Then from the root of Dioxus you can type `Ctrl + Shift + P`, then choose `Dev Containers: Rebuild and Reopen in Devcontainer`.\n\n### Codespaces\n\n[Codespaces Setup](https://docs.github.com/en/codespaces/developing-in-codespaces/creating-a-codespace-for-a-repository#creating-a-codespace-for-a-repository)\n\n### Playwright Tests\nThe dev container comes with Playwright dependencies pre-installed.\nYou can run the tests located in `packages/playwright-tests` by using the VSCode extension or by executing commands such as:\n\n```bash\n# Run all tests\nnpx playwright test\n\n# Run tests using the UI mode\nnpx playwright test --ui-host=0.0.0.0\n```\n\n## Troubleshooting\n\nIf having difficulty commiting with github, and you use ssh or gpg keys, you may need to ensure that the keys are being shared properly between your host and VSCode.\n\nThough VSCode does a pretty good job sharing credentials between host and devcontainer, to save some time you can always just reopen the container locally to commit with `Ctrl + Shift + P`, then choose `Dev Containers: Reopen Folder Locally`\n" }, { "path": ".devcontainer/devcontainer.json", "content": "{\n \"name\": \"dioxus\",\n \"remoteUser\": \"vscode\",\n \"build\": {\n \"dockerfile\": \"./Dockerfile\",\n \"context\": \".\"\n },\n \"features\": {\n \"ghcr.io/devcontainers/features/common-utils:2\": {\n \"installZsh\": \"true\",\n \"username\": \"vscode\",\n \"uid\": \"1000\",\n \"gid\": \"1000\",\n \"upgradePackages\": \"true\"\n }\n },\n \"containerEnv\": {\n \"RUST_LOG\": \"INFO\"\n },\n \"customizations\": {\n \"vscode\": {\n \"settings\": {\n \"files.watcherExclude\": {\n \"**/target/**\": true\n },\n \"[rust]\": {\n \"editor.formatOnSave\": true\n }\n },\n \"extensions\": [\n \"rust-lang.rust-analyzer\",\n \"tamasfe.even-better-toml\",\n \"fill-labs.dependi\",\n \"ms-playwright.playwright\"\n ]\n }\n }\n}" }, { "path": ".github/CODEOWNERS", "content": "# borrowed from tauri -

It compiles to web (WASM), desktop (webview), mobile (iOS/Android), and native (GPU-rendered).\n\n## Quick Overview\n\n- **Language**: Rust (stable toolchain)\n- **UI Model**: React-like with VirtualDOM, components, hooks, signals\n- **Syntax**: JSX-like `rsx!` macro for declaring UI\n- **Platforms**: Web, Desktop (Windows/macOS/Linux), Mobile, Native, LiveView (server-rendered)\n\n## Workspace Structure\n\n```\npackages/\nā”œā”€ā”€ dioxus/ # Main re-export crate users depend on\nā”œā”€ā”€ core/ # VirtualDOM, components, diffing, scheduling\nā”œā”€ā”€ rsx/ # RSX macro parsing and code generation\nā”œā”€ā”€ rsx-hotreload/ # Template diffing for hot-reload\nā”œā”€ā”€ signals/ # Reactive state (Signal, Memo, Store)\nā”œā”€ā”€ hooks/ # Built-in hooks (use_signal, use_effect, etc.)\nā”œā”€ā”€ router/ # Type-safe routing with #[derive(Routable)]\nā”œā”€ā”€ fullstack/ # SSR, hydration, #[server] functions\nā”œā”€ā”€ cli/ # `dx` build tool, dev server, bundling\nā”œā”€ā”€ web/ # WASM renderer\nā”œā”€ā”€ desktop/ # Wry/Tao webview renderer\nā”œā”€ā”€ native/ # Blitz/Vello GPU renderer\nā”œā”€ā”€ liveview/ # WebSocket streaming renderer\nā”œā”€ā”€ manganis/ # asset!() macro for compile-time assets\nā”œā”€ā”€ subsecond/ # Hot-patching system (jump table indirection)\nā”œā”€ā”€ devtools/ # Dev server communication protocol\nā”œā”€ā”€ interpreter/ # Sledgehammer JS for DOM mutations\nā””ā”€ā”€ wasm-split/ # WASM code splitting\n```\n\n## Architecture Documentation\n\nFor deeper understanding, see `notes/architecture/`:\n\n| When working on... | Read... |\n| ------------------------------------------ | ------------------ |\n| VirtualDOM, components, diffing, events | `01-CORE.md` |\n| CLI, build system, bundling, dev server | `02-CLI.md` |\n| RSX macro, parsing, formatting | `03-RSX.md` |\n| Signals, state management, reactivity | `04-SIGNALS.md` |\n| Server functions, SSR, hydration | `05-FULLSTACK.md` |\n| Web/desktop/native/liveview renderers | `06-RENDERERS.md` |\n| Hot-reload, hot-patching, devtools | `07-HOTRELOAD.md` |\n| Asset macro, manganis, const serialization | `08-ASSETS.md` |\n| Router, navigation, nested routes | `09-ROUTER.md` |\n| WASM code splitting | `10-WASM-SPLIT.md` |\n\n## Key Concepts\n\n- **VirtualDOM**: Tree of `VNode` with templates, dynamic nodes, and attributes\n- **Signals**: Copy-able reactive primitives via generational-box (generation-based validity)\n- **WriteMutations**: Trait that renderers implement to apply DOM changes\n- **RSX**: Proc macro that compiles JSX-like syntax to `VNode` construction\n- **Server Functions**: `#[server]` macro generates client RPC stubs and server handlers\n- **Subsecond**: Hot-patches Rust code via jump table indirection (no memory modification)\n- **Manganis**: `asset!(\"/main.css\")` macro for including assets by embedding data via linker symbols\n\n## Common Patterns\n\n**Component definition**:\n```rust\n#[component]\nfn MyComponent(name: String) -> Element {\n let mut count = use_signal(|| 0);\n rsx! {\n button { onclick: move |_| count += 1, \"{name}: {count}\" }\n }\n}\n```\n\n## Notes for Agents\n\n1. The `dioxus` crate re-exports from other crates - most implementation is in `packages/core`, `packages/signals`, etc.\n2. RSX macro expansion happens in `packages/rsx` - look there for syntax questions\n3. Each renderer implements `WriteMutations` differently - see `06-RENDERERS.md`\n4. Hot-reload has two systems: RSX template diffing (fast) and Subsecond code patching (full Rust)\n5. Assets use link sections and binary patching - the `asset!()` macro creates symbols the CLI processes\n" }, { "path": "Cargo.toml", "content": "[workspace]\nresolver = \"2\"\nmembers = [\n

