invalidate on every render, making memoization pointless. Specifically, it tracks values that are guaranteed to be new allocations (arrays, objects, JSX, new expressions) and checks if those values are used outside of any memoization scope. When a downstream scope depends on such an unmemoized always-invalidating value, the scope is pruned because it would re-execute on every render anyway.\n\nThe optimization avoids wasted comparisons in the generated code. Without this pass, the compiler would emit dependency checks for scopes that will never cache-hit, adding runtime overhead with no benefit. By converting these scopes to `pruned-scope` nodes, the codegen emits the instructions inline without memoization guards.\n\n## Input Invariants\n- The pass expects a `ReactiveFunction` with scopes already formed\n- Scopes should have their `dependencies` populated with the identifiers they depend on\n- The pass runs after `MergeReactiveScopesThatInvalidateTogether`\n- Hook calls have already caused scope flattening via `FlattenScopesWithHooksOrUseHIR`\n\n## Output Guarantees\n- Scopes that depend on unmemoized always-invalidating values are converted to `pruned-scope` nodes\n- The `unmemoizedValues` set correctly propagates through `StoreLocal`/`LoadLocal` instructions\n- All declarations and reassignments within pruned scopes that are themselves always-invalidating are added to `unmemoizedValues`, enabling cascading pruning of downstream scopes\n\n## Algorithm\n\nThe pass uses a `ReactiveFunctionTransform` visitor with two key methods:\n\n### 1. `transformInstruction` - Tracks always-invalidating values:\n\n```typescript\nswitch (value.kind) {\n  case 'ArrayExpression':\n  case 'ObjectExpression':\n  case 'JsxExpression':\n  case 'JsxFragment':\n  case 'NewExpression': {\n    if (lvalue !== null) {\n      this.alwaysInvalidatingValues.add(lvalue.identifier);\n      if (!withinScope) {\n        this.unmemoizedValues.add(lvalue.identifier);  // Key: only if outside a scope\n      }\n    }\n    break;\n  }\n  // Also propagates through StoreLocal and LoadLocal\n}\n```\n\n### 2. `transformScope` - Prunes scopes with unmemoized dependencies:\n\n```typescript\nfor (const dep of scopeBlock.scope.dependencies) {\n  if (this.unmemoizedValues.has(dep.identifier)) {\n    // Propagate unmemoized status to scope outputs\n    for (const [_, decl] of scopeBlock.scope.declarations) {\n      if (this.alwaysInvalidatingValues.has(decl.identifier)) {\n        this.unmemoizedValues.add(decl.identifier);\n      }\n    }\n    return {\n      kind: 'replace',\n      value: {\n        kind: 'pruned-scope',\n        scope: scopeBlock.scope,\n        instructions: scopeBlock.instructions,\n      },\n    };\n  }\n}\n```\n\n## Edge Cases\n\n### Function Calls Not Considered Always-Invalidating\nThe pass optimistically assumes function calls may return primitives, so `makeArray()` doesn't trigger pruning even though it might return a new array.\n\n### Conditional Allocations\nCode like `x = cond ? [] : 42` doesn't trigger pruning because the value might be a primitive.\n\n### Propagation Through Locals\nThe pass correctly tracks values through `StoreLocal` and `LoadLocal` to handle variable reassignments and loads.\n\n### Cascading Pruning\nWhen a scope is pruned, its always-invalidating outputs become unmemoized, potentially causing downstream scopes to be pruned as well.\n\n## TODOs\nNone in the source file.\n\n## Example\n\n### Fixture: `prune-scopes-whose-deps-invalidate-array.js`\n\n**Input:**\n```javascript\nfunction Component(props) {\n  const x = [];\n  useHook();\n  x.push(props.value);\n  const y = [x];\n  return [y];\n}\n```\n\n**After PruneAlwaysInvalidatingScopes** (from `yarn snap -p prune-scopes-whose-deps-invalidate-array.js -d`):\n```\n<pruned> scope @0 [1:14] dependencies=[] declarations=[x$21_@0] reassignments=[] {\n  [2] $20_@0 = Array []\n  [3] StoreLocal Const x$21_@0 = $20_@0\n  [4] $23 = LoadGlobal import { useHook }\n  [6] $24_@1 = Call $23()       // Hook flattens scope\n  [7] break bb9 (implicit)\n  [8] $25_@0 = LoadLocal x$21_@0\n  [9] $26 = PropertyLoad $25_@0.push\n  [10] $27 = LoadLocal props$19\n  [11] $28 = PropertyLoad $27.value\n  [12] $29 = MethodCall $25_@0.$26($28)\n}\n[14] $30 = LoadLocal x$21_@0\n<pruned> scope @2 [15:23] dependencies=[x$21_@0:TObject<BuiltInArray>] declarations=[$35_@3] {\n  [16] $31_@2 = Array [$30]\n  [18] StoreLocal Const y$32 = $31_@2\n  [19] $34 = LoadLocal y$32\n  [21] $35_@3 = Array [$34]\n}\n[23] return $35_@3\n```\n\nKey observations:\n- Scope @0 is pruned because the hook call (`useHook()`) flattens it (hook rules prevent memoization around hooks)\n- `x` is an `ArrayExpression` created in the pruned scope @0, making it unmemoized\n- Scope @2 depends on `x$21_@0` which is unmemoized and always-invalidating (it's an array)\n- Therefore, scope @2 is also pruned - cascading pruning\n\n**Generated Code:**\n```javascript\nfunction Component(props) {\n  const x = [];\n  useHook();\n  x.push(props.value);\n  const y = [x];\n  return [y];\n}\n```\n\nThe output matches the input because all memoization was pruned - the code runs unconditionally on every render.\n"

    "content": "# propagateEarlyReturns\n\n## File\n`src/ReactiveScopes/PropagateEarlyReturns.ts`\n\n## Purpose\nThe `propagateEarlyReturns` pass ensures that reactive scopes (memoization blocks) correctly honor the control flow behavior of the original code, particularly when a function returns early from within a reactive scope. Without this transformation, if a component returned early on the previous render and the inputs have not changed, the cached memoization block would be skipped entirely, but the early return would not occur, causing incorrect behavior.\n\nThe pass solves this by transforming `return` statements inside reactive scopes into assignments to a temporary variable followed by a labeled `break`. After the reactive scope completes, generated code checks whether the early return sentinel value was replaced with an actual return value; if so, the function returns that value.\n\n## Input Invariants\n1. **ReactiveFunction structure**: The input must be a `ReactiveFunction` with scopes already inferred (reactive scope blocks are already established)\n2. **Scope earlyReturnValue not set**: The pass expects `scopeBlock.scope.earlyReturnValue === null` for scopes it processes\n3. **Return statements within reactive scopes**: The pass specifically targets `return` terminal statements that appear within a `withinReactiveScope` context\n\n## Output Guarantees\n1. **Labeled scope blocks**: Top-level reactive scopes containing early returns are wrapped in a labeled block (e.g., `bb14: { ... }`)\n2. **Sentinel initialization**: At the start of each such scope, a temporary variable is initialized to `Symbol.for(\"react.early_return_sentinel\")`\n3. **Return-to-break transformation**: All `return` statements inside the scope are replaced with:\n   - An assignment of the return value to the early return temporary\n   - A `break` to the scope's label\n4. **Early return declaration**: The temporary variable is registered as a declaration of the scope so it gets memoized\n5. **Post-scope check**: During codegen, an if-statement is added after the scope to check if the temporary differs from the sentinel and return it if so\n\n## Algorithm\n\nThe pass uses a visitor pattern with a `ReactiveFunctionTransform` that tracks two pieces of state:\n\n```typescript\ntype State = {\n  withinReactiveScope: boolean;  // Are we inside a reactive scope?\n  earlyReturnValue: ReactiveScope['earlyReturnValue'];  // Bubble up early return info\n};\n```\n\n### Key Steps:\n\n1. **visitScope** - When entering a reactive scope:\n   - Create an inner state with `withinReactiveScope: true`\n   - Traverse the scope's contents\n   - If any early returns were found (`earlyReturnValue !== null`):\n     - If this is the **outermost** scope (parent's `withinReactiveScope` is false):\n       - Store the early return info on the scope\n       - Add the temporary as a scope declaration\n       - Prepend sentinel initialization instructions\n       - Wrap the original instructions in a labeled block\n     - Otherwise, propagate the early return info to the parent scope\n\n2. **transformTerminal** - When encountering a `return` inside a reactive scope:\n   - Create or reuse an early return value identifier\n   - Replace the return with:\n     ```typescript\n     [\n       {kind: 'instruction', /* StoreLocal: reassign earlyReturnValue = returnValue */},\n       {kind: 'terminal', /* break to earlyReturnValue.label */}\n     ]\n     ```\n\n### Sentinel Initialization Code (synthesized at scope start):\n```typescript\n// Load Symbol.for and call it with the sentinel string\nlet t0 = Symbol.for(\"react.early_return_sentinel\");\n```\n\n## Edge Cases\n\n### Nested Reactive Scopes\nWhen early returns occur in nested scopes, only the **outermost** scope gets the labeled block wrapper. Inner scopes bubble their early return information up via `parentState.earlyReturnValue`.\n\n### Multiple Early Returns in Same Scope\nAll returns share the same temporary variable and label. The first return found creates the identifier, subsequent returns reuse it.\n\n### Partial Early Returns\nWhen only some control flow paths return early (e.g., one branch returns, the other falls through), the sentinel check after the scope allows normal execution to continue if no early return occurred.\n\n### Already Processed Scopes\nIf `scopeBlock.scope.earlyReturnValue !== null` on entry, the pass exits early without modification.\n\n### Returns Outside Reactive Scopes\nThe pass only transforms returns where `state.withinReactiveScope === true`. Returns outside scopes are left unchanged.\n\n## TODOs\nNone in the source file.\n\n## Example\n\n### Fixture: `early-return-within-reactive-scope.js`\n\n**Input:**\n```javascript\nfunction Component(props) {\n  let x = [];\n  if (props.cond) {\n    x.push(props.a);\n    return x;\n  } else {\n    return makeArray(props.b);\n  }\n}\n```\n\n**After PropagateEarlyReturns** (from `yarn snap -p early-return-within-reactive-scope.js -d`):\n```\nscope @0 [...] earlyReturn={id: #t34$34, label: 14} {\n  [0] $36 = LoadGlobal(global) Symbol\n  [0] $37 = PropertyLoad $36.for\n  [0] $38 = \"react.early_return_sentinel\"\n  [0] $35 = MethodCall $36.$37($38)\n  [0] StoreLocal Let #t34$34{reactive} = $35    // Initialize sentinel\n  bb14: {\n    [2] $19_@0 = Array []\n    [3] StoreLocal Const x$20_@0 = $19_@0\n    [4] $22{reactive} = LoadLocal props$18\n    [5] $23{reactive} = PropertyLoad $22.cond\n    [6] if ($23) {\n      [7] $24_@0 = LoadLocal x$20_@0\n      [8] $25 = PropertyLoad $24_@0.push\n      [9] $26 = LoadLocal props$18\n      [10] $27 = PropertyLoad $26.a\n      [11] $28 = MethodCall $24_@0.$25($27)\n      [12] $29 = LoadLocal x$20_@0\n      [0] StoreLocal Reassign #t34$34 = $29     // was: return x\n      [0] break bb14 (labeled)\n    } else {\n      [14] $30 = LoadGlobal import { makeArray }\n      [15] $31 = LoadLocal props$18\n      [16] $32 = PropertyLoad $31.b\n      scope @1 [...] {\n        [18] $33_@1 = Call $30($32)\n      }\n      [0] StoreLocal Reassign #t34$34 = $33_@1  // was: return makeArray(props.b)\n      [0] break bb14 (labeled)\n    }\n  }\n}\n```\n\nKey observations:\n- Scope @0 now has `earlyReturn={id: #t34$34, label: 14}`\n- Sentinel initialization code is prepended to the scope\n- The scope body is wrapped in `bb14: { ... }`\n- Both `return x` and `return makeArray(props.b)` are transformed to `StoreLocal Reassign + break bb14`\n\n**Generated Code:**\n```javascript\nfunction Component(props) {\n  const $ = _c(6);\n  let t0;\n  if ($[0] !== props.a || $[1] !== props.b || $[2] !== props.cond) {\n    t0 = Symbol.for(\"react.early_return_sentinel\");\n    bb0: {\n      const x = [];\n      if (props.cond) {\n        x.push(props.a);\n        t0 = x;\n        break bb0;\n      } else {\n        let t1;\n        if ($[4] !== props.b) {\n          t1 = makeArray(props.b);\n          $[4] = props.b;\n          $[5] = t1;\n        } else {\n          t1 = $[5];\n        }\n        t0 = t1;\n        break bb0;\n      }\n    }\n    $[0] = props.a;\n    $[1] = props.b;\n    $[2] = props.cond;\n    $[3] = t0;\n  } else {\n    t0 = $[3];\n  }\n  if (t0 !== Symbol.for(\"react.early_return_sentinel\")) {\n    return t0;\n  }\n}\n```\n\nThis transformation ensures that when inputs don't change, the cached return value is used and returned, preserving referential equality and correct early return behavior.\n"

    "content": "# promoteUsedTemporaries\n\n## File\n`src/ReactiveScopes/PromoteUsedTemporaries.ts`\n\n## Purpose\nThis pass promotes temporary variables (identifiers with no name) to named variables when they need to be referenced across scope boundaries or in code generation. Temporaries are intermediate values that the compiler creates during lowering; they are typically inlined at their use sites during codegen. However, some temporaries must be emitted as separate declarations - this pass identifies and names them.\n\nThe pass ensures that:\n1. Scope dependencies and declarations have proper names for codegen\n2. Variables referenced across reactive scope boundaries are named\n3. JSX tag identifiers get special naming (`T0`, `T1`, etc.)\n4. Temporaries with interposing side-effects are promoted to preserve ordering\n\n## Input Invariants\n- The ReactiveFunction has undergone scope construction and dependency propagation\n- Identifiers may have `name === null` (temporaries) or be named\n- Scopes have `dependencies`, `declarations`, and `reassignments` populated\n- Pruned scopes are properly marked with `kind: 'pruned-scope'`\n\n## Output Guarantees\n- All scope dependencies have non-null names\n- All scope declarations have non-null names\n- JSX tag temporaries use uppercase naming (`T0`, `T1`, ...)\n- Regular temporaries use lowercase naming (`#t{id}`)\n- All instances of a promoted identifier share the same name (via DeclarationId tracking)\n- Temporaries with interposing mutating instructions are promoted to preserve source ordering\n\n## Algorithm\n\nThe pass operates in four phases using visitor classes:\n\n### Phase 1: CollectPromotableTemporaries\nCollects information about which temporaries may need promotion:\n\n```typescript\nclass CollectPromotableTemporaries {\n  // Tracks pruned scope declarations and whether they're used outside their scope\n  pruned: Map<DeclarationId, {activeScopes: Array<ScopeId>; usedOutsideScope: boolean}>\n\n  // Tracks identifiers used as JSX tags (need uppercase names)\n  tags: Set<DeclarationId>\n}\n```\n\n- When visiting a `JsxExpression`, adds the tag identifier to `tags`\n- When visiting a `PrunedScope`, records its declarations\n- Tracks when pruned declarations are used in different scopes\n\n### Phase 2: PromoteTemporaries\nPromotes temporaries that appear in positions requiring names:\n\n```typescript\noverride visitScope(scopeBlock: ReactiveScopeBlock, state: State): void {\n  // Promote all dependencies without names\n  for (const dep of scopeBlock.scope.dependencies) {\n    if (identifier.name == null) {\n      promoteIdentifier(identifier, state);\n    }\n  }\n  // Promote all declarations without names\n  for (const [, declaration] of scopeBlock.scope.declarations) {\n    if (declaration.identifier.name == null) {\n      promoteIdentifier(declaration.identifier, state);\n    }\n  }\n}\n```\n\nAlso promotes:\n- Function parameters without names\n- Pruned scope declarations used outside their scope\n\n### Phase 3: PromoteInterposedTemporaries\nHandles ordering-sensitive promotion:\n\n```typescript\nclass PromoteInterposedTemporaries {\n  // Instructions that emit as statements can interpose between temp defs and uses\n  // If such an instruction occurs, mark pending temporaries as needing promotion\n\n  override visitInstruction(instruction: ReactiveInstruction, state: InterState): void {\n    // For instructions that become statements (calls, stores, etc.):\n    if (willBeStatement && !constStore) {\n      // Mark all pending temporaries as needing promotion\n      for (const [key, [ident, _]] of state.entries()) {\n        state.set(key, [ident, true]);  // Mark as needing promotion\n      }\n    }\n  }\n}\n```\n\nThis preserves source ordering when side-effects occur between a temporary's definition and use.\n\n### Phase 4: PromoteAllInstancesOfPromotedTemporaries\nEnsures all instances of a promoted identifier share the same name:\n\n```typescript\nclass PromoteAllInstancesOfPromotedTemporaries {\n  override visitPlace(_id: InstructionId, place: Place, state: State): void {\n    if (place.identifier.name === null &&\n        state.promoted.has(place.identifier.declarationId)) {\n      promoteIdentifier(place.identifier, state);\n    }\n  }\n}\n```\n\n### Naming Convention\n```typescript\nfunction promoteIdentifier(identifier: Identifier, state: State): void {\n  if (state.tags.has(identifier.declarationId)) {\n    promoteTemporaryJsxTag(identifier);  // Uses #T{id} for JSX tags\n  } else {\n    promoteTemporary(identifier);  // Uses #t{id} for regular temps\n  }\n  state.promoted.add(identifier.declarationId);\n}\n```\n\n## Edge Cases\n\n### JSX Tag Temporaries\nJSX tags require uppercase names to be valid JSX syntax. The pass tracks which temporaries are used as JSX tags and uses `T0`, `T1`, etc. instead of `t0`, `t1`.\n\n### Pruned Scope Declarations\nDeclarations in pruned scopes are only promoted if they're actually used outside the pruned scope, avoiding unnecessary variable declarations.\n\n### Const vs Let Temporaries\nThe pass tracks const identifiers specially - they don't need promotion for ordering purposes since they can't be mutated by interposing instructions.\n\n### Global Loads\nValues loaded from globals (and their property loads) are treated as const-like for promotion purposes.\n\n### Method Call Properties\nThe property identifier in a method call is treated as const-like to avoid unnecessary promotion.\n\n## TODOs\nNone in the source file.\n\n## Example\n\n### Fixture: `simple.js`\n\n**Input:**\n```javascript\nexport default function foo(x, y) {\n  if (x) {\n    return foo(false, y);\n  }\n  return [y * 10];\n}\n```\n\n**Before PromoteUsedTemporaries:**\n```\nscope @0 [...] dependencies=[y$14] declarations=[$19_@0]\nscope @1 [...] dependencies=[$22] declarations=[$23_@1]\n```\n\n**After PromoteUsedTemporaries:**\n```\nscope @0 [...] dependencies=[y$14] declarations=[#t5$19_@0]\nscope @1 [...] dependencies=[#t9$22] declarations=[#t10$23_@1]\n```\n\nKey observations:\n- `$19_@0` is promoted to `#t5$19_@0` because it's a scope declaration\n- `$22` is promoted to `#t9$22` because it's a scope dependency\n- `$23_@1` is promoted to `#t10$23_@1` because it's a scope declaration\n- The `#t` prefix indicates this is a promoted temporary (later renamed by `renameVariables`)\n\n**Generated Code:**\n```javascript\nimport { c as _c } from \"react/compiler-runtime\";\nexport default function foo(x, y) {\n  const $ = _c(4);\n  if (x) {\n    let t0;\n    if ($[0] !== y) {\n      t0 = foo(false, y);\n      $[0] = y;\n      $[1] = t0;\n    } else {\n      t0 = $[1];\n    }\n    return t0;\n  }\n  const t0 = y * 10;\n  let t1;\n  if ($[2] !== t0) {\n    t1 = [t0];\n    $[2] = t0;\n    $[3] = t1;\n  } else {\n    t1 = $[3];\n  }\n  return t1;\n}\n```\n\nThe promoted temporaries (`#t5`, `#t9`, `#t10`) become the named variables (`t0`, `t1`) in the output after `renameVariables` runs.\n"

    "content": "# codegenReactiveFunction\n\n## File\n`src/ReactiveScopes/CodegenReactiveFunction.ts`\n\n## Purpose\nThis is the final pass that converts the ReactiveFunction representation back into a Babel AST. It generates the memoization code that makes React components and hooks efficient by:\n1. Creating the `useMemoCache` call to allocate cache slots\n2. Generating dependency comparisons to check if values have changed\n3. Emitting conditional blocks that skip computation when cached values are valid\n4. Storing computed values in the cache\n5. Loading cached values when dependencies haven't changed\n\n## Input Invariants\n- The ReactiveFunction has been through all prior passes\n- All identifiers that need names have been promoted and renamed\n- Reactive scopes have finalized `dependencies`, `declarations`, and `reassignments`\n- Early returns have been transformed with sentinel values (via `propagateEarlyReturns`)\n- Pruned scopes are marked with `kind: 'pruned-scope'`\n- Unique identifiers set is available to avoid naming conflicts\n\n## Output Guarantees\n- Returns a `CodegenFunction` with Babel AST `body`\n- All reactive scopes become if-else blocks checking dependencies\n- The `$` cache array is properly sized with `useMemoCache(n)`\n- Each dependency and output gets its own cache slot\n- Pruned scopes emit their instructions inline without memoization\n- Early returns use the sentinel pattern with post-scope checks\n- Statistics are collected: `memoSlotsUsed`, `memoBlocks`, `memoValues`, etc.\n\n## Algorithm\n\n### Entry Point: codegenFunction\n```typescript\nexport function codegenFunction(fn: ReactiveFunction): Result<CodegenFunction, CompilerError> {\n  const cx = new Context(...);\n\n  // Optional: Fast Refresh source hash tracking\n  if (enableResetCacheOnSourceFileChanges) {\n    fastRefreshState = { cacheIndex: cx.nextCacheIndex, hash: sha256(source) };\n  }\n\n  const compiled = codegenReactiveFunction(cx, fn);\n\n  // Prepend useMemoCache call if any cache slots used\n  if (cacheCount !== 0) {\n    body.unshift(\n      t.variableDeclaration('const', [\n        t.variableDeclarator(\n          t.identifier('$'),\n          t.callExpression(t.identifier('useMemoCache'), [t.numericLiteral(cacheCount)])\n        )\n      ])\n    );\n  }\n\n  return compiled;\n}\n```\n\n### Context Class\nTracks state during codegen:\n```typescript\nclass Context {\n  #nextCacheIndex: number = 0;  // Allocates cache slots\n  #declarations: Set<DeclarationId> = new Set();  // Tracks declared variables\n  temp: Temporaries;  // Maps identifiers to their expressions\n  errors: CompilerError;\n\n  get nextCacheIndex(): number {\n    return this.#nextCacheIndex++;  // Returns and increments\n  }\n}\n```\n\n### codegenReactiveScope\nThe core of memoization code generation:\n\n```typescript\nfunction codegenReactiveScope(cx: Context, statements: Array<t.Statement>,\n                              scope: ReactiveScope, block: ReactiveBlock): void {\n  const changeExpressions: Array<t.Expression> = [];\n  const cacheStoreStatements: Array<t.Statement> = [];\n  const cacheLoadStatements: Array<t.Statement> = [];\n\n  // 1. Generate dependency checks\n  for (const dep of scope.dependencies) {\n    const index = cx.nextCacheIndex;\n    changeExpressions.push(\n      t.binaryExpression('!==',\n        t.memberExpression(t.identifier('$'), t.numericLiteral(index), true),\n        codegenDependency(cx, dep)\n      )\n    );\n    cacheStoreStatements.push(\n      t.assignmentExpression('=', $[index], dep)\n    );\n  }\n\n  // 2. Generate output cache slots\n  for (const {identifier} of scope.declarations) {\n    const index = cx.nextCacheIndex;\n    // Declare variable if not already declared\n    if (!cx.hasDeclared(identifier)) {\n      statements.push(t.variableDeclaration('let', [t.variableDeclarator(name, null)]));\n    }\n    cacheLoads.push({name, index, value: name});\n  }\n\n  // 3. Build test condition\n  let testCondition = changeExpressions.reduce((acc, expr) =>\n    t.logicalExpression('||', acc, expr)\n  );\n\n  // 4. If no dependencies, use sentinel check\n  if (testCondition === null) {\n    testCondition = t.binaryExpression('===',\n      $[firstOutputIndex],\n      t.callExpression(Symbol.for, ['react.memo_cache_sentinel'])\n    );\n  }\n\n  // 5. Generate the memoization if-else\n  statements.push(\n    t.ifStatement(\n      testCondition,\n      computationBlock,  // Compute + store in cache\n      cacheLoadBlock     // Load from cache\n    )\n  );\n}\n```\n\n### Generated Structure\nFor a scope with dependencies `[a, b]` and output `result`:\n\n```javascript\nlet result;\nif ($[0] !== a || $[1] !== b) {\n  // Computation block\n  result = compute(a, b);\n\n  // Store dependencies\n  $[0] = a;\n  $[1] = b;\n\n  // Store output\n  $[2] = result;\n} else {\n  // Load from cache\n  result = $[2];\n}\n```\n\n### Early Return Handling\nWhen a scope has an early return (from `propagateEarlyReturns`):\n\n```typescript\n// Before scope: initialize sentinel\nt0 = Symbol.for(\"react.early_return_sentinel\");\n\n// Scope generates labeled block\nbb0: {\n  // ... computation ...\n  if (cond) {\n    t0 = returnValue;\n    break bb0;\n  }\n}\n\n// After scope: check for early return\nif (t0 !== Symbol.for(\"react.early_return_sentinel\")) {\n  return t0;\n}\n```\n\n### Pruned Scopes\nPruned scopes emit their instructions inline without memoization:\n```typescript\ncase 'pruned-scope': {\n  const scopeBlock = codegenBlockNoReset(cx, item.instructions);\n  statements.push(...scopeBlock.body);  // Inline, no memoization\n  break;\n}\n```\n\n## Edge Cases\n\n### Zero Dependencies\nScopes with no dependencies use a sentinel value check instead:\n```javascript\nif ($[0] === Symbol.for(\"react.memo_cache_sentinel\")) {\n  // First render only\n}\n```\n\n### Fast Refresh / HMR\nWhen `enableResetCacheOnSourceFileChanges` is enabled, the generated code includes a source hash check that resets the cache when the source changes:\n```javascript\nif ($[0] !== \"source_hash_abc123\") {\n  for (let $i = 0; $i < cacheCount; $i++) {\n    $[$i] = Symbol.for(\"react.memo_cache_sentinel\");\n  }\n  $[0] = \"source_hash_abc123\";\n}\n```\n\n\n### Labeled Breaks\nControl flow with labeled breaks (for early returns or loop exits) uses `codegenLabel` to generate consistent label names:\n```typescript\nfunction codegenLabel(id: BlockId): string {\n  return `bb${id}`;  // e.g., \"bb0\", \"bb1\"\n}\n```\n\n### Nested Functions\nFunction expressions and object methods are recursively processed with their own contexts.\n\n### FBT/Internationalization\nSpecial handling for FBT operands ensures they're memoized in the same scope for correct internationalization behavior.\n\n## Statistics Collected\n```typescript\ntype CodegenFunction = {\n  memoSlotsUsed: number;     // Total cache slots allocated\n  memoBlocks: number;        // Number of reactive scopes\n  memoValues: number;        // Total memoized values\n  prunedMemoBlocks: number;  // Scopes that were pruned\n  prunedMemoValues: number;  // Values in pruned scopes\n  hasInferredEffect: boolean;\n};\n```\n\n## TODOs\nNone in the source file.\n\n## Example\n\n### Fixture: `simple.js`\n\n**Input:**\n```javascript\nexport default function foo(x, y) {\n  if (x) {\n    return foo(false, y);\n  }\n  return [y * 10];\n}\n```\n\n**Generated Code:**\n```javascript\nimport { c as _c } from \"react/compiler-runtime\";\nexport default function foo(x, y) {\n  const $ = _c(4);  // Allocate 4 cache slots\n  if (x) {\n    let t0;\n    if ($[0] !== y) {           // Check dependency\n      t0 = foo(false, y);       // Compute\n      $[0] = y;                 // Store dependency\n      $[1] = t0;                // Store output\n    } else {\n      t0 = $[1];                // Load from cache\n    }\n    return t0;\n  }\n  const t0 = y * 10;\n  let t1;\n  if ($[2] !== t0) {            // Check dependency\n    t1 = [t0];                  // Compute\n    $[2] = t0;                  // Store dependency\n    $[3] = t1;                  // Store output\n  } else {\n    t1 = $[3];                  // Load from cache\n  }\n  return t1;\n}\n```\n\nKey observations:\n- `_c(4)` allocates 4 cache slots total\n- First scope uses slots 0-1: slot 0 for `y` dependency, slot 1 for `t0` output\n- Second scope uses slots 2-3: slot 2 for `t0` (the computed `y * 10`), slot 3 for `t1` (the array)\n- Each scope has an if-else structure: compute/store vs load\n- The memoization ensures referential equality of the returned array when `y` hasn't changed\n"

    "content": "# optimizePropsMethodCalls\n\n## File\n`src/Optimization/OptimizePropsMethodCalls.ts`\n\n## Purpose\nThis pass converts method calls on the props object to regular function calls. Method calls like `props.onClick()` are transformed to `const t0 = props.onClick; t0()`. This normalization enables better analysis and optimization by the compiler.\n\nThe transformation is important because method calls have different semantics than regular calls - the receiver (`props`) would normally be passed as `this` to the method. For React props, methods are typically just callback functions where `this` binding doesn't matter, so converting them to regular calls is safe and enables better memoization.\n\n## Input Invariants\n- The function has been through type inference\n- Props parameters are typed as `TObject<BuiltInProps>`\n\n## Output Guarantees\n- All `MethodCall` instructions where the receiver has props type are converted to `CallExpression`\n- The method property becomes the callee of the call\n- Arguments are preserved exactly\n\n## Algorithm\n\n```typescript\nexport function optimizePropsMethodCalls(fn: HIRFunction): void {\n  for (const [, block] of fn.body.blocks) {\n    for (let i = 0; i < block.instructions.length; i++) {\n      const instr = block.instructions[i]!;\n\n      if (\n        instr.value.kind === 'MethodCall' &&\n        isPropsType(instr.value.receiver.identifier)\n      ) {\n        // Transform: props.onClick(arg)\n        // To: const t0 = props.onClick; t0(arg)\n        instr.value = {\n          kind: 'CallExpression',\n          callee: instr.value.property,  // The method becomes the callee\n          args: instr.value.args,\n          loc: instr.value.loc,\n        };\n      }\n    }\n  }\n}\n\nfunction isPropsType(identifier: Identifier): boolean {\n  return (\n    identifier.type.kind === 'Object' &&\n    identifier.type.shapeId === BuiltInPropsId\n  );\n}\n```\n\n## Edge Cases\n\n### Non-Props Method Calls\nMethod calls on non-props objects are left unchanged:\n```javascript\n// Unchanged - array.map is not on props\narray.map(x => x * 2)\n\n// Unchanged - obj is not props\nobj.method()\n```\n\n### Props Type Detection\nThe pass uses type information to identify props:\n```javascript\nfunction Component(props) {\n  // props has type TObject<BuiltInProps>\n  props.onClick();  // Transformed\n}\n\nfunction Regular(obj) {\n  // obj has unknown type\n  obj.onClick();  // Not transformed\n}\n```\n\n### Nested Props Access\nOnly direct method calls on props are transformed:\n```javascript\nprops.onClick();       // Transformed\nprops.nested.onClick(); // Not transformed (receiver is props.nested, not props)\n```\n\n### Arrow Function Callbacks\nWorks with any method on props:\n```javascript\nprops.onChange(value);   // Transformed\nprops.onSubmit(data);    // Transformed\nprops.validate(input);   // Transformed\n```\n\n## TODOs\nNone in the source file.\n\n## Example\n\n### Fixture: Using props method\n\n**Input:**\n```javascript\nfunction Component(props) {\n  return <button onClick={() => props.onClick()} />;\n}\n```\n\n**Before OptimizePropsMethodCalls:**\n```\n[1] $5 = Function @context[props$1] ...\n    <<anonymous>>():\n      [1] $2 = LoadLocal props$1\n      [2] $3 = PropertyLoad $2.onClick\n      [3] $4 = MethodCall $2.$3()  // Method call on props\n      [4] Return Void\n```\n\n**After OptimizePropsMethodCalls:**\n```\n[1] $5 = Function @context[props$1] ...\n    <<anonymous>>():\n      [1] $2 = LoadLocal props$1\n      [2] $3 = PropertyLoad $2.onClick\n      [3] $4 = Call $3()  // Now a regular call\n      [4] Return Void\n```\n\nKey observations:\n- `MethodCall $2.$3()` becomes `Call $3()`\n- The property load (`$3 = PropertyLoad $2.onClick`) is preserved\n- The receiver (`$2`) is no longer part of the call\n- This enables the compiler to analyze `onClick` as a regular function\n"

    "content": "# optimizeForSSR\n\n## File\n`src/Optimization/OptimizeForSSR.ts`\n\n## Purpose\nThis pass applies Server-Side Rendering (SSR) specific optimizations. During SSR, React renders components to HTML strings without mounting them in the DOM. This means:\n\n1. **Effects don't run** - `useEffect` and `useLayoutEffect` are no-ops\n2. **Event handlers aren't needed** - There's no DOM to attach handlers to\n3. **State is never updated** - Components render once with initial state\n4. **Refs aren't attached** - There's no DOM to ref\n\nThe pass leverages these SSR characteristics to inline and simplify code, removing unnecessary runtime overhead.\n\n## Input Invariants\n- The function has been through type inference\n- Hook types are properly identified (useState, useReducer, useEffect, etc.)\n- Function types for callbacks are properly inferred\n\n## Output Guarantees\n- `useState(initialValue)` is inlined to just `[initialValue, noop]`\n- `useReducer(reducer, initialArg, init?)` is inlined to `[init ? init(initialArg) : initialArg, noop]`\n- `useEffect` and `useLayoutEffect` calls are removed entirely\n- Event handler functions (functions that call setState) are replaced with empty functions\n- Ref-typed values are removed from JSX props\n\n## Algorithm\n\n### Phase 1: Identify Inlinable State\n```typescript\nconst inlinedState = new Map<IdentifierId, InstructionValue>();\n\nfor (const instr of block.instructions) {\n  if (isUseStateCall(instr)) {\n    // Store the initial value for inlining\n    inlinedState.set(instr.lvalue.id, {\n      kind: 'ArrayExpression',\n      elements: [initialValue, noopFunction],\n    });\n  }\n\n  if (isUseReducerCall(instr)) {\n    // Compute initial state and store for inlining\n    const initialState = init ? callInit(initialArg) : initialArg;\n    inlinedState.set(instr.lvalue.id, {\n      kind: 'ArrayExpression',\n      elements: [initialState, noopFunction],\n    });\n  }\n}\n```\n\n### Phase 2: Inline State Hooks\nReplace useState/useReducer with their computed initial values:\n```typescript\n// Before:\n$0 = useState(0)\n[state, setState] = $0\n\n// After (inlined):\n$0 = [0, () => {}]\n[state, setState] = $0\n```\n\n### Phase 3: Remove Effects\n```typescript\nif (isUseEffectCall(instr) || isUseLayoutEffectCall(instr)) {\n  // Remove the instruction entirely\n  block.instructions.splice(i, 1);\n}\n```\n\n### Phase 4: Identify and Neuter Event Handlers\n```typescript\n// Functions that capture and call setState are event handlers\nif (capturesSetState(functionExpr)) {\n  // Replace with empty function\n  instr.value = {\n    kind: 'FunctionExpression',\n    params: originalParams,\n    body: emptyBody,\n  };\n}\n```\n\n### Phase 5: Remove Ref Props\n```typescript\nif (isJSX(instr) && hasRefProp(instr)) {\n  // Remove ref={...} from JSX props\n  removeRefProp(instr.value);\n}\n```\n\n## Edge Cases\n\n### useState with Function Initializer\nWhen `useState` receives a function initializer, it must be called:\n```javascript\n// useState(() => expensive())\n// SSR: Call the initializer to get the value\nconst [state] = [expensiveComputation(), noop];\n```\n\n### useReducer with Init Function\nThe optional `init` function is called with `initialArg`:\n```javascript\n// useReducer(reducer, arg, init)\n// SSR: [init(arg), noop]\n```\n\n### Nested State Setters\nFunctions that transitively call setState are also event handlers:\n```javascript\nfunction outer() {\n  function inner() {\n    setState(x);  // inner is event handler\n  }\n  inner();  // outer is also event handler\n}\n```\n\n### Conditional Event Handlers\nEvent handler detection is conservative - if a function might call setState, it's treated as an event handler.\n\n### Refs in Nested Objects\nOnly direct `ref` props on JSX are removed:\n```javascript\n<div ref={myRef} />           // ref removed\n<div config={{ref: myRef}} /> // ref NOT removed (nested)\n```\n\n## TODOs\nNone in the source file.\n\n## Example\n\n### Fixture: `ssr/optimize-ssr.js`\n\n**Input:**\n```javascript\nfunction Component() {\n  const [state, setState] = useState(0);\n  const ref = useRef(null);\n  const onChange = (e) => {\n    setState(e.target.value);\n  };\n  useEffect(() => {\n    log(ref.current.value);\n  });\n  return <input value={state} onChange={onChange} ref={ref} />;\n}\n```\n\n**After SSR Optimization:**\n```javascript\nfunction Component() {\n  const $ = _c(1);\n  // useState inlined to [initialValue, noop]\n  const [state] = [0, () => {}];\n\n  // useRef returns object with current: null\n  const ref = { current: null };\n\n  // Event handler replaced with noop (it calls setState)\n  const onChange = () => {};\n\n  // useEffect removed entirely (no-op on SSR)\n\n  // ref prop removed from JSX\n  let t0;\n  if ($[0] === Symbol.for(\"react.memo_cache_sentinel\")) {\n    t0 = <input value={state} onChange={onChange} />;\n    $[0] = t0;\n  } else {\n    t0 = $[0];\n  }\n  return t0;\n}\n```\n\nKey observations:\n- `useState(0)` becomes `[0, () => {}]` - no hook call\n- `useEffect(...)` is removed entirely\n- `onChange` is replaced with empty function since it called `setState`\n- `ref={ref}` prop is removed from JSX\n- SSR output is simpler and has less runtime overhead\n"