\n āœØ Dioxus 0.7 is out!!! āœØ\n

\n
\n\nBuild for web, desktop, and mobile, and more with a single codebase. Zero-config setup, integrated hot-reloading, and signals-based state management. Add backend functionality with Server Functions and bundle with our CLI.\n\n```rust\nfn app() -> Element {\n let mut count = use_signal(|| 0);\n\n rsx! {\n h1 { \"High-Five counter: {count}\" }\n button { onclick: move |_| count += 1, \"Up high!\" }\n button { onclick: move |_| count -= 1, \"Down low!\" }\n }\n}\n```\n\n## ā­ļø Unique features:\n\n- Cross-platform apps in three lines of code (web, desktop, mobile, server, and more)\n- [Ergonomic state management](https://dioxuslabs.com/blog/release-050) combines the best of React, Solid, and Svelte\n- Built-in featureful, type-safe, fullstack web framework\n- Integrated bundler for deploying to the web, macOS, Linux, and Windows\n- Subsecond Rust hot-patching and asset hot-reloading\n- And more! [Take a tour of Dioxus](https://dioxuslabs.com/learn/0.7/).\n\n## Instant hot-reloading\n\nWith one command, `dx serve` and your app is running. Edit your markup, styles, and see changes in milliseconds. Use our experimental `dx serve --hotpatch` to update Rust code in real time.\n\n
\n \n \n \n
\n\n## Build Beautiful Apps\n\nDioxus apps are styled with HTML and CSS. Use the built-in TailwindCSS support or load your favorite CSS library. Easily call into native code (objective-c, JNI, Web-Sys) for a perfect native touch.\n\n
\n \n
\n\n\n\n## Truly fullstack applications\n\nDioxus deeply integrates with [axum](https://github.com/tokio-rs/axum) to provide powerful fullstack capabilities for both clients and servers. Pick from a wide array of built-in batteries like WebSockets, SSE, Streaming, File Upload/Download, Server-Side-Rendering, Forms, Middleware, and Hot-Reload, or go fully custom and integrate your existing axum backend.\n\n
\n \n
\n\n## Experimental Native Renderer\n\nRender using web-sys, webview, server-side-rendering, liveview, or even with our experimental WGPU-based renderer. Embed Dioxus in Bevy, WGPU, or even run on embedded Linux!\n\n
\n \n
\n\n\n## First-party primitive components\n\nGet started quickly with a complete set of primitives modeled after shadcn/ui and Radix-Primitives.\n\n
\n \n
\n\n## First-class Android and iOS support\n\nDioxus is the fastest way to build native mobile apps with Rust. Simply run `dx serve --platform android` and your app is running in an emulator or on device in seconds. Call directly into JNI and Native APIs.\n\n
\n \n
\n\n\n\n## Bundle for web, desktop, and mobile\n\nSimply run `dx bundle` and your app will be built and bundled with maximization optimizations. On the web, take advantage of [`.avif` generation, `.wasm` compression, minification](https://dioxuslabs.com/learn/0.7/tutorial/assets), and more. Build WebApps weighing [less than 50kb](https://github.com/ealmloff/tiny-dioxus/) and desktop/mobile apps less than 5mb.\n\n
\n \n
\n\n\n## Fantastic documentation\n\nWe've put a ton of effort into building clean, readable, and comprehensive documentation. All html elements and listeners are documented with MDN docs, and our Docs runs continuous integration with Dioxus itself to ensure that the docs are always up to date. Check out the [Dioxus website](https://dioxuslabs.com/learn/0.7/) for guides, references, recipes, and more. Fun fact: we use the Dioxus website as a testbed for new Dioxus features - [check it out!](https://github.com/dioxusLabs/docsite)\n\n
\n \n
\n\n\n## Modular and Customizable\n\nBuild your own renderer. Use our modular components like RSX, VirtualDom, Blitz, Taffy, and Subsecond.\n\n## Community\n\nDioxus is a community-driven project, with a very active [Discord](https://discord.gg/XgGxMSkvUM) and [GitHub](https://github.com/DioxusLabs/dioxus/issues) community. We're always looking for help, and we're happy to answer questions and help you get started. [Our SDK](https://github.com/DioxusLabs/dioxus-std) is community-run and we even have a [GitHub organization](https://github.com/dioxus-community/) for the best Dioxus crates that receive free upgrades and support.\n\n
\n \n
\n\n## Full-time core team\n\nDioxus has grown from a side project to a small team of fulltime engineers. Thanks to the generous support of FutureWei, Satellite.im, the GitHub Accelerator program, we're able to work on Dioxus full-time. Our long term goal is for Dioxus to become self-sustaining by providing paid high-quality enterprise tools. If your company is interested in adopting Dioxus and would like to work with us, please reach out!\n\n## Supported Platforms\n\n

\n\n## Running the examples\n\n> The examples in the main branch of this repository target the git version of dioxus and the CLI. If you are looking for examples that work with the latest stable release of dioxus, check out the [0.6 branch](https://github.com/DioxusLabs/dioxus/tree/v0.6/examples).\n\nThe examples in the top level of this repository can be run with:\n\n```sh\ncargo run --example \n```\n\nHowever, we encourage you to download the dioxus-cli to test out features like hot-reloading. To install the most recent binary CLI, you can use cargo binstall.\n\n```sh\ncargo binstall dioxus-cli@0.7.0 --force\n```\n\nIf this CLI is out-of-date, you can install it directly from git\n\n```sh\ncargo install --git https://github.com/DioxusLabs/dioxus dioxus-cli --locked\n```\n\nWith the CLI, you can also run examples with the web platform. You will need to disable the default desktop feature and enable the web feature with this command:\n\n```sh\ndx serve --example --platform web -- --no-default-features\n```\n\n## Contributing\n\n- Check out the website [section on contributing](https://dioxuslabs.com/learn/0.7/beyond/contributing).\n- Report issues on our [issue tracker](https://github.com/dioxuslabs/dioxus/issues).\n-

The UI also works on desktop/web,\nbut location calls will return an error because the plugin only supports mobile targetsā€”those\nerrors are shown inline in the demo.\n\n## Things to try\n\n1. Tap **Check permissions** to see the current OS state (granted/denied/prompt).\n2. Tap **Request permissions** to trigger the native dialog from within the app.\n3. Toggle *High accuracy* and set a *Max cached age* before requesting the current position.\n4.

Try running requests against the endpoints directly with `curl` or `postman` to see the actual HTTP responses!\n\nuse dioxus::fullstack::{AsStatusCode, Json, StatusCode};\nuse dioxus::prelude::*;\nuse serde::{Deserialize, Serialize};\n\nfn main() {\n dioxus::launch(|| {\n let mut dog_data = use_action(get_dog_data);\n let mut dog_data_err = use_action(get_dog_data_err);\n let mut ip_data = use_action(get_ip_data);\n let mut custom_data = use_action(move || {\n get_custom_encoding(Json(serde_json::json!({\n \"example\": \"data\",\n \"number\": 123,\n \"array\": [1, 2, 3],\n })))\n });\n let mut error_data = use_action(get_throws_error);\n let mut typed_error_data = use_action(get_throws_typed_error);\n let mut throws_ok_data = use_action(get_throws_ok);\n let mut http_error_data = use_action(throws_http_error);\n let mut http_error_context_data = use_action(throws_http_error_context);\n\n rsx! {\n button { onclick: move |_| { dog_data.call(); }, \"Fetch dog data\" }\n button { onclick: move |_| { ip_data.call(); }, \"Fetch IP data\" }\n button { onclick: move |_| { custom_data.call(); }, \"Fetch custom encoded data\" }\n button { onclick: move |_| { error_data.call(); }, \"Fetch error data\" }\n button { onclick: move |_| { typed_error_data.call(); }, \"Fetch typed error data\" }\n button { onclick: move |_| { dog_data_err.call(); }, \"Fetch dog error data\" }\n button { onclick: move |_| { throws_ok_data.call(); }, \"Fetch throws ok data\" }\n button { onclick: move |_| { http_error_data.call(); }, \"Fetch HTTP 400\" }\n button { onclick: move |_| { http_error_context_data.call(); }, \"Fetch HTTP 400 (context)\" }\n button {\n onclick: move |_| {\n ip_data.reset();\n dog_data.reset();\n custom_data.reset();\n error_data.reset();\n typed_error_data.reset();\n dog_data_err.reset();\n throws_ok_data.reset();\n http_error_data.reset();\n http_error_context_data.reset();\n },\n \"Clear data\"\n }\n div { display: \"flex\", flex_direction: \"column\", gap: \"8px\",\n pre { \"Dog data: {dog_data.value():#?}\" }\n pre { \"IP data: {ip_data.value():#?}\" }\n pre { \"Custom encoded data: {custom_data.value():#?}\" }\n pre { \"Error data: {error_data.value():#?}\" }\n pre { \"Typed error data: {typed_error_data.value():#?}\" }\n pre { \"HTTP 400 data: {http_error_data.value():#?}\" }\n pre { \"HTTP 400 (context) data: {http_error_context_data.value():#?}\" }\n pre { \"Dog error data: {dog_data_err.value():#?}\" }\n pre { \"Throws ok data: {throws_ok_data.value():#?}\" }\n }\n }\n });\n}\n\n/// Simple POST endpoint used to show a successful server function that returns `StatusCode`.\n#[post(\"/api/data\")]\nasync fn post_server_data(data: String) -> Result<(), StatusCode> {\n println!(\"Server received: {}\", data);\n Ok(())\n}\n\n/// Fetches IP info from an external service.