Such functions don't need to be recreated on each render and can be hoisted to module scope.\n\n## Input Invariants\n- The `enableFunctionOutlining` feature flag must be enabled\n- Functions must have `context.length === 0` (no captured variables)\n- Functions must be anonymous (no `id` property)\n- Functions must not be FBT macro operands (tracked by `fbtOperands` parameter)\n\n## Output Guarantees\n- Pure function expressions are replaced with `LoadGlobal` of the outlined function\n- Outlined functions are registered with the environment for emission\n- The original instruction is transformed to load the global\n\n## Algorithm\n\n```typescript\nexport function outlineFunctions(\n  fn: HIRFunction,\n  fbtOperands: Set<IdentifierId>,\n): void {\n  for (const [, block] of fn.body.blocks) {\n    for (let i = 0; i < block.instructions.length; i++) {\n      const instr = block.instructions[i]!;\n\n      if (\n        instr.value.kind === 'FunctionExpression' &&\n        instr.value.loweredFunc.func.context.length === 0 &&\n        instr.value.loweredFunc.func.id === null &&\n        !fbtOperands.has(instr.lvalue.identifier.id)\n      ) {\n        // Outline this function\n        const outlinedId = fn.env.outlineFunction(\n          instr.value.loweredFunc.func,\n          'helper',\n        );\n\n        // Replace with LoadGlobal\n        instr.value = {\n          kind: 'LoadGlobal',\n          binding: {\n            kind: 'ModuleLocal',\n            name: outlinedId,\n          },\n          loc: instr.value.loc,\n        };\n      }\n    }\n  }\n}\n```\n\n## Edge Cases\n\n### Functions with Context\nFunctions that capture variables are not outlined:\n```javascript\nfunction Component(props) {\n  const x = props.value;\n  const fn = () => x * 2;  // Captures x, not outlined\n}\n```\n\n### Named Functions\nFunctions with explicit names are not outlined:\n```javascript\nconst foo = function namedFn() { ... };  // Has id, not outlined\n```\n\n### FBT Operands\nFunctions used as FBT operands cannot be outlined due to translation requirements:\n```javascript\n<fbt>\n  Hello <fbt:param name=\"user\">{() => getName()}</fbt:param>\n</fbt>\n// The function cannot be outlined - FBT needs it inline\n```\n\n### Arrow Functions vs Function Expressions\nBoth arrow functions and function expressions are candidates:\n```javascript\nconst a = () => 1;           // Outlined if no context\nconst b = function() {};     // Outlined if no context\n```\n\n### Recursive Functions\nSelf-referencing functions cannot be outlined (they would have themselves in context):\n```javascript\nconst fib = (n) => n <= 1 ? n : fib(n-1) + fib(n-2);  // References self\n```\n\n## TODOs\nNone in the source file.\n\n## Example\n\n### Fixture: `outlined-helper.js`\n\n**Input:**\n```javascript\n// @enableFunctionOutlining\nfunction Component(props) {\n  return (\n    <div>\n      {props.items.map(item => (\n        <Stringify key={item.id} item={item.name} />\n      ))}\n    </div>\n  );\n}\n```\n\n**Analysis:**\nThe map callback `item => <Stringify .../>` has one captured variable: nothing from the component (only uses `item` parameter). However, it receives `item` as a parameter, not from context.\n\nIf we have a truly pure helper:\n```javascript\n// @enableFunctionOutlining\nfunction Component(props) {\n  const double = (x) => x * 2;  // No context, pure\n  return <div>{double(props.value)}</div>;\n}\n```\n\n**After OutlineFunctions:**\n```\n// Outlined to module scope:\nfunction _outlined_double$1(x) {\n  return x * 2;\n}\n\n// In component:\n[1] $1 = LoadGlobal _outlined_double$1  // Instead of FunctionExpression\n[2] StoreLocal Const double = $1\n```\n\n**Generated Code:**\n```javascript\nfunction _outlined_double$1(x) {\n  return x * 2;\n}\n\nfunction Component(props) {\n  const $ = _c(2);\n  const double = _outlined_double$1;  // Just a reference, no recreation\n  let t0;\n  if ($[0] !== props.value) {\n    t0 = <div>{double(props.value)}</div>;\n    $[0] = props.value;\n    $[1] = t0;\n  } else {\n    t0 = $[1];\n  }\n  return t0;\n}\n```\n\nKey observations:\n- The pure function is hoisted to module scope\n- The component just references the outlined function\n- No memoization needed for the function itself\n- Reduces runtime overhead by avoiding function recreation\n"

    "content": "# memoizeFbtAndMacroOperandsInSameScope\n\n## File\n`src/ReactiveScopes/MemoizeFbtAndMacroOperandsInSameScope.ts`\n\n## Purpose\nThis pass ensures that FBT (Facebook Translation) expressions and their operands are memoized within the same reactive scope. FBT is Facebook's internationalization system that requires special handling to ensure translations work correctly.\n\nThe key insight is that FBT operands must be computed and frozen together with the FBT call itself. If operands were memoized in separate scopes, the translation system could receive stale operand values when only some inputs change.\n\n## Input Invariants\n- The function has been through type inference\n- FBT calls (`fbt`, `fbt.c`, `fbt:param`, etc.) are properly identified\n- Custom macros are configured in `fn.env.config.customMacros`\n- Reactive scope variables have been inferred\n\n## Output Guarantees\n- All operands of FBT calls are assigned to the same reactive scope as the FBT call\n- The `fbtOperands` set is returned for use by other passes (e.g., `outlineFunctions`)\n- Operand scope assignments use either transitive or shallow inlining based on macro definition\n\n## Algorithm\n\n### Phase 1: Collect Macro Kinds\n```typescript\nconst macroKinds = new Map<Macro, MacroDefinition>([\n  ...Array.from(FBT_TAGS.entries()),  // Built-in fbt tags\n  ...(fn.env.config.customMacros ?? []).map(([name, def]) => [name, def]),\n]);\n```\n\n### Phase 2: Populate Macro Tags\n```typescript\nfunction populateMacroTags(\n  fn: HIRFunction,\n  macroKinds: Map<Macro, MacroDefinition>,\n): Map<IdentifierId, MacroDefinition> {\n  const macroTags = new Map();\n\n  for (const instr of allInstructions(fn)) {\n    if (isLoadGlobal(instr) || isPropertyLoad(instr)) {\n      const name = getName(instr);\n      if (macroKinds.has(name)) {\n        macroTags.set(instr.lvalue.id, macroKinds.get(name));\n      }\n    }\n  }\n\n  return macroTags;\n}\n```\n\n### Phase 3: Merge Macro Arguments\n```typescript\nfunction mergeMacroArguments(\n  fn: HIRFunction,\n  macroTags: Map<IdentifierId, MacroDefinition>,\n  macroKinds: Map<Macro, MacroDefinition>,\n): Set<IdentifierId> {\n  const macroValues = new Set<IdentifierId>();\n\n  for (const instr of allInstructions(fn)) {\n    if (isCall(instr) || isMethodCall(instr) || isJSX(instr)) {\n      const callee = getCallee(instr);\n      const macroDef = macroTags.get(callee.id);\n\n      if (macroDef !== undefined) {\n        // Mark all operands to be in same scope\n        for (const operand of getOperands(instr)) {\n          macroValues.add(operand.id);\n\n          // Merge scope to match macro call scope\n          if (macroDef.inlineLevel === InlineLevel.Transitive) {\n            mergeScopesTransitively(operand, instr.lvalue);\n          } else {\n            mergeScopes(operand, instr.lvalue);\n          }\n        }\n      }\n    }\n  }\n\n  return macroValues;\n}\n```\n\n### InlineLevel Types\n```typescript\nenum InlineLevel {\n  Shallow,     // Only merge direct operands\n  Transitive,  // Merge operands and their dependencies\n}\n```\n\n## Edge Cases\n\n### Nested FBT Params\nFBT params can be nested, and all levels must be in the same scope:\n```javascript\n<fbt>\n  Hello <fbt:param name=\"user\">\n    <fbt:param name=\"firstName\">{user.firstName}</fbt:param>\n  </fbt:param>\n</fbt>\n```\n\n### FBT with Complex Expressions\nComplex expressions as operands have their entire dependency chain merged:\n```javascript\n<fbt>\n  Count: <fbt:param name=\"count\">{items.length * multiplier}</fbt:param>\n</fbt>\n// Both items.length and multiplier expressions are merged into fbt scope\n```\n\n### Custom Macros\nUser-defined macros can specify their inlining behavior:\n```typescript\ncustomMacros: [\n  ['myMacro', { inlineLevel: InlineLevel.Transitive }],\n]\n```\n\n### Method Calls on FBT\n`fbt.param()`, `fbt.plural()`, etc. are handled as method calls:\n```javascript\nfbt(\n  fbt.param('count', items.length),  // MethodCall on fbt\n  'description'\n)\n```\n\n### JSX vs Call Syntax\nBoth JSX and call syntax for FBT are handled:\n```javascript\n// JSX syntax\n<fbt desc=\"greeting\">Hello</fbt>\n\n// Call syntax\nfbt('Hello', 'greeting')\n```\n\n## Built-in FBT Tags\nThe pass recognizes these FBT constructs:\n- `fbt` / `fbt.c` - Main translation functions\n- `fbt:param` - Parameter substitution\n- `fbt:plural` - Plural handling\n- `fbt:enum` - Enumeration values\n- `fbt:name` - Name parameters\n- `fbt:pronoun` - Pronoun handling\n- `fbs` - Simple string translation\n\n## TODOs\nNone in the source file.\n\n## Example\n\n### Fixture: `fbt/fbt-call.js`\n\n**Input:**\n```javascript\nfunction Component(props) {\n  const text = fbt(\n    `${fbt.param('count', props.count)} items`,\n    'Number of items'\n  );\n  return <div>{text}</div>;\n}\n```\n\n**Before MemoizeFbtAndMacroOperandsInSameScope:**\n```\n[1] $18 = LoadGlobal import fbt from 'fbt'\n[2] $19 = LoadGlobal import fbt from 'fbt'\n[3] $20_@0[3:8] = PropertyLoad $19.param\n[4] $21 = \"(key) count\"\n[5] $22 = LoadLocal props$17\n[6] $23 = PropertyLoad $22.count\n[7] $24_@0[3:8] = MethodCall $19.$20_@0($21, $23)  // fbt.param call\n[8] $25 = `${$24_@0} items`\n[9] $26 = \"(description) Number of items\"\n[10] $27_@1 = Call $18($25, $26)  // fbt call\n```\n\n**After MemoizeFbtAndMacroOperandsInSameScope:**\n```\n[1] $18_@1[1:11] = LoadGlobal import fbt from 'fbt'  // Merged to @1\n[2] $19 = LoadGlobal import fbt from 'fbt'\n[3] $20_@0[3:8] = PropertyLoad $19.param\n[4] $21 = \"(key) count\"\n[5] $22 = LoadLocal props$17\n[6] $23 = PropertyLoad $22.count\n[7] $24_@1[1:11] = MethodCall $19.$20_@0($21, $23)  // Merged to @1\n[8] $25_@1[1:11] = `${$24_@1} items`                // Merged to @1\n[9] $26_@1[1:11] = \"(description) Number of items\" // Merged to @1\n[10] $27_@1[1:11] = Call $18_@1($25_@1, $26_@1)     // Main fbt scope @1\n```\n\n**Generated Code:**\n```javascript\nfunction Component(props) {\n  const $ = _c(3);\n  let t0;\n  if ($[0] !== props.count) {\n    // All fbt operands computed in same memoization block\n    t0 = fbt(\n      `${fbt.param(\"count\", props.count)} items`,\n      \"Number of items\"\n    );\n    $[0] = props.count;\n    $[1] = t0;\n  } else {\n    t0 = $[1];\n  }\n  const text = t0;\n  let t1;\n  if ($[2] === Symbol.for(\"react.memo_cache_sentinel\")) {\n    t1 = <div>{text}</div>;\n    $[2] = t1;\n  } else {\n    t1 = $[2];\n  }\n  return t1;\n}\n```\n\nKey observations:\n- All FBT-related operations are in the same memoization scope `@1`\n- `fbt.param`, template literal, and `fbt` call are memoized together\n- This ensures the translation system receives consistent operand values\n- The entire translation is recomputed when any operand (`props.count`) changes\n"

Context variables are variables that are captured by closures and require special handling for correct closure semantics.\n\nThe pass prevents mixing context variable operations (`DeclareContext`, `StoreContext`, `LoadContext`) with local variable operations (`DeclareLocal`, `StoreLocal`, `LoadLocal`, `Destructure`) on the same identifier.\n\n## Input Invariants\n- The function has been lowered to HIR\n- All instructions have been categorized by kind\n- Nested function expressions have been lowered\n\n## Validation Rules\n\n### Rule 1: Consistent Variable Kind\nAll references to the same identifier must use consistent load/store operations:\n- Context variables must only use `DeclareContext`, `StoreContext`, `LoadContext`\n- Local variables must only use `DeclareLocal`, `StoreLocal`, `LoadLocal`\n\n**Error (Invariant violation):**\n```\nExpected all references to a variable to be consistently local or context references\nIdentifier [place] is referenced as a [kind] variable, but was previously referenced as a [prev.kind] variable\n```\n\n### Rule 2: No Destructuring of Context Variables\nContext variables cannot be destructured using the `Destructure` instruction.\n\n**Error (Todo):**\n```\nSupport destructuring of context variables\n```\n\n### Rule 3: Unhandled Instruction Variants\nIf an instruction has lvalues that the pass does not handle, it throws a Todo error.\n\n**Error (Todo):**\n```\nValidateContextVariableLValues: unhandled instruction variant\nHandle '[kind]' lvalues\n```\n\n## Algorithm\n\n### Phase 1: Initialize Tracking\n```typescript\nconst identifierKinds: Map<IdentifierId, {place: Place, kind: 'local' | 'context' | 'destructure'}> = new Map();\n```\n\n### Phase 2: Visit All Instructions\nThe pass iterates through all blocks and instructions, categorizing each based on its kind:\n\n```typescript\nfor (const [, block] of fn.body.blocks) {\n  for (const instr of block.instructions) {\n    switch (value.kind) {\n      case 'DeclareContext':\n      case 'StoreContext':\n        visit(identifierKinds, value.lvalue.place, 'context');\n        break;\n      case 'LoadContext':\n        visit(identifierKinds, value.place, 'context');\n        break;\n      case 'StoreLocal':\n      case 'DeclareLocal':\n        visit(identifierKinds, value.lvalue.place, 'local');\n        break;\n      case 'LoadLocal':\n        visit(identifierKinds, value.place, 'local');\n        break;\n      case 'PostfixUpdate':\n      case 'PrefixUpdate':\n        visit(identifierKinds, value.lvalue, 'local');\n        break;\n      case 'Destructure':\n        for (const lvalue of eachPatternOperand(value.lvalue.pattern)) {\n          visit(identifierKinds, lvalue, 'destructure');\n        }\n        break;\n      case 'ObjectMethod':\n      case 'FunctionExpression':\n        // Recursively validate nested functions\n        validateContextVariableLValuesImpl(value.loweredFunc.func, identifierKinds);\n        break;\n    }\n  }\n}\n```\n\n### Phase 3: Check Consistency\nFor each place visited, the `visit` function checks if the identifier was previously seen with a different kind:\n\n```typescript\nfunction visit(identifiers, place, kind) {\n  const prev = identifiers.get(place.identifier.id);\n  if (prev !== undefined) {\n    const wasContext = prev.kind === 'context';\n    const isContext = kind === 'context';\n    if (wasContext !== isContext) {\n      // Check for destructuring of context variable\n      if (prev.kind === 'destructure' || kind === 'destructure') {\n        CompilerError.throwTodo({\n          reason: `Support destructuring of context variables`,\n          ...\n        });\n      }\n      // Invariant violation: inconsistent variable kinds\n      CompilerError.invariant(false, {\n        reason: 'Expected all references to be consistently local or context references',\n        ...\n      });\n    }\n  }\n  identifiers.set(place.identifier.id, {place, kind});\n}\n```\n\n## Edge Cases\n\n### Nested Function Expressions\nThe validation recursively processes nested function expressions and object methods, sharing the same `identifierKinds` map. This ensures that a variable captured by a nested function is consistently treated as a context variable throughout the entire function hierarchy.\n\n### Destructuring Patterns\nEach operand in a destructure pattern is visited individually, marked as 'destructure' kind. If the same identifier was previously used as a context variable, a Todo error is thrown since destructuring of context variables is not yet supported.\n\n### Update Expressions\nBoth `PostfixUpdate` (e.g., `x++`) and `PrefixUpdate` (e.g., `++x`) are treated as local variable operations.\n\n## TODOs\n\n1. **Destructuring of context variables** - Currently not supported:\n   ```typescript\n   CompilerError.throwTodo({\n     reason: `Support destructuring of context variables`,\n     ...\n   });\n   ```\n\n2. **Unhandled instruction variants** - Some instruction types with lvalues may not be handled:\n   ```typescript\n   CompilerError.throwTodo({\n     reason: 'ValidateContextVariableLValues: unhandled instruction variant',\n     description: `Handle '${value.kind}' lvalues`,\n     ...\n   });\n   ```\n\n## Example\n\n### Fixture: `error.todo-for-of-loop-with-context-variable-iterator.js`\n\n**Input:**\n```javascript\nimport {useHook} from 'shared-runtime';\n\nfunction Component(props) {\n  const data = useHook();\n  const items = [];\n  // NOTE: `item` is a context variable because it's reassigned and also referenced\n  // within a closure, the `onClick` handler of each item\n  for (let item of props.data) {\n    item = item ?? {}; // reassignment to force a context variable\n    items.push(\n      <div key={item.id} onClick={() => data.set(item)}>\n        {item.id}\n      </div>\n    );\n  }\n  return <div>{items}</div>;\n}\n```\n\n**Error:**\n```\nTodo: Support non-trivial for..of inits\n\nerror.todo-for-of-loop-with-context-variable-iterator.ts:8:2\n   6 |   // NOTE: `item` is a context variable because it's reassigned and also referenced\n   7 |   // within a closure, the `onClick` handler of each item\n>  8 |   for (let item of props.data) {\n     |   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\n>  9 |     item = item ?? {}; // reassignment to force a context variable\n     | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\n...\n> 15 |   }\n     | ^^^^ Support non-trivial for..of inits\n```\n\nNote: This particular error comes from an earlier pass (lowering), but demonstrates the kind of context variable scenarios that this validation is designed to catch.\n"

The pass checks for several common mistakes that developers make when using `useMemo()`:\n\n1. Callbacks should not accept parameters (useMemo callbacks are called with no arguments)\n2. Callbacks should not be async or generator functions (must return a value synchronously)\n3. Callbacks should not reassign variables declared outside the callback (must be pure)\n4. Callbacks should return a value (useMemo is for computing values, not side effects)\n5. The result of useMemo should be used (not discarded)\n\n## Input Invariants\n- The function has been lowered to HIR\n- `useMemo` is either imported directly or accessed via `React.useMemo`\n- Function expressions have been lowered with their parameters and async/generator flags preserved\n\n## Validation Rules\n\n### Rule 1: No Parameters\nuseMemo callbacks must not accept parameters.\n\n**Error:**\n```\nError: useMemo() callbacks may not accept parameters\n\nuseMemo() callbacks are called by React to cache calculations across re-renders.

value.callee : value.property;\n      if (useMemos.has(callee.identifier.id) && value.args.length > 0) {\n        // Validate the callback\n      }\n      break;\n  }\n}\n```\n\n### Phase 3: Validate Callback\nFor each useMemo call, the pass retrieves the callback function expression and validates:\n\n```typescript\nconst body = functions.get(arg.identifier.id);\n\n// Check for parameters\nif (body.loweredFunc.func.params.length > 0) {\n  errors.push(\"useMemo() callbacks may not accept parameters\");\n}\n\n// Check for async/generator\nif (body.loweredFunc.func.async || body.loweredFunc.func.generator) {\n  errors.push(\"useMemo() callbacks may not be async or generator functions\");\n}\n\n// Check for context variable reassignment\nvalidateNoContextVariableAssignment(body.loweredFunc.func, errors);\n\n// Check for return value (if config enabled)\nif (fn.env.config.validateNoVoidUseMemo) {\n  if (!hasNonVoidReturn(body.loweredFunc.func)) {\n    errors.push(\"useMemo() callbacks must return a value\");\n  }\n}\n```\n\n### Phase 4: Validate No Context Variable Assignment\n```typescript\nfunction validateNoContextVariableAssignment(fn: HIRFunction, errors: CompilerError) {\n  const context = new Set(fn.context.map(place => place.identifier.id));\n  for (const block of fn.body.blocks.values()) {\n    for (const instr of block.instructions) {\n      if (value.kind === 'StoreContext') {\n        if (context.has(value.lvalue.place.identifier.id)) {\n          errors.push(\"Cannot reassign variable\");\n        }\n      }\n    }\n  }\n}\n```\n\n### Phase 5: Check for Unused Results\n```typescript\n// Track which useMemo results are referenced\nfor (const operand of eachInstructionValueOperand(value)) {\n  unusedUseMemos.delete(operand.identifier.id);\n}\n\n// At the end, report any unused useMemos\nfor (const loc of unusedUseMemos.values()) {\n  errors.push(\"useMemo() result is unused\");\n}\n```\n\n### Return Value Helper\n```typescript\nfunction hasNonVoidReturn(func: HIRFunction): boolean {\n  for (const [, block] of func.body.blocks) {\n    if (block.terminal.kind === 'return') {\n      if (block.terminal.returnVariant === 'Explicit' ||\n          block.terminal.returnVariant === 'Implicit') {\n        return true;\n      }\n    }\n  }\n  return false;\n}\n```\n\n## Edge Cases\n\n### React.useMemo vs useMemo\nThe pass handles both import styles:\n```javascript\nimport {useMemo} from 'react';\nuseMemo(() => x, [x]);\n\nimport React from 'react';\nReact.useMemo(() => x, [x]);\n```\n\n### Immediately Used Results\nResults that are used immediately don't trigger the \"unused\" warning:\n```javascript\nconst x = useMemo(() => compute(), [dep]);\nreturn x; // x is used\n```\n\n### Void Return Detection\nThe pass checks for explicit and implicit returns. A function with only `return;` statements (void returns) will trigger the \"must return a value\" error.\n\n### VoidUseMemo Errors as Logged Errors\nThe void useMemo errors (no return value, unused result) are logged via `fn.env.logErrors()` rather than thrown immediately. This allows them to be treated differently (e.g., as warnings) based on configuration.\n\n## TODOs\nNone in the source file.\n\n## Example\n\n### Fixture: `error.invalid-useMemo-callback-args.js`\n\n**Input:**\n```javascript\nfunction component(a, b) {\n  let x = useMemo(c => a, []);\n  return x;\n}\n```\n\n**Error:**\n```\nError: useMemo() callbacks may not accept parameters\n\nuseMemo() callbacks are called by React to cache calculations across re-renders.

    "content": "# validateHooksUsage\n\n## File\n`src/Validation/ValidateHooksUsage.ts`\n\n## Purpose\nThis validation pass ensures that the function honors the [Rules of Hooks](https://react.dev/warnings/invalid-hook-call-warning). Specifically, it validates that:\n\n1. Hooks may only be called unconditionally (not in if statements, loops, etc.)\n2. Hooks cannot be used as first-class values (passed around, stored in variables, etc.)\n3. Hooks must be the same function on every render (no dynamic hooks)\n4. Hooks must be called at the top level, not within nested function expressions\n\n## Input Invariants\n- The function has been lowered to HIR\n- Global bindings have been resolved and typed\n- Nested function expressions have been lowered\n\n## Value Kinds Lattice\n\nThe pass uses abstract interpretation with a lattice of value kinds:\n\n```typescript\nenum Kind {\n  Error,        // Hook already used in an invalid way (stop reporting)\n  KnownHook,    // Definitely a hook (from LoadGlobal with hook type)\n  PotentialHook, // Might be a hook (hook-like name but not from global)\n  Global,       // A global value that is not a hook\n  Local,        // A local variable\n}\n```\n\nThe `joinKinds` function merges kinds, with earlier kinds taking precedence:\n- `Error` > `KnownHook` > `PotentialHook` > `Global` > `Local`\n\n## Validation Rules\n\n### Rule 1: No Conditional Hook Calls\nHooks must always be called in a consistent order.\n\n**Error:**\n```\nError: Hooks must always be called in a consistent order, and may not be called conditionally. See the Rules of Hooks (https://react.dev/warnings/invalid-hook-call-warning)\n```\n\n### Rule 2: No Hooks as First-Class Values\nKnown hooks may not be referenced as normal values (only called).\n\n**Error:**\n```\nError: Hooks may not be referenced as normal values, they must be called. See https://react.dev/reference/rules/react-calls-components-and-hooks#never-pass-around-hooks-as-regular-values\n```\n\n### Rule 3: No Dynamic Hooks\nPotential hooks (hook-like names from local scope) may change between renders.\n\n**Error:**\n```\nError: Hooks must be the same function on every render, but this value may change over time to a different function. See https://react.dev/reference/rules/react-calls-components-and-hooks#dont-dynamically-use-hooks\n```\n\n### Rule 4: No Hooks in Nested Functions\nHooks must be called at the top level of a component or custom hook.\n\n**Error:**\n```\nError: Hooks must be called at the top level in the body of a function component or custom hook, and may not be called within function expressions. See the Rules of Hooks (https://react.dev/warnings/invalid-hook-call-warning)\n\nCannot call [hookKind] within a function expression\n```\n\n## Algorithm\n\n### Phase 1: Compute Unconditional Blocks\n```typescript\nconst unconditionalBlocks = computeUnconditionalBlocks(fn);\n```\nDetermines which blocks are guaranteed to execute on every render (not inside conditionals).\n\n### Phase 2: Initialize Tracking\n```typescript\nconst valueKinds = new Map<IdentifierId, Kind>();\n\n// Initialize parameters\nfor (const param of fn.params) {\n  const place = param.kind === 'Identifier' ? param : param.place;\n  const kind = getKindForPlace(place); // PotentialHook if hook-like name\n  setKind(place, kind);\n}\n```\n\n### Phase 3: Track Value Kinds Through Instructions\n\nFor each instruction, the pass tracks how hook-ness flows through values:\n\n```typescript\ncase 'LoadGlobal':\n  // Globals are the source of KnownHook\n  if (getHookKind(fn.env, instr.lvalue.identifier) != null) {\n    setKind(instr.lvalue, Kind.KnownHook);\n  } else {\n    setKind(instr.lvalue, Kind.Global);\n  }\n  break;\n\ncase 'PropertyLoad':\n  // Hook-like property of Global -> KnownHook\n  // Hook-like property of Local -> PotentialHook\n  // Property of KnownHook -> KnownHook (if hook-like name)\n  const objectKind = getKindForPlace(value.object);\n  const isHookProperty = isHookName(value.property);\n  // Determine kind based on object kind and property name\n  break;\n\ncase 'CallExpression':\n  const calleeKind = getKindForPlace(value.callee);\n  const isHookCallee = calleeKind === Kind.KnownHook || calleeKind === Kind.PotentialHook;\n\n  if (isHookCallee && !unconditionalBlocks.has(block.id)) {\n    recordConditionalHookError(value.callee);\n  } else if (calleeKind === Kind.PotentialHook) {\n    recordDynamicHookUsageError(value.callee);\n  }\n  break;\n```\n\n### Phase 4: Check for Invalid Hook References\n\nWhen a `KnownHook` is used as an operand (not as a callee), it's an error:\n\n```typescript\nfunction visitPlace(place: Place): void {\n  const kind = valueKinds.get(place.identifier.id);\n  if (kind === Kind.KnownHook) {\n    recordInvalidHookUsageError(place);\n  }\n}\n```\n\n### Phase 5: Validate Nested Function Expressions\n\nRecursively check that nested functions don't call hooks:\n\n```typescript\nfunction visitFunctionExpression(errors: CompilerError, fn: HIRFunction) {\n  for (const instr of allInstructions(fn)) {\n    if (isCall(instr)) {\n      const callee = getCallee(instr);\n      const hookKind = getHookKind(fn.env, callee.identifier);\n      if (hookKind != null) {\n        errors.push({\n          reason: 'Hooks must be called at the top level...',\n          description: `Cannot call ${hookKind} within a function expression`,\n        });\n      }\n    }\n    // Recursively check nested functions\n    if (isFunctionExpression(instr)) {\n      visitFunctionExpression(errors, instr.value.loweredFunc.func);\n    }\n  }\n}\n```\n\n### Phi Node Handling\n\nFor phi nodes (control flow join points), the pass joins the kinds of all operands:\n\n```typescript\nfor (const phi of block.phis) {\n  let kind = isHookName(phi.place.identifier.name) ? Kind.PotentialHook : Kind.Local;\n  for (const [, operand] of phi.operands) {\n    const operandKind = valueKinds.get(operand.identifier.id);\n    if (operandKind !== undefined) {\n      kind = joinKinds(kind, operandKind);\n    }\n  }\n  valueKinds.set(phi.place.identifier.id, kind);\n}\n```\n\n## Edge Cases\n\n### Optional Calls\nOptional calls like `useHook?.()` are treated as conditional:\n```javascript\nconst result = useHook?.(); // Error: conditional hook call\n```\n\n### Property Access on Hooks\nHook-like properties of known hooks are also known hooks:\n```javascript\nconst useFoo = useHook.useFoo; // useFoo is KnownHook\nuseFoo(); // Must be called unconditionally\n```\n\n### Destructuring from Global\nDestructuring hook-like names from a global creates known hooks:\n```javascript\nconst {useState} = React; // useState is KnownHook\n```\n\n### Hook-Like Names from Local Variables\nHook-like names from local variables are potential hooks:\n```javascript\nconst obj = createObject();\nconst useFoo = obj.useFoo; // PotentialHook\nuseFoo(); // Error: dynamic hook\n```\n\n### Error Deduplication\nThe pass deduplicates errors by source location, and once an error is recorded for a place, it's marked as `Kind.Error` to prevent further errors for the same place.\n\n## TODOs\n\n1. **Fixpoint iteration for loops** - The pass currently skips phi operands whose value is unknown (which can occur in loops). A follow-up could expand this to fixpoint iteration:\n   ```typescript\n   // NOTE: we currently skip operands whose value is unknown\n   // (which can only occur for functions with loops), we may\n   // cause us to miss invalid code in some cases. We should\n   // expand this to a fixpoint iteration in a follow-up.\n   ```\n\n## Example\n\n### Fixture: `rules-of-hooks/error.invalid-hook-if-consequent.js`\n\n**Input:**\n```javascript\nfunction Component(props) {\n  let x = null;\n  if (props.cond) {\n    x = useHook();\n  }\n  return x;\n}\n```\n\n**Error:**\n```\nError: Hooks must always be called in a consistent order, and may not be called conditionally.

    "content": "# validateLocalsNotReassignedAfterRender\n\n## File\n`src/Validation/ValidateLocalsNotReassignedAfterRender.ts`\n\n## Purpose\nThis validation pass prevents a category of bugs where a closure captures a binding from one render but does not update when the binding is reassigned in a later render.\n\nWhen the React Compiler memoizes a function, that function captures bindings at the time of creation. If the function is reused across renders (because its dependencies haven't changed), any reassignments to captured variables will affect the wrong binding version. This can cause inconsistent behavior that's difficult to debug.\n\nThe pass detects when:\n1. A local variable is reassigned within a function expression\n2. That function expression escapes (e.g., passed to useEffect, used as event handler)\n3. The reassignment would occur after render completes (in effects or async callbacks)\n\n## Input Invariants\n- The function has been lowered to HIR\n- Effects have been inferred for all operands (`operand.effect !== Effect.Unknown`)\n- Function signatures have been analyzed for `noAlias` properties\n\n## Validation Rules\n\n### Rule 1: No Reassignment After Render\nVariables cannot be reassigned in functions that escape to be called after render.\n\n**Error:**\n```\nError: Cannot reassign variable after render completes\n\nReassigning `[variable]` after render has completed can cause inconsistent behavior on subsequent renders. Consider using state instead.\n```\n\n### Rule 2: No Reassignment in Async Functions\nVariables cannot be reassigned within async functions (async functions always execute after render).\n\n**Error:**\n```\nError: Cannot reassign variable in async function\n\nReassigning a variable in an async function can cause inconsistent behavior on subsequent renders. Consider using state instead.\n```\n\n## Algorithm\n\n### Phase 1: Track Context Variables\nContext variables are variables declared in the outer component/hook that are captured by inner functions:\n\n```typescript\nconst contextVariables = new Set<IdentifierId>();\n\n// For DeclareContext in the main function, add to tracking\ncase 'DeclareContext':\n  if (!isFunctionExpression) {\n    contextVariables.add(value.lvalue.place.identifier.id);\n  }\n  break;\n```\n\n### Phase 2: Detect Reassigning Functions\nThe pass tracks which functions contain reassignments to context variables:\n\n```typescript\nconst reassigningFunctions = new Map<IdentifierId, Place>();\n\ncase 'FunctionExpression':\ncase 'ObjectMethod':\n  // Recursively check if the function reassigns context variables\n  let reassignment = getContextReassignment(\n    value.loweredFunc.func,\n    contextVariables,\n    true,  // isFunctionExpression\n    isAsync || value.loweredFunc.func.async\n  );\n\n  // Also check if any captured functions reassign\n  if (reassignment === null) {\n    for (const operand of eachInstructionValueOperand(value)) {\n      const fromOperand = reassigningFunctions.get(operand.identifier.id);\n      if (fromOperand !== undefined) {\n        reassignment = fromOperand;\n        break;\n      }\n    }\n  }\n\n  if (reassignment !== null) {\n    // If async, error immediately\n    if (isAsync || value.loweredFunc.func.async) {\n      throw new CompilerError(\"Cannot reassign variable in async function\");\n    }\n    // Otherwise, track this function as reassigning\n    reassigningFunctions.set(lvalue.identifier.id, reassignment);\n  }\n  break;\n```\n\n### Phase 3: Detect Reassignment in Function Expression\nWithin a function expression, a `StoreContext` to a context variable is a reassignment:\n\n```typescript\ncase 'StoreContext':\n  if (isFunctionExpression) {\n    if (contextVariables.has(value.lvalue.place.identifier.id)) {\n      return value.lvalue.place;  // Found a reassignment\n    }\n  } else {\n    // In main function, just track the context variable\n    contextVariables.add(value.lvalue.place.identifier.id);\n  }\n  break;\n```\n\n### Phase 4: Propagate Reassignment Through Data Flow\nReassigning functions flow through local/context stores:\n\n```typescript\ncase 'StoreLocal':\ncase 'StoreContext':\n  const reassignment = reassigningFunctions.get(value.value.identifier.id);\n  if (reassignment !== undefined) {\n    reassigningFunctions.set(value.lvalue.place.identifier.id, reassignment);\n    reassigningFunctions.set(lvalue.identifier.id, reassignment);\n  }\n  break;\n\ncase 'LoadLocal':\n  const reassignment = reassigningFunctions.get(value.place.identifier.id);\n  if (reassignment !== undefined) {\n    reassigningFunctions.set(lvalue.identifier.id, reassignment);\n  }\n  break;\n```\n\n### Phase 5: Check Escape Points\nWhen a reassigning function is used as an operand with `Effect.Freeze`, it means the function escapes (e.g., passed to a hook, used as a prop):\n\n```typescript\nfor (const operand of operands) {\n  const reassignment = reassigningFunctions.get(operand.identifier.id);\n  if (reassignment !== undefined) {\n    if (operand.effect === Effect.Freeze) {\n      // Function escapes - this is an error\n      return reassignment;\n    } else {\n      // Function doesn't escape yet, propagate to lvalues\n      for (const lval of eachInstructionLValue(instr)) {\n        reassigningFunctions.set(lval.identifier.id, reassignment);\n      }\n    }\n  }\n}\n```\n\n### Phase 6: Check Terminal Operands\nReassigning functions used in terminal operands (like return) also escape:\n\n```typescript\nfor (const operand of eachTerminalOperand(block.terminal)) {\n  const reassignment = reassigningFunctions.get(operand.identifier.id);\n  if (reassignment !== undefined) {\n    return reassignment;\n  }\n}\n```\n\n### NoAlias Optimization\nFor function calls with `noAlias` signatures, only the callee needs to be checked (not all arguments):\n\n```typescript\nif (value.kind === 'CallExpression') {\n  const signature = getFunctionCallSignature(fn.env, value.callee.identifier.type);\n  if (signature?.noAlias) {\n    operands = [value.callee];  // Only check the callee\n  }\n}\n```\n\n## Edge Cases\n\n### Nested Async Functions\nAsync functions are always detected as problematic, regardless of nesting level:\n```javascript\nfunction Component() {\n  let x = 0;\n  const f = async () => {\n    const g = () => {\n      x = 1;  // Error: in async context\n    };\n  };\n}\n```\n\n### Function Composition\nIf a reassigning function is captured by another function, that outer function is also marked as reassigning:\n```javascript\nfunction Component() {\n  let x = 0;\n  const reassign = () => { x = 1; };\n  const wrapper = () => { reassign(); };\n  useEffect(wrapper);  // Error: wrapper contains reassign\n}\n```\n\n### NoAlias Functions\nFunctions with `noAlias` signatures don't let their arguments escape, so passing a reassigning function to them is safe:\n```javascript\nfunction Component() {\n  let x = 0;\n  const f = () => { x = 1; };\n  console.log(f);  // OK: console.log has noAlias, f doesn't escape\n}\n```\n\n### Direct Effect Usage\nThe most common case is passing a reassigning function to useEffect:\n```javascript\nfunction Component() {\n  let local;\n  const reassign = () => { local = 'new value'; };\n  useEffect(() => { reassign(); }, []);  // Error\n}\n```\n\n## TODOs\nNone in the source file.\n\n## Example\n\n### Fixture: `error.invalid-reassign-local-variable-in-effect.js`\n\n**Input:**\n```javascript\nimport {useEffect} from 'react';\n\nfunction Component() {\n  let local;\n\n  const reassignLocal = newValue => {\n    local = newValue;\n  };\n\n  const onMount = newValue => {\n    reassignLocal('hello');\n\n    if (local === newValue) {\n      // Without React Compiler, `reassignLocal` is freshly created\n      // on each render, capturing a binding to the latest `local`,\n      // such that invoking reassignLocal will reassign the same\n      // binding that we are observing in the if condition, and\n      // we reach this branch\n      console.log('`local` was updated!');\n    } else {\n      // With React Compiler enabled, `reassignLocal` is only created\n      // once, capturing a binding to `local` in that render pass.\n      // Therefore, calling `reassignLocal` will reassign the wrong\n      // version of `local`, and not update the binding we are checking\n      // in the if condition.\n      throw new Error('`local` not updated!');\n    }\n  };\n\n  useEffect(() => {\n    onMount();\n  }, [onMount]);\n\n  return 'ok';\n}\n```\n\n**Error:**\n```\nError: Cannot reassign variable after render completes\n\nReassigning `local` after render has completed can cause inconsistent behavior on subsequent renders.

Initialize a set `unconditionalSetStateFunctions` to track functions that unconditionally call setState\n3. Traverse all blocks and instructions:\n   - **LoadLocal/StoreLocal**: Propagate setState tracking through variable assignments and loads\n   - **FunctionExpression/ObjectMethod**: Recursively check if the function unconditionally calls setState. If so, add the function's lvalue to the tracking set\n   - **StartMemoize/FinishMemoize**: Track when inside a manual memoization block (useMemo/useCallback)\n   - **CallExpression**: Check if the callee is a setState function or tracked setter:\n     - If inside a memoize block, emit a useMemo-specific error\n     - If in an unconditional block, emit a render-time setState error\n\n### Key Helper: `computeUnconditionalBlocks`\nUses post-dominator tree analysis to find blocks that always execute when the function runs.

Error boundaries should be used instead.\n\nSee: https://react.dev/reference/react/Component#catching-rendering-errors-with-an-error-boundary\n\n## Input Invariants\n- Operates on HIRFunction (pre-reactive scope inference)\n- Blocks are traversed in order\n- Only runs when `outputMode === 'lint'`\n\n## Validation Rules\nThe pass errors when `JsxExpression` or `JsxFragment` instructions are found within a try block.\n\n**Error message:**\n```\nError: Avoid constructing JSX within try/catch\n\nReact does not immediately render components when JSX is rendered, so any errors from this component will not be caught by the try/catch. To catch errors in rendering a given component, wrap that component in an error boundary.\n```\n\n### Important distinction\n- JSX in a **try block**: Error\n- JSX in a **catch block** (not nested in outer try): Allowed\n- JSX in a **catch block** (nested in outer try): Error\n\n## Algorithm\n1. Maintain a stack `activeTryBlocks` of currently active try statement handler block IDs\n2. For each block:\n   - Remove the current block from `activeTryBlocks` if it matches a handler (we've exited the try scope)\n   - If `activeTryBlocks` is not empty (we're inside a try block):\n     - Check each instruction for `JsxExpression` or `JsxFragment`\n     - If found, push an error\n   - If the block's terminal is a `try` terminal, push its handler block ID to `activeTryBlocks`\n\n### Block tracking with `retainWhere`\nThe `retainWhere` utility is used to remove the current block from `activeTryBlocks` at the start of each block. When we reach a catch handler block, it gets removed from the active list, allowing JSX in catch blocks (unless there's an outer try).\n\n## Edge Cases\n\n### Allowed: JSX in catch (no outer try)\n```javascript\n// Valid - catch block is not inside a try\nfunction Component() {\n  try {\n    doSomething();\n  } catch {\n    return <ErrorMessage />; // OK\n  }\n}\n```\n\n### Error: JSX in catch with outer try\n```javascript\n// Error - catch is inside outer try\nfunction Component() {\n  try {\n    try {\n      doSomething();\n    } catch {\n      return <ErrorMessage />; // Error!\n    }\n  } catch {\n    return null;\n  }\n}\n```\n\n### Error: JSX assigned in try\n```javascript\n// Error - JSX creation is in try block\nfunction Component() {\n  let el;\n  try {\n    el = <div />; // Error here\n  } catch {\n    return null;\n  }\n  return el;\n}\n```\n\n### Finally blocks\nThe validation currently has TODOs for handling try/catch/finally properly. Files like `error.todo-invalid-jsx-in-try-with-finally.js` indicate these are known unsupported cases.\n\n## TODOs\nBased on fixture naming patterns:\n- `error.todo-invalid-jsx-in-try-with-finally.js` - Try blocks with finally clauses\n- `error.todo-invalid-jsx-in-catch-in-outer-try-with-finally.js` - Nested try/catch in try with finally\n\n## Example\n\n### Fixture: `invalid-jsx-in-try-with-catch.js`\n\n**Input:**\n```javascript\n// @loggerTestOnly @validateNoJSXInTryStatements @outputMode:\"lint\"\nfunction Component(props) {\n  let el;\n  try {\n    el = <div />;\n  } catch {\n    return null;\n  }\n  return el;\n}\n```\n\n**Error:**\n```\nError: Avoid constructing JSX within try/catch\n\nReact does not immediately render components when JSX is rendered, so any errors from this component will not be caught by the try/catch. To catch errors in rendering a given component, wrap that component in an error boundary.\n\ninvalid-jsx-in-try-with-catch.ts:5:9\n  3 |   let el;\n  4 |   try {\n> 5 |     el = <div />;\n    |          ^^^^^^^ Avoid constructing JSX within try/catch\n  6 |   } catch {\n  7 |     return null;\n  8 |   }\n```\n\n**Why it fails:** The `<div />` JSX element is created inside a try block. If the developer expects this to catch errors from rendering the div, they will be surprised - the try/catch will only catch errors from creating the JSX object (which is rare), not from React actually rendering it later. The correct approach is to use an error boundary component to catch rendering errors.\n\n### Fixture: `invalid-jsx-in-catch-in-outer-try-with-catch.js`\n\n**Input:**\n```javascript\n// @loggerTestOnly @validateNoJSXInTryStatements @outputMode:\"lint\"\nimport {identity} from 'shared-runtime';\n\nfunction Component(props) {\n  let el;\n  try {\n    let value;\n    try {\n      value = identity(props.foo);\n    } catch {\n      el = <div value={value} />;\n    }\n  } catch {\n    return null;\n  }\n  return el;\n}\n```\n\n**Error:**\n```\nError: Avoid constructing JSX within try/catch\n\n...\n\ninvalid-jsx-in-catch-in-outer-try-with-catch.ts:11:11\n   9 |       value = identity(props.foo);\n  10 |     } catch {\n> 11 |       el = <div value={value} />;\n     |            ^^^^^^^^^^^^^^^^^^^^^ Avoid constructing JSX within try/catch\n```\n\n**Why it fails:** Even though the JSX is in a catch block, that catch block is itself inside an outer try block. The outer try's catch won't catch rendering errors from the JSX any more than the inner try would.\n"

    "content": "# validateNoImpureValuesInRender\n\n## File\n`src/Validation/ValidateNoImpureValuesInRender.ts`\n\n## Purpose\nThis validation pass ensures that impure values (values derived from non-deterministic function calls) are not used in render output. Impure values can produce unstable results that update unpredictably when the component re-renders, violating React's requirement that components be pure and idempotent.\n\nThe pass tracks values produced by impure functions (like `Date.now()`, `Math.random()`, `performance.now()`) and errors if those values flow into JSX props, component return values, or other render-time contexts.\n\n## Input Invariants\n- The function has been through effect inference\n- Aliasing effects have been computed on instructions\n- `Impure` effects mark values from non-deterministic sources\n- `Render` effects mark values used in render context\n\n## Validation Rules\nThe pass produces errors when:\n\n1. **Impure value in render context**: A value marked with an `Impure` effect flows into a position marked with a `Render` effect\n2. **Impure function returns in render**: A function that returns an impure value is called during render\n\nError messages produced:\n- Category: `ImpureValues`\n- Reason: \"Cannot access impure value during render\"\n- Description: \"Calling an impure function can produce unstable results that update unpredictably when the component happens to re-render.\"\n\nThe error points to two locations:\n1. Where the impure value is used in render (e.g., as a JSX prop)\n2. Where the impure value originates (e.g., the `Date.now()` call)\n\n## Algorithm\n\n### Phase 1: Infer Impure Values\nThe pass iterates over all instructions to build a map of which identifiers contain impure values:\n\n```typescript\nfunction inferImpureValues(\n  fn: HIRFunction,\n  impure: Map<IdentifierId, ImpureEffect>,\n  impureFunctions: Map<IdentifierId, ImpuritySignature>,\n  cache: FunctionCache,\n): ImpuritySignature\n```\n\nThe algorithm uses a fixed-point iteration that propagates impurity through data flow:\n\n1. **Process phi nodes**: If any operand of a phi is impure, the phi result is impure\n2. **Process effects**: For each instruction's effects:\n   - `Impure` effect: Mark the destination identifier as impure\n   - `Alias/Assign/Capture/CreateFrom/ImmutableCapture`: Propagate impurity from source to destination\n   - `CreateFunction`: Recursively analyze function expressions\n   - `Apply`: When calling a function with an impurity signature, propagate impurity to call results\n\n3. **Control flow sensitivity**: The pass also considers control-flow dominators to detect impure values that flow through conditional branches\n\n### Phase 2: Validate Render Effects\nAfter impurity inference converges, the pass validates all `Render` effects:\n\n```typescript\nfunction validateRenderEffect(effect: RenderEffect): void {\n  const impureEffect = impure.get(effect.place.identifier.id);\n  if (impureEffect != null) {\n    // Emit error\n  }\n}\n```\n\n### Special Cases\n- Values stored in refs (`isUseRefType`) are allowed to be impure since refs are not rendered\n- JSX elements are excluded from impurity propagation (`isJsxType`)\n\n## Edge Cases\n\n### Impure Values Through Helper Functions\nIf a helper function returns an impure value and is called during render, both the call site and the original impure source are reported:\n\n```javascript\nfunction Component() {\n  const now = () => Date.now();  // Source of impurity\n  const render = () => {\n    return <div>{now()}</div>;   // Error: impure value in render\n  };\n  return <div>{render()}</div>;  // Error: impure value in render\n}\n```\n\n### Indirect Impurity Through Mutation\nWhen an impure value is captured into another value through mutation, the destination becomes impure:\n\n```javascript\nfunction Component() {\n  const obj = {};\n  obj.time = Date.now();  // obj becomes impure\n  return <Foo obj={obj} />;  // Error\n}\n```\n\n### Phi Node Propagation\nImpurity propagates through control flow merges:\n\n```javascript\nfunction Component({cond}) {\n  let x;\n  if (cond) {\n    x = Date.now();  // Impure path\n  } else {\n    x = 0;           // Pure path\n  }\n  return <Foo x={x} />;  // Error: x may be impure\n}\n```\n\n## TODOs\nFrom the source file:\n\n```typescript\n/**\n * TODO: consider propagating impurity for assignments/mutations that\n * are controlled by an impure value.\n *\n * Example: This should error since we know the semantics of array.push,\n * it's a definite Mutate and definite Capture, not maybemutate+maybecapture:\n *\n * let x = [];\n * if (Date.now() < START_DATE) {\n *   x.push(1);\n * }\n * return <Foo x={x} />\n */\n```\n\n## Example\n\n### Fixture: `error.invalid-impure-functions-in-render.js`\n\n**Input:**\n```javascript\n// @validateNoImpureFunctionsInRender\n\nfunction Component() {\n  const date = Date.now();\n  const now = performance.now();\n  const rand = Math.random();\n  return <Foo date={date} now={now} rand={rand} />;\n}\n```\n\n**Error:**\n```\nFound 3 errors:\n\nError: Cannot access impure value during render\n\nCalling an impure function can produce unstable results that update unpredictably\nwhen the component happens to re-render.\n(https://react.dev/reference/rules/components-and-hooks-must-be-pure#components-and-hooks-must-be-idempotent).\n\nerror.invalid-impure-functions-in-render.ts:7:20\n  5 |   const now = performance.now();\n  6 |   const rand = Math.random();\n> 7 |   return <Foo date={date} now={now} rand={rand} />;\n    |                     ^^^^ Cannot access impure value during render\n  8 | }\n\nerror.invalid-impure-functions-in-render.ts:4:15\n  2 |\n  3 | function Component() {\n> 4 |   const date = Date.now();\n    |                ^^^^^^^^^^ `Date.now` is an impure function.\n  5 |   const now = performance.now();\n\nError: Cannot access impure value during render\n...\n```\n\nKey observations:\n- Each impure function call (`Date.now`, `performance.now`, `Math.random`) produces a separate error\n- The error shows both the usage location (in JSX) and the source location (the impure call)\n- The pass is enabled via the `@validateNoImpureFunctionsInRender` pragma\n"

However, if a function already has a known mutation effect, conditional mutations will propagate that effect:\n\n```javascript\nfunction Component(cond) {\n  const cache = new Map();\n  const fn = () => {\n    cache.set('a', 1);  // Definite mutation\n  };\n  const fn2 = fn;  // fn2 inherits mutation effect\n  return <Foo fn={fn2} />;  // Error\n}\n```\n\n### Nested Function Expressions\nMutation effects propagate through assignments:\n\n```javascript\nfunction Component() {\n  const cache = new Map();\n  const inner = () => cache.set('key', 'value');\n  const outer = inner;  // outer inherits mutation effect\n  return <Foo fn={outer} />;  // Error\n}\n```\n\n## TODOs\nNone in the source file.\n\n## Example\n\n### Fixture: `error.invalid-pass-mutable-function-as-prop.js`\n\n**Input:**\n```javascript\n// @validateNoFreezingKnownMutableFunctions\nfunction Component() {\n  const cache = new Map();\n  const fn = () => {\n    cache.set('key', 'value');\n  };\n  return <Foo fn={fn} />;\n}\n```\n\n**Error:**\n```\nFound 1 error:\n\nError: Cannot modify local variables after render completes\n\nThis argument is a function which may reassign or mutate `cache` after render, which can cause inconsistent behavior on subsequent renders.

    "content": "# validateExhaustiveDependencies\n\n## File\n`src/Validation/ValidateExhaustiveDependencies.ts`\n\n## Purpose\nThis validation pass ensures that manual memoization (useMemo, useCallback) and effect hooks (useEffect, useLayoutEffect) have correct dependency arrays. The pass compares developer-specified dependencies against the actual values referenced within the memoized function or effect callback to detect:\n\n1. **Missing dependencies**: Values used in the function that are not listed in the dependency array, causing the memoized value or effect to update less frequently than expected\n2. **Extra dependencies**: Values listed in the dependency array that are not actually used, causing unnecessary re-computation or effect re-runs\n3. **Overly precise dependencies**: Dependencies that access deeper property paths than what is actually used (e.g., `x.y.z` when only `x.y` is accessed)\n\nThe goal is to ensure that auto-memoization by the compiler will not substantially change program behavior.\n\n## Input Invariants\n- The function has been through `StartMemoize` and `FinishMemoize` instruction insertion\n- Manual dependency arrays have been parsed and associated with memoization blocks\n- Reactive identifiers have been computed\n- Optional chaining paths have been analyzed\n\n## Validation Rules\nThe pass produces errors for:\n\n1. **Missing dependency in useMemo/useCallback**: A reactive value is used but not listed in deps\n2. **Extra dependency in useMemo/useCallback**: A value is listed but not used\n3. **Missing dependency in useEffect**: A value used in the effect callback is not in the deps array\n4. **Extra dependency in useEffect**: A value in deps is not used in the callback\n5. **Overly precise dependency**: The manual dep accesses a deeper path than what's actually used\n6. **Global as dependency**: Module-level values should not be listed as dependencies\n7. **useEffectEvent in dependency array**: Functions from useEffectEvent must not be in deps\n\n**Exception - Optional dependencies**: Non-reactive values of stable types (refs, setState) or primitive types are optional and don't need to be listed.\n\nError messages produced:\n- Categories: `MemoDependencies` or `EffectExhaustiveDependencies`\n- Reasons:\n  - \"Found missing memoization dependencies\"\n  - \"Found extra memoization dependencies\"\n  - \"Found missing/extra memoization dependencies\"\n  - \"Found missing effect dependencies\"\n  - \"Found extra effect dependencies\"\n  - \"Found missing/extra effect dependencies\"\n- Messages:\n  - \"Missing dependency `{dep}`\"\n  - \"Unnecessary dependency `{dep}`\"\n  - \"Overly precise dependency `{manual}`, use `{inferred}` instead\"\n  - \"Functions returned from `useEffectEvent` must not be included in the dependency array\"\n  - \"Values declared outside of a component/hook should not be listed as dependencies\"\n\n## Algorithm\n\n### Phase 1: Collect Reactive Identifiers\nScan all instructions to identify which identifiers are reactive:\n\n```typescript\nfunction collectReactiveIdentifiersHIR(fn: HIRFunction): Set<IdentifierId> {\n  const reactive = new Set<IdentifierId>();\n  for (const block of fn.body.blocks.values()) {\n    for (const instr of block.instructions) {\n      for (const lvalue of eachInstructionLValue(instr)) {\n        if (lvalue.reactive) {\n          reactive.add(lvalue.identifier.id);\n        }\n      }\n      // ... also check operands\n    }\n  }\n  return reactive;\n}\n```\n\n### Phase 2: Find Optional Places\nIdentify places that are within optional chaining expressions:\n\n```typescript\nfunction findOptionalPlaces(fn: HIRFunction): Map<IdentifierId, boolean> {\n  // Walks through optional terminals to track which identifiers\n  // are accessed via optional chaining (?.property)\n}\n```\n\n### Phase 3: Collect Dependencies\nThe core algorithm processes each block, tracking:\n- `temporaries`: Map of identifier IDs to their dependency information\n- `locals`: Set of identifiers declared within the current scope\n- `dependencies`: Set of inferred dependencies\n\n```typescript\nfunction collectDependencies(\n  fn: HIRFunction,\n  temporaries: Map<IdentifierId, Temporary>,\n  callbacks: {\n    onStartMemoize: (...) => void;\n    onFinishMemoize: (...) => void;\n    onEffect: (...) => void;\n  },\n  isFunctionExpression: boolean,\n): Temporary {\n  for (const block of fn.body.blocks.values()) {\n    // Process phi nodes - merge dependencies from control flow\n    for (const phi of block.phis) {\n      // Aggregate dependencies from all operands\n    }\n\n    for (const instr of block.instructions) {\n      switch (value.kind) {\n        case 'LoadLocal':\n        case 'LoadContext':\n          // Track dependency path through the temporary\n          break;\n        case 'PropertyLoad':\n          // Extend dependency path: x -> x.y\n          break;\n        case 'FunctionExpression':\n          // Recursively collect dependencies from nested function\n          break;\n        case 'StartMemoize':\n          // Begin tracking dependencies for this memo block\n          break;\n        case 'FinishMemoize':\n          // Validate collected dependencies against manual deps\n          break;\n        case 'CallExpression':\n        case 'MethodCall':\n          // Check for effect hooks and validate their deps\n          break;\n      }\n    }\n  }\n}\n```\n\n### Phase 4: Validate Dependencies\nCompare inferred dependencies against manual dependencies:\n\n```typescript\nfunction validateDependencies(\n  inferred: Array<InferredDependency>,\n  manualDependencies: Array<ManualMemoDependency>,\n  reactive: Set<IdentifierId>,\n  ...\n): CompilerDiagnostic | null {\n  // Sort and deduplicate inferred dependencies\n  // For each inferred dep, check if there's a matching manual dep\n  // For each manual dep, check if it corresponds to an inferred dep\n  // Report missing and extra dependencies\n}\n```\n\n### Dependency Matching Rules\n- If `x.y.z` is inferred, `x`, `x.y`, or `x.y.z` are valid manual deps\n- Optional chaining is handled: `x?.y` inferred can match `x.y` manual (ignoring optionals)\n- Stable types (refs, setState) that are non-reactive are optional\n- Global values should not be in dependency arrays\n- useEffectEvent return values should not be in dependency arrays\n\n## Edge Cases\n\n### Overly Precise Dependency (Error)\n```javascript\nconst a = useMemo(() => {\n  return x?.y.z?.a;\n}, [x?.y.z?.a.b]);  // Error: should be [x?.y.z?.a]\n```\n\n### Unnecessary Dependencies (Error)\n```javascript\nconst f = useMemo(() => {\n  return [];\n}, [x, y.z, GLOBAL]);  // Error: all deps are unnecessary\n```\n\n### Reactive Stable Type (Error)\n```javascript\nconst ref1 = useRef(null);\nconst ref2 = useRef(null);\nconst ref = z ? ref1 : ref2;  // ref is reactive (depends on z)\nconst cb = useMemo(() => {\n  return () => ref.current;\n}, []);  // Error: missing dep 'ref' (reactive even though stable type)\n```\n\n### useEffectEvent in Dependencies (Error)\n```javascript\nconst effectEvent = useEffectEvent(() => log(x));\nuseEffect(() => {\n  effectEvent();\n}, [effectEvent]);  // Error: useEffectEvent returns should not be in deps\n```\n\n### Effect with Missing and Extra Dependencies (Error)\n```javascript\nuseEffect(() => {\n  log(x, z);\n}, [x, y]);  // Error: missing z, extra y\n```\n\n### Valid Dependency Specifications\n```javascript\n// All valid - deps cover or exceed what's used\nconst b = useMemo(() => x.y.z?.a, [x.y.z.a]);  // OK\nconst d = useMemo(() => x?.y?.[(console.log(y), z?.b)], [x?.y, y, z?.b]);  // OK\nconst e = useMemo(() => { e.push(x); return e; }, [x]);  // OK\n```\n\n## Configuration\nThe validation can be configured via compiler options:\n\n```typescript\n// For useMemo/useCallback\nvalidateExhaustiveMemoizationDependencies: boolean\n\n// For useEffect and similar\nvalidateExhaustiveEffectDependencies: 'off' | 'all' | 'missing-only' | 'extra-only'\n```\n\nThe `missing-only` and `extra-only` modes allow validating only one category of errors.\n\n## TODOs\nFrom the source file:\n\n```typescript\n/**\n * TODO: Invalid, Complex Deps\n *\n * Handle cases where the user deps were not simple identifiers + property chains.\n * We try to detect this in ValidateUseMemo but we miss some cases.

    "content": "# validatePreservedManualMemoization\n\n## File\n`src/Validation/ValidatePreservedManualMemoization.ts`\n\n## Purpose\nValidates that all explicit manual memoization (`useMemo`/`useCallback`) from the original source code is accurately preserved in the compiled output. This ensures that values the developer intended to be memoized remain memoized after compilation.\n\n## Input Invariants\n- Operates on ReactiveFunction (post-reactive scope inference)\n- Manual memoization markers (`StartMemoize`/`FinishMemoize`) are present from earlier passes\n- Scopes have been assigned and merged as appropriate\n\n## Validation Rules\nThis pass validates three conditions:\n\n### 1. Dependencies not mutated later\nValidates that dependencies of manual memoization are not mutated after the memoization call:\n```\nExisting memoization could not be preserved. This dependency may be modified later\n```\n\n### 2. Inferred dependencies match source\nValidates that the compiler's inferred dependencies match the manually specified dependencies:\n```\nExisting memoization could not be preserved. The inferred dependencies did not match\nthe manually specified dependencies, which could cause the value to change more or\nless frequently than expected. The inferred dependency was `X`, but the source\ndependencies were [Y, Z].\n```\n\n### 3. Output value is memoized\nValidates that the memoized value actually ends up in a reactive scope:\n```\nExisting memoization could not be preserved. This value was memoized in source but\nnot in compilation output\n```\n\n## Algorithm\n\n### State Management\nThe visitor tracks:\n- `scopes: Set<ScopeId>` - All completed reactive scopes\n- `prunedScopes: Set<ScopeId>` - Scopes that were pruned\n- `temporaries: Map<IdentifierId, ManualMemoDependency>` - Temporary variable mappings\n- `manualMemoState: ManualMemoBlockState | null` - Current manual memoization context\n\n### ManualMemoBlockState\n```typescript\ntype ManualMemoBlockState = {\n  reassignments: Map<DeclarationId, Set<Identifier>>;  // Track inlined useMemo reassignments\n  loc: SourceLocation;                                   // Source location for errors\n  decls: Set<DeclarationId>;                             // Declarations within the memo block\n  depsFromSource: Array<ManualMemoDependency> | null;   // Original deps from source\n  manualMemoId: number;                                  // Unique ID for this memoization\n};\n```\n\n### Processing Flow\n\n1. **On `StartMemoize` instruction:**\n   - Validate that dependencies' scopes have completed (not mutated later)\n   - Initialize `manualMemoState` with source dependencies\n   - Push error if any dependency's scope hasn't completed yet\n\n2. **During memo block (between Start/Finish):**\n   - Track all declarations made within the block\n   - Track reassignments for inlined useMemo handling\n   - Record property loads and temporaries\n\n3. **On scope completion:**\n   - Validate each scope dependency against source dependencies using `compareDeps()`\n   - An inferred dependency matches if:\n     - Root identifiers are the same (same named variable)\n     - Paths are identical, OR\n     - Inferred path is more specific (not involving `.current` refs)\n\n4. **On `FinishMemoize` instruction:**\n   - Validate that the memoized value is in a completed scope\n   - Handle inlined useMemo with reassignment tracking\n   - Push error if value is unmemoized\n\n### Dependency Comparison Results\n```typescript\nenum CompareDependencyResult {\n  Ok = 0,                    // Dependencies match\n  RootDifference = 1,        // Different root variables\n  PathDifference = 2,        // Different property paths\n  Subpath = 3,               // Inferred is less specific\n  RefAccessDifference = 4,   // ref.current access differs\n}\n```\n\n## Edge Cases\n\n### Inlined useMemo Handling\nWhen useMemo is inlined, it produces `let` declarations followed by reassignments. The pass tracks these reassignments to ensure all code paths produce memoized values.\n\n### Ref Access\nSpecial handling for `.current` property access on refs. Since `ref_prev === ref_new` does not imply `ref_prev.current === ref_new.current`, the pass is strict about ref access differences.\n\n### More Specific Dependencies\nIf the compiler infers a more specific dependency (e.g., `obj.prop.value` instead of `obj`), this is acceptable as long as it doesn't involve ref access.\n\n## TODOs\nNone found in the source.\n\n## Example\n\n### Fixture: `error.preserve-use-memo-ref-missing-reactive.ts`\n\n**Input:**\n```javascript\n// @validatePreserveExistingMemoizationGuarantees\nimport {useCallback, useRef} from 'react';\n\nfunction useFoo({cond}) {\n  const ref1 = useRef<undefined | (() => undefined)>();\n  const ref2 = useRef<undefined | (() => undefined)>();\n  const ref = cond ? ref1 : ref2;\n\n  return useCallback(() => {\n    if (ref != null) {\n      ref.current();\n    }\n  }, []);\n}\n```\n\n**Error:**\n```\nFound 1 error:\n\nCompilation Skipped: Existing memoization could not be preserved\n\nReact Compiler has skipped optimizing this component because the existing manual\nmemoization could not be preserved. The inferred dependencies did not match the\nmanually specified dependencies, which could cause the value to change more or\nless frequently than expected. The inferred dependency was `ref`, but the source\ndependencies were []. Inferred dependency not present in source.\n\nerror.preserve-use-memo-ref-missing-reactive.ts:9:21\n>  9 |   return useCallback(() => {\n     |                      ^^^^^^^\n> 10 |     if (ref != null) {\n> 11 |       ref.current();\n> 12 |     }\n> 13 |   }, []);\n     | ^^^^ Could not preserve existing manual memoization\n```\n\n**Why it fails:** The callback uses `ref` which is conditionally assigned based on `cond`. The compiler infers `ref` as a dependency, but the source specifies an empty dependency array `[]`. This mismatch means the memoization cannot be preserved as-is.\n"

    "content": "# validateStaticComponents\n\n## File\n`src/Validation/ValidateStaticComponents.ts`\n\n## Purpose\nValidates that components used in JSX are not created dynamically during render. Components created during render will have their state reset on every re-render because React sees them as new component types each time. This is a common React anti-pattern that causes bugs and poor performance.\n\n## Input Invariants\n- Operates on HIRFunction (pre-reactive transformation)\n- All instructions and phi nodes are present\n- JSX expressions have been lowered to `JsxExpression` instruction values\n\n## Validation Rules\nWhen a JSX element uses a component that was dynamically created during render, the pass produces:\n```\nCannot create components during render. Components created during render will reset\ntheir state each time they are created. Declare components outside of render\n```\n\nThe error includes two locations:\n1. Where the component is used in JSX\n2. Where the component was originally created\n\n### What constitutes \"dynamically created\"?\nThe following instruction kinds mark a value as dynamically created:\n- `FunctionExpression` - An inline function definition\n- `NewExpression` - A `new` constructor call\n- `MethodCall` - A method call that returns a value\n- `CallExpression` - A function call that returns a value\n\n## Algorithm\n\n1. Create a `Map<IdentifierId, SourceLocation>` called `knownDynamicComponents` to track identifiers whose values are dynamically created\n\n2. Iterate through all blocks in evaluation order\n\n3. For each block, first process phi nodes:\n   - If any phi operand is in `knownDynamicComponents`, add the phi result to the map\n   - This propagates dynamic-ness through control flow joins\n\n4. For each instruction in the block:\n   - **FunctionExpression, NewExpression, MethodCall, CallExpression**: Add the lvalue to `knownDynamicComponents` with its source location\n   - **LoadLocal**: If the loaded value is dynamic, mark the lvalue as dynamic\n   - **StoreLocal**: If the stored value is dynamic, mark both the lvalue and the store target as dynamic\n   - **JsxExpression**: If the JSX tag is an identifier that is in `knownDynamicComponents`, push a diagnostic error\n\n5. Return the collected errors\n\n### Data Flow Tracking\nThe pass tracks how dynamic values flow through the program:\n- Through variable assignments (`StoreLocal`, `LoadLocal`)\n- Through phi nodes (conditional assignments)\n- Into JSX component positions\n\n## Edge Cases\n\n### Conditionally Assigned Components\n```javascript\nfunction Example({cond}) {\n  let Component;\n  if (cond) {\n    Component = createComponent();  // Dynamic!\n  } else {\n    Component = OtherComponent;     // Static\n  }\n  return <Component />;  // Error: Component may be dynamic\n}\n```\nThe phi node joins the conditional paths, and since one path is dynamic, the result is considered dynamic.\n\n### Component Returned from Hooks/Functions\n```javascript\nfunction Example() {\n  const Component = useCreateComponent();  // CallExpression - dynamic\n  return <Component />;  // Error\n}\n```\n\n### Factory Functions\n```javascript\nfunction Example() {\n  const Component = createComponent();  // CallExpression - dynamic\n  return <Component />;  // Error\n}\n```\n\n### Safe Patterns (No Error)\n```javascript\n// Component defined outside render\nconst MyComponent = () => <div />;\n\nfunction Example() {\n  return <MyComponent />;  // OK - not created during render\n}\n```\n\n## TODOs\nNone found in the source.\n\n## Example\n\n### Fixture: `static-components/invalid-dynamically-construct-component-in-render.js`\n\n**Input:**\n```javascript\n// @validateStaticComponents\nfunction Example(props) {\n  const Component = createComponent();\n  return <Component />;\n}\n```\n\n**Error (from logs):**\n```json\n{\n  \"kind\": \"CompileError\",\n  \"detail\": {\n    \"options\": {\n      \"category\": \"StaticComponents\",\n      \"reason\": \"Cannot create components during render\",\n      \"description\": \"Components created during render will reset their state each time they are created. Declare components outside of render\",\n      \"details\": [\n        {\n          \"kind\": \"error\",\n          \"loc\": { \"start\": { \"line\": 4, \"column\": 10 } },\n          \"message\": \"This component is created during render\"\n        },\n        {\n          \"kind\": \"error\",\n          \"loc\": { \"start\": { \"line\": 3, \"column\": 20 } },\n          \"message\": \"The component is created during render here\"\n        }\n      ]\n    }\n  }\n}\n```\n\n**Why it fails:** The `createComponent()` call creates a new component type on every render. When this component is used in JSX, React will see a different component type each time, causing the component to unmount and remount (losing all state) on every render.\n\n### Fixture: `static-components/invalid-dynamically-constructed-component-function.js`\n\n**Input:**\n```javascript\n// @validateStaticComponents\nfunction Example(props) {\n  const Component = () => <div />;\n  return <Component />;\n}\n```\n\n**Why it fails:** Even though this looks like a simple component definition, it creates a new function (and thus a new component type) on every render. The fix is to move the component definition outside of `Example`.\n"

    "content": "# validateSourceLocations\n\n## File\n`src/Validation/ValidateSourceLocations.ts`\n\n## Purpose\n**IMPORTANT: This validation is intended for unit tests only, not production use.**\n\nValidates that important source locations from the original code are preserved in the generated AST. This ensures that code coverage instrumentation tools (like Istanbul) can properly map back to the original source code for accurate coverage reports.\n\n## Input Invariants\n- Operates on the original Babel AST (`NodePath<FunctionDeclaration | ArrowFunctionExpression | FunctionExpression>`)\n- Operates on the generated CodegenFunction output\n- Must run after code generation\n\n## Validation Rules\nThe pass checks that \"important\" source locations (as defined by Istanbul's instrumentation requirements) are preserved in the generated output.\n\n### Two types of errors:\n\n1. **Missing location:**\n```\nImportant source location missing in generated code. Source location for [NodeType]\nis missing in the generated output. This can cause coverage instrumentation to fail\nto track this code properly, resulting in inaccurate coverage reports.\n```\n\n2. **Wrong node type:**\n```\nImportant source location has wrong node type in generated code. Source location for\n[ExpectedType] exists in the generated output but with wrong node type(s): [ActualTypes].\nThis can cause coverage instrumentation to fail to track this code properly.\n```\n\n### Important Node Types\nThe following node types are considered important for coverage tracking:\n```typescript\nconst IMPORTANT_INSTRUMENTED_TYPES = new Set([\n  'ArrowFunctionExpression',\n  'AssignmentPattern',\n  'ObjectMethod',\n  'ExpressionStatement',\n  'BreakStatement',\n  'ContinueStatement',\n  'ReturnStatement',\n  'ThrowStatement',\n  'TryStatement',\n  'VariableDeclarator',\n  'IfStatement',\n  'ForStatement',\n  'ForInStatement',\n  'ForOfStatement',\n  'WhileStatement',\n  'DoWhileStatement',\n  'SwitchStatement',\n  'SwitchCase',\n  'WithStatement',\n  'FunctionDeclaration',\n  'FunctionExpression',\n  'LabeledStatement',\n  'ConditionalExpression',\n  'LogicalExpression',\n  'VariableDeclaration',\n  'Identifier',\n]);\n```\n\n### Strict Node Types\nFor these types, both the location AND node type must match:\n- `VariableDeclaration`\n- `VariableDeclarator`\n- `Identifier`\n\n## Algorithm\n\n### Step 1: Collect Important Original Locations\nTraverse the original AST and collect locations from nodes whose types are in `IMPORTANT_INSTRUMENTED_TYPES`:\n- Skip nodes that are manual memoization calls (`useMemo`/`useCallback`) since the compiler intentionally removes these\n- Build a map from location key to `{loc, nodeTypes}`\n\n### Step 2: Collect Generated Locations\nRecursively traverse the generated AST (main function body + outlined functions) and collect all locations with their node types.\n\n### Step 3: Validate Preservation\nFor each important original location:\n- If the location is completely missing in generated output, report an error\n- For strict node types, verify the specific node type is present\n- Handle cases where a generated location has a different node type\n\n### Location Key Format\nLocations are compared using a string key:\n```typescript\nfunction locationKey(loc: SourceLocation): string {\n  return `${loc.start.line}:${loc.start.column}-${loc.end.line}:${loc.end.column}`;\n}\n```\n\n## Edge Cases\n\n### Manual Memoization Removal\nThe compiler intentionally removes `useMemo` and `useCallback` calls (replacing them with compiler-generated memoization). These are detected and exempted from validation:\n```typescript\nfunction isManualMemoization(node: Node): boolean {\n  // Checks for useMemo/useCallback or React.useMemo/React.useCallback\n}\n```\n\n### Outlined Functions\nThe validation also checks locations in outlined functions (functions extracted by the compiler for optimization purposes).\n\n### Multiple Node Types at Same Location\nMultiple node types can share the same location (e.g., a `VariableDeclarator` and its `Identifier` child). The pass tracks all node types for each location.\n\n## TODOs\nFrom the file documentation:\n> There's one big gotcha with this validation: it only works if the \"important\" original nodes are not optimized away by the compiler.\n>\n> When that scenario happens, we should just update the fixture to not include a node that has no corresponding node in the generated AST due to being completely removed during compilation.\n\n## Example\n\n### Fixture: `error.todo-missing-source-locations.js`\n\n**Input:**\n```javascript\n// @validateSourceLocations\nimport {useEffect, useCallback} from 'react';\n\nfunction Component({prop1, prop2}) {\n  const x = prop1 + prop2;\n  const y = x * 2;\n  const arr = [x, y];\n  const obj = {x, y};\n  let destA, destB;\n  if (y > 5) {\n    [destA, destB] = arr;\n  }\n\n  const [a, b] = arr;\n  const {x: c, y: d} = obj;\n  let sound;\n\n  if (y > 10) {\n    sound = 'woof';\n  } else {\n    sound = 'meow';\n  }\n\n  useEffect(() => {\n    if (a > 10) {\n      console.log(a);\n      console.log(sound);\n      console.log(destA, destB);\n    }\n  }, [a, sound, destA, destB]);\n\n  const foo = useCallback(() => {\n    return a + b;\n  }, [a, b]);\n\n  function bar() {\n    return (c + d) * 2;\n  }\n\n  console.log('Hello, world!');\n\n  return [y, foo, bar];\n}\n```\n\n**Error (partial):**\n```\nFound 25 errors:\n\nTodo: Important source location missing in generated code\nSource location for Identifier is missing in the generated output...\n\nerror.todo-missing-source-locations.ts:4:9\n> 4 | function Component({prop1, prop2}) {\n    |          ^^^^^^^^^\n\nTodo: Important source location missing in generated code\nSource location for VariableDeclaration is missing in the generated output...\n\nerror.todo-missing-source-locations.ts:9:2\n>  9 |   let destA, destB;\n     |   ^^^^^^^^^^^^^^^^^\n\nTodo: Important source location missing in generated code\nSource location for ExpressionStatement is missing in the generated output...\n\nerror.todo-missing-source-locations.ts:11:4\n> 11 |     [destA, destB] = arr;\n     |     ^^^^^^^^^^^^^^^^^^^^^\n```\n\n**Why it fails:** The compiler transforms the code significantly, and many original source locations are not preserved in the output. This causes coverage tools to lose track of which lines were executed.\n\n**Note:** This fixture is prefixed with `error.todo-` indicating this is a known limitation that needs to be addressed.\n"

analysis. Key types:\n\n- **HIRFunction**: A function being compiled\n  - `body.blocks`: Map of BasicBlocks (control flow graph)\n  - `context`: Captured variables from outer scope\n  - `params`: Function parameters\n  - `returns`: The function's return place\n\n- **BasicBlock**: A sequence of instructions with a terminal\n  - `instructions`: Array of Instructions\n  - `terminal`: Control flow (return, branch, etc.)\n  - `phis`: Phi nodes for SSA\n\n- **Instruction**: A single operation\n  - `lvalue`: The place being assigned to\n  - `value`: The instruction kind (CallExpression, FunctionExpression, etc.)\n  - `effects`: Array of AliasingEffects\n\n- **Place**: A reference to a value\n  - `identifier.id`: Unique IdentifierId\n  - `effect`: How the place is used (read, mutate, etc.)\n\n### ReactiveFunction\n\nAfter HIR is analyzed, it's converted to ReactiveFunction:\n\n- Tree structure instead of CFG\n- Contains ReactiveScopes that define memoization boundaries\n- Each scope has dependencies and declarations\n\n### AliasingEffects\n\nEffects describe data flow and operations:\n\n- **Capture/Alias**: Value relationships\n- **Mutate/MutateTransitive**: Mutation tracking\n- **Freeze**: Immutability marking\n- **Render**: JSX usage context\n- **Create/CreateFunction**: Value creation\n\n## Feature Flags\n\nMany passes are controlled by feature flags in `Environment.ts`:\n\n| Flag | Enables Pass |\n|------|--------------|\n| `enableJsxOutlining` | outlineJSX |\n| `enableFunctionOutlining` | outlineFunctions |\n| `validateNoSetStateInRender` | validateNoSetStateInRender |\n| `enableUseMemoCacheInterop` | Preserves manual memoization |\n\n## Running Tests\n\n```bash\n# Run all tests\nyarn snap\n\n# Run specific fixture\nyarn snap -p <fixture-name>\n\n# Run with debug output (shows all passes)\nyarn snap -p <fixture-name> -d\n\n# Compile any file (not just fixtures) and see output\nyarn snap compile <path>\n\n# Compile any file with debug output (alternative to yarn snap -d -p when you don't have a fixture)\nyarn snap compile --debug <path>\n\n# Minimize a failing test case to its minimal reproduction\nyarn snap minimize <path>\n\n# Update expected outputs\nyarn snap -u\n```\n\n## Fault Tolerance\n\nThe pipeline is fault-tolerant: all passes run to completion, accumulating errors on `Environment` rather than aborting on the first error.\n\n- **Validation passes** are wrapped in `env.tryRecord()` in Pipeline.ts, which catches non-invariant `CompilerError`s and records them. If a validation pass throws, compilation continues.\n- **Infrastructure/transformation passes** (enterSSA, eliminateRedundantPhi, inferMutationAliasingEffects, codegen, etc.) are NOT wrapped in `tryRecord()` because subsequent passes depend on their output being structurally valid. If they fail, compilation aborts.\n- **`lower()` (BuildHIR)** always produces an `HIRFunction`, recording errors on `env` instead of returning `Err`. Unsupported constructs (e.g., `var`) are lowered best-effort.\n- At the end of the pipeline, `env.hasErrors()` determines whether to return `Ok(codegen)` or `Err(aggregatedErrors)`.\n\n## Further Reading\n\n- [MUTABILITY_ALIASING_MODEL.md](../../src/Inference/MUTABILITY_ALIASING_MODEL.md): Detailed aliasing model docs\n- [Pipeline.ts](../../src/Entrypoint/Pipeline.ts): Pass ordering and orchestration\n- [HIR.ts](../../src/HIR/HIR.ts): Core data structure definitions\n"