This example is a simple showcase of Dioxus Server Functions.\n//!\n//! The other examples in this folder showcase advanced features of server functions like custom\n//! data types, error handling, websockets, and more.\n//!\n//! This example is meant to just be a simple starting point to show how server functions work.\n//!\n//! ## Server Functions\n//!\n//! In Dioxus, Server Functions are `axum` backend endpoints that can be called directly from the client\n//! as if you were simply calling a local Rust function. You can do anything with a server function\n//! that an Axum handler can do like extracting path, query, headers, and body parameters.\n//!\n//! ## Server Function Arguments\n//!\n//! Unlike Axum handlers, the arguments of the server functions have some special magic enabled by\n//! the accompanying `#[get]`/`#[post]` attributes. This magic enables you to choose between\n//! arguments that are purely serializable (i.e. `String`, `i32`, `Vec`, etc) as the JSON body of\n//!\n//! the request *or* arguments that implement Axum's `FromRequest` trait. This magic enables simple\n//! RPC functions but also complex extractors for things like auth, sessions, cookies, and more.\n//!\n//! ## Server Function Return Types\n//!\n//! The return type of the server function is also somewhat magical. Unlike Axum handlers, all server\n//! functions must return a `Result` type, giving the client an opportunity to handle errors properly.\n//!\n//! The `Ok` type can be anything that implements `Serialize + DeserializeOwned` so it can be sent\n//! to the client as JSON, or it can be anything that implements `IntoResponse` just like an Axum handler.\n//!\n//! ## Error Types\n//!\n//! The `Err` type of the server function return type is also somewhat special. The `Err` type can be:\n//! - `anyhow::Error` (the `dioxus_core::Err` type alias) for untyped errors with rich context. Note\n//! that these errors will always downcast to `ServerFnError` on the client, losing the original\n//! error stack and type.\n//! - `ServerFnError` for typed errors with a status code and optional message.\n//! - `StatusCode` for returning raw HTTP status codes.\n//! - `HttpError` for returning HTTP status codes with custom messages.\n//! - Any custom errors that implement `From` and are `Serialize`/`Deserialize`\n//!\n//! The only way to set the HTTP status code of the response is to use one of the above error types,\n//! or to implement a custom `IntoResponse` type that sets the status code manually.\n//!\n//! The `anyhow::Error` type is the best choice for rapid development, but is somewhat limited when\n//! handling specific error cases on the client since all errors are downcast to `ServerFnError`.\n//!\n//! ## Calling Server Functions from the Client\n//!\n//! Server functions can be called from the client by simply importing the function and calling it\n//! like a normal Rust function. Unlike regular axum handlers, Dioxus server functions have a few\n//! non-obvious restrictions.\n//!\n//! Most importantly, the arguments to the server function must implement either `Deserialize` *or*\n//! `IntoRequest`. The `IntoRequest` trait is a Dioxus abstraction that represents the \"inverse\" of the\n//! Axum `FromRequest` trait. Anything that is sent to the server from the client must be both extractable\n//! with `FromRequest` on the server *and* constructible with `IntoRequest` on the client.\n//!\n//! Types like `WebsocketOptions` implement `IntoRequest` and pass along things like upgrade headers\n//! to the server so that the server can properly upgrade the connection.\n//!\n//! When receiving data from the server, the return type must implement `Deserialize` *or* `FromResponse`.\n//! The `FromResponse` trait is the inverse of Axum's `IntoResponse` trait, and is implemented\n//! for types like `Websocket` where the raw HTTP response is needed to complete the construction\n//! of the type.\n//!\n//! ## Server-only Extractors\n//!\n//! Because the arguments of the server function define the structure of the public API, some extractors\n//! might not make sense to expose directly, nor would they be possible to construct on the client.\n//! For example, on the web, you typically don't work directly with cookies since the browser handles\n//! them for you. In these cases, the client would omit the `Cookie` header entirely, and we would need\n//! \"hoist\" our extractor into a \"server-only extractor\".\n//!\n//! Server-only extractors are function arguments placed after the path in the `#[get]`/`#[post]` attribute.\n//! These arguments are extracted on the server, but not passed in from the client. This lets the\n//! server function remain callable from the client, while still allowing full access to axum's\n//! extractors.\n//!\n//! ```\n//! #[post(\"/api/authenticate\", auth: AuthCookie)]\n//! async fn authenticate() -> Result { /* ... */ }\n//! ```\n//!\n//! ## Automatic Registration\n//!\n//! Unlike axum handlers, server functions do not need to be manually registered with a router.\n//! By default, *all* server functions in your app will be automatically registered with the\n//! server when you call `dioxus::launch` or create a router manually with `dioxus::server::router()`.