Such functions (`someFunction()` in the example) could return different\n * values even though the function itself is the same object. This breaks memoization, since React relies on\n * the outer object (or function) changing if part of its value has changed.\n *\n * Given that we didn't have the Rules of React precisely documented prior to the introduction of React compiler,\n * it's understandable that some libraries accidentally shipped APIs that break this rule. However, developers\n * can easily run into pitfalls with these APIs. They may manually memoize them, which can break their app. Or\n * they may try using React Compiler, and think that the compiler has broken their code.\n *\n * To help ensure that developers can successfully use the compiler with existing code, this file teaches the\n * compiler about specific APIs that are known to be incompatible with memoization. We've tried to be as precise\n * as possible.\n *\n * The React team is open to collaborating with library authors to help develop compatible versions of these APIs,\n * and we have already reached out to the teams who own any API listed here to ensure they are aware of the issue.\n */\nexport function defaultModuleTypeProvider(\n  moduleName: string,\n): TypeConfig | null {\n  switch (moduleName) {\n    case 'react-hook-form': {\n      return {\n        kind: 'object',\n        properties: {\n          useForm: {\n            kind: 'hook',\n            returnType: {\n              kind: 'object',\n              properties: {\n                // Only the `watch()` function returned by react-hook-form's `useForm()` API is incompatible\n                watch: {\n                  kind: 'function',\n                  positionalParams: [],\n                  restParam: Effect.Read,\n                  calleeEffect: Effect.Read,\n                  returnType: {kind: 'type', name: 'Any'},\n                  returnValueKind: ValueKind.Mutable,\n                  knownIncompatible: `React Hook Form's \\`useForm()\\` API returns a \\`watch()\\` function which cannot be memoized safely.`,\n                },\n              },\n            },\n          },\n        },\n      };\n    }\n    case '@tanstack/react-table': {\n      return {\n        kind: 'object',\n        properties: {\n          /*\n           * Many of the properties of `useReactTable()`'s return value are incompatible, so we mark the entire hook\n           * as incompatible\n           */\n          useReactTable: {\n            kind: 'hook',\n            positionalParams: [],\n            restParam: Effect.Read,\n            returnType: {kind: 'type', name: 'Any'},\n            knownIncompatible: `TanStack Table's \\`useReactTable()\\` API returns functions that cannot be memoized safely`,\n          },\n        },\n      };\n    }\n    case '@tanstack/react-virtual': {\n      return {\n        kind: 'object',\n        properties: {\n          /*\n           * Many of the properties of `useVirtualizer()`'s return value are incompatible, so we mark the entire hook\n           * as incompatible\n           */\n          useVirtualizer: {\n            kind: 'hook',\n            positionalParams: [],\n            restParam: Effect.Read,\n            returnType: {kind: 'type', name: 'Any'},\n            knownIncompatible: `TanStack Virtual's \\`useVirtualizer()\\` API returns functions that cannot be memoized safely`,\n          },\n        },\n      };\n    }\n  }\n  return null;\n}\n"

These effects then form the basis for subsequent\n * analysis to determine the mutable range of each value in the program — the set of\n * instructions over which the value is created and mutated — as well as validation\n * against invalid code.\n *\n * At a high level the approach is:\n * - Determine a set of candidate effects based purely on the syntax of the instruction\n *   and the types involved. These candidate effects are cached the first time each\n *   instruction is visited. The idea is to reason about the semantics of the instruction\n *   or function in isolation, separately from how those effects may interact with later\n *   abstract interpretation.\n * - Then we do abstract interpretation over the HIR, iterating until reaching a fixpoint.\n *   This phase tracks the abstract kind of each value (mutable, primitive, frozen, etc)\n *   and the set of values pointed to by each identifier. Each candidate effect is \"applied\"\n *   to the current abtract state, and effects may be dropped or rewritten accordingly.\n *   For example, a \"MutateConditionally <x>\" effect may be dropped if x is not a mutable\n *   value. A \"Mutate <y>\" effect may get converted into a \"MutateFrozen <error>\" effect\n *   if y is mutable, etc.\n */\nexport function inferMutationAliasingEffects(\n  fn: HIRFunction,\n  {isFunctionExpression}: {isFunctionExpression: boolean} = {\n    isFunctionExpression: false,\n  },\n): void {\n  const initialState = InferenceState.empty(fn.env, isFunctionExpression);\n\n  // Map of blocks to the last (merged) incoming state that was processed\n  const statesByBlock: Map<BlockId, InferenceState> = new Map();\n\n  for (const ref of fn.context) {\n    // TODO: using InstructionValue as a bit of a hack, but it's pragmatic\n    const value: InstructionValue = {\n      kind: 'ObjectExpression',\n      properties: [],\n      loc: ref.loc,\n    };\n    initialState.initialize(value, {\n      kind: ValueKind.Context,\n      reason: new Set([ValueReason.Other]),\n    });\n    initialState.define(ref, value);\n  }\n\n  const paramKind: AbstractValue = isFunctionExpression\n    ?

We track whether each IdentifierId is reactive and terminate when\n * there are no changes after a given pass over the CFG.\n *\n * Note that in Forget it's possible to create a \"readonly\" reference to a value where\n * the reference is created within that value's mutable range:\n *\n * ```javascript\n * const x = [];\n * const z = [x];\n * x.push(props.input);\n *\n * return <div>{z}</div>;\n * ```\n *\n * Here `z` is never used to mutate the value, but it is aliasing `x` which\n * is mutated after the creation of the alias. The pass needs to account for\n * values which become reactive via mutability, and propagate this reactivity\n * to these readonly aliases. Using forward data flow is insufficient since\n * this information needs to propagate \"backwards\" from the `x.push(props.input)`\n * to the previous `z = [x]` line.

    "content": "# The Mutability & Aliasing Model\n\nThis document describes the new (as of June 2025) mutability and aliasing model powering React Compiler. The mutability and aliasing system is a conceptual subcomponent whose primary role is to determine minimal sets of values that mutate together, and the range of instructions over which those mutations occur. These minimal sets of values that mutate together, and the corresponding instructions doing those mutations, are ultimately grouped into reactive scopes, which then translate into memoization blocks in the output (after substantial additional processing described in the comments of those passes).\n\nTo build an intuition, consider the following example:\n\n```js\nfunction Component() {\n    // a is created and mutated over the course of these two instructions:\n    const a = {};\n    mutate(a);\n\n    // b and c are created and mutated together — mutate might modify b via c\n    const b = {};\n    const c = {b};\n    mutate(c);\n\n    // does not modify a/b/c\n    return <Foo a={a} c={c} />\n}\n```\n\nThe goal of mutability and aliasing inference is to understand the set of instructions that create/modify a, b, and c.\n\nIn code, the mutability and aliasing model is compromised of the following phases:\n\n* `InferMutationAliasingEffects`. Infers a set of mutation and aliasing effects for each instruction. The approach is to generate a set of candidate effects based purely on the semantics of each instruction and the types of the operands, then use abstract interpretation to determine the actual effects (or errors) that would apply. For example, an instruction that by default has a Capture effect might downgrade to an ImmutableCapture effect if the value is known to be frozen.\n* `InferMutationAliasingRanges`. Infers a mutable range (start:end instruction ids) for each value in the program, and annotates each Place with its effect type for usage in later passes. This builds a graph of data flow through the program over time in order to understand which mutations effect which values.\n* `InferReactiveScopeVariables`. Given the per-Place effects, determines disjoint sets of values that mutate together and assigns all identifiers in each set to a unique scope, and updates the range to include the ranges of all constituent values.\n\nFinally, `AnalyzeFunctions` needs to understand the mutation and aliasing semantics of nested FunctionExpression and ObjectMethod values. `AnalyzeFunctions` calls `InferFunctionExpressionAliasingEffectsSignature` to determine the publicly observable set of mutation/aliasing effects for nested functions.\n\n## Mutation and Aliasing Effects\n\nThe inference model is based on a set of \"effects\" that describe subtle aspects of mutation, aliasing, and other changes to the state of values over time\n\n### Creation Effects\n\n#### Create\n\n```js\n{\n    kind: 'Create';\n    into: Place;\n    value: ValueKind;\n    reason: ValueReason;\n}\n```\n\nDescribes the creation of a new value with the given kind, and reason for having that kind. For example, `x = 10` might have an effect like `Create x = ValueKind.Primitive [ValueReason.Other]`.\n\n#### CreateFunction\n\n```js\n{\n    kind: 'CreateFunction';\n    captures: Array<Place>;\n    function: FunctionExpression | ObjectMethod;\n    into: Place;\n}\n```\n\nDescribes the creation of new function value, capturing the given set of mutable values. CreateFunction is used to specifically track function types so that we can precisely model calls to those functions with `Apply`.\n\n#### Apply\n\n```js\n{\n    kind: 'Apply';\n    receiver: Place;\n    function: Place; // same as receiver for function calls\n    mutatesFunction: boolean; // indicates if this is a type that we consider to mutate the function itself by default\n    args: Array<Place | SpreadPattern | Hole>;\n    into: Place; // where result is stored\n    signature: FunctionSignature | null;\n}\n```\n\nDescribes the potential creation of a value by calling a function. This models `new`, function calls, and method calls. The inference algorithm uses the most precise signature it can determine:\n\n* If the function is a locally created function expression, we use a signature inferred from the behavior of that function to interpret the effects of calling it with the given arguments.\n* Else if the function has a known aliasing signature (new style precise effects signature), we apply the arguments to that signature to get a precise set of effects.\n* Else if the function has a legacy style signature (with per-param effects) we convert the legacy per-Place effects into aliasing effects (described in this doc) and apply those.\n* Else fall back to inferring a generic set of effects.\n\nThe generic fallback is to assume:\n- The return value may alias any of the arguments (Alias param -> return)\n- Any arguments *may* be transitively mutated (MutateTransitiveConditionally param)\n- Any argument may be captured into any other argument (Capture paramN -> paramM for all N,M where N != M)\n\n### Aliasing Effects\n\nThese effects describe data-flow only, separately from mutation or other state-changing semantics.\n\n#### Assign\n\n```js\n{\n    kind: 'Assign';\n    from: Place;\n    into: Place;\n}\n```\n\nDescribes an `x = y` assignment, where the receiving (into) value is overwritten with a new (from) value. After this effect, any previous assignments/aliases to the receiving value are dropped. Note that `Alias` initializes the receiving value.\n\n> TODO: InferMutationAliasingRanges may not fully reset aliases on encountering this effect\n\n#### Alias\n\n```js\n{\n    kind: 'Alias';\n    from: Place;\n    into: Place;\n}\n```\n\nDescribes that an assignment _may_ occur, but that the possible assignment is non-exclusive. The canonical use-case for `Alias` is a function that may return more than one of its arguments, such as `(x, y, z) => x ? y : z`. Here, the result of this function may be `y` or `z`, but neither one overwrites the other. Note that `Alias` does _not_ initialize the receiving value: it should always be paired with an effect to create the receiving value.\n\n#### Capture\n\n```js\n{\n    kind: 'Capture';\n    from: Place;\n    into: Place;\n}\n```\n\nDescribes that a reference to one variable (from) is stored within another value (into). Examples include:\n- An array expression captures the items of the array (`array = [capturedValue]`)\n- Array.prototype.push captures the pushed values into the array (`array.push(capturedValue)`)\n- Property assignment captures the value onto the object (`object.property = capturedValue`)\n\n#### CreateFrom\n\n```js\n{\n    kind: 'CreateFrom';\n    from: Place;\n    into: Place;\n}\n```\n\nThis is somewhat the inverse of `Capture`. The `CreateFrom` effect describes that a variable is initialized by extracting _part_ of another value, without taking a direct alias to the full other value. Examples include:\n\n- Indexing into an array (`createdFrom = array[0]`)\n- Reading an object property (`createdFrom = object.property`)\n- Getting a Map key (`createdFrom = map.get(key)`)\n\n#### ImmutableCapture\n\nDescribes immutable data flow from one value to another. This is not currently used for anything, but is intended to eventually power a more sophisticated escape analysis.\n\n### MaybeAlias\n\nDescribes potential data flow that the compiler knows may occur behind a function call, but cannot be sure about. For example, `foo(x)` _may_ be the identity function and return `x`, or `cond(a, b, c)` may conditionally return `b` or `c` depending on the value of `a`, but those functions could just as easily return new mutable values and not capture any information from their arguments. MaybeAlias represents that we have to consider the potential for data flow when deciding mutable ranges, but should be conservative about reporting errors. For example, `foo(someFrozenValue).property = true` should not error since we don't know for certain that foo returns its input.\n\n### State-Changing Effects\n\nThe following effects describe state changes to specific values, not data flow. In many cases, JavaScript semantics will involve a combination of both data-flow effects *and* state-change effects. For example, `object.property = value` has data flow (`Capture object <- value`) and mutation (`Mutate object`).\n\n#### Freeze\n\n```js\n{\n    kind: 'Freeze',\n    // The reference being frozen\n    value: Place;\n    // The reason the value is frozen (passed to a hook, passed to jsx, etc)\n    reason: ValueReason;\n}\n```\n\nOnce a reference to a value has been passed to React, that value is generally not safe to mutate further. This is not a strictly required property of React, but is a natural consequence of making components and hooks composable without leaking implementation details. Concretely, once a value has been passed as a JSX prop, passed as argument to a hook, or returned from a hook, it must be assumed that the other \"side\" — receiver of the prop/argument/return value — will use that value as an input to an effect or memoization unit. Mutating that value (instead of creating a new value) will fail to cause the consuming computation to update:\n\n```js\n// INVALID DO NOT DO THIS\nfunction Component(props) {\n    const array = useArray(props.value);\n    // OOPS! this value is memoized, the array won't get re-created\n    // when `props.value` changes, so we might just keep pushing new\n    // values to the same array on every render!\n    array.push(props.otherValue);\n}\n\nfunction useArray(a) {\n    return useMemo(() => [a], [a]);\n}\n```\n\nThe **Freeze** effect accepts a variable reference and a reason that the value is being frozen. Note: _freeze only applies to the reference, not the underlying value_. Our inference is conservative, and assumes that there may still be other references to the same underlying value which are mutated later. For example:\n\n```js\nconst x = {};\nconst y = [];\nx.y = y;\nfreeze(y); // y _reference_ is frozen\nx.y.push(props.value); // but y is still considered mutable bc of this\n```\n\n#### Mutate (and MutateConditionally)\n\n```js\n{\n    kind: 'Mutate';\n    value: Place;\n}\n```\n\nMutate indicates that a value is mutated, without modifying any of the values that it may transitively have captured. Canonical examples include:\n\n- Pushing an item onto an array modifies the array, but does not modify any items stored _within_ the array (unless the array has a reference to itself!)\n- Assigning a value to an object property modifies the object, but not any values stored in the object's other properties.\n\nThis helps explain the distinction between Assign/Alias and Capture: Mutate only affects assign/alias but not captures.\n\n`MutateConditionally` is an alternative in which the mutation _may_ happen depending on the type of the value. The conditional variant is not generally used and included for completeness.\n\n\n\n#### MutateTransitiveConditionally (and MutateTransitive)\n\n`MutateTransitiveConditionally` represents an operation that may mutate _any_ aspect of a value, including reaching arbitrarily deep into nested values to mutate them. This is the default semantic for unknown functions — we have no idea what they do, so we assume that they are idempotent but may mutate any aspect of the mutable values that are passed to them.\n\nThere is also `MutateTransitive` for completeness, but this is not generally used.\n\n### Side Effects\n\nFinally, there are a few effects that describe error, or potential error, conditions:\n\n- `MutateFrozen` is always an error, because it indicates known mutation of a value that should not be mutated.\n- `MutateGlobal` indicates known mutation of a global value, which is not safe during render. This effect is an error if reachable during render, but allowed if only reachable via an event handler or useEffect.\n- `Impure` indicates calling some other logic that is impure/side-effecting. This is an error if reachable during render, but allowed if only reachable via an event handler or useEffect.\n  - TODO: we could probably merge this and MutateGlobal\n- `Render` indicates a value that is not mutated, but is known to be called during render. It's used for a few particular places like JSX tags and JSX children, which we assume are accessed during render (while other props may be event handlers etc). This helps to detect more MutateGlobal/Impure effects and reject more invalid programs.\n\n\n## Rules\n\n### Mutation of Alias Mutates the Source Value\n\n```\nAlias a <- b\nMutate a\n=>\nMutate b\n```\n\nExample:\n\n```js\nconst a = maybeIdentity(b); // Alias a <- b\na.property = value; // a could be b, so this mutates b\n```\n\n### Mutation of Assignment Mutates the Source Value\n\n```\nAssign a <- b\nMutate a\n=>\nMutate b\n```\n\nExample:\n\n```js\nconst a = b;\na.property = value // a _is_ b, this mutates b\n```\n\n### Mutation of CreateFrom Mutates the Source Value\n\n```\nCreateFrom a <- b\nMutate a\n=>\nMutate b\n```\n\nExample:\n\n```js\nconst a = b[index];\na.property = value // the contents of b are transitively mutated\n```\n\n\n### Mutation of Capture Does *Not* Mutate the Source Value\n\n```\nCapture a <- b\nMutate a\n!=>\n~Mutate b~\n```\n\nExample:\n\n```js\nconst a = {};\na.b = b;\na.property = value; // mutates a, not b\n```\n\n### Mutation of Source Affects Alias, Assignment, CreateFrom, and Capture\n\n```\nAlias a <- b OR Assign a <- b OR CreateFrom a <- b OR Capture a <- b\nMutate b\n=>\nMutate a\n```\n\nA derived value changes when it's source value is mutated.\n\nExample:\n\n```js\nconst x = {};\nconst y = [x];\nx.y = true; // this changes the value within `y` ie mutates y\n```\n\n\n### TransitiveMutation of Alias, Assignment, CreateFrom, or Capture Mutates the Source\n\n```\nAlias a <- b OR Assign a <- b OR CreateFrom a <- b OR Capture a <- b\nMutateTransitive a\n=>\nMutateTransitive b\n```\n\nRemember, the intuition for a transitive mutation is that it's something that could traverse arbitrarily deep into an object and mutate whatever it finds. Imagine something that recurses into every nested object/array and sets `.field = value`. Given a function `mutate()` that does this, then:\n\n```js\nconst a = b; // assign\nmutate(a); // clearly can transitively mutate b\n\nconst a = maybeIdentity(b); // alias\nmutate(a); // clearly can transitively mutate b\n\nconst a = b[index]; // createfrom\nmutate(a); // clearly can transitively mutate b\n\nconst a = {};\na.b = b; // capture\nmutate(a); // can transitively mutate b\n```\n\n### MaybeAlias makes mutation conditional\n\nBecause we don't know for certain that the aliasing occurs, we consider the mutation conditional against the source.\n\n```\nMaybeAlias a <- b\nMutate a\n=>\nMutateConditional b\n```\n\n### Freeze Does Not Freeze the Value\n\nFreeze does not freeze the value itself:\n\n```\nCreate x\nAssign y <- x OR Alias y <- x OR CreateFrom y <- x OR Capture y <- x\nFreeze y\n!=>\n~Freeze x~\n```\n\nThis means that subsequent mutations of the original value are valid:\n\n```\nCreate x\nAssign y <- x OR Alias y <- x OR CreateFrom y <- x OR Capture y <- x\nFreeze y\nMutate x\n=>\nMutate x (mutation is ok)\n```\n\nAs well as mutations through other assignments/aliases/captures/createfroms of the original value:\n\n```\nCreate x\nAssign y <- x OR Alias y <- x OR CreateFrom y <- x OR Capture y <- x\nFreeze y\nAlias z <- x OR Capture z <- x OR CreateFrom z <- x OR Assign z <- x\nMutate z\n=>\nMutate x (mutation is ok)\n```\n\n### Freeze Freezes The Reference \n\nAlthough freeze doesn't freeze the value, it does affect the reference. The reference cannot be used to mutate.\n\nConditional mutations of the reference are no-ops:\n\n```\nCreate x\nAssign y <- x OR Alias y <- x OR CreateFrom y <- x OR Capture y <- x\nFreeze y\nMutateConditional y\n=>\n(no mutation)\n```\n\nAnd known mutations of the reference are errors:\n\n```\nCreate x\nAssign y <- x OR Alias y <- x OR CreateFrom y <- x OR Capture y <- x\nFreeze y\nMutateConditional y\n=>\nMutateFrozen y error=...\n```\n\n### Corollary: Transitivity of Assign/Alias/CreateFrom/Capture\n\nA key part of the inference model is inferring a signature for function expressions. The signature is a minimal set of effects that describes the publicly observable behavior of the function. This can include \"global\" effects like side effects (MutateGlobal/Impure) as well as mutations/aliasing of parameters and free variables.\n\nIn order to determine the aliasing of params and free variables into each other and/or the return value, we may encounter chains of assign, alias, createfrom, and capture effects. For example:\n\n```js\nconst f = (x) => {\n    const y = [x];  // capture y <- x\n    const z = y[0]; // createfrom z <- y\n    return z;     // assign return <- z\n}\n// <Effect> return <- x\n```\n\nIn this example we can see that there should be some effect on `f` that tracks the flow of data from `x` into the return value. The key constraint is preserving the semantics around how local/transitive mutations of the destination would affect the source.\n\n#### Each of the effects is transitive with itself\n\n```\nAssign b <- a\nAssign c <- b\n=>\nAssign c <- a\n```\n\n```\nAlias b <- a\nAlias c <- b\n=>\nAlias c <- a\n```\n\n```\nCreateFrom b <- a\nCreateFrom c <- b\n=>\nCreateFrom c <- a\n```\n\n```\nCapture b <- a\nCapture c <- b\n=>\nCapture c <- a\n```\n\n#### Alias > Assign\n\n```\nAssign b <- a\nAlias c <- b\n=>\nAlias c <- a\n```\n\n```\nAlias b <- a\nAssign c <- b\n=>\nAlias c <- a\n```\n\n### CreateFrom > Assign/Alias\n\nIntuition: \n\n```\nCreateFrom b <- a\nAlias c <- b OR Assign c <- b\n=>\nCreateFrom c <- a\n```\n\n```\nAlias b <- a OR Assign b <- a\nCreateFrom c <- b\n=>\nCreateFrom c <- a\n```\n\n### Capture > Assign/Alias\n\nIntuition: capturing means that a local mutation of the destination will not affect the source, so we preserve the capture.\n\n```\nCapture b <- a\nAlias c <- b OR Assign c <- b\n=>\nCapture c <- a\n```\n\n```\nAlias b <- a OR Assign b <- a\nCapture c <- b\n=>\nCapture c <- a\n```\n\n### Capture And CreateFrom\n\nIntuition: these effects are inverses of each other (capturing into an object, extracting from an object). The result is based on the order of operations:\n\nCapture then CreateFrom is equivalent to Alias: we have to assume that the result _is_ the original value and that a local mutation of the result could mutate the original.\n\n```js\nconst b = [a]; // capture\nconst c = b[0]; // createfrom\nmutate(c); // this clearly can mutate a, so the result must be one of Assign/Alias/CreateFrom \n```\n\nWe use Alias as the return type because the mutability kind of the result is not derived from the source value (there's a fresh object in between due to the capture), so the full set of effects in practice would be a Create+Alias.\n\n```\nCapture b <- a\nCreateFrom c <- b\n=>\nAlias c <- a\n```\n\nMeanwhile the opposite direction preserves the capture, because the result is not the same as the source:\n\n```js\nconst b = a[0]; // createfrom\nconst c = [b]; // capture\nmutate(c); // does not mutate a, so the result must be Capture\n```\n\n```\nCreateFrom b <- a\nCapture c <- b\n=>\nCapture c <- a\n```"

First, we only merge\n * scopes that are in the same (reactive) block, ie we don't merge across\n * control-flow or block-scoping boundaries. Second, we can only merge scopes\n * so long as any intermediate instructions are safe to memoize — specifically,\n * as long as the values created by those instructions are only referenced by\n * the second scope and not elsewhere. This is to avoid changing control-flow\n * and to avoid increasing the number of scope outputs (which defeats the optimization).\n *\n * With that in mind we can apply the optimization in two cases. Given a block with\n * scope A, some safe-to-memoize instructions I, and scope B, we can merge scopes when:\n * - A and B have identical dependencies. This means they will invalidate together, so\n *    by merging the scopes we can avoid duplicate cache slots and duplicate checks of\n *    those dependencies.\n * - The output of A is the input to B. Any invalidation of A will change its output\n *    which invalidates B, so we can similarly merge scopes. Note that this optimization\n *    may not be beneficial if the outupts of A are not guaranteed to change if its input\n *    changes, but in practice this is generally the case.\n *\n * ## Nested Scopes\n *\n * In this case, if an inner scope has the same dependencies as its parent, then we can\n * flatten away the inner scope since it will always invalidate at the same time.\n *\n * Note that PropagateScopeDependencies propagates scope dependencies upwards. This ensures\n * that parent scopes have the union of their own direct dependencies as well as those of\n * their (transitive) children. As a result nested scopes may have the same or fewer\n * dependencies than their parents, but not more dependencies.

Specifically, if a reactive\n * scope early returned during the previous execution and the inputs to that block\n * have not changed, then the code should early return (with the same value) again.\n *\n * Example:\n *\n * ```javascript\n * let x = [];\n * if (props.cond) {\n *   x.push(12);\n *   return x;\n * } else {\n *   return foo();\n * }\n * ```\n *\n * Imagine that this code is called twice in a row with props.cond = true. Both\n * times it should return the same object (===), an array `[12]`.\n *\n * The compilation strategy is as follows. For each top-level reactive scope\n * that contains (transitively) an early return:\n *\n * - Label the scope\n * - Synthesize a new temporary, eg `t0`, and set it as a declaration of the scope.\n *   This will represent the possibly-unset return value for that scope.\n * - Make the first instruction of the scope the declaration of that temporary,\n *   assigning a sentinel value (can reuse the same symbol as we use for cache slots).\n *   This assignment ensures that if we don't take an early return, that the value\n *   is the sentinel.\n * - Replace all `return` statements with:\n *   - An assignment of the temporary with the value being returned.\n *   - A `break` to the reactive scope's label.\n *\n * Finally, CodegenReactiveScope adds an if check following the reactive scope:\n * if the early return temporary value is *not* the sentinel value, we early return\n * it. Otherwise, execution continues.\n *\n * For the above example that looks roughly like:\n *\n * ```\n * let t0;\n * if (props.cond !== $[0]) {\n *   t0 = Symbol.for('react.memo_cache_sentinel');\n *   bb0: {\n *     let x = [];\n *     if (props.cond) {\n *       x.push(12);\n *       t0 = x;\n *       break bb0;\n *     } else {\n *       let t1;\n *       if ($[1] === Symbol.for('react.memo_cache_sentinel')) {\n *         t1 = foo();\n *         $[1] = t1;\n *       } else {\n *         t1 = $[1];\n *       }\n *       t0 = t1;\n *       break bb0;\n *     }\n *   }\n *   $[0] = props.cond;\n *   $[2] = t0;\n * } else {\n *   t0 = $[2];\n * }\n * // This part added in CodegenReactiveScope:\n * if (t0 !== Symbol.for('react.memo_cache_sentinel')) {\n *   return t0;\n * }\n * ```\n */\nexport function propagateEarlyReturns(fn: ReactiveFunction): void {\n  visitReactiveFunction(fn, new Transform(fn.env), {\n    withinReactiveScope: false,\n    earlyReturnValue: null,\n  });\n}\n\ntype State = {\n  /**\n   * Are we within a reactive scope?

Values can\n * escape in one of two ways:\n * * They are directly returned by the function and/or transitively aliased by a return\n *    value.\n * * They are passed as input to a hook. This is because any value passed to a hook may\n *    have its referenced ultimately stored by React (ie, be aliased by an external value).\n *    For example, the closure passed to useEffect escapes.\n *\n * Example to build intuition:\n *\n * ```javascript\n * function Component(props) {\n *    const a = {}; // not aliased or returned: *not* memoized\n *    const b = {}; // aliased by c, which is returned: memoized\n *    const c = [b]; // directly returned: memoized\n *    return c;\n * }\n * ```\n *\n * However, this logic alone is insufficient for two reasons:\n * - Statically memoizing JSX elements *may* be inefficient compared to using dynamic\n *    memoization with `React.memo()`. Static memoization may be JIT'd and can look at\n *    the precise props w/o dynamic iteration, but incurs potentially large code-size\n *    overhead. Dynamic memoization with `React.memo()` incurs potentially increased\n *    runtime overhead for smaller code size. We plan to experiment with both variants\n *    for JSX.\n * - Because we merge values whose mutations _interleave_ into a single scope, there\n *    can be cases where a non-escaping value needs to be memoized anyway to avoid breaking\n *    a memoization input. As a rule, for any scope that has a memoized output, all of that\n *    scope's transitive dependencies must also be memoized _even if they don't escape_.\n *    Failing to memoize them would cause the scope to invalidate more often than necessary\n *    and break downstream memoization.\n *\n * Example of this second case:\n *\n * ```javascript\n * function Component(props) {\n *    // a can be independently memoized but it doesn't escape, so naively we may think its\n *    // safe to not memoize. but not memoizing would break caching of b, which does\n *    // escape.\n *    const a = [props.a];\n *\n *    // b and c are interleaved and grouped into a single scope,\n *    // but they are independent values. c does not escape, but\n *    // we need to ensure that a is memoized or else b will invalidate\n *    // on every render since a is a dependency.\n *    const b = [];\n *    const c = {};\n *    c.a = a;\n *    b.push(props.b);\n *\n *    return b;\n * }\n * ```\n *\n * ## Algorithm\n *\n * 1. First we build up a graph, a mapping of IdentifierId to a node describing all the\n *     scopes and inputs involved in creating that identifier. Individual nodes are marked\n *     as definitely aliased, conditionally aliased, or unaliased:\n *       a. Arrays, objects, function calls all produce a new value and are always marked as aliased\n *       b. Conditional and logical expressions (and a few others) are conditinally aliased,\n *          depending on whether their result value is aliased.\n *       c. JSX is always unaliased (though its props children may be)\n * 2.

The goal of the validation is to ensure\n * that auto-memoization will not substantially change the behavior of\n * the program:\n * - If the manual dependencies were non-exhaustive (missing important deps)\n *   then auto-memoization will include those dependencies, and cause the\n *   value to update *more* frequently.\n * - If the manual dependencies had extraneous deps, then auto memoization\n *   will remove them and cause the value to update *less* frequently.\n *\n * The implementation compares the manual dependencies against the values\n * actually used within the memoization function\n * - For each value V referenced in the memo function, either:\n *   - If the value is non-reactive *and* a known stable type, then the\n *     value may optionally be specified as an exact dependency.\n *   - Otherwise, report an error unless there is a manual dependency that will\n *     invalidate whenever V invalidates. If `x.y.z` is referenced, there must\n *     be a manual dependency for `x.y.z`, `x.y`, or `x`. Note that we assume\n *     no interior mutability, ie we assume that any changes to inner paths must\n *     always cause the other path to change as well.\n * - Any dependencies that do not correspond to a value referenced in the memo\n *   function are considered extraneous and throw an error\n *\n * ## TODO: Invalid, Complex Deps\n *\n * Handle cases where the user deps were not simple identifiers + property chains.\n * We try to detect this in ValidateUseMemo but we miss some cases. The problem\n * is that invalid forms can be value blocks or function calls that don't get\n * removed by DCE, leaving a structure like:\n *\n * StartMemoize\n * t0 = <value to memoize>\n * ...non-DCE'd code for manual deps...\n * FinishMemoize decl=t0\n *\n * When we go to compute the dependencies, we then think that the user's manual dep\n * logic is part of what the memo computation logic.\n */\nexport function validateExhaustiveDependencies(fn: HIRFunction): void {\n  const env = fn.env;\n  const reactive = collectReactiveIdentifiersHIR(fn);\n\n  const temporaries: Map<IdentifierId, Temporary> = new Map();\n  for (const param of fn.params) {\n    const place = param.kind === 'Identifier' ? param : param.place;\n    temporaries.set(place.identifier.id, {\n      kind: 'Local',\n      identifier: place.identifier,\n      path: [],\n      context: false,\n      loc: place.loc,\n    });\n  }\n  let startMemo: StartMemoize | null = null;\n\n  function onStartMemoize(\n    value: StartMemoize,\n    dependencies: Set<InferredDependency>,\n    locals: Set<IdentifierId>,\n  ): void {\n    CompilerError.invariant(startMemo == null, {\n      reason: 'Unexpected nested memo calls',\n      loc: value.loc,\n    });\n    startMemo = value;\n    dependencies.clear();\n    locals.clear();\n  }\n  function onFinishMemoize(\n    value: FinishMemoize,\n    dependencies: Set<InferredDependency>,\n    locals: Set<IdentifierId>,\n  ): void {\n    CompilerError.invariant(\n      startMemo != null && startMemo.manualMemoId === value.manualMemoId,\n      {\n        reason: 'Found FinishMemoize without corresponding StartMemoize',\n        loc: value.loc,\n      },\n    );\n    if (env.config.validateExhaustiveMemoizationDependencies) {\n      visitCandidateDependency(value.decl, temporaries, dependencies, locals);\n      const inferred: Array<InferredDependency> = Array.from(dependencies);\n\n      const diagnostic = validateDependencies(\n        inferred,\n        startMemo.deps ??

Dependencies are collected eagerly, the first time an\n * external variable is referenced, as opposed to trying to delay or aggregate\n * calculation of dependencies until they are later \"used\".\n *\n * For example, in\n *\n * ```\n * function f() {\n *   let x = y; // we record a dependency on `y` here\n *   ...\n *   use(x); // as opposed to trying to delay that dependency until here\n * }\n * ```\n *\n * That said, LoadLocal/LoadContext does not immediately take a dependency,\n * we store the dependency in a temporary and set it as used when that temporary\n * is referenced as an operand.\n *\n * As we proceed through the function we track local variables that it creates\n * and don't consider later references to these variables as dependencies.\n *\n * For function expressions we first collect the function's dependencies by\n * calling this function recursively, _without_ taking into account whether\n * the \"external\" variables it accesses are actually external or just locals\n * in the parent. We then prune any locals and immediately consider any\n * remaining externals that it accesses as a dependency:\n *\n * ```\n * function Component() {\n *   const local = ...;\n *   const f = () => { return [external, local] };\n * }\n * ```\n *\n * Here we calculate `f` as having dependencies `external, `local` and save\n * this into `temporaries`. We then also immediately take these as dependencies\n * at the Component scope, at which point we filter out `local` as a local variable,\n * leaving just a dependency on `external`.\n *\n * When calling this function on a top-level component or hook, the collected dependencies\n * will only contain the globals that it accesses which isn't useful. Instead, passing\n * onStartMemoize/onFinishMemoize callbacks allows looking at the dependencies within\n * blocks of manual memoization.\n */\nfunction collectDependencies(\n  fn: HIRFunction,\n

You can omit the `eslint-plugin-` prefix:\n\n```json\n{\n    \"plugins\": [\n        \"react-compiler\"\n    ]\n}\n```\n\n\nThen configure the rules you want to use under the rules section.\n\n```json\n{\n    \"rules\": {\n        \"react-compiler/react-compiler\": \"error\"\n    }\n}\n```\n\n## Rules\n\n<!-- begin auto-generated rules list -->\nTODO: Run eslint-doc-generator to generate the rules list.\n<!-- end auto-generated rules list -->\n"

You will need to restart Claude everytime you want to try your changes.\n"

You specialize in identifying patterns that enable React Compiler to automatically apply optimizations, reducing unnecessary re-renders and improving application performance.\n\n## Follow these guidelines in all code you produce and suggest\nUse functional components with Hooks: Do not generate class components or use old lifecycle methods. Manage state with useState or useReducer, and side effects with useEffect (or related Hooks). Always prefer functions and Hooks for any new component logic.\n\nKeep components pure and side-effect-free during rendering: Do not produce code that performs side effects (like subscriptions, network requests, or modifying external variables) directly inside the component's function body. Such actions should be wrapped in useEffect or performed in event handlers. Ensure your render logic is a pure function of props and state.\n\nRespect one-way data flow: Pass data down through props and avoid any global mutations. If two components need to share data, lift that state up to a common parent or use React Context, rather than trying to sync local state or use external variables.\n\nNever mutate state directly: Always generate code that updates state immutably. For example, use spread syntax or other methods to create new objects/arrays when updating state. Do not use assignments like state.someValue = ... or array mutations like array.push() on state variables. Use the state setter (setState from useState, etc.) to update state.\n\nAccurately use useEffect and other effect Hooks: whenever you think you could useEffect, think and reason harder to avoid it. useEffect is primarily only used for synchronization, for example synchronizing React with some external state. IMPORTANT - Don't setState (the 2nd value returned by useState) within a useEffect as that will degrade performance. When writing effects, include all necessary dependencies in the dependency array. Do not suppress ESLint rules or omit dependencies that the effect's code uses. Structure the effect callbacks to handle changing values properly (e.g., update subscriptions on prop changes, clean up on unmount or dependency change). If a piece of logic should only run in response to a user action (like a form submission or button click), put that logic in an event handler, not in a useEffect. Where possible, useEffects should return a cleanup function.\n\nFollow the Rules of Hooks: Ensure that any Hooks (useState, useEffect, useContext, custom Hooks, etc.) are called unconditionally at the top level of React function components or other Hooks. Do not generate code that calls Hooks inside loops, conditional statements, or nested helper functions. Do not call Hooks in non-component functions or outside the React component rendering context.\n\nUse refs only when necessary: Avoid using useRef unless the task genuinely requires it (such as focusing a control, managing an animation, or integrating with a non-React library). Do not use refs to store application state that should be reactive. If you do use refs, never write to or read from ref.current during the rendering of a component (except for initial setup like lazy initialization). Any ref usage should not affect the rendered output directly.\n\nPrefer composition and small components: Break down UI into small, reusable components rather than writing large monolithic components. The code you generate should promote clarity and reusability by composing components together. Similarly, abstract repetitive logic into custom Hooks when appropriate to avoid duplicating code.\n\nOptimize for concurrency: Assume React may render your components multiple times for scheduling purposes (especially in development with Strict Mode). Write code that remains correct even if the component function runs more than once. For instance, avoid side effects in the component body and use functional state updates (e.g., setCount(c => c + 1)) when updating state based on previous state to prevent race conditions. Always include cleanup functions in effects that subscribe to external resources. Don't write useEffects for \"do this when this changes\" side-effects. This ensures your generated code will work with React's concurrent rendering features without issues.\n\nOptimize to reduce network waterfalls - Use parallel data fetching wherever possible (e.g., start multiple requests at once rather than one after another). Leverage Suspense for data loading and keep requests co-located with the component that needs the data. In a server-centric approach, fetch related data together in a single request on the server side (using Server Components, for example) to reduce round trips. Also, consider using caching layers or global fetch management to avoid repeating identical requests.\n\nRely on React Compiler - useMemo, useCallback, and React.memo can be omitted if React Compiler is enabled. Avoid premature optimization with manual memoization. Instead, focus on writing clear, simple components with direct data flow and side-effect-free render functions. Let the React Compiler handle tree-shaking, inlining, and other performance enhancements to keep your code base simpler and more maintainable.\n\nDesign for a good user experience - Provide clear, minimal, and non-blocking UI states. When data is loading, show lightweight placeholders (e.g., skeleton screens) rather than intrusive spinners everywhere. Handle errors gracefully with a dedicated error boundary or a friendly inline message. Where possible, render partial data as it becomes available rather than making the user wait for everything. Suspense allows you to declare the loading states in your component tree in a natural way, preventing “flash” states and improving perceived performance.\n\nServer Components - Shift data-heavy logic to the server whenever possible. Break up the more static parts of the app into server components. Break up data fetching into server components. Only client components (denoted by the 'use client' top level directive) need interactivity. By rendering parts of your UI on the server, you reduce the client-side JavaScript needed and avoid sending unnecessary data over the wire. Use Server Components to prefetch and pre-render data, allowing faster initial loads and smaller bundle sizes. This also helps manage or eliminate certain waterfalls by resolving data on the server before streaming the HTML (and partial React tree) to the client.\n\n## Available Tools\n- 'docs': Look up documentation from react.dev. Returns text as a string.\n- 'compile': Run the user's code through React Compiler. Returns optimized JS/TS code with potential diagnostics.\n\n## Process\n1. Analyze the user's code for optimization opportunities:\n   - Check for React anti-patterns that prevent compiler optimization\n   - Identify unnecessary manual optimizations (useMemo, useCallback, React.memo) that the compiler can handle\n   - Look for component structure issues that limit compiler effectiveness\n   - Think about each suggestion you are making and consult React docs using the docs://{query} resource for best practices\n\n2. Use React Compiler to verify optimization potential:\n   - Run the code through the compiler and analyze the output\n   - You can run the compiler multiple times to verify your work\n   - Check for successful optimization by looking for const $ = _c(n) cache entries, where n is an integer\n   - Identify bailout messages that indicate where code could be improved\n   - Compare before/after optimization potential\n\n3. Provide actionable guidance:\n   - Explain specific code changes with clear reasoning\n   - Show before/after examples when suggesting changes\n   - Include compiler results to demonstrate the impact of optimizations\n   - Only suggest changes that meaningfully improve optimization potential\n\n## Optimization Guidelines\n- Avoid mutation of values that are memoized by the compiler\n- State updates should be structured to enable granular updates\n- Side effects should be isolated and dependencies clearly defined\n- The compiler automatically inserts memoization, so manually added useMemo/useCallback/React.memo can often be removed\n\n## Understanding Compiler Output\n- Successful optimization adds import { c as _c } from \"react/compiler-runtime\";\n- Successful optimization initializes a constant sized cache with const $ = _c(n), where n is the size of the cache as an integer\n- When suggesting changes, try to increase or decrease the number of cached expressions (visible in const $ = _c(n))\n  - Increase: more memoization coverage\n  - Decrease: if there are unnecessary dependencies, less dependencies mean less re-rendering\n`,\n      },\n    },\n  ],\n}));\n\nasync function main() {\n  const transport = new StdioServerTransport();\n  await server.connect(transport);\n  console.error('React Compiler MCP Server running on stdio');\n}\n\nmain().catch(error => {\n  console.error('Fatal error in main():', error);\n  process.exit(1);\n});\n"

    "content": "## Sprout 🌱\nReact Forget test framework that executes compiler fixtures.\n\nCurrently, Sprout runs each fixture with a known set of inputs and annotations. Sprout compares execution outputs (i.e. return values and console logs) of original source code and the corresponding Forget-transformed version.\nWe hope to add fuzzing capabilities to Sprout, synthesizing sets of program inputs based on type and/or effect annotations.\n\nSprout is now enabled for all fixtures! If Sprout cannot execute your fixture due to some technical limitations, add your fixture to [`SproutTodoFilter.ts`](./src/SproutTodoFilter.ts) with a comment explaining why.\n\n### Sprout CLI\nSprout is now run as a part of snap, except when in filter mode.\n\n### Adding fixtures to Sprout\n\n#### 1. Annotate fixtures.\nEach fixture test executed by Sprout needs to export const `FIXTURE_ENTRYPOINT` object with the following type signature.\n\n```js\ntype FixtureEntrypoint<T> = {\n  // function to be invoked\n  fn: ((...params: Array<T>) => any),\n  // params to pass to fn\n  // (if `fn` is a react component, this should be an array\n  // with exactly one element -- props)\n  params: Array<T>,\n}\n```\n\nExample:\n```js\n// test.js\nfunction MyComponent(props) {\n  return <div>{props.a + props.b}</div>;\n}\nexport const FIXTURE_ENTRYPOINT = {\n  fn: MyComponent,\n  params: [{a: \"hello \", b: \"world\"}],\n};\n```\n\n#### 2. Import / define helper functions.\n\n- Prefer importing helper functions for readability and simplicity.\n- Fixtures that require helper functions with specific types or mutability can define their own within the same fixture file.\n\n```js\n// test.js\nimport { addOne } from 'shared-runtime';\n\nfunction customHelper(val1, val2) {\n  // This directive is important, as helper functions don't\n  // always follow the rules of React.\n  \"use no forget\";\n  // ...\n}\n\n// ...\n```\n\n#### Notes\n- If your fixture needs to import from an external module, we currently only support importing from `react` (see Milestones todo list).\n\n- Any fixture can use React hooks, but they need to be first imported. We may later enforce that only `isComponent: true` fixtures can use React hooks.\n    ```ts\n    import {useState} from 'react';\n    ```\n\n- If your fixture wants to export multiple functions to Sprout to run, please split up the fixture into multiple files (e.g. `test-case-1`, `test-case-2`, etc).\n\n- Sprout currently runs each fixture in an iife to prevent variable collisions, but it does not run fixtures in isolation. Please do not mutate any external state in fixtures.\n\n- Sprout does not run fixtures listed in [`SproutTodoFilter.ts`](./src/SproutTodoFilter.ts), even in filter mode.\n\n### Milestones:\n- [✅] Render fixtures with React runtime / `testing-library/react`.\n- [✅] Make Sprout CLI -runnable and report results in process exit code.\n- [✅] Enable Sprout by default and run it in the Github Actions pipeline.\n- [🚧] Make all existing test fixtures Sprout compatible (see `SproutTodoFilter.ts`). This involves each fixture being annotated with `FIXTURE_ENTRYPOINT` and using shared functions and/or defining its own helpers.\n  - 77 done, ~410 to go\n- [✅] *(optional)* Store Sprout output as snapshot files. i.e. each fixture could have a `fixture.js`, `fixture.snap.md`, and `fixture.sprout.md`.\n- [✅] Add support for `fbt`.\n"

Some of\nthem are invalid or mis-capitalized or mixed up versions of real ones.\nEach column is a value which can be passed to that attribute.\nEvery cell has a box on the left and a box on the right.\nThe left box shows the property (or attribute) assigned by the latest stable release of React, and the\nright box shows the property (or attribute) assigned by the locally built version of React.\n\nRight now, we use a purple outline to call out cases where the assigned property\n(or attribute) has changed between React 15 and 16.\n\n---\n\n\nThis project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).\n\nYou can find the guide for how to do things in a CRA [here](https://github.com/facebook/create-react-app/blob/main/packages/cra-template/template/README.md).\n"

For now, this fixture is only a test harness.\n\nThere are also known bugs and inefficiencies in main so **don't use this fixture for demonstration purposes either yet**. Until they are fixed, this fixture is **not** indicative of React async rendering performance.\n\n## How do I run this fixture?\n\n### From npm version\n\n```\n# 1: Install fixture dependencies\ncd fixtures/unstable-async/time-slicing/\nyarn\n\n# 2: Run the app\nyarn start\n```\n\n### From React source code\n```shell\n# 1: Build react from source\ncd /path/to/react\nyarn\nyarn build react-dom/index,react/index,react-cache,scheduler --type=NODE\n\n# 2: Install fixture dependencies\ncd fixtures/unstable-async/time-slicing/\nyarn\n\n# 3: Copy React source code over\nyarn copy-source\n\n# 3: Run the app\nyarn start\n```\n"

    "content": "# Text Inputs\n\nThere are a couple of important concepts to be aware of when working on text\ninputs in React.\n\n## `defaultValue` vs `value`\n\nAn input's value is drawn from two properties: `defaultValue` and `value`.\n\nThe `defaultValue` property directly maps to the value _attribute_, for example:\n\n```javascript\nvar input = document.createElement('input')\ninput.defaultValue = 'hello'\n\nconsole.log(input.getAttribute('value')) // => \"hello\"\n```\n\nThe `value` property manipulates the _working value_ for the input. This property\nchanges whenever the user interacts with an input, or it is modified with JavaScript:\n\n```javascript\nvar input = document.createElement('input')\ninput.defaultValue = 'hello'\ninput.value = 'goodbye'\n\nconsole.log(input.getAttribute('value')) // => \"hello\"\nconsole.log(input.value) // => \"goodbye\"\n```\n\n## value detachment\n\nUntil `value` is manipulated by a user or JavaScript, manipulating `defaultValue`\nwill also modify the `value` property:\n\n```javascript\nvar input = document.createElement('input')\n// This will turn into 3\ninput.defaultValue = 3\n// This will turn into 5\ninput.defaultValue = 5\n// This will turn into 7\ninput.value = 7\n// This will do nothing\ninput.defaultValue = 1\n```\n\n**React detaches all inputs**. This prevents `value` from accidentally updating if\n`defaultValue` changes.\n\n## Form reset events\n\nReact does not support `form.reset()` for controlled inputs. This is a feature,\nnot a bug. `form.reset()` works by reverting an input's `value` _property_ to\nthat of the current `defaultValue`. Since React assigns the value `attribute`\nevery time a controlled input's value changes, controlled inputs will never\n\"revert\" back to their original display value.\n\n## Number inputs\n\nChrome (55) and Safari (10) attempt to \"correct\" the value of number inputs any\ntime the value property or attribute are changed. This leads to some edge documented\nhere:\n\nhttps://github.com/facebook/react/pull/7359#issuecomment-256499693\n"

If it's broken, ping [Dan](https://twitter.com/dan_abramov).\n\n### Running\n\nFirst, `npm run build` in React root repo folder.\n\nThen `npm install` and `npm start` in this folder.\n\nOpen `http://localhost:3000` in Chrome.\n\n### Features\n\n* Edit code that uses `ReactNoop` renderer\n* Visualize how relationships between fibers change over time\n* Current tree is displayed in green\n\n![fiber debugger](https://d17oy1vhnax1f7.cloudfront.net/items/3R2W1H2M3a0h3p1l133r/Screen%20Recording%202016-10-21%20at%2020.41.gif?v=e4323e51)\n\n\n"

    "content": "# Nested React Demo\n\nThis is a demo of how you can configure a build system to serve **two different versions of React** side by side in the same app. This is not optimal, and should only be used as a compromise to prevent your app from getting stuck on an old version of React.\n\n## You Probably Don't Need This\n\nNote that **this approach is meant to be an escape hatch, not the norm**.\n\nNormally, we encourage you to use a single version of React across your whole app. When you need to upgrade React, it is better to try to upgrade it all at once. We try to keep breaking changes between versions to the minimum, and often there are automatic scripts (\"codemods\") that can assist you with migration. You can always find the migration information for any release on [our blog](https://reactjs.org/blog/).\n\nUsing a single version of React removes a lot of complexity. It is also essential to ensure the best experience for your users who don't have to download the code twice. Always prefer using one React.\n\n## What Is This For?\n\nHowever, for some apps that have been in production for many years, upgrading all screens at once may be prohibitively difficult. For example, React components written in 2014 may still rely on [the unofficial legacy context API](https://reactjs.org/docs/legacy-context.html) (not to be confused with the modern one), and are not always maintained. \n\nTraditionally, this meant that if a legacy API is deprecated, you would be stuck on the old version of React forever. That prevents your whole app from receiving improvements and bugfixes. This repository demonstrates a hybrid approach. It shows how you can use a newer version of React for some parts of your app, while **lazy-loading an older version of React** for the parts that haven't been migrated yet.\n\nThis approach is inherently more complex, and should be used as a last resort when you can't upgrade.\n\n## Version Requirements\n\nThis demo uses two different versions of React: React 17 for \"modern\" components (in `src/modern`), and React 16.8 for \"legacy\" components (in `src/legacy`).\n\n**We still recommend upgrading your whole app to React 17 in one piece.** The React 17 release intentionally has minimal breaking changes so that it's easier to upgrade to. In particular, React 17 solves some problems with nesting related to event propagation that earlier versions of React did not handle well. We expect that this nesting demo may not be as useful today as during a future migration from React 17 to the future major versions where some of the long-deprecated APIs may be removed.\n\nHowever, if you're already stuck on an old version of React, you may found this approach useful today. If you remove a Hook call from `src/shared/Clock.js`, you can downgrade the legacy React all the way down to React 16.3. If you then remove Context API usage from `src/legacy/createLegacyRoot.js`, you can further downgrade the legacy React version, but keep in mind that the usage of third-party libraries included in this demo (React Router and React Redux) may need to be adjusted or removed.\n\n## Installation\n\nTo run this demo, open its folder in Terminal and execute:\n\n```sh\nnpm install\nnpm start\n```\n\nIf you want to test the production build, you can run instead:\n\n```\nnpm install\nnpm run build\nnpx serve -s build\n```\n\nThis sample app uses client-side routing and consists of two routes:\n\n- `/` renders a page which uses a newer version of React. (In the production build, you can verify that only one version of React is being loaded when this route is rendered.)\n- `/about` renders a page which uses an older version of React for a part of its tree. (In the production build, you can verify that both versions of React are loaded from different chunks.)\n\n**The purpose of this demo is to show some nuances of such setup:**\n\n- How to install two versions of React in a single app with npm side by side.\n- How to avoid the [\"invalid Hook call\" error](https://github.com/facebook/react/issues/13991) while nesting React trees.\n- How to pass context between different versions of React.\n- How to lazy-load the second React bundle so it's only loaded on the screens that use it.\n- How to do all of this without a special bundler configuration.\n\n## How It Works\n\nFile structure is extremely important in this demo. It has a direct effect on which code is going to use which version of React. This particular demo is using Create React App without ejecting, so **it doesn't rely on any bundler plugins or configuration**. The principle of this demo is portable to other setups.\n\n### Dependencies\n\nWe will use three different `package.json`s: one for non-React code at the root, and two in the respective `src/legacy` and `src/modern` folders that specify the React dependencies:\n\n- **`package.json`**: The root `package.json` is a place for build dependencies (such as `react-scripts`) and any React-agnostic libraries (for example, `lodash`, `immer`, or `redux`). We do **not** include React or any React-related libraries in this file.\n- **`src/legacy/package.json`**: This is where we declare the `react` and `react-dom`  dependencies for the \"legacy\" trees. In this demo, we're using React 16.8 (although, as noted above, we could downgrade it further below). This is **also** where we specify any third-party libraries that use React. For example, we include `react-router` and `react-redux` in this example. \n- **`src/modern/package.json`**: This is where we declare the `react` and `react-dom`  dependencies for the \"modern\" trees. In this demo, we're using React 17. Here, we also specify third-party dependencies that use React and are used from the modern part of our app. This is why we *also* have `react-router` and `react-redux` in this file. (Their versions don't strictly have to match their `legacy` counterparts, but features that rely on context may require workarounds if they differ.)\n\nThe `scripts` in the root `package.json` are set up so that when you run `npm install` in it, it also runs `npm install` in both `src/legacy` and `src/modern` folders.\n\n**Note:** This demo is set up to use a few third-party dependencies (React Router and Redux). These are not essential, and you can remove them from the demo. They are included so we can show how to make them work with this approach.\n\n### Folders\n\nThere are a few key folders in this example:\n\n- **`src`**: Root of the source tree. At this level (or below it, except for the special folders noted below), you can put any logic that's agnostic of React. For example, in this demo we have `src/index.js` which is the app's entry point, and `src/store.js` which exports a Redux store. These regular modules only execute once, and are **not** duplicated between the bundles.\n- **`src/legacy`**: This is where all the code using the older version of React should go. This includes React components and Hooks, and general product code that is **only** used by the legacy trees.\n- **`src/modern`**: This is where all the code using the newer version of React should go. This includes React components and Hooks, and general product code that is **only** used by the modern trees.\n- **`src/shared`**: You may have some components or Hooks that you wish to use from both modern and legacy subtrees. The build process is set up so that **everything inside `src/shared` gets copied by a file watcher** into both `src/legacy/shared` and `src/modern/shared` on every change. This lets you write a component or a Hook once, but reuse it in both places.\n \n### Lazy Loading\n\nLoading two Reacts on the same page is bad for the user experience, so you should strive to push this as far as possible from the critical path of your app. For example, if there is a dialog that is less commonly used, or a route that is rarely visited, those are better candidates for staying on an older version of React than parts of your homepage.\n\nTo encourage only loading the older React when necessary, this demo includes a helper that works similarly to `React.lazy`. For example, `src/modern/AboutPage.js`, simplified, looks like this:\n\n```js\nimport lazyLegacyRoot from './lazyLegacyRoot';\n\n// Lazy-load a component from the bundle using legacy React.\nconst Greeting = lazyLegacyRoot(() => import('../legacy/Greeting'));\n\nfunction AboutPage() {\n  return (\n    <>\n      <h3>This component is rendered by React ({React.version}).</h3>\n      <Greeting />\n    </>\n  );\n}\n```\n\nAs a result, only if the `AboutPage` (and as a result, `<Greeting />`) gets rendered, we will load the bundle containing the legacy React and the legacy `Greeting` component. Like with `React.lazy()`, we wrap it in `<Suspense>` to specify the loading indicator:\n\n```js\n<Suspense fallback={<Spinner />}>\n  <AboutPage />\n</Suspense>\n```\n\nIf the legacy component is only rendered conditionally, we won't load the second React until it's shown:\n\n```js\n<>\n  <button onClick={() => setShowGreeting(true)}>\n    Say hi\n  </button>\n  {showGreeting && (\n    <Suspense fallback={<Spinner />}>\n      <Greeting />\n    </Suspense>\n  )}\n</>\n```\n\n\nThe implementation of the `src/modern/lazyLegacyRoot.js` helper is included so you can tweak it and customize it to your needs. Remember to test lazy loading with the production builds because the bundler may not optimize it in development.\n\n### Context\n\nIf you have nested trees managed by different versions of React, the inner tree won't \"see\" the outer tree's Context.\n\nThis breaks third-party libraries like React Redux or React Router, as well as any of your own usage of Context (for example, for theming).\n\nTo solve this problem, we read all the Contexts we care about in the outer tree, pass them to the inner tree, and then wrap the inner tree in the corresponding Providers. You can see this in action in two files:\n\n* `src/modern/lazyLegacyRoot.js`: Look for `useContext` calls, and how their results are combined into a single object that is passed through. **You can read more Contexts there** if your app requires them.\n* `src/legacy/createLegacyRoot.js`: Look for the `Bridge` component which receives that object and wraps its children with the appropriate Context Providers. **You can wrap them with more Providers there** if your app requires them.\n\nNote that, generally saying, this approach is somewhat fragile, especially because some libraries may not expose their Contexts officially or consider their structure private. You may be able to expose private Contexts by using a tool like [patch-package](https://www.npmjs.com/package/patch-package), but remember to keep all the versions pinned because even a patch release of a third-party library may change the behavior.\n\n### Nesting Direction\n\nIn this demo, we use an older React inside an app managed by the newer React. However, we could rename the folders and apply the same approach in the other direction.\n\n### Event Propagation\n\nNote that before React 17, `event.stopPropagation()` in the inner React tree does not prevent the event propagation to the outer React tree. This may cause unexpected behavior when extracting a UI tree like a dialog to use a separate React. This is because prior to React 17, both Reacts would attach the event listener at the `document` level. React 17 fixes this by attaching handlers to the roots. We strongly recommend upgrading to React 17 before considering the nesting strategy for future upgrades.\n\n### Gotchas\n\nThis setup is unusual, so it has a few gotchas.\n\n* Don't add `package.json` to the `src/shared` folder. For example, if you want to use an npm React component inside `src/shared`, you should add it to both `src/modern/package.json` and `src/legacy/package.json` instead. You can use different versions of it but make sure your code works with both of them — and that it works with both Reacts!\n* Don't use React outside of the `src/modern`, `src/legacy`, or `src/shared`. Don't add React-related libraries outside of `src/modern/package.json` or `src/legacy/package.json`.\n* Remember that `src/shared` is where you write shared components, but the files you write there are automatically copied into `src/modern/shared` and `src/legacy/shared`, **from which you should import them**. Both of the target directories are in `.gitignore`. Importing directly from `src/shared` **will not work** because it is ambiguous what `react` refers to in that folder.\n* Keep in mind that any code in `src/shared` gets duplicated between the legacy and the modern bundles. Code that should not be duplicated needs to be anywhere else in `src` (but you can't use React there since the version is ambiguous).\n* You'll want to exclude `src/*/node_modules` from your linter's configuration, as this demo does in `.eslintignorerc`.\n\nThis setup is complicated, and we don't recommend it for most apps. However, we believe it is important to offer it as an option for apps that would otherwise get left behind. There might be ways to simplify it with a layer of tooling, but this example is intentionally showing the low-level mechanism that other tools may build on.\n"

Once you `eject`, you can't go back!**\n\nIf you aren't satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.\n\nInstead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.\n\nYou don't have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.\n\n## Learn More\n\nYou can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).\n\nTo learn React, check out the [React documentation](https://reactjs.org/).\n\n### Code Splitting\n\nThis section has moved here: [https://facebook.github.io/create-react-app/docs/code-splitting](https://facebook.github.io/create-react-app/docs/code-splitting)\n\n### Analyzing the Bundle Size\n\nThis section has moved here: [https://facebook.github.io/create-react-app/docs/analyzing-the-bundle-size](https://facebook.github.io/create-react-app/docs/analyzing-the-bundle-size)\n\n### Making a Progressive Web App\n\nThis section has moved here: [https://facebook.github.io/create-react-app/docs/making-a-progressive-web-app](https://facebook.github.io/create-react-app/docs/making-a-progressive-web-app)\n\n### Advanced Configuration\n\nThis section has moved here: [https://facebook.github.io/create-react-app/docs/advanced-configuration](https://facebook.github.io/create-react-app/docs/advanced-configuration)\n\n### Deployment\n\nThis section has moved here: [https://facebook.github.io/create-react-app/docs/deployment](https://facebook.github.io/create-react-app/docs/deployment)\n\n### `yarn build` fails to minify\n\nThis section has moved here: [https://facebook.github.io/create-react-app/docs/troubleshooting#npm-run-build-fails-to-minify](https://facebook.github.io/create-react-app/docs/troubleshooting#npm-run-build-fails-to-minify)\n"

Feel free to contribute to automate them.)\n\nRun them when you make changes to how we package React and ReactDOM.\n\n## How to Run\n\nFirst, build React and the fixtures:\n\n```\ncd react\nnpm run build\nnode fixtures/packaging/build-all.js\n```\n\nThen run a local server, e.g.\n\n```\nnpx pushstate-server .\n```\n\nand open the following URL in your browser: [http://localhost:9000/fixtures/packaging/index.html](http://localhost:9000/fixtures/packaging/index.html)\n\nYou should see two things:\n\n* A number of iframes (corresponding to various builds), with \"Hello World\" rendered in each iframe.\n* No errors in the console.\n"

    "content": "# `dom-event-testing-library`\n\nA library for unit testing events via high-level interactions, e.g., `pointerdown`,\nthat produce realistic and complete DOM event sequences.\n\nThere are number of challenges involved in unit testing modules that work with\nDOM events.\n\n1. Gesture recognizers may need to support environments with and without support for\n   the `PointerEvent` API.\n2. Gesture recognizers may need to support various user interaction modes including\n   mouse, touch, and pen use.\n3. Gesture recognizers must account for the actual event sequences browsers produce\n   (e.g., emulated touch and mouse events.)\n4. Gesture recognizers must work with \"virtual\" events produced by tools like\n   screen-readers.\n\nWriting unit tests to cover all these scenarios is tedious and error prone. This\nevent testing library is designed to solve these issues by allowing developers to\nmore easily dispatch events in unit tests, and to more reliably test pointer\ninteractions using a high-level API based on `PointerEvent`. Here's a basic example:\n\n```js\nimport {\n  describeWithPointerEvent,\n  testWithPointerType,\n  createEventTarget,\n  setPointerEvent,\n  resetActivePointers\n} from 'dom-event-testing-library';\n\ndescribeWithPointerEvent('useTap', hasPointerEvent => {\n  beforeEach(() => {\n    // basic PointerEvent mock\n    setPointerEvent(hasPointerEvent);\n  });\n\n  afterEach(() => {\n    // clear active pointers between test runs\n    resetActivePointers();\n  });\n\n  // test all the pointer types supported by the environment\n  testWithPointerType('pointer down', pointerType => {\n    const ref = createRef(null);\n    const onTapStart = jest.fn();\n    render(() => {\n      useTap(ref, { onTapStart });\n      return <div ref={ref} />\n    });\n\n    // create an event target\n    const target = createEventTarget(ref.current);\n    // dispatch high-level pointer event\n    target.pointerdown({ pointerType });\n\n    expect(onTapStart).toBeCalled();\n  });\n});\n```\n\nThis tests the interaction in multiple scenarios. In each case, a realistic DOM\nevent sequence–with complete mock events–is produced. When running in a mock\nenvironment without the `PointerEvent` API, the test runs for both `mouse` and\n`touch` pointer types. When `touch` is the pointer type it produces emulated mouse\nevents. When running in a mock environment with the `PointerEvent` API, the test\nruns for `mouse`, `touch`, and `pen` pointer types.\n\nIt's important to cover all these scenarios because it's very easy to introduce\nbugs – e.g., double calling of callbacks – if not accounting for emulated mouse\nevents, differences in target capturing between `touch` and `mouse` pointers, and\nthe different semantics of `button` across event APIs.\n\nDefault values are provided for the expected native events properties. They can\nalso be customized as needed in a test.\n\n```js\ntarget.pointerdown({\n  button: 0,\n  buttons: 1,\n  pageX: 10,\n  pageY: 10,\n  pointerType,\n  // NOTE: use x,y instead of clientX,clientY\n  x: 10,\n  y: 10\n});\n```\n\nTests that dispatch multiple pointer events will dispatch multi-touch native events\non the target.\n\n```js\n// first pointer is active\ntarget.pointerdown({pointerId: 1, pointerType});\n// second pointer is active\ntarget.pointerdown({pointerId: 2, pointerType});\n```\n"

    "content": "# `eslint-plugin-react-hooks`\n\nThe official ESLint plugin for [React](https://react.dev) which enforces the [Rules of React](https://react.dev/reference/eslint-plugin-react-hooks) and other best practices.\n\n## Installation\n\nAssuming you already have ESLint installed, run:\n\n```sh\n# npm\nnpm install eslint-plugin-react-hooks --save-dev\n\n# yarn\nyarn add eslint-plugin-react-hooks --dev\n```\n\n### Flat Config (eslint.config.js|ts)\n\nAdd the `recommended` config for all recommended rules:\n\n```js\n// eslint.config.js\nimport reactHooks from 'eslint-plugin-react-hooks';\nimport { defineConfig } from 'eslint/config';\n\nexport default defineConfig([\n  reactHooks.configs.flat.recommended,\n]);\n```\n\nIf you want to try bleeding edge experimental compiler rules, use `recommended-latest`.\n\n```js\n// eslint.config.js\nimport reactHooks from 'eslint-plugin-react-hooks';\nimport { defineConfig } from 'eslint/config';\n\nexport default defineConfig([\n  reactHooks.configs.flat['recommended-latest'],\n]);\n```\n\n### Legacy Config (.eslintrc)\n\nIf you are still using ESLint below 9.0.0, the `recommended` preset can also be used to enable all recommended rules.\n\n```js\n{\n  \"extends\": [\"plugin:react-hooks/recommended\"],\n  // ...\n}\n\n```\n\n### Custom Configuration\n\nIf you want more fine-grained configuration, you can instead choose to enable specific rules. However, we strongly encourage using the recommended presets — see above — so that you will automatically receive new recommended rules as we add them in future versions of the plugin.\n\n#### Flat Config (eslint.config.js|ts)\n\n```js\nimport reactHooks from 'eslint-plugin-react-hooks';\n\nexport default [\n  {\n    files: ['**/*.{js,jsx}'],\n    plugins: { 'react-hooks': reactHooks },\n    // ...\n    rules: {\n      // Core hooks rules\n      'react-hooks/rules-of-hooks': 'error',\n      'react-hooks/exhaustive-deps': 'warn',\n\n      // React Compiler rules\n      'react-hooks/config': 'error',\n      'react-hooks/error-boundaries': 'error',\n      'react-hooks/component-hook-factories': 'error',\n      'react-hooks/gating': 'error',\n      'react-hooks/globals': 'error',\n      'react-hooks/immutability': 'error',\n      'react-hooks/preserve-manual-memoization': 'error',\n      'react-hooks/purity': 'error',\n      'react-hooks/refs': 'error',\n      'react-hooks/set-state-in-effect': 'error',\n      'react-hooks/set-state-in-render': 'error',\n      'react-hooks/static-components': 'error',\n      'react-hooks/unsupported-syntax': 'warn',\n      'react-hooks/use-memo': 'error',\n      'react-hooks/incompatible-library': 'warn',\n    }\n  },\n];\n```\n\n#### Legacy Config (.eslintrc)\n```js\n{\n  \"plugins\": [\n    // ...\n    \"react-hooks\"\n  ],\n  \"rules\": {\n    // ...\n    // Core hooks rules\n    \"react-hooks/rules-of-hooks\": \"error\",\n    \"react-hooks/exhaustive-deps\": \"warn\",\n\n    // React Compiler rules\n    \"react-hooks/config\": \"error\",\n    \"react-hooks/error-boundaries\": \"error\",\n    \"react-hooks/component-hook-factories\": \"error\",\n    \"react-hooks/gating\": \"error\",\n    \"react-hooks/globals\": \"error\",\n    \"react-hooks/immutability\": \"error\",\n    \"react-hooks/preserve-manual-memoization\": \"error\",\n    \"react-hooks/purity\": \"error\",\n    \"react-hooks/refs\": \"error\",\n    \"react-hooks/set-state-in-effect\": \"error\",\n    \"react-hooks/set-state-in-render\": \"error\",\n    \"react-hooks/static-components\": \"error\",\n    \"react-hooks/unsupported-syntax\": \"warn\",\n    \"react-hooks/use-memo\": \"error\",\n    \"react-hooks/incompatible-library\": \"warn\"\n  }\n}\n```\n\n## Advanced Configuration\n\n`exhaustive-deps` can be configured to validate dependencies of custom Hooks with the `additionalHooks` option.\nThis option accepts a regex to match the names of custom Hooks that have dependencies.\n\n```js\n{\n  rules: {\n    // ...\n    \"react-hooks/exhaustive-deps\": [\"warn\", {\n      additionalHooks: \"(useMyCustomHook|useMyOtherCustomHook)\"\n    }]\n  }\n}\n```\n\nWe suggest to use this option **very sparingly, if at all**. Generally saying, we recommend most custom Hooks to not use the dependencies argument, and instead provide a higher-level API that is more focused around a specific use case.\n\n## Valid and Invalid Examples\n\nPlease refer to the [Rules of Hooks](https://react.dev/reference/rules/rules-of-hooks) documentation to learn more about this rule.\n\n## License\n\nMIT\n"

main pieces](https://github.com/facebook/react/blob/main/packages/react-devtools/OVERVIEW.md#overview):\n* The *frontend* users interact with (the Components tree, the Profiler, etc.).\n* The *backend* which runs in the same context as React itself. (In the web page with React DOM or shipped on the device with the React Native runtime.)\n\nThis release updates the [**protocol** that DevTools uses](https://github.com/facebook/react/blob/main/packages/react-devtools/OVERVIEW.md#serializing-the-tree) to communicate between the \"frontend\" and \"backend\" components.\n\nBecause React Native embeds a copy of the React DevTools \"backend\" ([`react-devtools-core/backend`](https://www.npmjs.com/package/react-devtools-core)), the \"frontend\" (UI) needs to match. This means you may be prompted to upgrade (or downgrade) your React DevTools based on which version of React Native your app uses.\n\n#### Features\n* Support multiple DevTools instances per page ([@bvaughn](https://github.com/bvaughn) in [#22949](https://github.com/facebook/react/pull/22949))\n* Advocate for StrictMode usage within Components tree ([@bvaughn](https://github.com/bvaughn) in

([@eps1lon](https://github.com/eps1lon) in [#22599](https://github.com/facebook/react/pull/22599))\n\n#### Bugfix\n* DevTools should inject itself for XHTML pages too (not just HTML) ([@bvaughn](https://github.com/bvaughn) in [#22932](https://github.com/facebook/react/pull/22932))\n* Don't restore profiling data if we're profling ([@eps1lon](https://github.com/eps1lon) in

are when rendering. It didn’t provide an overview of *what React is doing* (the actual cooperative scheduling bits). The new profiler does. It shows when components schedule state updates and when React works on them. It also shows how React categorizes and prioritizing what it works on.\n\nHere’s a profile for a simple app that uses only the legacy (synchronous) `ReactDOM.render` API. The profiler shows that all of the work scheduled and rendered by this app is done at *synchronous* priority:\n\nhttps://user-images.githubusercontent.com/29597/129042321-56985f5a-264e-4f3a-a8b7-9371d75c690f.mp4\n\nHere’s a more interesting profile for an app that’s rendered at _default_ priority using the new [`createRoot` API](https://github.com/reactwg/react-18/discussions/5), then updates _synchronously_ in response to an “input” event to manage a [\"controlled component\"](https://reactjs.org/docs/forms.html#controlled-components):\n\nhttps://user-images.githubusercontent.com/29597/129074959-50912a63-0215-4be5-b51b-1e0004fcd2a1.mp4\n\nHere’s part of a profile showing an idle app (no JavaScript running). In this case, React does some pre-rendering work for components that are “offscreen” (not currently displayed).\n\nhttps://user-images.githubusercontent.com/29597/128971757-612f232f-c64f-4447-a766-66a0516e8f49.mp4\n\nNote that “offscreen” refers to a new API and set of features that we haven’t talked about much yet except for [some passing references](https://github.com/reactwg/react-18/discussions/18#discussioncomment-795661). We’ll talk more about it in future posts.\n\n###### What are “transitions” and how do they work?\nWe recently shared an update about the new [`startTransition` API](https://github.com/reactwg/react-18/discussions/41). This API helps apps feel responsive even when there are large updates by splitting the work into (1) a quick update to show that the app has received some input and (2) a slower update (the “transition”) that actually does any heavy lifting needed as a result of the input.\n\nHere is an example profile that uses the transition API. First React renders a small update that shows the user some visual feedback (like updating a controlled component or showing an inline loading indicator). Then it renders a larger update that, in this case, computes some expensive value.\n\nhttps://user-images.githubusercontent.com/29597/129079176-0995c8c0-e95a-4f44-8d55-891a7efa35c0.mp4\n\n###### How does Suspense impact rendering performance?\n\nYou may have heard mention of “suspense” in past talks or seen it referenced [in our docs](https://reactjs.org/docs/react-api.html#suspense). Although full support for data fetching via Suspense is [expected to be released sometime after React 18.0](https://github.com/reactwg/react-18/discussions/47#discussioncomment-847004), you can use Suspense today for things like lazy-loading React components. The new profiler shows when components suspend during render and how that impacts overall rendering performance.\n\nHere’s an example profile that suspends during the initial render to lazy-load a component using [`React.lazy`](https://reactjs.org/docs/code-splitting.html#reactlazy). While this component is loading, React shows a “fallback“ (placeholder UI). Once the component finishes loading, React retries the render and commits the final UI.\n\nhttps://user-images.githubusercontent.com/29597/129054366-2700e7e8-0172-4f61-9453-475acd740456.mp4\n\nWe plan to expand support for Suspense in the coming weeks to more explicitly show when suspense fallbacks are rendered and which subsequent renders are related to an initial update that suspended.\n\n###### What else might cause a render to get delayed?\n\nSuspense can cause a render to get delayed as React waits for data to load, but React can also get stuck waiting on a lot of JavaScript to run.\n\nReact profiling tools have previously focused on only reporting what React (or React components) are doing, but any JavaScript the browser runs affects performance. The new profiler shows non-React JavaScript as well, making it easy to see when it delays React from rendering.\n\nhttps://user-images.githubusercontent.com/29597/128971952-7c4e7e11-f4fb-497e-b643-4d9b3994b590.mp4\n\n###### What can you do to improve performance?\n\nUntil now, DevTools (and the Profiler) has provided information without commentary. The new profiler takes a more active approach– highlighting where we think performance can be improved and providing suggestions.\n\nFor example, suspending during an update is generally a bad user experience because it causes previously shown components to be unmounted (hidden) so the fallback can be shown while data loads. This can be avoided using the new [Transition API](https://github.com/reactwg/react-18/discussions/41). If you forget to add a transition to an update that suspends, the new profiler will warn you about this:\n\nhttps://user-images.githubusercontent.com/29597/128972228-3b23f01a-8017-43ad-b371-975ffed26c06.mp4\n\nThe new profiler also warns about scheduling a long, synchronous React update inside of event handler.\n\nhttps://user-images.githubusercontent.com/29597/128972000-d7477ba3-b779-46f2-b141-aaa712e9d6d2.mp4\n\nAnother thing the new profiler will warn about is long-running renders scheduled from layout effects (`useLayoutEffect` or `componentDidMount`/`componentDidUpdate`). These updates (called “nested updates”) are sometimes necessary to adjust layout before the browser paints, but they should be *fast*. Slow nested updates make the browser feel unresponsive.\n\nhttps://user-images.githubusercontent.com/29597/128972017-3ed0e682-751c-46fb-a6c5-271f255c8087.mp4\n\n---\n\n### 4.14.0\nJuly 17, 2021\n####