\n//!\n//! However, not all server functions are automatically registered by default. Server functions that\n//! take a `State` extractor cannot be automatically added to the router since the dioxus router\n//! type does not know how to construct the `T` type.\n//!\n//! These server functions will be registered once the `ServerState` layer is added to the app with\n//! `router = router.layer(ServerState::new(your_state))`.\n//!\n//! ## Middleware\n//!\n//! Middleware can be added to server functions using the `#[middleware(MiddlewareType)]` attribute.\n//! Middleware will be applied in the order they are specified, and will be applied before any\n//! server-only extractors.\n//!\n//! To add router-level middleware, you can customize the axum `Router` using layers and extensions\n//! as you would in a normal axum app.\n//!\n//! ## Anonymous Server Functions\n//!\n//! The `#[server]` attribute can be used without a path to create an anonymous server function.\n//! These functions are still exposed as HTTP endpoints, but their names are procedurally generated\n//! from the module path, function name, and a hash of the function signature. This makes it hard to\n//! call these functions with `curl` or `postman`, but save you the trouble of coming up with unique\n//! names for simple functions that are only called from your Dioxus app.\n//!\n//! If you're shipping desktop/mobile apps, we don't recommend using anonymous server functions\n//! since the function names could change between builds and thus make older versions of your app\n//! incompatible with newer versions of your server.\n//!\n//! ## Cross-platform Clients\n//!\n//! Server functions can be called from any platform (web, desktop mobile, etc) and use the best\n//! underlying `fetch` implementation available.\n//!\n//! ## More examples\n//!\n//! With Dioxus Fullstack 0.7, pretty much anything you can do with an Axum handler, you can do with\n//! a server function. More advanced examples can be found in this folder showcasing custom data types,\n//! error handling, websockets, and more.\n\nuse axum_core::response::IntoResponse;\nuse dioxus::prelude::*;\nuse dioxus_fullstack::FromResponse;\nuse dioxus_fullstack::http::StatusCode;\nuse serde::{Deserialize, Serialize};\n\nfn main() {\n dioxus::launch(app);\n}\n\nfn app() -> Element {\n let mut echo_action = use_action(echo);\n let mut chat_action = use_action(chat);\n let mut dog_data = use_action(get_data);\n let mut custom_data = use_action(get_custom_data);\n let mut anonymous_action = use_action(anonymous);\n let mut custom_anonymous_action = use_action(custom_anonymous);\n let mut custom_response_action = use_action(get_custom_response);\n\n rsx! {\n h1 { \"Server Functions Example\" }\n div {\n display: \"flex\",\n flex_direction: \"column\",\n gap: \"8px\",\n\n button { onclick: move |_| echo_action.call(\"Hello from client\".into()), \"Echo: Hello\" }\n button { onclick: move |_| chat_action.call(42u32, Some(7u32)), \"Chat (user 42, room 7)\" }\n button { onclick: move |_| dog_data.call(), \"Get dog data\" }\n button { onclick: move |_| custom_data.call(), \"Get custom data\" }\n button { onclick: move |_| anonymous_action.call(), \"Call anonymous\" }\n button { onclick: move |_| custom_anonymous_action.call(), \"Call custom anonymous\" }\n button { onclick: move |_| custom_response_action.call(), \"Get custom response\" }\n\n button {\n onclick: move |_| {\n echo_action.reset();\n chat_action.reset();\n dog_data.reset();\n custom_data.reset();\n anonymous_action.reset();\n custom_anonymous_action.reset();\n custom_response_action.reset();\n },\n \"Clear results\"\n }\n\n pre { \"Echo result: {echo_action.value():#?}\" }\n pre { \"Chat result: {chat_action.value():#?}\" }\n pre { \"Dog data: {dog_data.value():#?}\" }\n pre { \"Custom data: {custom_data.value():#?}\" }\n pre { \"Anonymous: {anonymous_action.value():#?}\" }\n pre { \"Custom anonymous: {custom_anonymous_action.value():#?}\" }\n pre { \"Custom response: {custom_response_action.value():#?}\" }\n }\n }\n}\n\n/// A plain server function at a `POST` endpoint that takes a string and returns it.\n/// Here, we use the `Result` return type which is an alias to `Result`.\n#[post(\"/api/echo\")]\nasync fn echo(body: String) -> Result {\n Ok(body)\n}\n\n/// A Server function that takes path and query parameters, as well as a server-only extractor.\n#[post(\"/api/{user_id}/chat?room_id\", headers: dioxus_fullstack::HeaderMap)]\nasync fn chat(user_id: u32, room_id: Option) -> Result {\n Ok(format!(\n \"User ID: {}, Room ID: {} - Headers: {:#?}\",\n user_id,\n room_id.map_or(\"None\".to_string(), |id| id.to_string()),\n headers\n ))\n}\n\n/// A plain server function at a `GET` endpoint that returns some JSON data.

This example demonstrates server-sent events (SSE) using Dioxus Fullstack.\n//!\n//! Server-sent events allow the server to push updates to the client over a single HTTP connection.\n//!

SSE is a simpler alternative to WebSockets, not requiring a full-duplex, stateful connection with\n//! the server.