That overhead has been effectively eliminated in version 4.\n\n[Learn more](https://github.com/facebook/react/blob/main/packages/react-devtools/OVERVIEW.md) about the performance optimizations that made this possible.\n\n#### Component stacks\n\nReact component authors have often requested a way to log warnings that include the React [\"component stack\"](https://reactjs.org/docs/error-boundaries.html#component-stack-traces). DevTools now provides an option to automatically append this information to warnings (`console.warn`) and errors (`console.error`).\n\n![Example console warning with component stack added](https://user-images.githubusercontent.com/29597/62228120-eec3da80-b371-11e9-81bb-018c1e577389.png)\n\nIt can be disabled in the general settings panel:\n\n![Settings panel showing \"component stacks\" option](https://user-images.githubusercontent.com/29597/62227882-8f65ca80-b371-11e9-8a4e-5d27011ad1aa.png)\n\n---\n\n### Components tree changes\n\n#### Component filters\n\nLarge component trees can sometimes be hard to navigate. DevTools now provides a way to filter components so that you can hide ones you're not interested in seeing.\n\n![Component filter demo video](https://user-images.githubusercontent.com/29597/62229209-0bf9a880-b374-11e9-8f84-cebd6c1a016b.gif)\n\nHost nodes (e.g. HTML `<div>`, React Native `View`) are now hidden by default, but you can see them by disabling that filter.\n\nFilter preferences are remembered between sessions.\n\n#### No more inline props\n\nComponents in the tree no longer show inline props. This was done to [make DevTools faster](https://github.com/facebook/react/blob/main/packages/react-devtools/OVERVIEW.md) and to make it easier to browse larger component trees.\n\nYou can view a component's props, state, and hooks by selecting it:\n\n![Inspecting props](https://user-images.githubusercontent.com/29597/62303001-37da6400-b430-11e9-87fd-10a94df88efa.png)\n\n#### \"Rendered by\" list\n\nIn React, an element's \"owner\" refers to the thing that rendered it. Sometimes an element's parent is also its owner, but usually they're different. This distinction is important because props come from owners.\n\n![Example code](https://user-images.githubusercontent.com/29597/62229551-bbcf1600-b374-11e9-8411-8ff411f4f847.png)\n\nWhen you are debugging an unexpected prop value, you can save time if you skip over the parents.\n\nDevTools v4 adds a new \"rendered by\" list in the right hand pane that allows you to quickly step through the list of owners to speed up your debugging.\n\n![Example video showing the \"rendered by\" list](https://user-images.githubusercontent.com/29597/62229747-4152c600-b375-11e9-9930-3f6b3b92be7a.gif)\n\n#### Owners tree\n\nThe inverse of the \"rendered by\" list is called the \"owners tree\". It is the list of things rendered by a particular component- (the things it \"owns\"). This view is kind of like looking at the source of the component's render method, and can be a helpful way to explore large, unfamiliar React applications.\n\nDouble click a component to view the owners tree and click the \"x\" button to return to the full component tree:\n\n![Demo showing \"owners tree\" feature](https://user-images.githubusercontent.com/29597/62229452-84f90000-b374-11e9-818a-61eec6be0bb4.gif)\n\n#### No more horizontal scrolling\n\nDeeply nested components used to require both vertical and horizontal scrolling to see, making it easy to \"get lost\" within large component trees. DevTools now dynamically adjusts nesting indentation to eliminate horizontal scrolling.\n\n![Video demonstration dynamic indentation to eliminate horizontal scrolling](https://user-images.githubusercontent.com/29597/62246661-f8ad0400-b398-11e9-885f-284f150a6d76.gif)\n\n#### Improved hooks support\n\nHooks now have the same level of support as props and state: values can be edited, arrays and objects can be drilled into, etc.\n\n![Video demonstrating hooks support](https://user-images.githubusercontent.com/29597/62230532-d86c4d80-b376-11e9-8629-1b2129b210d6.gif)\n\n#### Improved search UX\n\nLegacy DevTools search filtered the components tree to show matching nodes as roots. This made the overall structure of the application harder to reason about, because it displayed ancestors as siblings.\n\nSearch results are now shown inline similar to the browser's find-in-page search.\n\n![Video demonstrating the search UX](https://user-images.githubusercontent.com/29597/62230923-c63edf00-b377-11e9-9f95-aa62ddc8f62c.gif)\n\n#### Higher order components\n\n[Higher order components](https://reactjs.org/docs/higher-order-components.html) (or HOCs) often provide a [custom `displayName`](https://reactjs.org/docs/higher-order-components.html#convention-wrap-the-display-name-for-easy-debugging) following a convention of `withHOC(InnerComponentName)` in order to make it easier to identify components in React warnings and in DevTools.\n\nThe new Components tree formats these HOC names (along with several built-in utilities like `React.memo` and `React.forwardRef`) as a special badge to the right of the decorated component name.\n\n![Screenshot showing HOC badges](https://user-images.githubusercontent.com/29597/62302774-c4385700-b42f-11e9-9ef4-49c5f18d6276.png)\n\nComponents decorated with multiple HOCs show the topmost badge and a count. Selecting the component shows all of the HOCs badges in the properties panel.\n\n![Screenshot showing a component with multiple HOC badges](https://user-images.githubusercontent.com/29597/62303729-7fadbb00-b431-11e9-8685-45f5ab52b30b.png)\n\n#### Restoring selection between reloads\n\nDevTools now attempts to restore the previously selected element when you reload the page.\n\n![Video demonstrating selection persistence](https://user-images.githubusercontent.com/810438/63130054-2c02ac00-bfb1-11e9-92fa-382e9e433638.gif)\n\n#### Suspense toggle\n\nReact's experimental [Suspense API](https://reactjs.org/docs/react-api.html#suspense) lets components \"wait\" for something before rendering. `<Suspense>` components can be used to specify loading states when components deeper in the tree are waiting to render.\n\nDevTools lets you test these loading states with a new toggle:\n\n![Video demonstrating suspense toggle UI](https://user-images.githubusercontent.com/29597/62231446-e15e1e80-b378-11e9-92d4-086751dc65fc.gif)\n\n---\n\n### Profiler changes\n\n#### Reload and profile\n\nThe profiler is a powerful tool for performance tuning React components. Legacy DevTools supported profiling, but only after it detected a profiling-capable version of React. Because of this there was no way to profile the initial _mount_ (one of the most performance sensitive parts) of an application.\n\nThis feature is now supported with a \"reload and profile\" action:\n\n![Video demonstrating the reload-and-profile feature](https://user-images.githubusercontent.com/29597/62233455-7a8f3400-b37d-11e9-9563-ec334bfb2572.gif)\n\n#### Import/export\n\nProfiler data can now be exported and shared with other developers to enable easier collaboration.\n\n![Video demonstrating exporting and importing profiler data](https://user-images.githubusercontent.com/29597/62233911-6566d500-b37e-11e9-9052-692378c92538.gif)\n\nExports include all commits, timings, interactions, etc.\n\n#### \"Why did this render?\"\n\n\"Why did this render?\" is a common question when profiling. The profiler now helps answer this question by recording which props and state change between renders.\n\n![Video demonstrating profiler \"why did this render?\" feature](https://user-images.githubusercontent.com/29597/62234698-0f932c80-b380-11e9-8cf3-a5183af0c388.gif)\n\nBecause this feature adds a small amount of overhead, it can be disabled in the profiler settings panel.\n\n#### Component renders list\n\nThe profiler now displays a list of each time the selected component rendered during a profiling session, along with the duration of each render. This list can be used to quickly jump between commits when analyzing the performance of a specific component.\n\n![Video demonstrating profiler's component renders list](https://user-images.githubusercontent.com/29597/62234547-bcb97500-b37f-11e9-9615-54fba8b574b9.gif)\n"

    "content": "\nInterested in contributing to React DevTools, but not sure where to start? This is the place!\n\n# Install project dependencies\nTo get started, check out the React repo:\n```sh\ngit clone git@github.com:facebook/react.git\n```\nNext install dependencies:\n```sh\ncd <react-repo>\nyarn install\n```\n\n# Build React and React DOM\nNext, check out (or build) the local version of React that DevTools uses:\n\n### Option 1 (fastest): Checkout pre-built React\nTo check out the latest version of React (built by CI from the `main` branch) run:\n```sh\ncd <react-repo>\n\ncd scripts/release\nyarn install\n\n./download-experimental-build.js --commit=main\n```\n\n### Option 2: Build from source\nIf your DevTools change includes local changes to React (or if CI is down for some reason) you can also build from source:\n```sh\ncd <react-repo>\nyarn build-for-devtools\n```\n\n# Testing your changes\n\n### Option 1 (fastest): Using the test shell\nMost changes can be tested using the DevTools test app. To run this, you'll need two terminals:\n\nFirst, run DevTools in DEV mode:\n```sh\ncd <react-repo>\ncd packages/react-devtools-inline\nyarn start\n```\nNext, run the test shell:\n```sh\ncd <react-repo>\ncd packages/react-devtools-shell\nyarn start\n```\nNow any changes you make to DevTools will automatically reload in the test app at http://localhost:8080\n\n### Option 2: Using the extension\nSome changes requiring testing in the browser extension (e.g. like \"named hooks\"). To do this, run the following script:\n```sh\ncd <react-repo>\ncd packages/react-devtools-extensions\nyarn build:chrome:local && yarn test:chrome\n```\nThis will launch a standalone version of Chrome with the locally built React DevTools pre-installed. If you are testing a specific URL, you can make your testing even faster by passing the `--url` argument to the test script:\n```sh\nyarn build:chrome && yarn test:chrome --url=<url-to-test>\n```\n\n# Unit tests\nCore DevTools functionality is typically unit tested (see [here](https://github.com/facebook/react/tree/main/packages/react-devtools-shared/src/__tests__)). To run tests, you'll first need to build or download React and React DOM ([as explained above](#build-react-and-react-dom)) and then use the following NPM script:\n```sh\nyarn test-build-devtools\n```\nYou can connect tests to a debugger as well if you'd like by running:\n```sh\nyarn debug-test-build-devtools\n```\n\n# Finding the right first issue\nThe React team maintains [this list of \"good first issues\"](https://github.com/facebook/react/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc+label%3A%22Component%3A+Developer+Tools%22+label%3A%22good+first+issue%22) for anyone interested in contributing to DevTools. If you see one that interests you, leave a comment!\n\nIf you have ideas or suggestions of your own, you can also put together a PR demonstrating them. We suggest filing an issue before making any substantial changes though, to ensure that the idea is something the team feels comfortable landing.\n"

    "path": "packages/react-devtools/OVERVIEW.md",
    "content": "# Overview\n\nThe React DevTools extension consists of multiple pieces:\n* The **frontend** portion is the extension you see (the Components tree, the Profiler, etc.).\n* The **backend** portion is invisible. It runs in the same context as React itself. When React commits changes to e.g. the DOM, the backend is responsible for notifying the frontend by sending a message through the **bridge** (an abstraction around e.g. `postMessage`).\n\nOne of the largest performance bottlenecks of the old React DevTools was the amount of bridge traffic. Each time React commits an update, the backend sends every fiber that changed across the bridge, resulting in a lot of (JSON) serialization. The primary goal for the DevTools rewrite was to reduce this traffic. Instead of sending everything across the bridge, **the backend should only send the minimum amount required to render the Components tree**. The frontend can request more information (e.g. an element's props) on-demand, only as needed.\n\nThe old DevTools also rendered the entire application tree in the form of a large DOM structure of nested nodes. A secondary goal of the rewrite was to avoid rendering unnecessary nodes by using a windowing library (specifically [react-window](https://github.com/bvaughn/react-window)).\n\n## Components panel\n\n### Serializing the tree\n\nEvery React commit that changes the tree in a way DevTools cares about results in an \"_operations_\" message being sent across the bridge. These messages are lightweight patches that describe the changes that were made. (We don't resend the full tree structure like in legacy DevTools.)\n\nThe payload for each message is a typed array. The first two entries are numbers that identify which renderer and root the update belongs to (for multi-root support). Then the strings are encoded in a [string table](#string-table). The rest of the array depends on the operations being made to the tree.\n\nNo updates are required for most commits because we only send the following bits of information: element type, id, parent id, owner id, name, and key. Additional information (e.g. props, state) requires a separate [\"_inspectElement_\" message](#inspecting-an-element).\n\n#### String table\n\nThe string table is encoded right after the first two numbers.\n\nIt consists of:\n\n1. the total length of the next items that belong to the string table\n2. for each string in a table:\n    * encoded size\n    * a list of its UTF encoded codepoints\n\nFor example, for `Foo` and `Bar` we would see:\n\n```\n[\n  8,   // string table length\n  3,   // encoded display name size\n  70,  // \"F\"\n  111, // \"o\"\n  111, // \"o\"\n  3,   // encoded display name size\n  66,  // \"B\"\n  97,  // \"a\"\n  114, // \"r\"\n]\n```\n\nLater operations will reference strings by a one-based index. For example, `1` would mean `\"Foo\"`, and `2` would mean `\"Bar\"`. The `0` string id always represents `null` and isn't explicitly encoded in the table.\n\n#### Adding a root node\n\nAdding a root to the tree requires sending 5 numbers:\n\n1. add operation constant (`1`)\n1. fiber id\n1. element type constant (`11 === ElementTypeRoot`)\n1. root has `StrictMode` enabled\n1. supports profiling flag\n1. supports `StrictMode` flag\n1. owner metadata flag\n\nFor example, adding a root fiber with an id of 1:\n```js\n[\n  1, // add operation\n  1, // fiber id\n  11, // ElementTypeRoot\n  1, // this root is StrictMode enabled\n  1, // this root's renderer supports profiling\n  1, // this root's renderer supports StrictMode\n  1, // this root has owner metadata\n]\n```\n\n#### Adding a leaf node\n\nAdding a leaf node to the tree requires sending 7 numbers:\n\n1. add operation constant (`1`)\n1. fiber id\n1. element type constant (e.g. `1 === ElementTypeClass`)\n1. parent fiber id\n1. owner fiber id\n1. string table id for `displayName`\n1. string table id for `key`\n\nFor example, adding a function component `<Foo>` with an id 2:\n```js\n[\n  1,   // add operation\n  2,   // fiber id\n  1,   // ElementTypeClass\n  1,   // parent id\n  0,   // owner id\n  1,   // id of \"Foo\" displayName in the string table\n  0,   // id of null key in the string table (always zero for null)\n]\n```\n\n#### Removing a node\n\nRemoving a fiber from the tree (a root or a leaf) requires sending:\n\n1. remove operation constant (`2`)\n1. how many items were removed\n1. number of children\n   * (followed by a children-first list of removed fiber ids)\n\nFor example, removing fibers with ids of 35 and 21:\n```js\n[\n  2, // remove operation\n  2, // number of removed fibers\n  35, // first removed id\n  21, // second removed id\n]\n```\n\n#### Re-ordering children\n\n1. re-order children constant (`3`)\n1. fiber id\n1. number of children\n   * (followed by an ordered list of child fiber ids)\n\nFor example:\n```js\n[\n  3,  // re-order operation\n  15, // fiber id\n  2,  // number of children\n  35, // first child id\n  21, // second child id\n]\n```\n\n#### Updating tree base duration\n\nWhile profiling is in progress, we send an extra operation any time a fiber is added or updated in a way that affects its tree base duration. This information is needed by the Profiler UI in order to render the \"snapshot\" and \"ranked\" chart views.\n\n1. tree base duration constant (`4`)\n1. fiber id\n1. tree base duration\n\nFor example, updating the base duration for a fiber with an id of 1:\n```js\n[\n  4,  // update tree base duration operation\n  4,  // tree base duration operation\n  1,  // fiber id\n  32, // new tree base duration value\n]\n```\n\n#### Updating errors and warnings on a Fiber\n\nWe record calls to `console.warn` and `console.error` in the backend.\nPeriodically we notify the frontend that the number of recorded calls got updated.\nWe only send the serialized messages as part of the `inspectElement` event.\n\n\n```js\n[\n  5, // update error/warning counts operation\n  4, // fiber id\n  0, // number of calls to console.error from that fiber\n  3, // number of calls to console.warn from that fiber\n]\n```\n\n#### Removing a root\n\nA special case of unmounting an entire root (including its descendants). This specialized message replaces what would otherwise be a series of remove-node operations. It is currently only used in one case: updating component filters. The primary motivation for this is actually to preserve fiber ids for components that are re-added to the tree after the updated filters have been applied. This preserves mappings between the Fiber (id) and things like error and warning logs.\n\n```js\n[\n  6, // remove root operation\n]\n```\n\nThis operation has no additional payload because renderer and root ids are already sent at the beginning of every operations payload.\n\n#### Setting the mode for a subtree\n\nThis message specifies that a subtree operates under a specific mode (e.g. `StrictMode`).\n\n```js\n[\n  7,   // set subtree mode\n  1,   // subtree root fiber id\n  0b01 // mode bitmask\n]\n```\n\nModes are constant meaning that the modes a subtree mounts with will never change.\n\n## Reconstructing the tree\n\nThe frontend stores its information about the tree in a map of id to objects with the following keys:\n\n* id: `number`\n* parentID: `number`\n* children: `Array<number>`\n* type: `number` (constant)\n* displayName: `string | null`\n* key: `number | string | null`\n* ownerID: `number`\n* depth: `number` <sup>1</sup>\n* weight: `number` <sup>2</sup>\n\n<sup>1</sup> The `depth` value determines how much padding/indentation to use for the element when rendering it in the Components panel. (This preserves the appearance of a nested tree, even though the view is a flat list.)\n\n<sup>2</sup> The `weight` of an element is the number of elements (including itself) below it in the tree. We cache this property so that we can quickly determine the total number of Components as well as find the Nth element within that set. (This enables us to use windowing.) This value needs to be adjusted each time elements are added or removed from the tree, but we amortize this over time to avoid any big performance hits when rendering the tree.\n\n#### Finding the element at index N\n\nThe tree data structure lets us impose an order on elements and \"quickly\" find the Nth one using the `weight` attribute.\n\nFirst we find which root contains the index:\n```js\nlet rootID;\nlet root;\nlet rootWeight = 0;\nfor (let i = 0; i < this._roots.length; i++) {\n  rootID = this._roots[i];\n  root = this._idToElement.get(rootID);\n  if (root.children.length === 0) {\n    continue;\n  } else if (rootWeight + root.weight > index) {\n    break;\n  } else {\n    rootWeight += root.weight;\n  }\n}\n```\n\nWe skip the root itself because don't display them in the tree:\n```js\nconst firstChildID = root.children[0];\n```\n\nThen we traverse the tree to find the element:\n```js\nlet currentElement = this._idToElement.get(firstChildID);\nlet currentWeight = rootWeight;\nwhile (index !== currentWeight) {\n  for (let i = 0; i < currentElement.children.length; i++) {\n    const childID = currentElement.children[i];\n    const child = this._idToElement.get(childID);\n    const { weight } = child;\n    if (index <= currentWeight + weight) {\n      currentWeight++;\n      currentElement = child;\n      break;\n    } else {\n      currentWeight += weight;\n    }\n  }\n}\n```\n\n## Inspecting an element\n\nWhen an element is mounted in the tree, DevTools sends a minimal amount of information about it across the bridge. This information includes its display name, type, and key- but does _not_ include things like props or state. (These values are often expensive to serialize and change frequently, which would add a significant amount of load to the bridge.)\n\nInstead, DevTools lazily requests additional information about an element only when it is selected in the \"Components\" tab. At that point, the frontend requests this information by sending a special \"_inspectElement_\" message containing the id of the element being inspected. The backend then responds with an \"_inspectedElement_\" message containing the additional details.\n\n### Polling strategy\n\nElements can update frequently, especially in response to things like scrolling events. Since props and state can be large, we avoid sending this information across the bridge every time the selected element is updated. Instead, the frontend polls the backend for updates about once a second. The backend tracks when the element was last \"inspected\" and sends a special no-op response if it has not been re-rendered since then.\n\n### Deeply nested properties\n\nEven when dealing with a single component, serializing deeply nested properties can be expensive. Because of this, DevTools uses a technique referred to as \"dehydration\" to only send a shallow copy of the data on initial inspection. DevTools then fills in the missing data on-demand as a user expands nested objects or arrays. Filled in paths are remembered (for the currently inspected element) so they are not \"dehydrated\" again as part of a polling update.\n\n### Inspecting hooks\n\nHooks present a unique challenge for the DevTools because of the concept of _custom_ hooks. (A custom hook is essentially any function that calls at least one of the built-in hooks. By convention custom hooks also have names that begin with \"use\".)\n\nSo how does DevTools identify custom functions called from within third-party components? It does this by temporarily overriding React's built-in hooks and shallow rendering the component in question. Whenever one of the (overridden) built-in hooks are called, it parses the call stack to spot potential custom hooks (functions between the component itself and the built-in hook). This approach enables it to build a tree structure describing all of the calls to both the built-in _and_ custom hooks, along with the values passed to those hooks. (If you're interested in learning more about this, [here is the source code](https://github.com/facebook/react/blob/main/packages/react-debug-tools/src/ReactDebugHooks.js).)\n\n> **Note**: DevTools obtains hooks info by re-rendering a component.\n> Breakpoints will be invoked during this additional (shallow) render,\n> but DevTools temporarily overrides `console` methods to suppress logging.\n\n### Performance implications\n\nTo mitigate the performance impact of re-rendering a component, DevTools does the following:\n* Only function components that use _at least one hook_ are rendered. (Props and state can be analyzed without rendering.)\n* Rendering is always shallow.\n* Rendering is throttled to occur, at most, once per second.\n* Rendering is skipped if the component has been not updated since the last time its properties were inspected.\n\n## Profiler\n\nDevTools provides a suite of profiling tools for identifying and fixing performance problems. React 16.9+ supports a \"legacy\" profiler and React 18+ adds the [\"timeline\" profiler](https://github.com/facebook/react/tree/main/packages/react-devtools-timeline/src) support. These profilers are explained below, but at a high level– the architecture of each profiler aims to minimize the impact (CPU usage) while profiling is active. This can be accomplished by:\n* Minimizing bridge traffic.\n* Making expensive computations lazy.\n\nThe majority of profiling information is stored in the DevTools backend. The backend push-notifies the frontend of when profiling starts or stops by sending a \"_profilingStatus_\" message. The frontend also asks for the current status after mounting by sending a \"_getProfilingStatus_\" message. (This is done to support the reload-and-profile functionality.)\n\n### Legacy profiler\n\nWhen profiling begins, the frontend takes a snapshot/copy of each root. This snapshot includes the id, name, key, and child IDs for each node in the tree. (This information is already present on the frontend, so it does not require any additional bridge traffic.) While profiling is active, each time React commits– the frontend also stores a copy of the \"_operations_\" message (described above). Once profiling has finished, the frontend can use the original snapshot along with each of the stored \"_operations_\" messages to reconstruct the tree for each of the profiled commits.\n\nWhen profiling begins, the backend records the base durations of each fiber currently in the tree. While profiling is in progress, the backend also stores some information about each commit, including:\n* Commit time and duration\n* Which elements were rendered during that commit\n* Which props and state changed (if enabled in profiler settings)\n\nThis information will eventually be required by the frontend in order to render its profiling graphs, but it will not be sent across the bridge until profiling has been completed (to minimize the performance impact of profiling).\n\n### Timeline profiler\n\nTimeline profiling data can come from one of two places:\n* The React DevTools backend, which injects a [set of profiling hooks](https://github.com/facebook/react/blob/main/packages/react-devtools-shared/src/backend/profilingHooks.js) that React calls while rendering. When profiling, these hooks store information in memory which gets passed to DevTools when profiling is stopped.\n* A Chrome performance export (JSON) containing React data (as User Timing marks) and other browser data like CPU samples, Network traffic, and native commits. (This method is not as convenient but provides more detailed browser performance data.)\n\n### Combining profiling data\n\nOnce profiling is finished, the frontend requests profiling data from the backend one renderer at a time by sending a \"_getProfilingData_\" message. The backend responds with a \"_profilingData_\" message that contains per-root commit timing and duration information. The frontend then combines this information with its own snapshots to form a complete picture of the profiling session. Using this data, charts and graphs are lazily computed (and incrementally cached) on-demand, based on which commits and views are selected in the Profiler UI.\n\n### Importing/exporting data\n\nBecause all of the data is merged in the frontend after a profiling session is completed, it can be exported and imported (as a single JSON object), enabling profiling sessions to be shared between users.\n\n## Package Specific Details\n\n### Devtools Extension Overview Diagram\n\n![React Devtools Extension](https://user-images.githubusercontent.com/2735514/132768489-6ab85156-b816-442f-9c3f-7af738ee9e49.png)\n\n"

    "path": "packages/react-devtools/README.md",
    "content": "# `react-devtools`\n\nThis package can be used to debug non-browser-based React applications (e.g. React Native, mobile browser or embedded webview, Safari).\n\n![React DevTools screenshot](https://user-images.githubusercontent.com/29597/63811956-bdd9b580-c8dd-11e9-8962-c568e475c425.png)\n\n## Installation\nInstall the `react-devtools` package. Because this is a development tool, a global install is often the most convenient:\n```sh\n# Yarn\nyarn global add react-devtools\n\n# NPM\nnpm install -g react-devtools\n```\n\nIf you prefer to avoid global installations, you can add `react-devtools` as a project dependency. With Yarn, you can do this by running:\n```sh\nyarn add --dev react-devtools\n```\n\nWith NPM you can just use [NPX](https://www.npmjs.com/package/npx):\n```sh\nnpx react-devtools\n```\n\n## Usage with React Native\nRun `react-devtools` from the terminal to launch the standalone DevTools app:\n```sh\nreact-devtools\n```\n\nIf you're not using a local simulator, you'll also need to forward ports used by React DevTools:\n```sh\nadb reverse tcp:8097 tcp:8097\n```\n\nIf you're using React Native 0.43 or higher, it should connect to your simulator within a few seconds. (If this doesn't happen automatically, try reloading the React Native app.)\n\n### Integration with React Native Inspector\n\nYou can open the [in-app developer menu](https://reactnative.dev/docs/debugging#accessing-the-in-app-developer-menu) and choose \"Show Inspector\". It will bring up an overlay that lets you tap on any UI element and see information about it:\n\n![React Native Inspector](https://i.imgur.com/ReFhREb.gif)\n\nHowever, when `react-devtools` is running, Inspector will enter a special collapsed mode, and instead use the DevTools as primary UI. In this mode, clicking on something in the simulator will bring up the relevant components in the DevTools:\n\n![React DevTools Inspector Integration](https://user-images.githubusercontent.com/29597/63811958-be724c00-c8dd-11e9-8587-37357334a0e1.gif)\n\n\nYou can choose \"Hide Inspector\" in the same menu to exit this mode.\n\n### Inspecting Component Instances\n\nWhen debugging JavaScript in Chrome, you can inspect the props and state of the React components in the browser console.\n\nFirst, follow the [instructions for debugging in Chrome](https://reactnative.dev/docs/debugging#chrome-developer-tools) to open the Chrome console.\n\nMake sure that the dropdown in the top left corner of the Chrome console says `debuggerWorker.js`. **This step is essential.**\n\nThen select a React component in React DevTools. There is a search box at the top that helps you find one by name. As soon as you select it, it will be available as `$r` in the Chrome console, letting you inspect its props, state, and instance properties.\n\n![React DevTools Chrome Console Integration](https://user-images.githubusercontent.com/29597/63811957-be724c00-c8dd-11e9-9d1d-8eba440ef948.gif)\n\n\n## Usage with React DOM\n\nThe standalone shell can also be useful with React DOM (e.g. to debug apps in Safari or inside of an iframe).\n\nRun `react-devtools` from the terminal to launch the standalone DevTools app:\n```sh\nreact-devtools\n```\n\nAdd `<script src=\"http://localhost:8097\"></script>` as the very first `<script>` tag in the `<head>` of your page when developing:\n\n```html\n<!doctype html>\n<html lang=\"en\">\n  <head>\n    <script src=\"http://localhost:8097\"></script>\n```\n\nThis will ensure the developer tools are connected. **Don’t forget to remove it before deploying to production!**\n\n>If you install `react-devtools` as a project dependency, you may also replace the `<script>` suggested above with a JavaScript import (`import 'react-devtools'`). It is important that this import comes before any other imports in your app (especially before `react-dom`). Make sure to remove the import before deploying to production, as it carries a large DevTools client with it. If you use Webpack and have control over its configuration, you could alternatively add `'react-devtools'` as the first item in the `entry` array of the development-only configuration, and then you wouldn’t need to deal either with `<script>` tags or `import` statements.\n\n## Advanced\n\nBy default DevTools listen to port `8097` on `localhost`. If you need to customize the server or client connection settings, the following environment variables are available:\n\n| Env Var | Default | Description |\n|---|---|---|\n| `HOST` | `\"localhost\"` | Host the local server binds to. |\n| `PORT` | `8097` | Port the local server listens on. |\n| `REACT_DEVTOOLS_PORT` | | Alias for `PORT`. Takes precedence if both are set. |\n| `KEY` | | Path to an SSL key file. Enables HTTPS when set alongside `CERT`. |\n| `CERT` | | Path to an SSL certificate file. Enables HTTPS when set alongside `KEY`. |\n| `REACT_DEVTOOLS_PATH` | | Path appended to the WebSocket URI served to clients (e.g. `/__react_devtools__/`). |\n| `REACT_DEVTOOLS_CLIENT_HOST` | `HOST` | Overrides the host in the script served to connecting clients. |\n| `REACT_DEVTOOLS_CLIENT_PORT` | `PORT` | Overrides the port in the script served to connecting clients. |\n| `REACT_DEVTOOLS_CLIENT_USE_HTTPS` | | Set to `\"true\"` to make the served client script use `wss://`. |\n\nWhen connecting through a reverse proxy, use the `REACT_DEVTOOLS_CLIENT_*` variables to tell clients to connect to a different host/port/protocol than the local server:\n\n```sh\nREACT_DEVTOOLS_CLIENT_HOST=remote.example.com \\\nREACT_DEVTOOLS_CLIENT_PORT=443 \\\nREACT_DEVTOOLS_CLIENT_USE_HTTPS=true \\\nREACT_DEVTOOLS_PATH=/__react_devtools__/ \\\nreact-devtools\n```\n\nFor more details, see the [`react-devtools-core` documentation](https://github.com/facebook/react/tree/main/packages/react-devtools-core).\n\n## FAQ\n\n### The React Tab Doesn't Show Up\n\n**If you are running your app from a local `file://` URL**, don't forget to check \"Allow access to file URLs\" on the Chrome Extensions settings page. You can find it by opening Settings > Extensions:\n\n![Allow access to file URLs](https://user-images.githubusercontent.com/29597/64646784-95b58080-d3cc-11e9-943d-02474683398a.png)\n\nOr you could develop with a local HTTP server like [`serve`](https://www.npmjs.com/package/serve).\n\n**The React tab won't show up if the site doesn't use React**, or if React can't communicate with the devtools. When the page loads, the devtools sets a global named `__REACT_DEVTOOLS_GLOBAL_HOOK__`, then React communicates with that hook during initialization. You can test this on the [React website](https://reactjs.org/) or by inspecting [Facebook](https://www.facebook.com/).\n\n**If your app is inside of CodePen**, make sure you are registered. Then press Fork (if it's not your pen), and then choose Change View > Debug. The Debug view is inspectable with DevTools because it doesn't use an iframe.\n\n**If your app is inside an iframe, a Chrome extension, React Native, or in another unusual environment**, try [the standalone version instead](https://github.com/facebook/react/tree/main/packages/react-devtools). Chrome apps are currently not inspectable.\n\n**If your Components tab is empty, refer to \"The React tab shows no components\" section below**.\n\n**If you still have issues** please [report them](https://github.com/facebook/react/issues/new?labels=Component:%20Developer%20Tools). Don't forget to specify your OS, browser version, extension version, and the exact instructions to reproduce the issue with a screenshot.\n\n### The React tab shows no components\n\n#### The Issue with Chrome v101 and earlier\nAs we migrate to a Chrome Extension Manifest V3, we start to use a new method to hook the DevTools with the inspected page. This new method is more secure, but relies on a new API that's only supported in Chrome v102+. For Chrome v101 or earlier, we use a fallback method, which can cause malfunctions (e.g. failure to load React Elements in the Components tab) if the JS resources on your page is loaded from cache. Please upgrade to Chrome v102+ to avoid this issue.\n\n#### Service Worker malfunction\nGo to chrome://extensions. If you see \"service worker (inactive)\" in the React Developer Tools extension, try disabling and re-enabling the extension. This will restart the service worker. Then go to the page you want to inspect, close the DevTools, and reload the page. Open the DevTools again and the React components tab should be working.\n\n## Local development\nThe standalone DevTools app can be built and tested from source following the instructions below.\n\n### Prerequisite steps\nDevTools depends on local versions of several NPM packages<sup>1</sup> also in this workspace. You'll need to either build or download those packages first.\n\n<sup>1</sup> Note that at this time, an _experimental_ build is required because DevTools depends on the `createRoot` API.\n\n#### Build from source\nTo build dependencies from source, run the following command from the root of the repository:\n```sh\nyarn build-for-devtools\n```\n#### Download from CI\nTo use the latest build from CI, run the following command from the root of the repository:\n```sh\n./scripts/release/download-experimental-build.js\n```\n### Build steps\nYou can test the standalone DevTools by running the following:\n\n* **First, complete the prerequisite steps above! If you don't do it, none of the steps below will work.**\n* Then, run `yarn start:backend` and `yarn start:standalone` in `packages/react-devtools-core`\n* Run `yarn start` in `packages/react-devtools`\n* Refresh the app after it has recompiled a change\n* For React Native, copy `react-devtools-core` to its `node_modules` to test your changes.\n"

    "path": "packages/react-devtools-core/README.md",
    "content": "# `react-devtools-core`\n\nThis package provides low-level APIs to support renderers like [React Native](https://github.com/facebook/react-native). If you're looking for the standalone React DevTools UI, **we suggest using [`react-devtools`](https://github.com/facebook/react/tree/main/packages/react-devtools) instead of using this package directly**.\n\nThis package provides two entrypoints: labeled \"backend\" and \"standalone\" (frontend). Both APIs are described below.\n\n# Backend API\n\nBackend APIs are embedded in _development_ builds of renderers like [React Native](https://github.com/facebook/react-native) in order to connect to the React DevTools UI.\n\n### Example\n\nIf you are building a non-browser-based React renderer, you can use the backend API like so:\n\n```js\nif (process.env.NODE_ENV !== 'production') {\n  const { initialize, connectToDevTools } = require(\"react-devtools-core\");\n\n  initialize(settings);\n  // Must be called before packages like react or react-native are imported\n  connectToDevTools({...config});\n}\n```\n\n> **NOTE** that this API (`connectToDevTools`) must be (1) run in the same context as React and (2) must be called before React packages are imported (e.g. `react`, `react-dom`, `react-native`).\n\n### `initialize` arguments\n| Argument                  | Description |\n|---------------------------|-------------|\n| `settings`                | Optional. If not specified, or received as null, then default settings are used. Can be plain object or a Promise that resolves with the [plain settings object](#Settings). If Promise rejects, the console will not be patched and some console features from React DevTools will not work. |\n| `shouldStartProfilingNow` | Optional. Whether to start profiling immediately after installing the hook. Defaults to `false`. |\n| `profilingSettings`       | Optional. Profiling settings used when `shouldStartProfilingNow` is `true`. Defaults to `{ recordChangeDescriptions: false, recordTimeline: false }`. |\n| `componentFilters`        | Optional. Array or Promise that resolves to an array of component filters to apply before DevTools connects. Defaults to the built-in host component filter. See [Component filters](#component-filters) for the full spec. |\n\n#### `Settings`\n| Spec                                                                                                                                                                           | Default value                                                                                                                                                        |\n|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| <pre>{<br>  appendComponentStack: boolean,<br>  breakOnConsoleErrors: boolean,<br>  showInlineWarningsAndErrors: boolean,<br>  hideConsoleLogsInStrictMode: boolean,<br>  disableSecondConsoleLogDimmingInStrictMode: boolean<br>}</pre> | <pre>{<br>  appendComponentStack: true,<br>  breakOnConsoleErrors: false,<br>  showInlineWarningsAndErrors: true,<br>  hideConsoleLogsInStrictMode: false,<br>  disableSecondConsoleLogDimmingInStrictMode: false<br>}</pre> |\n\n#### Component filters\nEach filter object must include `type` and `isEnabled`. Some filters also require `value` or `isValid`.\n\n| Type | Required fields | Description |\n|------|-----------------|-------------|\n| `ComponentFilterElementType` (`1`) | `type`, `isEnabled`, `value: ElementType` | Hides elements of the given element type. DevTools defaults to hiding host components. |\n| `ComponentFilterDisplayName` (`2`) | `type`, `isEnabled`, `isValid`, `value: string` | Hides components whose display name matches the provided RegExp string. |\n| `ComponentFilterLocation` (`3`) | `type`, `isEnabled`, `isValid`, `value: string` | Hides components whose source location matches the provided RegExp string. |\n| `ComponentFilterHOC` (`4`) | `type`, `isEnabled`, `isValid` | Hides higher-order components. |\n| `ComponentFilterEnvironmentName` (`5`) | `type`, `isEnabled`, `isValid`, `value: string` | Hides components whose environment name matches the provided string. |\n| `ComponentFilterActivitySlice` (`6`) | `type`, `isEnabled`, `isValid`, `activityID`, `rendererID` | Filters activity slices; usually managed by DevTools rather than user code. |\n\n### `connectToDevTools` options\n| Prop                   | Default       | Description                                                                                                               |\n|------------------------|---------------|---------------------------------------------------------------------------------------------------------------------------|\n| `host`                 | `\"localhost\"` | Socket connection to frontend should use this host.                                                                       |\n| `isAppActive`          |               | (Optional) function that returns true/false, telling DevTools when it's ready to connect to React.                        |\n| `path`                 | `\"\"`          | Path appended to the WebSocket URI (e.g. `\"/__react_devtools__/\"`).

One example of this is [`react-devtools`](https://github.com/facebook/react/tree/main/packages/react-devtools) which wraps DevTools in an Electron app.\n\n### Example\n```js\nimport DevtoolsUI from \"react-devtools-core/standalone\";\n\n// See the full list of API methods in documentation below.\nconst { setContentDOMNode, startServer } = DevtoolsUI;\n\n// Render DevTools UI into a DOM element.\nsetContentDOMNode(document.getElementById(\"container\"));\n\n// Start socket server used to communicate between backend and frontend.\nstartServer(\n  // Port defaults to 8097\n  1234,\n\n  // Host defaults to \"localhost\"\n  \"example.devserver.com\",\n\n  // Optional config for secure socket (WSS).\n  {\n    key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),\n    cert: fs.readFileSync('test/fixtures/keys/agent2-cert.pem')\n  }\n);\n```\n\n### Exported methods\nThe `default` export is an object defining the methods described below.\n\nThese methods support chaining for convenience. For example:\n```js\nconst DevtoolsUI = require(\"react-devtools-core/standalone\");\nDevtoolsUI.setContentDOMNode(element).startServer();\n```\n\n#### `connectToSocket(socket: WebSocket)`\n> This is an advanced config function that is typically not used.\n\nCustom `WebSocket` connection to use for communication between DevTools frontend and backend. Calling this method automatically initializes the DevTools UI (similar to calling `startServer()`).\n\n#### `openProfiler()`\nAutomatically select the \"Profiler\" tab in the DevTools UI.\n\n#### `setContentDOMNode(element: HTMLElement)`\nSet the DOM element DevTools UI should be rendered into on initialization.\n\n#### `setDisconnectedCallback(callback: Function)`\n_Optional_ callback to be notified when DevTools `WebSocket` closes (or errors).\n\n#### `setProjectRoots(roots: Array<string>)`\n_Optional_ set of root directories for source files. These roots can be used to open an inspected component's source code using an IDE.\n\n#### `setStatusListener(callback: Function)`\n_Optional_ callback to be notified of socket server events (e.g. initialized, errored, connected).\n\nThis callback receives two parameters:\n```js\nfunction onStatus(\n  message: string,\n  status: 'server-connected' | 'devtools-connected' | 'error'\n): void {\n  // ...\n}\n```\n\n#### `startServer(port?, host?, httpsOptions?, loggerOptions?, path?, clientOptions?)`\nStart a socket server (used to communicate between backend and frontend) and renders the DevTools UI.\n\nThis method accepts the following parameters:\n| Name | Default | Description |\n|---|---|---|\n| `port` | `8097` | Port the local server listens on. |\n| `host` | `\"localhost\"` | Host the local server binds to. |\n| `httpsOptions` | | _Optional_ object defining `key` and `cert` strings. |\n| `loggerOptions` | | _Optional_ object defining a `surface` string (to be included with DevTools logging events). |\n| `path` | | _Optional_ path to append to the WebSocket URI served to connecting clients (e.g. `\"/__react_devtools__/\"`). Also set via the `REACT_DEVTOOLS_PATH` env var in the Electron app. |\n| `clientOptions` | | _Optional_ object with client-facing overrides (see below). |\n\n##### `clientOptions`\n\nWhen connecting through a reverse proxy, the client may need to connect to a different host, port, or protocol than the local server. Use `clientOptions` to override what appears in the `connectToDevTools()` script served to clients. Any field not set falls back to the corresponding server value.\n\n| Field | Default | Description |\n|---|---|---|\n| `host` | server `host` | Host the client connects to. |\n| `port` | server `port` | Port the client connects to. |\n| `useHttps` | server `useHttps` | Whether the client should use `wss://`. |\n\nThese can also be set via environment variables in the Electron app:\n\n| Env Var | Description |\n|---|---|\n| `REACT_DEVTOOLS_CLIENT_HOST` | Overrides the host in the served client script. |\n| `REACT_DEVTOOLS_CLIENT_PORT` | Overrides the port in the served client script. |\n| `REACT_DEVTOOLS_CLIENT_USE_HTTPS` | Set to `\"true\"` to make the served client script use `wss://`. |\n\n##### Reverse proxy example\n\nRun DevTools locally on the default port, but tell clients to connect through a remote proxy:\n```sh\nREACT_DEVTOOLS_CLIENT_HOST=remote.example.com \\\nREACT_DEVTOOLS_CLIENT_PORT=443 \\\nREACT_DEVTOOLS_CLIENT_USE_HTTPS=true \\\nREACT_DEVTOOLS_PATH=/__react_devtools__/ \\\nreact-devtools\n```\nThe server listens on `localhost:8097`. The served script tells clients:\n```js\nconnectToDevTools({host: 'remote.example.com', port: 443, useHttps: true, path: '/__react_devtools__/'})\n```\n\n# Development\n\nWatch for changes made to the backend entry point and rebuild:\n```sh\nyarn start:backend\n```\n\nWatch for changes made to the standalone UI entry point and rebuild:\n```sh\nyarn start:standalone\n```\n\nRun the standalone UI using `yarn start` in the [`react-devtools`](https://github.com/facebook/react/tree/main/packages/react-devtools).\n"

You'll need to either build or download those packages first.\n\n<sup>1</sup> Note that at this time, an _experimental_ build is required because DevTools depends on the `createRoot` API.\n\nTo install all necessary dependencies, run the following command from the root of the repository:\n\n```sh\nyarn install\n```\n\n#### Build from source\nTo build dependencies from source, run the following command from the root of the repository:\n```sh\nyarn build-for-devtools\n```\n#### Download from CI\nTo use the latest build from CI, run the following commands starting from the root of the repository:\n```sh\ncd scripts/release\nyarn install\n./download-experimental-build.js\n```\n### Build steps\nOnce the above packages have been built or downloaded, you can build the extension by running:\n```sh\ncd packages/react-devtools-extensions/\n\nyarn build:chrome # => packages/react-devtools-extensions/chrome/build\nyarn run test:chrome # Test Chrome extension\n\nyarn build:firefox # => packages/react-devtools-extensions/firefox/build\nyarn run test:firefox # Test Firefox extension\n\nyarn build:edge # => packages/react-devtools-extensions/edge/build\nyarn run test:edge # Test Edge extension\n```\n"

    "content": "# `react-devtools-inline`\n\nThis package can be used to embed React DevTools into browser-based tools like [CodeSandbox](https://codesandbox.io/), [StackBlitz](https://stackblitz.com/), and [Replay](https://replay.io).\n\nIf you're looking for the standalone React DevTools UI, **we suggest using [`react-devtools`](https://github.com/facebook/react/tree/main/packages/react-devtools) instead of using this package directly**.\n\n---\n\n> **Note** that this package (and the DevTools UI) relies on several _experimental_ APIs that are **only available in the [experimental release channel](https://reactjs.org/docs/release-channels.html#experimental-channel)**. This means that you will need to install `react@experimental` and `react-dom@experimental`.\n\n---\n\n# Usage\n\nThis package exports two entry points: a frontend (to be run in the main `window`) and a backend (to be installed and run within an `iframe`<sup>1</sup>).\n\nThe frontend and backend can be initialized in any order, but **the backend must not be activated until the frontend initialization has completed**. Because of this, the simplest sequence is:\n\n1. Frontend (DevTools interface) initialized in the main `window`.\n1. Backend initialized in an `iframe`.\n1. Backend activated.\n\n<sup>1</sup> Sandboxed iframes are supported.\n\n# Backend APIs\n### `initialize(windowOrGlobal)`\n\nInstalls the global hook on the window/global object. This hook is how React and DevTools communicate.\n\n> **This method must be called before React is loaded.** (This includes `import`/`require` statements and `<script>` tags that include React.)\n\n### `activate(windowOrGlobal)`\n\nLets the backend know when the frontend is ready. It should not be called until after the frontend has been initialized, else the frontend might miss important tree-initialization events.\n\n### Example\n```js\nimport { activate, initialize } from 'react-devtools-inline/backend';\n\n// This should be the iframe the React application is running in.\nconst iframe = document.getElementById(frameID);\nconst contentWindow = iframe.contentWindow;\n\n// Call this before importing React (or any other packages that might import React).\ninitialize(contentWindow);\n\n// Initialize the frontend...\n\n// Call this only once the frontend has been initialized.\nactivate(contentWindow);\n```\n\n# Frontend APIs\n\n### `initialize(windowOrGlobal)`\nConfigures the DevTools interface to listen to the `window` (or `global` object) the backend was injected into. This method returns a React component that can be rendered directly.\n\n> Because the DevTools interface makes use of several new React concurrent features (like Suspense) **it should be rendered using `ReactDOMClient.createRoot` instead of `ReactDOM.render`.**\n\n### Example\n```js\nimport { initialize } from 'react-devtools-inline/frontend';\n\n// This should be the iframe the backend hook has been installed in.\nconst iframe = document.getElementById(frameID);\nconst contentWindow = iframe.contentWindow;\n\n// This returns a React component that can be rendered into your app.\n// e.g. render(<DevTools {...props} />);\nconst DevTools = initialize(contentWindow);\n```\n\n# Advanced examples\n\n### Supporting named hooks\n\nDevTools can display hook \"names\" for an inspected component, although determining the \"names\" requires loading the source (and source-maps), parsing the code, and inferring the names based on which variables hook values get assigned to. Because the code for this is non-trivial, it's lazy-loaded only if the feature is enabled.\n\nTo configure this package to support this functionality, you'll need to provide a prop that dynamically imports the extra functionality:\n```js\n// Follow code examples above to configure the backend and frontend.\n// When rendering DevTools, the important part is to pass a 'hookNamesModuleLoaderFunction' prop.\nconst hookNamesModuleLoaderFunction = () => import('react-devtools-inline/hookNames');\n\n// Render:\n<DevTools\n  hookNamesModuleLoaderFunction={hookNamesModuleLoaderFunction}\n  {...otherProps}\n/>;\n```\n\n### Configuring a same-origin `iframe`\n\nThe simplest way to use this package is to install the hook from the parent `window`. This is possible if the `iframe` is not sandboxed and there are no cross-origin restrictions.\n\n```js\nimport {\n  activate as activateBackend,\n  initialize as initializeBackend\n} from 'react-devtools-inline/backend';\nimport { initialize as initializeFrontend } from 'react-devtools-inline/frontend';\n\n// The React app you want to inspect with DevTools is running within this iframe:\nconst iframe = document.getElementById('target');\nconst { contentWindow } = iframe;\n\n// Installs the global hook into the iframe.\n// This must be called before React is loaded into that frame.\ninitializeBackend(contentWindow);\n\n// Initialize DevTools UI to listen to the hook we just installed.\n// This returns a React component we can render anywhere in the parent window.\n// This also must be called before React is loaded into the iframe\nconst DevTools = initializeFrontend(contentWindow);\n\n// React application can be injected into <iframe> at any time now...\n// Note that this would need to be done via <script> tag injection,\n// as setting the src of the <iframe> would load a new page (without the injected backend).\n\n// <DevTools /> interface can be rendered in the parent window at any time now...\n// Be sure to use ReactDOMClient.createRoot() to render this component.\n\n// Let the backend know the frontend is ready and listening.\nactivateBackend(contentWindow);\n```\n\n### Configuring a sandboxed `iframe`\n\nSandboxed `iframe`s are also supported but require more complex initialization.\n\n**`iframe.html`**\n```js\nimport { activate, initialize } from \"react-devtools-inline/backend\";\n\n// The DevTools hook needs to be installed before React is even required!\n// The safest way to do this is probably to install it in a separate script tag.\ninitialize(window);\n\n// Wait for the frontend to let us know that it's ready.\nfunction onMessage({ data }) {\n  switch (data.type) {\n    case \"activate-backend\":\n      window.removeEventListener(\"message\", onMessage);\n\n      activate(window);\n      break;\n    default:\n      break;\n  }\n}\n\nwindow.addEventListener(\"message\", onMessage);\n```\n\n**`main-window.html`**\n```js\nimport { initialize } from \"react-devtools-inline/frontend\";\n\nconst iframe = document.getElementById(\"target\");\nconst { contentWindow } = iframe;\n\n// Initialize DevTools UI to listen to the iframe.\n// This returns a React component we can render anywhere in the main window.\n// Be sure to use ReactDOMClient.createRoot() to render this component.\nconst DevTools = initialize(contentWindow);\n\n// Let the backend know to initialize itself.\n// We can't do this directly because the iframe is sandboxed.\n// Only initialize the backend once the DevTools frontend has been initialized.\niframe.onload = () => {\n  contentWindow.postMessage(\n    {\n      type: \"activate-backend\"\n    },\n    \"*\"\n  );\n};\n```\n\n### Advanced: Custom \"wall\"\n\nBelow is an example of an advanced integration with a website like [Replay.io](https://replay.io/) or Code Sandbox's Sandpack (where more than one DevTools instance may be rendered per page).\n\n```js\nimport {\n  activate as activateBackend,\n  createBridge as createBackendBridge,\n  initialize as initializeBackend,\n} from 'react-devtools-inline/backend';\nimport {\n  createBridge as createFrontendBridge,\n  createStore,\n  initialize as createDevTools,\n} from 'react-devtools-inline/frontend';\n\n// DevTools uses \"message\" events and window.postMessage() by default,\n// but we can override this behavior by creating a custom \"Wall\" object.\n// For example...\nconst wall = {\n  _listeners: [],\n  listen(listener) {\n    wall._listeners.push(listener);\n  },\n  send(event, payload) {\n    wall._listeners.forEach(listener => listener({event, payload}));\n  },\n};\n\n// Initialize the DevTools backend before importing React (or any other packages that might import React).\ninitializeBackend(contentWindow);\n\n// Prepare DevTools for rendering.\n// To use the custom Wall we've created, we need to also create our own \"Bridge\" and \"Store\" objects.\nconst bridge = createFrontendBridge(contentWindow, wall);\nconst store = createStore(bridge);\nconst DevTools = createDevTools(contentWindow, { bridge, store });\n\n// You can render DevTools now:\nconst root = createRoot(container);\nroot.render(<DevTools {...otherProps} />);\n\n// Lastly, let the DevTools backend know that the frontend is ready.\n// To use the custom Wall we've created, we need to also pass in the \"Bridge\".\nactivateBackend(contentWindow, {\n  bridge: createBackendBridge(contentWindow, wall),\n});\n```\n\nAlternately, if your code can't share the same `wall` object, you can still provide a custom Wall that connects a specific DevTools frontend to a specific backend like so:\n```js\nconst uid = \"some-unique-string-shared-between-both-pieces\";\nconst wall = {\n  listen(listener) {\n    window.addEventListener(\"message\", (event) => {\n      if (event.data.uid === uid) {\n        listener(event.data);\n      }\n    });\n  },\n  send(event, payload) {\n    window.postMessage({ event, payload, uid }, \"*\");\n  },\n};\n```\n\n### Advanced: Node + browser\n\nBelow is an example of an advanced integration that could be used to connect React running in a Node process to React DevTools running in a browser.\n\n##### Sample Node backend\n```js\nconst {\n  activate,\n  createBridge,\n  initialize,\n} = require('react-devtools-inline/backend');\nconst { createServer } = require('http');\nconst SocketIO = require('socket.io');\n\nconst server = createServer();\nconst socket = SocketIO(server, {\n  cors: {\n    origin: \"*\",\n    methods: [\"GET\", \"POST\"],\n    allowedHeaders: [],\n    credentials: true\n  }\n});\nsocket.on('connection', client => {\n  const wall = {\n    listen(listener) {\n      client.on('message', data => {\n        if (data.uid === UID) {\n          listener(data);\n        }\n      });\n    },\n    send(event, payload) {\n      const data = {event, payload, uid: UID};\n      client.emit('message', data);\n    },\n  };\n\n  const bridge = createBridge(global, wall);\n\n  client.on('disconnect', () => {\n    bridge.shutdown();\n  });\n\n  activate(global, { bridge });\n});\nsocket.listen(PORT);\n```\n\n##### Sample Web frontend\n```js\nimport { createElement } from 'react';\nimport { createRoot } from 'react-dom/client';\nimport {\n  createBridge,\n  createStore,\n  initialize as createDevTools,\n} from 'react-devtools-inline/frontend';\nimport { io } from \"socket.io-client\";\n\nlet root = null;\n\nconst socket = io(`http://${HOST}:${PORT}`);\nsocket.on(\"connect\", () => {\n  const wall = {\n    listen(listener) {\n      socket.on(\"message\", (data) => {\n        if (data.uid === UID) {\n          listener(data);\n        }\n      });\n    },\n    send(event, payload) {\n      const data = { event, payload, uid: UID };\n      socket.emit('message', data);\n    },\n  };\n\n  const bridge = createBridge(window, wall);\n  const store = createStore(bridge);\n  const DevTools = createDevTools(window, { bridge, store });\n\n  root = createRoot(document.getElementById('root'));\n  root.render(createElement(DevTools));\n});\nsocket.on(\"disconnect\", () => {\n  root.unmount();\n  root = null;\n});\n```\n\n# Local development\nYou can also build and test this package from source.\n\n## Prerequisite steps\nDevTools depends on local versions of several NPM packages<sup>1</sup> also in this workspace. You'll need to either build or download those packages first.\n\n<sup>1</sup> Note that at this time, an _experimental_ build is required because DevTools depends on the `createRoot` API.\n\n### Build from source\nTo build dependencies from source, run the following command from the root of the repository:\n```sh\nyarn build-for-devtools\n```\n### Download from CI\nTo use the latest build from CI, go to `scripts/release/` and run the following commands:\n```sh\nyarn\n./download-experimental-build.js --commit=main\n```\n\n## Build steps\nOnce the above packages have been built or downloaded, you can watch for changes made to the source code and automatically rebuild by running:\n```sh\nyarn start\n```\n\nTo test package changes, refer to the [`react-devtools-shell` README](https://github.com/facebook/react/blob/main/packages/react-devtools-shell/README.md).\n"

It cannot use Client Components and does not hydrate. It is intended to be paired with the generic React package, which is shipped as `react` to npm.\n\n## Installation\n\n```sh\nnpm install react react-markup\n```\n\n## Usage\n\n```js\nimport { experimental_renderToHTML as renderToHTML } from 'react-markup';\nimport EmailTemplate from './my-email-template-component.js'\n\nasync function action(email, name) {\n  \"use server\";\n  // ... in your server, e.g. a Server Action...\n  const htmlString = await renderToHTML(<EmailTemplate name={name} />);\n  // ... send e-mail using some e-mail provider\n  await sendEmail({ to: email, contentType: 'text/html', body: htmlString });\n}\n```\n\nNote that this is an async function that needs to be awaited - unlike the legacy `renderToString` in `react-dom`.\n\n## API\n\n### `react-markup`\n\nSee https://react.dev/reference/react-markup\n\n## Thanks\n\nThe React team thanks [Nikolai Mavrenkov](https://www.koluch.ru/) for donating the `react-markup` package name.\n"

following order:\n *\n * `[R, S, C]`\n *\n * To help illustrate the example, assume `S` is `SimpleEventPlugin` (for\n * `onClick` etc) and `R` is `ResponderEventPlugin`.\n *\n * \"Deferred-Dispatched Events\":\n *\n * - The current event plugin system will traverse the list of injected plugins,\n *   in order, and extract events by collecting the plugin's return value of\n *   `extractEvents()`.\n * - These events that are returned from `extractEvents` are \"deferred\n *   dispatched events\".\n * - When returned from `extractEvents`, deferred-dispatched events contain an\n *   \"accumulation\" of deferred dispatches.\n * - These deferred dispatches are accumulated/collected before they are\n *   returned, but processed at a later time by the `EventPluginRegistry` (hence the\n *   name deferred).\n *\n * In the process of returning their deferred-dispatched events, event plugins\n * themselves can dispatch events on-demand without returning them from\n * `extractEvents`. Plugins might want to do this, so that they can use event\n * dispatching as a tool that helps them decide which events should be extracted\n * in the first place.\n *\n * \"On-Demand-Dispatched Events\":\n *\n * - On-demand-dispatched events are not returned from `extractEvents`.\n * - On-demand-dispatched events are dispatched during the process of returning\n *   the deferred-dispatched events.\n * - They should not have side effects.\n * - They should be avoided, and/or eventually be replaced with another\n *   abstraction that allows event plugins to perform multiple \"rounds\" of event\n *   extraction.\n *\n * Therefore, the sequence of event dispatches becomes:\n *\n * - `R`s on-demand events (if any)   (dispatched by `R` on-demand)\n * - `S`s on-demand events (if any)   (dispatched by `S` on-demand)\n * - `C`s on-demand events (if any)   (dispatched by `C` on-demand)\n * - `R`s extracted events (if any)   (dispatched by `EventPluginRegistry`)\n * - `S`s extracted events (if any)   (dispatched by `EventPluginRegistry`)\n * - `C`s extracted events (if any)   (dispatched by `EventPluginRegistry`)\n *\n * In the case of `ResponderEventPlugin`: If the `startShouldSetResponder`\n * on-demand dispatch returns `true` (and some other details are satisfied) the\n * `onResponderGrant` deferred dispatched event is returned from\n * `extractEvents`. The sequence of dispatch executions in this case\n * will appear as follows:\n *\n * - `startShouldSetResponder` (`ResponderEventPlugin` dispatches on-demand)\n * - `touchStartCapture`       (`EventPluginRegistry` dispatches as usual)\n * - `touchStart`              (`EventPluginRegistry` dispatches as usual)\n * - `responderGrant/Reject`   (`EventPluginRegistry` dispatches as usual)\n */\n\nfunction setResponderAndExtractTransfer(\n  topLevelType,\n  targetInst,\n  nativeEvent,\n  nativeEventTarget,\n) {\n  const shouldSetEventType = isStartish(topLevelType)\n    ? eventTypes.startShouldSetResponder\n    : isMoveish(topLevelType)\n      ? eventTypes.moveShouldSetResponder\n      : topLevelType === TOP_SELECTION_CHANGE\n        ? eventTypes.selectionChangeShouldSetResponder\n        : eventTypes.scrollShouldSetResponder;\n\n  // TODO: stop one short of the current responder.\n  const bubbleShouldSetFrom = !responderInst\n    ? targetInst\n    : getLowestCommonAncestor(responderInst, targetInst);\n\n  // When capturing/bubbling the \"shouldSet\" event, we want to skip the target\n  // (deepest ID) if it happens to be the current responder.

    "content": "# react-reconciler\n\nThis is an experimental package for creating custom React renderers.\n\n**Its API is not as stable as that of React, React Native, or React DOM, and does not follow the common versioning scheme.**\n\n**Use it at your own risk.**\n\n## Usage\n\n```js\nconst Reconciler = require('react-reconciler');\n\nconst HostConfig = {\n  // You'll need to implement some methods here.\n  // See below for more information and examples.\n};\n\nconst MyRenderer = Reconciler(HostConfig);\n\nconst RendererPublicAPI = {\n  render(element, container, callback) {\n    // Call MyRenderer.updateContainer() to schedule changes on the roots.\n    // See ReactDOM, React Native, or React ART for practical examples.\n  }\n};\n\nmodule.exports = RendererPublicAPI;\n```\n\n## Practical Examples\n\nA \"host config\" is an object that you need to provide, and that describes how to make something happen in the \"host\" environment (e.g. DOM, canvas, console, or whatever your rendering target is). It looks like this:\n\n```js\nconst HostConfig = {\n  createInstance(type, props) {\n    // e.g. DOM renderer returns a DOM node\n  },\n  // ...\n  supportsMutation: true, // it works by mutating nodes\n  appendChild(parent, child) {\n    // e.g. DOM renderer would call .appendChild() here\n  },\n  // ...\n};\n```\n\n**For an introduction to writing a very simple custom renderer, check out this article series:**\n\n* **[Building a simple custom renderer to DOM](https://medium.com/@agent_hunt/hello-world-custom-react-renderer-9a95b7cd04bc)**\n* **[Building a simple custom renderer to native](https://medium.com/@agent_hunt/introduction-to-react-native-renderers-aka-react-native-is-the-java-and-react-native-renderers-are-828a0022f433)**\n\nThe full list of supported methods [can be found here](https://github.com/facebook/react/blob/main/packages/react-reconciler/src/forks/ReactFiberConfig.custom.js). For their signatures, we recommend looking at specific examples below.\n\nThe React repository includes several renderers. Each of them has its own host config.\n\nThe examples in the React repository are declared a bit differently than a third-party renderer would be. In particular, the `HostConfig` object mentioned above is never explicitly declared, and instead is a *module* in our code. However, its exports correspond directly to properties on a `HostConfig` object you'd need to declare in your code:\n\n* [React ART](https://github.com/facebook/react/blob/main/packages/react-art/src/ReactART.js) and its [host config](https://github.com/facebook/react/blob/main/packages/react-art/src/ReactFiberConfigART.js)\n* [React DOM](https://github.com/facebook/react/blob/main/packages/react-dom/src/client/ReactDOM.js) and its [host config](https://github.com/facebook/react/blob/main/packages/react-dom-bindings/src/client/ReactFiberConfigDOM.js)\n* [React Native](https://github.com/facebook/react/blob/main/packages/react-native-renderer/src/ReactFabric.js) and its [host config](https://github.com/facebook/react/blob/main/packages/react-native-renderer/src/ReactFiberConfigFabric.js)\n\nIf these links break please file an issue and we’ll fix them. They intentionally link to the latest versions since the API is still evolving. If you have more questions please file an issue and we’ll try to help!\n\n## An (Incomplete!) Reference\n\nAt the moment, we can't commit to documenting every API detail because the host config still changes very often between the releases. The documentation below is **provided in the spirit of making our best effort rather than an API guarantee**. It focuses on the parts that don't change too often. This is a compromise that strikes a balance between the need for a fast-paced development of React itself, and the usefulness of this package to the custom renderer community. If you notice parts that are out of date or don't match how the latest stable update is behaving, please file an issue or send a pull request, although a response might take time.\n\n#### Modes\n\nThe reconciler has two modes: mutation mode and persistent mode. You must specify one of them.\n\nIf your target platform is similar to the DOM and has methods similar to `appendChild`, `removeChild`, and so on, you'll want to use the **mutation mode**. This is the same mode used by React DOM, React ART, and the classic React Native renderer.\n\n```js\nconst HostConfig = {\n  // ...\n  supportsMutation: true,\n  // ...\n}\n```\n\nIf your target platform has immutable trees, you'll want the **persistent mode** instead. In that mode, existing nodes are never mutated, and instead every change clones the parent tree and then replaces the whole parent tree at the root. This is the mode used by the new React Native renderer, codenamed \"Fabric\".\n\n```js\nconst HostConfig = {\n  // ...\n  supportsPersistence: true,\n  // ...\n}\n```\n\nDepending on the mode, the reconciler will call different methods on your host config.\n\nIf you're not sure which one you want, you likely need the mutation mode.\n\n#### Core Methods\n\n#### `createInstance(type, props, rootContainer, hostContext, internalHandle)`\n\nThis method should return a newly created node. For example, the DOM renderer would call `document.createElement(type)` here and then set the properties from `props`.\n\nYou can use `rootContainer` to access the root container associated with that tree. For example, in the DOM renderer, this is useful to get the correct `document` reference that the root belongs to.\n\nThe `hostContext` parameter lets you keep track of some information about your current place in the tree. To learn more about it, see `getChildHostContext` below.\n\nThe `internalHandle` data structure is meant to be opaque. If you bend the rules and rely on its internal fields, be aware that it may change significantly between versions. You're taking on additional maintenance risk by reading from it, and giving up all guarantees if you write something to it.\n\nThis method happens **in the render phase**. It can (and usually should) mutate the node it has just created before returning it, but it must not modify any other nodes. It must not register any event handlers on the parent tree. This is because an instance being created doesn't guarantee it would be placed in the tree — it could be left unused and later collected by GC. If you need to do something when an instance is definitely in the tree, look at `commitMount` instead.\n\n#### `createTextInstance(text, rootContainer, hostContext, internalHandle)`\n\nSame as `createInstance`, but for text nodes. If your renderer doesn't support text nodes, you can throw here.\n\n#### `appendInitialChild(parentInstance, child)`\n\nThis method should mutate the `parentInstance` and add the child to its list of children. For example, in the DOM this would translate to a `parentInstance.appendChild(child)` call.\n\nThis method happens **in the render phase**. It can mutate `parentInstance` and `child`, but it must not modify any other nodes. It's called while the tree is still being built up and not connected to the actual tree on the screen.\n\n#### `finalizeInitialChildren(instance, type, props, rootContainer, hostContext)`\n\nIn this method, you can perform some final mutations on the `instance`. Unlike with `createInstance`, by the time `finalizeInitialChildren` is called, all the initial children have already been added to the `instance`, but the instance itself has not yet been connected to the tree on the screen.\n\nThis method happens **in the render phase**. It can mutate `instance`, but it must not modify any other nodes. It's called while the tree is still being built up and not connected to the actual tree on the screen.\n\nThere is a second purpose to this method. It lets you specify whether there is some work that needs to happen when the node is connected to the tree on the screen. If you return `true`, the instance will receive a `commitMount` call later. See its documentation below.\n\nIf you don't want to do anything here, you should return `false`.\n\n#### `shouldSetTextContent(type, props)`\n\nSome target platforms support setting an instance's text content without manually creating a text node. For example, in the DOM, you can set `node.textContent` instead of creating a text node and appending it.\n\nIf you return `true` from this method, React will assume that this node's children are text, and will not create nodes for them. It will instead rely on you to have filled that text during `createInstance`. This is a performance optimization. For example, the DOM renderer returns `true` only if `type` is a known text-only parent (like `'textarea'`) or if `props.children` has a `'string'` type. If you return `true`, you will need to implement `resetTextContent` too.\n\nIf you don't want to do anything here, you should return `false`.\n\nThis method happens **in the render phase**. Do not mutate the tree from it.\n\n#### `getRootHostContext(rootContainer)`\n\nThis method lets you return the initial host context from the root of the tree. See `getChildHostContext` for the explanation of host context.\n\nIf you don't intend to use host context, you can return `null`.\n\nThis method happens **in the render phase**. Do not mutate the tree from it.\n\n#### `getChildHostContext(parentHostContext, type, rootContainer)`\n\nHost context lets you track some information about where you are in the tree so that it's available inside `createInstance` as the `hostContext` parameter. For example, the DOM renderer uses it to track whether it's inside an HTML or an SVG tree, because `createInstance` implementation needs to be different for them.\n\nIf the node of this `type` does not influence the context you want to pass down, you can return `parentHostContext`. Alternatively, you can return any custom object representing the information you want to pass down.\n\nIf you don't want to do anything here, return `parentHostContext`.\n\nThis method happens **in the render phase**. Do not mutate the tree from it.\n\n#### `getPublicInstance(instance)`\n\nDetermines what object gets exposed as a ref. You'll likely want to return the `instance` itself. But in some cases it might make sense to only expose some part of it.\n\nIf you don't want to do anything here, return `instance`.\n\n#### `prepareForCommit(containerInfo)`\n\nThis method lets you store some information before React starts making changes to the tree on the screen. For example, the DOM renderer stores the current text selection so that it can later restore it. This method is mirrored by `resetAfterCommit`.\n\nEven if you don't want to do anything here, you need to return `null` from it.\n\n#### `resetAfterCommit(containerInfo)`\n\nThis method is called right after React has performed the tree mutations. You can use it to restore something you've stored in `prepareForCommit` — for example, text selection.\n\nYou can leave it empty.\n\n#### `preparePortalMount(containerInfo)`\n\nThis method is called for a container that's used as a portal target. Usually you can leave it empty.\n\n#### `scheduleTimeout(fn, delay)`\n\nYou can proxy this to `setTimeout` or its equivalent in your environment.\n\n#### `cancelTimeout(id)`\n\nYou can proxy this to `clearTimeout` or its equivalent in your environment.\n\n#### `noTimeout`\n\nThis is a property (not a function) that should be set to something that can never be a valid timeout ID. For example, you can set it to `-1`.\n\n#### `supportsMicrotasks`\n\nSet this to true to indicate that your renderer supports `scheduleMicrotask`. We use microtasks as part of our discrete event implementation in React DOM. If you're not sure if your renderer should support this, you probably should. The option to not implement `scheduleMicrotask` exists so that platforms with more control over user events, like React Native, can choose to use a different mechanism.\n#### `scheduleMicrotask(fn)`\n\nOptional. You can proxy this to `queueMicrotask` or its equivalent in your environment.\n\n#### `isPrimaryRenderer`\n\nThis is a property (not a function) that should be set to `true` if your renderer is the main one on the page. For example, if you're writing a renderer for the Terminal, it makes sense to set it to `true`, but if your renderer is used *on top of* React DOM or some other existing renderer, set it to `false`.\n\n#### `getCurrentEventPriority`\n\nTo implement this method, you'll need some constants available on the special `react-reconciler/constants` entry point:\n\n```js\nimport {\n  DiscreteEventPriority,\n  ContinuousEventPriority,\n  DefaultEventPriority,\n} from 'react-reconciler/constants';\n\nconst HostConfig = {\n  // ...\n  getCurrentEventPriority() {\n    return DefaultEventPriority;\n  },\n  // ...\n}\n\nconst MyRenderer = Reconciler(HostConfig);\n```\n\nThe constant you return depends on which event, if any, is being handled right now. (In the browser, you can check this using `window.event && window.event.type`).\n\n* **Discrete events:** If the active event is _directly caused by the user_ (such as mouse and keyboard events) and _each event in a sequence is intentional_ (e.g. `click`), return `DiscreteEventPriority`. This tells React that they should interrupt any background work and cannot be batched across time.\n\n* **Continuous events:** If the active event is _directly caused by the user_ but _the user can't distinguish between individual events in a sequence_ (e.g. `mouseover`), return `ContinuousEventPriority`. This tells React they should interrupt any background work but can be batched across time.\n\n* **Other events / No active event:** In all other cases, return `DefaultEventPriority`. This tells React that this event is considered background work, and interactive events will be prioritized over it.\n\nYou can consult the `getCurrentEventPriority()` implementation in `ReactFiberConfigDOM.js` for a reference implementation.\n\n### Mutation Methods\n\nIf you're using React in mutation mode (you probably do), you'll need to implement a few more methods.\n\n#### `appendChild(parentInstance, child)`\n\nThis method should mutate the `parentInstance` and add the child to its list of children. For example, in the DOM this would translate to a `parentInstance.appendChild(child)` call.\n\nAlthough this method currently runs in the commit phase, you still should not mutate any other nodes in it. If you need to do some additional work when a node is definitely connected to the visible tree, look at `commitMount`.\n\n#### `appendChildToContainer(container, child)`\n\nSame as `appendChild`, but for when a node is attached to the root container. This is useful if attaching to the root has a slightly different implementation, or if the root container nodes are of a different type than the rest of the tree.\n\n#### `insertBefore(parentInstance, child, beforeChild)`\n\nThis method should mutate the `parentInstance` and place the `child` before `beforeChild` in the list of its children. For example, in the DOM this would translate to a `parentInstance.insertBefore(child, beforeChild)` call.\n\nNote that React uses this method both for insertions and for reordering nodes. Similar to DOM, it is expected that you can call `insertBefore` to reposition an existing child. Do not mutate any other parts of the tree from it.\n\n#### `insertInContainerBefore(container, child, beforeChild)`\n\nSame as `insertBefore`, but for when a node is attached to the root container. This is useful if attaching to the root has a slightly different implementation, or if the root container nodes are of a different type than the rest of the tree.\n\n#### `removeChild(parentInstance, child)`\n\nThis method should mutate the `parentInstance` to remove the `child` from the list of its children.\n\nReact will only call it for the top-level node that is being removed. It is expected that garbage collection would take care of the whole subtree. You are not expected to traverse the child tree in it.\n\n#### `removeChildFromContainer(container, child)`\n\nSame as `removeChild`, but for when a node is detached from the root container. This is useful if attaching to the root has a slightly different implementation, or if the root container nodes are of a different type than the rest of the tree.\n\n#### `resetTextContent(instance)`\n\nIf you returned `true` from `shouldSetTextContent` for the previous props, but returned `false` from `shouldSetTextContent` for the next props, React will call this method so that you can clear the text content you were managing manually. For example, in the DOM you could set `node.textContent = ''`.\n\nIf you never return `true` from `shouldSetTextContent`, you can leave it empty.\n\n#### `commitTextUpdate(textInstance, prevText, nextText)`\n\nThis method should mutate the `textInstance` and update its text content to `nextText`.\n\nHere, `textInstance` is a node created by `createTextInstance`.\n\n#### `commitMount(instance, type, props, internalHandle)`\n\nThis method is only called if you returned `true` from `finalizeInitialChildren` for this instance.\n\nIt lets you do some additional work after the node is actually attached to the tree on the screen for the first time. For example, the DOM renderer uses it to trigger focus on nodes with the `autoFocus` attribute.\n\nNote that `commitMount` does not mirror `removeChild` one to one because `removeChild` is only called for the top-level removed node. This is why ideally `commitMount` should not mutate any nodes other than the `instance` itself. For example, if it registers some events on some node above, it will be your responsibility to traverse the tree in `removeChild` and clean them up, which is not ideal.\n\nThe `internalHandle` data structure is meant to be opaque. If you bend the rules and rely on its internal fields, be aware that it may change significantly between versions. You're taking on additional maintenance risk by reading from it, and giving up all guarantees if you write something to it.\n\nIf you never return `true` from `finalizeInitialChildren`, you can leave it empty.\n\n#### `commitUpdate(instance, type, prevProps, nextProps, internalHandle)`\n\nThis method should mutate the `instance` to match `nextProps`.\n\nThe `internalHandle` data structure is meant to be opaque. If you bend the rules and rely on its internal fields, be aware that it may change significantly between versions. You're taking on additional maintenance risk by reading from it, and giving up all guarantees if you write something to it.\n\n#### `hideInstance(instance)`\n\nThis method should make the `instance` invisible without removing it from the tree. For example, it can apply visual styling to hide it. It is used by Suspense to hide the tree while the fallback is visible.\n\n#### `hideTextInstance(textInstance)`\n\nSame as `hideInstance`, but for nodes created by `createTextInstance`.\n\n#### `unhideInstance(instance, props)`\n\nThis method should make the `instance` visible, undoing what `hideInstance` did.\n\n#### `unhideTextInstance(textInstance, text)`\n\nSame as `unhideInstance`, but for nodes created by `createTextInstance`.\n\n#### `clearContainer(container)`\n\nThis method should mutate the `container` root node and remove all children from it.\n\n#### `maySuspendCommit(type, props)`\n\nThis method is called during render to determine if the Host Component type and props require some kind of loading process to complete before committing an update.\n\n#### `preloadInstance(type, props)`\n\nThis method may be called during render if the Host Component type and props might suspend a commit. It can be used to initiate any work that might shorten the duration of a suspended commit.\n\n#### `startSuspendingCommit()`\n\nThis method is called just before the commit phase. Use it to set up any necessary state while any Host Components that might suspend this commit are evaluated to determine if the commit must be suspended.\n\n#### `suspendInstance(type, props)`\n\nThis method is called after `startSuspendingCommit` for each Host Component that indicated it might suspend a commit.\n\n#### `waitForCommitToBeReady()`\n\nThis method is called after all `suspendInstance` calls are complete.\n\nReturn `null` if the commit can happen immediately.\n\nReturn `(initiateCommit: Function) => Function` if the commit must be suspended. The argument to this callback will initiate the commit when called. The return value is a cancellation function that the Reconciler can use to abort the commit.\n\n### Persistence Methods\n\nIf you use the persistent mode instead of the mutation mode, you would still need the \"Core Methods\". However, instead of the Mutation Methods above you will implement a different set of methods that performs cloning nodes and replacing them at the root level. You can find a list of them in the \"Persistence\" section [listed in this file](https://github.com/facebook/react/blob/main/packages/react-reconciler/src/forks/ReactFiberConfig.custom.js). File an issue if you need help.\n\n### Hydration Methods\n\nYou can optionally implement hydration to \"attach\" to the existing tree during the initial render instead of creating it from scratch. For example, the DOM renderer uses this to attach to an HTML markup.\n\nTo support hydration, you need to declare `supportsHydration: true` and then implement the methods in the \"Hydration\" section [listed in this file](https://github.com/facebook/react/blob/main/packages/react-reconciler/src/forks/ReactFiberConfig.custom.js). File an issue if you need help.\n"