The dioxus asset system.\n//!\n//! This module provides functionality for extracting assets from a binary file and then writing back\n//! their asset hashes directly into the binary file. Previously, we performed asset hashing in the\n//! `asset!()` macro. The new system, implemented here, instead performs the hashing at build time,\n//! which provides more flexibility in the asset processing pipeline.\n//!\n//! We chose to implement this approach since assets might reference each other which means we minimally\n//! need to parse the asset to create a unique hash for each asset before they are used in the application.\n//! The hashes are used both for cache busting the asset in the browser and to cache the asset optimization\n//! process in the build system.\n//!\n//! We use the same lessons learned from the hot-patching engine which parses the binary file and its\n//! symbol table to find symbols that match the `__ASSETS__` prefix. These symbols are ideally data\n//! symbols and contain the BundledAsset data type which implements ConstSerialize and ConstDeserialize.\n//!\n//! When the binary is built, the `dioxus asset!()` macro will emit its metadata into the __ASSETS__\n//! symbols, which we process here. After reading the metadata directly from the executable, we then\n//! hash it and write the hash directly into the binary file.\n//!\n//! During development, we can skip this step for most platforms since local paths are sufficient\n//! for asset loading. However, for WASM and for production builds, we need to ensure that assets\n//! can be found relative to the current exe. Unfortunately, on android, the `current_exe` path is wrong,\n//! so the assets are resolved against the \"asset root\" - which is covered by the asset loader crate.\n//!\n//! Finding the __ASSETS__ symbols is not quite straightforward when hotpatching, especially on WASM\n//! since we build and link the module as relocatable, which is not a stable WASM proposal. In this\n//! implementation, we handle both the non-PIE *and* PIC cases which are rather bespoke to our whole\n//! build system.\n\nuse std::{\n io::{Cursor, Read, Seek, Write},\n path::{Path, PathBuf},\n};\n\nuse crate::Result;\nuse anyhow::{bail, Context};\nuse const_serialize::{deserialize_const, serialize_const, ConstVec};\nuse dioxus_cli_opt::AssetManifest;\nuse manganis::{AssetOptions, AssetVariant, BundledAsset, ImageFormat, ImageSize};\nuse manganis_core::{AndroidArtifactMetadata, SwiftPackageMetadata, SymbolData};\nuse object::{File, Object, ObjectSection, ObjectSymbol, ReadCache, ReadRef, Section, Symbol};\nuse pdb::FallibleIterator;\nuse rayon::iter::{IntoParallelRefMutIterator, ParallelIterator};\n\n/// Extract all manganis symbols and their sections from the given object file.\nfn manganis_symbols<'a, 'b, R: ReadRef<'a>>(\n file: &'b File<'a, R>,\n) -> impl Iterator, Section<'a, 'b, R>)> + 'b {\n file.symbols().filter_map(move |symbol| {\n let name = symbol.name().ok()?;\n let version = looks_like_manganis_symbol(name)?;\n let section_index = symbol.section_index()?;\n let section = file.section_by_index(section_index).ok()?;\n Some((version, symbol, section))\n })\n}\n\n#[derive(Copy, Clone)]\nenum ManganisVersion {\n /// The legacy version of the manganis format published with 0.7.0 and 0.7.1\n Legacy,\n /// The new version of the manganis format 0.7.2 onward\n /// This now includes both assets (old BundledAsset format) and permissions (SymbolData format)\n New,\n}\n\nimpl ManganisVersion {\n fn size(&self) -> usize {\n match self {\n ManganisVersion::Legacy => {\n ::MEMORY_LAYOUT.size()\n }\n // For new format, we use a larger buffer size to accommodate variable-length CBOR\n // The actual size will be determined by CBOR deserialization\n ManganisVersion::New => 4096,\n }\n }\n\n /// Deserialize data, trying multiple formats for backward compatibility\n ///\n /// Tries in order:\n /// 1.

The [`BuildRequest`] object is the core of the build process. It contains all the resolved arguments\n//! flowing in from the CLI, dioxus.toml, env vars, and the workspace.\n//!\n//! Every BuildRequest is tied to a given workspace and BuildArgs. For simplicity's sake, the BuildArgs\n//! struct is used to represent the CLI arguments and all other configuration is basically just\n//! extra CLI arguments, but in a configuration format.\n//!\n//! When [`BuildRequest::build`] is called, it will prepare its work directory in the target folder\n//! and then start running the build process. A [`BuildContext`] is required to customize this\n//! build process, containing a channel for progress updates and the build mode.\n//!\n//! The [`BuildMode`] is extremely important since it influences how the build is performed. Most\n//! \"normal\" builds just use [`BuildMode::Base`], but we also support [`BuildMode::Fat`] and\n//! [`BuildMode::Thin`]. These builds are used together to power the hot-patching and fast-linking\n//! engine.\n//! - BuildMode::Base: A normal build generated using `cargo rustc`\n//! - BuildMode::Fat: A \"fat\" build where all dependency rlibs are merged into a static library\n//! - BuildMode::Thin: A \"thin\" build that dynamically links against the artifacts produced by the \"fat\" build\n//!