If a work-in-progress render is discarded before finishing,\n// we create a new work-in-progress by cloning the current queue.\n//\n// Both queues share a persistent, singly-linked list structure. To schedule an\n// update, we append it to the end of both queues. Each queue maintains a\n// pointer to first update in the persistent list that hasn't been processed.\n// The work-in-progress pointer always has a position equal to or greater than\n// the current queue, since we always work on that one. The current queue's\n// pointer is only updated during the commit phase, when we swap in the\n// work-in-progress.\n//\n// For example:\n//\n//   Current pointer:           A - B - C - D - E - F\n//   Work-in-progress pointer:              D - E - F\n//                                          ^\n//                                          The work-in-progress queue has\n//                                          processed more updates than current.\n//\n// The reason we append to both queues is because otherwise we might drop\n// updates without ever processing them. For example, if we only add updates to\n// the work-in-progress queue, some updates could be lost whenever a work-in\n// -progress render restarts by cloning from current. Similarly, if we only add\n// updates to the current queue, the updates will be lost whenever an already\n// in-progress queue commits and swaps with the current queue. However, by\n// adding to both queues, we guarantee that the update will be part of the next\n// work-in-progress. (And because the work-in-progress queue becomes the\n// current queue once it commits, there's no danger of applying the same\n// update twice.)\n//\n// Prioritization\n// --------------\n//\n// Updates are not sorted by priority, but by insertion; new updates are always\n// appended to the end of the list.\n//\n// The priority is still important, though. When processing the update queue\n// during the render phase, only the updates with sufficient priority are\n// included in the result. If we skip an update because it has insufficient\n// priority, it remains in the queue to be processed later, during a lower\n// priority render. Crucially, all updates subsequent to a skipped update also\n// remain in the queue *regardless of their priority*. That means high priority\n// updates are sometimes processed twice, at two separate priorities. We also\n// keep track of a base state, that represents the state before the first\n// update in the queue is applied.\n//\n// For example:\n//\n//   Given a base state of '', and the following queue of updates\n//\n//     A1 - B2 - C1 - D2\n//\n//   where the number indicates the priority, and the update is applied to the\n//   previous state by appending a letter, React will process these updates as\n//   two separate renders, one per distinct priority level:\n//\n//   First render, at priority 1:\n//     Base state: ''\n//     Updates: [A1, C1]\n//     Result state: 'AC'\n//\n//   Second render, at priority 2:\n//     Base state: 'A'            <-  The base state does not include C1,\n//                                    because B2 was skipped.\n//     Updates: [B2, C1, D2]      <-  C1 was rebased on top of B2\n//     Result state: 'ABCD'\n//\n// Because we process updates in insertion order, and rebase high priority\n// updates when preceding updates are skipped, the final result is deterministic\n// regardless of priority. Intermediate state may vary according to system\n// resources, but the final state is always the same.\n\nimport type {Fiber, FiberRoot} from './ReactInternalTypes';\nimport type {Lanes, Lane} from './ReactFiberLane';\n\nimport {\n  NoLane,\n  NoLanes,\n  OffscreenLane,\n  isSubsetOfLanes,\n  mergeLanes,\n  removeLanes,\n  isTransitionLane,\n  intersectLanes,\n  markRootEntangled,\n} from './ReactFiberLane';\nimport {\n  enterDisallowedContextReadInDEV,\n  exitDisallowedContextReadInDEV,\n} from './ReactFiberNewContext';\nimport {\n  Callback,\n  Visibility,\n  ShouldCapture,\n  DidCapture,\n} from './ReactFiberFlags';\nimport getComponentNameFromFiber from './getComponentNameFromFiber';\n\nimport {StrictLegacyMode} from './ReactTypeOfMode';\nimport {\n  markSkippedUpdateLanes,\n  isUnsafeClassRenderPhaseUpdate,\n  getWorkInProgressRootRenderLanes,\n} from './ReactFiberWorkLoop';\nimport {\n  enqueueConcurrentClassUpdate,\n  unsafe_markUpdateLaneFromFiberToRoot,\n} from './ReactFiberConcurrentUpdates';\nimport {setIsStrictModeForDevtools} from './ReactFiberDevToolsHook';\n\nimport assign from 'shared/assign';\nimport {\n  peekEntangledActionLane,\n  peekEntangledActionThenable,\n} from './ReactFiberAsyncAction';\n\nexport type Update<State> = {\n  lane: Lane,\n\n  tag: 0 | 1 | 2 | 3,\n  payload: any,\n  callback: (() => mixed) | null,\n\n  next: Update<State> | null,\n};\n\nexport type SharedQueue<State> = {\n  pending: Update<State> | null,\n  lanes: Lanes,\n  hiddenCallbacks: Array<() => mixed> | null,\n};\n\nexport type UpdateQueue<State> = {\n  baseState: State,\n  firstBaseUpdate: Update<State> | null,\n  lastBaseUpdate: Update<State> | null,\n  shared: SharedQueue<State>,\n  callbacks: Array<() => mixed> | null,\n};\n\nexport const UpdateState = 0;\nexport const ReplaceState = 1;\nexport const ForceUpdate = 2;\nexport const CaptureUpdate = 3;\n\n// Global state that is reset at the beginning of calling `processUpdateQueue`.\n// It should only be read right after calling `processUpdateQueue`, via\n// `checkHasForceUpdateAfterProcessing`.\nlet hasForceUpdate = false;\n\nlet didWarnUpdateInsideUpdate;\nlet currentlyProcessingQueue: ?SharedQueue<$FlowFixMe>;\nexport let resetCurrentlyProcessingQueue: () => void;\nif (__DEV__) {\n  didWarnUpdateInsideUpdate = false;\n  currentlyProcessingQueue = null;\n  resetCurrentlyProcessingQueue = () => {\n    currentlyProcessingQueue = null;\n  };\n}\n\nexport function initializeUpdateQueue<State>(fiber: Fiber): void {\n  const queue: UpdateQueue<State> = {\n    baseState: fiber.memoizedState,\n    firstBaseUpdate: null,\n    lastBaseUpdate: null,\n    shared: {\n      pending: null,\n      lanes: NoLanes,\n      hiddenCallbacks: null,\n    },\n    callbacks: null,\n  };\n  fiber.updateQueue = queue;\n}\n\nexport function cloneUpdateQueue<State>(\n  current: Fiber,\n  workInProgress: Fiber,\n): void {\n  // Clone the update queue from current.

In the above example, you only need 3 bits to\n// represent slot 5. However, you need 5 bits to represent all the forks at\n// the current level, so we must account for the empty bits at the end.\n//\n// For this same reason, slots are 1-indexed instead of 0-indexed. Otherwise,\n// the zeroth id at a level would be indistinguishable from its parent.\n//\n// If a node has only one child, and does not materialize an id (i.e. does not\n// contain a useId hook), then we don't need to allocate any space in the\n// sequence. It's treated as a transparent indirection. For example, these two\n// trees produce the same ids:\n//\n// <>                          <>\n//   <Indirection>               <A />\n//     <A />                     <B />\n//   </Indirection>            </>\n//   <B />\n// </>\n//\n// However, we cannot skip any node that materializes an id. Otherwise, a parent\n// id that does not fork would be indistinguishable from its child id. For\n// example, this tree does not fork, but the parent and child must have\n// different ids.\n//\n// <Parent>\n//   <Child />\n// </Parent>\n//\n// To handle this scenario, every time we materialize an id, we allocate a\n// new level with a single slot. You can think of this as a fork with only one\n// prong, or an array of children with length 1.\n//\n// It's possible for the size of the sequence to exceed 32 bits, the max\n// size for bitwise operations. When this happens, we make more room by\n// converting the right part of the id to a string and storing it in an overflow\n// variable. We use a base 32 string representation, because 32 is the largest\n// power of 2 that is supported by toString(). We want the base to be large so\n// that the resulting ids are compact, and we want the base to be a power of 2\n// because every log2(base) bits corresponds to a single character, i.e. every\n// log2(32) = 5 bits.

Fast Refresh is a feature that lets you edit React components in a running application without losing their state. It is similar to an old feature known as \"hot reloading\", but Fast Refresh is more reliable and officially supported by React.\n\nThis package is primarily aimed at developers of bundler plugins. If you’re working on one, here is a [rough guide](https://github.com/facebook/react/issues/16604#issuecomment-528663101) for Fast Refresh integration using this package.\n"

    "path": "packages/react-server/README.md",
    "content": "# react-server\n\nThis is an experimental package for creating custom React streaming server renderers.\n\n**Its API is not as stable as that of React, React Native, or React DOM, and does not follow the common versioning scheme.**\n\n**Use it at your own risk.**\n\n## Usage\n\n`react-server` is a package implementing various Server Rendering capabilities. The two implementation are codenamed `Fizz` and `Flight`.\n\n`Fizz` is a renderer for Server Side Rendering React. The same code that runs in the client (browser or native) is run on the server to produce an initial view to send to the client before it has to download and run React and all the user code to produce that view on the client.\n\n`Flight` is a renderer for React Server Components. These are components that never run on a client. The output of a React Server Component render can be a React tree that can run on the client or be SSR'd using `Fizz`.\n\n## `Fizz` Usage\n\nThis part of the Readme is not fully developed yet\n\n## `Flight` Usage\n\nTo use `react-server` for React Server Components you must set up an implementation package alongside `react-client`. Use an existing implementation such as `react-server-dom-webpack` as a guide.\n\nYou might implement a render function like\n\n```js\nimport {\n  createRequest,\n  startWork,\n  startFlowing,\n  stopFlowing,\n  abort,\n} from 'react-server/src/ReactFlightServer'\n\nfunction render(\n  model: ReactClientValue,\n  clientManifest: ClientManifest,\n  options?: Options,\n): ReadableStream {\n  const request = createRequest(\n    model,\n    clientManifest,\n    options ? options.onError : undefined,\n    options ? options.identifierPrefix : undefined,\n    options ? options.temporaryReferences : undefined,\n    __DEV__ && options ? options.environmentName : undefined,\n    __DEV__ && options ? options.filterStackFrame : undefined,\n  );\n  const stream = new ReadableStream(\n    {\n      type: 'bytes',\n      start: (controller): ?Promise<void> => {\n        startWork(request);\n      },\n      pull: (controller): ?Promise<void> => {\n        startFlowing(request, controller);\n      },\n      cancel: (reason): ?Promise<void> => {\n        stopFlowing(request);\n        abort(request, reason);\n      },\n    },\n    {highWaterMark: 0},\n  );\n  return stream;\n}\n\n```\n\n### `Flight` Rendering\n\n`react-server` implements the React Server Components rendering implementation. React Server Components is in essence a general purpose serialization and deserialization capability with support for some built-in React primitives such as Suspense and Lazy.\n\nThe renderable type is a superset of `structuredClone()`. In addition to all the cloneable types `react-server` can render Symbols, Promises, Iterators and Iterables, async Iterators and Iterables.\n\nHere are some examples of what can be rendered\n```js\n// primitives\ncreateResponse(123, ...)\n\n// objects and Arrays\ncreateResponse({ messages: ['hello', 'react'] }, ...)\n\n// Maps, Sets, and more\ncreateResponse({ m: Map(['k', 'v'])}, ...)\n```\n\nAdditionally React built ins can be rendered including Function Components\n\nFunction Component are called and the return value can be any renderable type. Since `react-server` supports Promises, Function Components can be async functions.\n\nHere are some examples of what can be rendered\n```js\n\nasync function App({ children }) {\n  return children\n}\n\ncreateResponse(<App ><Children /></App>, ...)\n```\n\nFinally, There are two types of references in `react-server` that can be rendered\n\n#### Client References\nWhen a React Server Component framework bundles an application and encounters a `\"use client\"` directive it must resister exported members with `\"registerClientReference\"` which will encode the necessary information for `Flight` to interpret the export as a reference to be loaded on the client rather than a direct dependency on the Server module graph.\n\nWhen rendering a client reference `Flight` will encode necessary information in the serialized output to describe how to load the code which represents the client module.\n\nWhile it is common for client references to be components they can be any value.\n\n\n```js\n'use client'\n\nexport function alert(message) {\n  alert(message)\n}\n```\n\n```js\n'use client'\n\nexport function ClientComp({ onClick, message }) {\n  return <button onClick={onClick}>Alert</button>\n}\n```\n\n```js\n\n// client references don't have to just be components, anything can be \n// a reference, in this case we're importing a function that will be\n// passed to the ClientComp component\nimport { alert } from '...'\nimport { ClientComp } from '...'\n\nasync function App({ children }) {\n  return children\n}\n\ncreateResponse(\n  <App >\n    <ClientComp onClick={alert} message={\"hello world\"} />\n  </App>,\n...)\n```\n\n#### Server References\nSimilarly When a React Server Component framework bundles an application and encounters a `\"use server\"` directive in a file or in a function body, including closures, it must implement that function as as a server entrypoint that can be called from the client. To make `Flight` aware that a function is a Server Reference the function should be registered with `registerServerReference()`.\n\n```js\n\nasync function logOnServer(message) {\n  \"use server\"\n  console.log(message)\n}\n\nasync function App({ children }) {\n  // logOnServer can be used in a Server Component\n  logOnServer('used from server')\n  return children\n}\n\ncreateResponse(\n  <App >\n    <ClientComp onClick={logOnServer} message={\"used from client\"} />\n  </App>,\n...)\n```\n\n### `Flight` Prerendering\n\nWhen rendering with `react-server` there are two broad contexts when this might happen. Realtime when responding to a user request and ahead of time when prerendering a page that can later be used more than once.\n\nWhile the core rendering implementation is the same in both cases there are subtle differences we can adopt that take advantage of the context. For instance while rendering in response to a real user request we want to stream eagerly if the consumer is requesting information. This allows us to stream content to the consumer as it becomes available but might have implications for the stability of the serialized format. When prerendering we assume there is not urgency to producing a partial result as quickly as possible so we can alter the internal implementation take advantage of this. To implement a prerender API use `createPrerenderRequest` in place of `createRequest`.\n\nOne key semantic change prerendering has with rendering is how errors are handled. When rendering an error is embedded into the output and must be handled by the consumer such as an SSR render or on the client. However with prerendering there is an expectation that if the prerender errors then the entire prerender will be discarded or it will be used but the consumer will attempt to recover that error by asking for a dynamic render. This is analogous to how errors during SSR aren't immediately handled they are actually encoded as requests for client recovery. The error only is observed if the retry on the client actually fails. To account for this prerenders simply omit parts of the model that errored. you can use the `onError` argument in `createPrerenderRequest` to observe if an error occurred and users of your `prerender` implementation can choose whether to abandon the prerender or implement dynamic recovery when an error occurs.\n\nExisting implementations only return the stream containing the output of the prerender once it has completed. In the future we may introduce a `resume` API similar to the one that exists for `Fizz`. In anticipation of such an API it is expected that implementations of `prerender` return the type `Promise<{ prelude: <Host Appropriate Stream Type> }>`\n\n```js\nfunction prerender(\n  model: ReactClientValue,\n  clientManifest: ClientManifest,\n  options?: Options,\n): Promise<StaticResult> {\n  return new Promise((resolve, reject) => {\n    const onFatalError = reject;\n    function onAllReady() {\n      const stream = new ReadableStream(\n        {\n          type: 'bytes',\n          start: (controller): ?Promise<void> => {\n            startWork(request);\n          },\n          pull: (controller): ?Promise<void> => {\n            startFlowing(request, controller);\n          },\n          cancel: (reason): ?Promise<void> => {\n            stopFlowing(request);\n            abort(request, reason);\n          },\n        },\n        // $FlowFixMe[prop-missing] size() methods are not allowed on byte streams.\n        {highWaterMark: 0},\n      );\n      resolve({prelude: stream});\n    }\n    const request = createPrerenderRequest(\n      model,\n      clientManifest,\n      onAllReady,\n      onFatalError,\n      options ? options.onError : undefined,\n      options ? options.identifierPrefix : undefined,\n      options ? options.temporaryReferences : undefined,\n      __DEV__ && options ? options.environmentName : undefined,\n      __DEV__ && options ? options.filterStackFrame : undefined,\n    );\n    startWork(request);\n  });\n}\n```\n\n## `Flight` Reference (Incomplete)\n\n### `createRequest(model, bundlerConfig, ...options): Request`\n\nThe signature of this method changes as we evolve the project so this Readme will omit the specific signature but generally this function will produce a Request that represents the rendering of some React application (the model) along with implementation specific bundler configuration. Typically this configuration will tell the `Flight` implementation how to encode Client References in the serialized output\n\nThe `RequestInstance` represents the render.\n\nRendering does not actually begin until you call `startWork`\n\n### `createPrerenderRequest(model, bundlerConfig, ...options): Request`\n\nThis is similar to `createRequest` but it alters some internal semantics for how errors and aborts are treated. It returns the same type as `createRequest`.\n\n### `startWork(request: Request): void`\n\nWhen passed a request this will initiate the actual render. It will continue until it completes\n\n### `startFlowing(request: Request, destination: Destination): void`\n\na destination is whatever the implementation wants to use for storing the output of the render. In existing implementations it is either a Node stream or a Web stream. When you call `startFlowing` the request will write to the destination continuously whenever more chunks are unblocked, say after an async function has resolved and there is something new to serialize. You can implement streaming backpressure using `stopFlowing()`\n\n### `stopFlowing(request: Request): void`\n\nIf you need to pause or permanently end the writing of any additional serialized output for this request you can call `stopFlowing(request)`. You may start flowing again after you've stopped. This is how you would implement backpressure support for streams for instance. It's important to note that stopping flowing is not going to stop rendering. If you want rendering to stop you must `abort` the request.\n\n### `abort(request: Request): void`\n\nIf you want to stop rendering you can abort the request with `abort(request)`. This will cause all incomplete work to be abandoned. If the request was created with `createRequest` the abort will encode errors into any unfinished slots in the serialization. If the request was created with `createPrerenderRequest` the abort will omit anything in the places that are unfinished leaving the serialized model in an incomplete state.\n"

In the above example, you only need 3 bits to\n// represent slot 5. However, you need 5 bits to represent all the forks at\n// the current level, so we must account for the empty bits at the end.\n//\n// For this same reason, slots are 1-indexed instead of 0-indexed. Otherwise,\n// the zeroth id at a level would be indistinguishable from its parent.\n//\n// If a node has only one child, and does not materialize an id (i.e. does not\n// contain a useId hook), then we don't need to allocate any space in the\n// sequence. It's treated as a transparent indirection. For example, these two\n// trees produce the same ids:\n//\n// <>                          <>\n//   <Indirection>               <A />\n//     <A />                     <B />\n//   </Indirection>            </>\n//   <B />\n// </>\n//\n// However, we cannot skip any node that materializes an id.

As of React 19, you will see a console warning when invoking `ReactTestRenderer.create()`.\n\n### React Testing\n\nThis library creates a contrived environment and its APIs encourage introspection on React's internals, which may change without notice causing broken tests. It is instead recommended to use browser-based environments such as jsdom and standard DOM APIs for your assertions.\n\nThe React team recommends [`@testing-library/react`](https://testing-library.com/docs/react-testing-library/intro) as a modern alternative that uses standard APIs, avoids internals, and [promotes best practices](https://testing-library.com/docs/guiding-principles).\n\n### React Native Testing\n\nThe React team recommends @testing-library/react-native as a replacement for `react-test-renderer` for native integration tests. This React Native testing-library variant follows the same API design as described above and promotes better testing patterns.\n\n## Documentation\n\nThis package provides an experimental React renderer that can be used to render React components to pure JavaScript objects, without depending on the DOM or a native mobile environment.\n\nEssentially, this package makes it easy to grab a snapshot of the \"DOM tree\" rendered by a React DOM or React Native component without using a browser or jsdom.\n\nDocumentation: [https://reactjs.org/docs/test-renderer.html](https://reactjs.org/docs/test-renderer.html)\n\nUsage:\n\n```jsx\nconst ReactTestRenderer = require('react-test-renderer');\n\nconst renderer = ReactTestRenderer.create(\n  <Link page=\"https://www.facebook.com/\">Facebook</Link>\n);\n\nconsole.log(renderer.toJSON());\n// { type: 'a',\n//   props: { href: 'https://www.facebook.com/' },\n//   children: [ 'Facebook' ] }\n```\n\nYou can also use Jest's snapshot testing feature to automatically save a copy of the JSON tree to a file and check in your tests that it hasn't changed: https://jestjs.io/blog/2016/07/27/jest-14.html.\n"

    "content": "# use-subscription\n\nReact Hook for subscribing to external data sources.\n\n**You may now migrate to [`use-sync-external-store`](https://www.npmjs.com/package/use-sync-external-store) directly instead, which has the same API as [`React.useSyncExternalStore`](https://react.dev/reference/react/useSyncExternalStore). The `use-subscription` package is now a thin wrapper over `use-sync-external-store` and will not be updated further.**\n\n# Installation\n\n```sh\n# Yarn\nyarn add use-subscription\n\n# NPM\nnpm install use-subscription\n```\n\n# Usage\n\nTo configure a subscription, you must provide two methods: `getCurrentValue` and `subscribe`.\n\nIn order to avoid removing and re-adding subscriptions each time this hook is called, the parameters passed to this hook should be memoized. This can be done by wrapping the entire subscription with `useMemo()`, or by wrapping the individual callbacks with `useCallback()`.\n\n## Subscribing to event dispatchers\n\nBelow is an example showing how `use-subscription` can be used to subscribe to event dispatchers such as DOM elements.\n\n```js\nimport React, { useMemo } from \"react\";\nimport { useSubscription } from \"use-subscription\";\n\n// In this example, \"input\" is an event dispatcher (e.g. an HTMLInputElement)\n// but it could be anything that emits an event and has a readable current value.\nfunction Example({ input }) {\n\n  // Memoize to avoid removing and re-adding subscriptions each time this hook is called.\n  const subscription = useMemo(\n    () => ({\n      getCurrentValue: () => input.value,\n      subscribe: callback => {\n        input.addEventListener(\"change\", callback);\n        return () => input.removeEventListener(\"change\", callback);\n      }\n    }),\n\n    // Re-subscribe any time our input changes\n    // (e.g. we get a new HTMLInputElement prop to subscribe to)\n    [input]\n  );\n\n  // The value returned by this hook reflects the input's current value.\n  // Our component will automatically be re-rendered when that value changes.\n  const value = useSubscription(subscription);\n\n  // Your rendered output goes here ...\n}\n```\n\n## Subscribing to observables\n\nBelow are examples showing how `use-subscription` can be used to subscribe to certain types of observables (e.g. RxJS `BehaviorSubject` and `ReplaySubject`).\n\n**Note** that it is not possible to support all observable types (e.g. RxJS `Subject` or `Observable`) because some provide no way to read the \"current\" value after it has been emitted.\n\n### `BehaviorSubject`\n```js\nconst subscription = useMemo(\n  () => ({\n    getCurrentValue: () => behaviorSubject.getValue(),\n    subscribe: callback => {\n      const subscription = behaviorSubject.subscribe(callback);\n      return () => subscription.unsubscribe();\n    }\n  }),\n\n  // Re-subscribe any time the behaviorSubject changes\n  [behaviorSubject]\n);\n\nconst value = useSubscription(subscription);\n```\n\n### `ReplaySubject`\n```js\nconst subscription = useMemo(\n  () => ({\n    getCurrentValue: () => {\n      let currentValue;\n      // ReplaySubject does not have a sync data getter,\n      // So we need to temporarily subscribe to retrieve the most recent value.\n      replaySubject\n        .subscribe(value => {\n          currentValue = value;\n        })\n        .unsubscribe();\n      return currentValue;\n    },\n    subscribe: callback => {\n      const subscription = replaySubject.subscribe(callback);\n      return () => subscription.unsubscribe();\n    }\n  }),\n\n  // Re-subscribe any time the replaySubject changes\n  [replaySubject]\n);\n\nconst value = useSubscription(subscription);\n```\n"

A local and remote build will occur on React and ReactDOM UMD bundles, both local and remote repos will be run against all benchmarks.\n\nThe second command will run all benchmarks but skip the build process. This is useful for when doing local performance tweaking and the remote repo has already had its bundles built. Both local and remote repos will be run against all benchmarks with this command too.\n\nThe other commands are as follows:\n\n```bash\n# will compare local repo vs remote merge base repo\nyarn start\n\n# will compare local repo vs remote merge base repo\n# this can significantly improve bench times due to no build\nyarn start --skip-build\n\n# will only build and run local repo against benchmarks (no remote values will be shown)\nyarn start --local\n\n# will only build and run remote merge base repo against benchmarks (no local values will be shown)\nyarn start --remote\n\n# will only build and run remote main repo against benchmarks\nyarn start --remote=main\n\n# same as \"yarn start\"\nyarn start --remote --local\n\n# runs benchmarks with Chrome in headless mode\nyarn start --headless\n\n# runs only specific string matching benchmarks\nyarn start --benchmark=hacker\n```\n"

    "content": "The error code system substitutes React's error messages with error IDs to\nprovide a better debugging support in production. Check out the blog post\n[here](https://reactjs.org/blog/2016/07/11/introducing-reacts-error-code-system.html).\n\n- [`codes.json`](https://github.com/facebook/react/blob/main/scripts/error-codes/codes.json)\n  contains the mapping from IDs to error messages. This file is generated by the\n  Gulp plugin and is used by both the Babel plugin and the error decoder page in\n  our documentation. This file is append-only, which means an existing code in\n  the file will never be changed/removed.\n- [`extract-errors.js`](https://github.com/facebook/react/blob/main/scripts/error-codes/extract-errors.js)\n  is an node script that traverses our codebase and updates `codes.json`. You\n  can test it by running `yarn extract-errors`. It works by crawling the build\n  artifacts directory, so you need to have either run the build script or\n  downloaded pre-built artifacts (e.g. with `yarn download build`). It works\n  with partial builds, too.\n- [`transform-error-messages`](https://github.com/facebook/react/blob/main/scripts/error-codes/transform-error-messages.js)\n  is a Babel pass that rewrites error messages to IDs for a production\n  (minified) build.\n"

Also, error-handling code isn't usually perf-critical.\n//\n// Non-production codepaths (tests, devtools extension, build tools, etc.)\n// should use `String(value)` because it will never crash and the (small) perf\n// difference doesn't matter enough for non-prod use cases.\n//\n// This rule assists enforcing these guidelines:\n// * `'' + value` is flagged with a message to remind developers to add a DEV\n//   check from shared/CheckStringCoercion.js to make sure that the user gets a\n//   clear error message in DEV is the coercion will throw. These checks are not\n//   needed if throwing is not possible, e.g. if the value is already known to\n//   be a string or number.\n// * `String(value)` is flagged only if the `isProductionUserAppCode` option\n//   is set. Set this option for prod code files, and don't set it for non-prod\n//   files.\n\nconst ignoreKeys = [\n  'range',\n  'raw',\n  'parent',\n  'loc',\n  'start',\n  'end',\n  '_babelType',\n  'leadingComments',\n  'trailingComments',\n];\nfunction astReplacer(key, value) {\n  return ignoreKeys.includes(key) ? undefined : value;\n}\n\n/**\n * Simplistic comparison between AST node.

    "content": "# React Release Scripts\n\nThis document describes how to prepare and publish a release manually, using the command line.\n\nHowever, most of our releases are actually *prereleases* that get continuously shipped via CI. Our automated prerelease channels are preferred whenever possible, because if they accidentally break, it won't affect production users.\n\nBefore proceeding, consider your motivation:\n\n- **\"I want to share experimental features with collaborators.\"** After your code lands in GitHub (behind an experimental feature flag), it will be automatically published via CI within the next weekday. So usually, all you have to do is wait.\n- **\"But I want to publish it now!\"** You can [trigger the CI job to run automatically](#trigger-an-automated-prerelease).\n- **\"I want to publish a stable release with a real version number\"** Refer to the [\"Publishing a Stable Release\"](#publishing-a-stable-release) section. If this is your first time running a stable release, consult with another team member before proceeding.\n- **\"I have some special use case that's not explicitly mentioned here.\"** Read the rest of this document, and consult with another team member before proceeding.\n\n# Process\n\nIf this is your first time running the release scripts, go to the `scripts/release` directory and run `yarn` to install the dependencies.\n\nThe release process consists of several phases, each one represented by one of the scripts below.\n\nA typical release cycle goes like this:\n1. When a commit is pushed to the React repo, [GitHub Actions](https://github.com/facebook/react/actions) will build all release bundles and run unit tests against both the source code and the built bundles.\n2. Each weekday, an automated CI cron job publishes prereleases to the `next` and `experimental` channels, from tip of the main branch.\n   1. You can also [trigger an automated prerelease via the GitHub UI](#trigger-an-automated-prerelease), instead of waiting until the next time the cron job runs.\n   2. For advanced cases, you can [**manually prepare and publish to the `next` channel**](#publishing-release) using the [`prepare-release-from-ci`](#prepare-release-from-ci) and [`publish`](#publish) scripts; or to the [**`experimental` channel**](#publishing-an-experimental-release) using the same scripts (but different build artifacts).\n3. Finally, a \"next\" release can be [**promoted to stable**](#publishing-a-stable-release)<sup>1</sup> using the [`prepare-release-from-npm`](#prepare-release-from-npm) and [`publish`](#publish) scripts. (This process is always manual.)\n\nThe high level process of creating releases is [documented below](#process). Individual scripts are documented as well:\n* [`build-release-locally`](#build-release-locally): Build a release locally from the checked out source code.\n* [`prepare-release-from-ci`](#prepare-release-from-ci): Download a pre-built release from CI.\n* [`prepare-release-from-npm`](#prepare-release-from-npm): Prepare an NPM \"next\" release to be published as a \"stable\" release.\n* [`publish`](#publish): Publish the downloaded (or prepared) release to NPM.\n\n<sup>1. [**Creating a patch release**](#creating-a-patch-release) has a slightly different process than a major/minor release.</sup>\n\n## Trigger an Automated Prerelease\n\nIf your code lands in the main branch, it will be automatically published to the prerelease channels within the next weekday. However, if you want to immediately publish a prerelease, you can trigger the job to run immediately via the GitHub UI:\n\n1. Wait for the commit you want to release to finish its [(Runtime) Build and Test workflow](https://github.com/facebook/react/actions/workflows/runtime_build_and_test.yml), as the prerelease script needs to download the build from that workflow.\n2. Copy the full git sha of whichever commit you are trying to release\n3. Go to https://github.com/facebook/react/actions/workflows/runtime_prereleases_manual.yml\n4. Paste the git sha into the \"Run workflow\" dropdown\n5. Let the job finish and it will be released on npm\n\nThis will grab the specified revision on the main branch and publish it to the Next and Experimental channels.\n## Publishing Without Tags\n\nThe sections below include meaningful `--tags` in the instructions. However, keep in mind that **the `--tags` arguments is optional**, and you can omit it if you don't want to tag the release on npm at all. This can be useful when preparing breaking changes.\n\n## Publishing Next\n\n\"Next\" builds are meant to be lightweight and published often. In most cases, they can be published using artifacts built by Circle CI.\n\nTo prepare a build for a particular commit:\n1. Choose a commit from [the commit log](https://github.com/facebook/react/commits/main).\n2. Copy the SHA (by clicking the 📋 button)\n5. Run the [`prepare-release-from-ci`](#prepare-release-from-ci) script with the SHA <sup>1</sup> you found:\n```sh\nscripts/release/prepare-release-from-ci.js -r stable --commit=0e526bc\n```\n\nOnce the build has been checked out and tested locally, you're ready to publish it:\n```sh\nscripts/release/publish.js --tags next\n```\n\n<sup>1: You can omit the `commit` param if you just want to release the latest commit as to \"next\".</sup>\n\n## Publishing an Experimental Release\n\nExperimental releases are special because they have additional features turned on.\n\nThe steps for publishing an experimental release are almost the same as for publishing a \"next\" release except for the release channel (`-r`) flag.\n\n```sh\nscripts/release/prepare-release-from-ci.js -r experimental --commit=0e526bc\n```\n\nOnce the build has been checked out and tested locally, you're ready to publish it. When publishing an experimental release, use the `experimental` tag:\n\n```sh\nscripts/release/publish.js --tags experimental\n```\n\n## Publishing a Stable Release\n\nStable releases should always be created from the \"next\" channel. This encourages better testing of the actual release artifacts and reduces the chance of unintended changes accidentally being included in a stable release.\n\nTo prepare a stable release, choose a \"next\" version and run the [`prepare-release-from-npm`](#prepare-release-from-npm) script <sup>1</sup>:\n\n```sh\nscripts/release/prepare-release-from-npm.js --version=0.0.0-241c4467e-20200129\n```\n\nThis script will prompt you to select stable version numbers for each of the packages. It will update the package JSON versions (and dependencies) based on the numbers you select.\n\nOnce this step is complete, you're ready to publish the release:\n\n```sh\nscripts/release/publish.js --tags latest\n\n# Or, if you want to bump \"next\" as well:\nscripts/release/publish.js --tags latest next\n```\n\nAfter successfully publishing the release, follow the on-screen instructions to ensure that all of the appropriate post-release steps are executed.\n\n<sup>1: You can omit the `version` param if you just want to promote the latest \"next\" candidate to stable.</sup>\n\n## Creating a Patch Release\n\nPatch releases should always be created by branching from a previous release. This reduces the likelihood of unstable changes being accidentally included in the release.\n\nBegin by creating a branch from the previous git tag<sup>1</sup>:\n\n```sh\ngit checkout -b 16.8.3 v16.8.2\n```\n\nNext cherry pick any changes from main that you want to include in the release:\n\n```sh\ngit cherry-pick <commit-hash>\n```\n\nOnce you have cherry picked all of the commits you want to include in the release, push your feature branch and create a Pull Request (so that Circle CI will create a build):\n\n```sh\ngit push origin 16.8.3\n```\n\nOnce CI is complete, follow the regular [**next**](#publishing-release) and [**promote to stable**](#publishing-a-stable-release) processes.\n\n<sup>1: The `build-info.json` artifact can also be used to identify the appropriate commit (e.g. [unpkg.com/react@16.8.3/build-info.json](https://unpkg.com/react@16.8.3/build-info.json) shows us that react version 16.8.3 was created from commit [`29b7b775f`](https://github.com/facebook/react/commit/29b7b775f)).</sup>\n\n# Scripts\n\n## `build-release-locally`\nCreates a \"next\" build from the current (local) Git revision.\n\n**This script is an escape hatch.** It allows a release to be created without pushing a commit to be verified by Circle CI. **It does not run any automated unit tests.** Testing is solely the responsibility of the release engineer.\n\nNote that this script git-archives the React repo (at the current revision) to a temporary directory before building, so **uncommitted changes are not included in the build**.\n\n#### Example usage\nTo create a build from the current branch and revision:\n```sh\nscripts/release/build-release-locally.js\n```\n\n## `prepare-release-from-ci`\nDownloads build artifacts from Circle CI in preparation to be published to NPM as either a \"next\" or \"experimental\" release.\n\nAll artifacts built by Circle CI have already been unit-tested (both source and bundles) but these candidates should **always be manually tested** before being published. Upon completion, this script prints manual testing instructions.\n\n#### Example usage\nTo prepare the artifacts created by Circle CI for commit [0e526bc](https://github.com/facebook/react/commit/0e526bc) you would run:\n```sh\nscripts/release/prepare-release-from-ci.js --commit=0e526bc -r stable\n```\n\n## `prepare-release-from-npm`\nChecks out a \"next\" release from NPM and prepares it to be published as a stable release.\n\nThis script prompts for new (stable) release versions for each public package and updates the package contents (both `package.json` and inline version numbers) to match. It also updates inter-package dependencies to account for the new versions.\n\n\"Next\" releases have already been tested but it is still a good idea to **manually test and verify a release** before publishing to ensure that e.g. version numbers are correct. Upon completion, this script prints manual testing instructions.\n\n#### Example usage\nTo promote the \"next\" release `0.0.0-241c4467e-20200129` (aka commit [241c4467e](https://github.com/facebook/react/commit/241c4467e)) to stable:\n```sh\nscripts/release/prepare-release-from-npm.js --version=0.0.0-241c4467e-20200129\n```\n\n## `publish`\nPublishes the current contents of `build/node_modules` to NPM.\n\nThis script publishes each public package to NPM and updates the specified tag(s) to match. **It does not test or verify the local package contents before publishing**. This should be done by the release engineer prior to running the script.\n\nUpon completion, this script provides instructions for tagging the Git commit that the package was created from and updating the release CHANGELOG.\n\n**Specify a `--dry` flag when running this script if you want to skip the NPM-publish step.** In this event, the script will print the NPM commands but it will not actually run them.\n\n#### Example usage\nTo publish a release to NPM as both `next` and `latest`:\n```sh\nscripts/release/publish.js --tags latest next\n```\n"