\n//! The BuildRequest is also responsible for writing the final build artifacts to disk. This includes\n//!\n//! - Writing the executable\n//! - Processing assets from the artifact\n//! - Writing any metadata or configuration files (Info.plist, AndroidManifest.xml)\n//! - Bundle splitting (for wasm) and wasm-bindgen\n//!\n//! In some cases, the BuildRequest also handles the linking of the final executable. Specifically,\n//! - For Android, we use `dx` as an opaque linker to dynamically find the true android linker\n//! - For hotpatching, the CLI manually links the final executable with a stub file\n//!\n//! ## Build formats:\n//!\n//! We support building for the most popular platforms:\n//! - Web via wasm-bindgen\n//! - macOS via app-bundle\n//! - iOS via app-bundle\n//! - Android via gradle\n//! - Linux via app-image\n//! - Windows via exe, msi/msix\n//!\n//! Note that we are missing some setups that we *should* support:\n//! - PWAs, WebWorkers, ServiceWorkers\n//! - Web Extensions\n//! - Linux via flatpak/snap\n//!\n//! There are some less popular formats that we might want to support eventually:\n//! - TVOS, watchOS\n//! - OpenHarmony\n//!\n//! Also, some deploy platforms have their own bespoke formats:\n//! - Cloudflare workers\n//! - AWS Lambda\n//!\n//! Currently, we defer most of our deploy-based bundling to Tauri bundle, though we should migrate\n//! to just bundling everything ourselves. This would require us to implement code-signing which\n//! is a bit of a pain, but fortunately a solved process ().\n//!\n//! ## Build Structure\n//!\n//! Builds generally follow the same structure everywhere:\n//! - A main executable\n//! - Sidecars (alternate entrypoints, framewrok plugins, etc)\n//! - Assets (images, fonts, etc)\n//! - Metadata (Info.plist, AndroidManifest.xml)\n//! - Glue code (java, kotlin, javascript etc)\n//! - Entitlements for code-signing and verification\n//!\n//! We need to be careful to not try and put a \"round peg in a square hole,\" but most platforms follow\n//! the same pattern.\n//!\n//! As such, we try to assemble a build directory that's somewhat sensible:\n//! - A main \"staging\" dir for a given app\n//! - Per-profile dirs (debug/release)\n//! - A platform dir (ie web/desktop/android/ios)\n//! - The \"bundle\" dir which is basically the `.app` format or `wwww` dir.\n//! - The \"executable\" dir where the main exe is housed\n//! - The \"assets\" dir where the assets are housed\n//! - The \"meta\" dir where stuff like Info.plist, AndroidManifest.xml, etc are housed\n//!\n//! There's also some \"quirky\" folders that need to be stable between builds but don't influence the\n//! bundle itself:\n//! - session_cache_dir which stores stuff like window position\n//!\n//! ### Web:\n//!\n//! Create a folder that is somewhat similar to an app-image (exe + asset)\n//! The server is dropped into the `web` folder, even if there's no `public` folder.\n//! If there's no server (SPA), we still use the `web` folder, but it only contains the\n//! public folder.\n//!\n//! ```\n//! web/\n//! server\n//! assets/\n//! public/\n//! index.html\n//! wasm/\n//! app.wasm\n//! glue.js\n//! snippets/\n//! ...\n//! assets/\n//! logo.png\n//! ```\n//!\n//! ### Linux:\n//!\n//! \n//! current_exe.join(\"Assets\")\n//! ```\n//! app.appimage/\n//! AppRun\n//! app.desktop\n//! package.json\n//! assets/\n//! logo.png\n//! ```\n//!\n//! ### Macos\n//!\n//! We simply use the macos format where binaries are in `Contents/MacOS` and assets are in `Contents/Resources`\n//! We put assets in an assets dir such that it generally matches every other platform and we can\n//! output `/assets/blah` from manganis.\n//! ```\n//! App.app/\n//! Contents/\n//! Info.plist\n//! MacOS/\n//! Frameworks/\n//! Resources/\n//! assets/\n//! blah.icns\n//! blah.png\n//! CodeResources\n//! _CodeSignature/\n//! ```\n//!\n//! ### iOS\n//!\n//! Not the same as mac! ios apps are a bit \"flattened\" in comparison. simpler format, presumably\n//! since most ios apps don't ship frameworks/plugins and such.\n//!\n//! todo(jon): include the signing and entitlements in this format diagram.\n//! ```\n//! App.app/\n//! main\n//! assets/\n//! ```\n//!\n//! ### Android:\n//!\n//! Currently we need to generate a `src` type structure, not a pre-packaged apk structure, since\n//! we need to compile kotlin and java. This pushes us into using gradle and following a structure\n//! similar to that of cargo mobile2. Eventually I'd like to slim this down (drop buildSrc) and\n//! drive the kotlin build ourselves. This would let us drop gradle (yay! no plugins!) but requires\n//! us to manage dependencies (like kotlinc) ourselves (yuck!).\n//!\n//! \n//!\n//! Unfortunately, it seems that while we can drop the `android` build plugin, we still will need\n//! gradle since kotlin is basically gradle-only.\n//!\n//! Pre-build:\n//! ```\n//! app.apk/\n//! .gradle\n//! app/\n//! src/\n//! main/\n//! assets/\n//! jniLibs/\n//! java/\n//! kotlin/\n//! res/\n//! AndroidManifest.xml\n//! build.gradle.kts\n//! proguard-rules.pro\n//! buildSrc/\n//! build.gradle.kts\n//! src/\n//! main/\n//! kotlin/\n//! BuildTask.kt\n//! build.gradle.kts\n//! gradle.properties\n//! gradlew\n//! gradlew.bat\n//! settings.gradle\n//! ```\n//!\n//! Final build:\n//! ```\n//! app.apk/\n//! AndroidManifest.xml\n//! classes.dex\n//! assets/\n//! logo.png\n//! lib/\n//! armeabi-v7a/\n//! libmyapp.so\n//! arm64-v8a/\n//! libmyapp.so\n//! x86/\n//! libmyapp.so\n//! x86_64/\n//! libmyapp.so\n//! ```\n//! Notice that we *could* feasibly build this ourselves :)\n//!\n//! ### Windows:\n//! \n//! Windows does not provide an AppImage format, so instead we're going build the same folder\n//! structure as an AppImage, but when distributing, we'll create a .exe that embeds the resources\n//! as an embedded .zip file. When the app runs, it will implicitly unzip its resources into the\n//! Program Files folder. Any subsequent launches of the parent .exe will simply call the AppRun.exe\n//! entrypoint in the associated Program Files folder.\n//!\n//! This is, in essence, the same as an installer, so we might eventually just support something like msi/msix\n//! which functionally do the same thing but with a sleeker UI.\n//!\n//! This means no installers are required and we can bake an updater into the host exe.\n//!\n//! ## Handling asset lookups:\n//! current_exe.join(\"assets\")\n//! ```\n//! app.appimage/\n//! main.exe\n//! main.desktop\n//! package.json\n//! assets/\n//! logo.png\n//! ```\n//!\n//! Since we support just a few locations, we could just search for the first that exists\n//! - usr\n//! - ../Resources\n//! - assets\n//! - Assets\n//! - $cwd/assets\n//!\n//! ```\n//! assets::root() ->\n//! mac -> ../Resources/\n//! ios -> ../Resources/\n//! android -> assets/\n//! server -> assets/\n//! liveview -> assets/\n//! web -> /assets/\n//! root().join(bundled)\n//! ```\n//!\n//! Every dioxus app can have an optional server executable which will influence the final bundle.\n//! This is built in parallel with the app executable during the `build` phase and the progres/status\n//! of the build is aggregated.\n//!\n//! The server will *always* be dropped into the `web` folder since it is considered \"web\" in nature,\n//! and will likely need to be combined with the public dir to be useful.\n//!\n//! We do our best to assemble read-to-go bundles here, such that the \"bundle\" step for each platform\n//! can just use the build dir\n//!\n//! When we write the AppBundle to a folder, it'll contain each bundle for each platform under the app's name:\n//! ```\n//! dog-app/\n//! build/\n//! web/\n//! server.exe\n//! assets/\n//! some-secret-asset.txt (a server-side asset)\n//! public/\n//! index.html\n//! assets/\n//! logo.png\n//! desktop/\n//! App.app\n//! App.appimage\n//! App.exe\n//! server/\n//! server\n//! assets/\n//! some-secret-asset.txt (a server-side asset)\n//! ios/\n//! App.app\n//! App.ipa\n//! android/\n//! App.apk\n//! bundle/\n//! build.json\n//! Desktop.app\n//! Mobile_x64.ipa\n//! Mobile_arm64.ipa\n//!

When deploying, the build.json file will provide all the metadata that dx-deploy will use to\n//! push the app to stores, set up infra, manage versions, etc.\n//!\n//! The format of each build will follow the name plus some metadata such that when distributing you\n//! can easily trim off the metadata.\n//!\n//! The idea here is that we can run any of the programs in the same way that they're deployed.\n//!\n//! ## Bundle structure links\n//! - apple: \n//! - appimage: \n//!\n//! ## Extra links\n//! - xbuild: \n\nuse super::HotpatchModuleCache;\nuse crate::{\n AndroidTools, AppManifest, BuildContext, BuildId, BundleFormat, DioxusConfig, Error,\n LinkAction, LinkerFlavor, ObjectCache, Platform, Renderer, Result, RustcArgs, TargetArgs,\n TraceSrc, WasmBindgen, WasmOptConfig, Workspace, DX_RUSTC_WRAPPER_ENV_VAR,\n};\nuse anyhow::{bail, Context};\nuse cargo_metadata::diagnostic::Diagnostic;\nuse cargo_toml::{Profile, Profiles, StripSetting};\nuse depinfo::RustcDepInfo;\nuse dioxus_cli_config::{format_base_path_meta_element, PRODUCT_NAME_ENV};\nuse dioxus_cli_config::{APP_TITLE_ENV, ASSET_ROOT_ENV};\nuse dioxus_cli_opt::{process_file_to, AssetManifest};\nuse itertools::Itertools;\nuse krates::{cm::TargetKind, NodeId};\nuse manganis::{AssetOptions, BundledAsset, SwiftPackageMetadata};\nuse manganis_core::{AndroidArtifactMetadata, AssetVariant};\nuse rayon::prelude::{IntoParallelRefIterator, ParallelIterator};\nuse serde::{Deserialize, Serialize};\nuse std::{borrow::Cow, ffi::OsString};\nuse std::{\n collections::{BTreeMap, HashMap, HashSet},\n io::Write,\n path::{Path, PathBuf},\n process::Stdio,\n sync::{\n atomic::{AtomicUsize, Ordering},\n Arc,\n },\n time::{SystemTime, UNIX_EPOCH},\n};\nuse subsecond_types::JumpTable;\nuse target_lexicon::{Architecture, OperatingSystem, Triple};\nuse tempfile::TempDir;\nuse tokio::{io::AsyncBufReadExt, process::Command};\nuse uuid::Uuid;\n\n/// This struct is used to plan the build process.\n///\n/// The point here is to be able to take in the user's config from the CLI without modifying the\n/// arguments in place.
