# Contributor Code of Conduct

As contributors and maintainers of this project, we pledge to respect all people who contribute through reporting issues, posting feature requests, updating documentation, submitting pull requests or patches, and other activities.

We are committed to making participation in this project a harassment-free experience for everyone, regardless of the level of experience, gender, gender identity and expression, sexual orientation, disability, personal appearance, body size, race, age, or religion.

Examples of unacceptable behavior by participants include the use of sexual language or imagery, derogatory comments or personal attacks, trolling, public or private harassment, insults, or other unprofessional conduct.

Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct. Project maintainers who do not follow the Code of Conduct may be removed from the project team.

Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by opening an issue or contacting one or more of the project maintainers.

This Code of Conduct is adapted from the [Contributor Covenant](https://contributor-covenant.org), version 1.0.0, available at [http://contributor-covenant.org/version/1/0/0/](http://contributor-covenant.org/version/1/0/0/)

FILE: .github/COMMIT_CONVENTION.md
================================================
## Git Commit Message Convention

> This is adapted from [Angular's commit convention](https://github.com/conventional-changelog/conventional-changelog/tree/master/packages/conventional-changelog-angular).

#### TL;DR:

Messages must be matched by the following regex:

``` js
/^(revert: )?(feat|fix|polish|docs|style|refactor|perf|test|workflow|ci|chore|types)(\(.+\))?: .{1,50}/
```

#### Examples

Appears under "Features" header, `compiler` subheader:

```
feat(compiler): add 'comments' option
```

Appears under "Bug Fixes" header, `v-model` subheader, with a link to issue #28:

```
fix(v-model): handle events on blur

close #28
```

Appears under "Performance Improvements" header, and under "Breaking Changes" with the breaking change explanation:

```
perf(core): improve vdom diffing by removing 'foo' option

BREAKING CHANGE: The 'foo' option has been removed.
```

The following commit and commit `667ecc1` do not appear in the changelog if they are under the same release. If not, the revert commit appears under the "Reverts" header.

```
revert: feat(compiler): add 'comments' option

This reverts commit 667ecc1654a317a13331b17617d973392f415f02.
```

### Full Message Format

A commit message consists of a **header**, **body** and **footer**.  The header has a **type**, **scope** and **subject**:

```
<type>(<scope>): <subject>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>
```

The **header** is mandatory and the **scope** of the header is optional.

### Revert

If the commit reverts a previous commit, it should begin with `revert: `, followed by the header of the reverted commit. In the body, it should say: `This reverts commit <hash>.`, where the hash is the SHA of the commit being reverted.

### Type

If the prefix is `feat`, `fix` or `perf`, it will appear in the changelog. However, if there is any [BREAKING CHANGE](#footer), the commit will always appear in the changelog.

Other prefixes are up to your discretion. Suggested prefixes are `docs`, `chore`, `style`, `refactor`, and `test` for non-changelog related tasks.

### Scope

The scope could be anything specifying the place of the commit change. For example `core`, `compiler`, `ssr`, `v-model`, `transition` etc...

### Subject

The subject contains a succinct description of the change:

* use the imperative, present tense: "change" not "changed" nor "changes"
* don't capitalize the first letter
* no dot (.) at the end

### Body

Just as in the **subject**, use the imperative, present tense: "change" not "changed" nor "changes".
The body should include the motivation for the change and contrast this with previous behavior.

### Footer

The footer should contain any information about **Breaking Changes** and is also the place to
reference GitHub issues that this commit **Closes**.

**Breaking Changes** should start with the word `BREAKING CHANGE:` with a space or two newlines. The rest of the commit message is then used for this.

# Vue.js Contributing Guide

Hi! I'm really excited that you are interested in contributing to Vue.js. Before submitting your contribution, please make sure to take a moment and read through the following guidelines:

- [Code of Conduct](https://github.com/vuejs/vue/blob/dev/.github/CODE_OF_CONDUCT.md)
- [Issue Reporting Guidelines](#issue-reporting-guidelines)
- [Pull Request Guidelines](#pull-request-guidelines)
- [Development Setup](#development-setup)
- [Project Structure](#project-structure)

## Issue Reporting Guidelines

- Always use [https://new-issue.vuejs.org/](https://new-issue.vuejs.org/) to create new issues.

## Pull Request Guidelines

- The `master` branch is just a snapshot of the latest stable release. All development should be done in dedicated branches. **Do not submit PRs against the `master` branch.**

- Checkout a topic branch from the relevant branch, e.g. `dev`, and merge back against that branch.

- Work in the `src` folder and **DO NOT** checkin `dist` in the commits.

- It's OK to have multiple small commits as you work on the PR - GitHub will automatically squash it before merging.

- Make sure `npm test` passes. (see [development setup](#development-setup))

- If adding a new feature:

  - Add accompanying test case.
  - Provide a convincing reason to add this feature. Ideally, you should open a suggestion issue first and have it approved before working on it.

- If fixing bug:
  - If you are resolving a special issue, add `(fix #xxxx[,#xxxx])` (#xxxx is the issue id) in your PR title for a better release log, e.g. `update entities encoding/decoding (fix #3899)`.
  - Provide a detailed description of the bug in the PR. Live demo preferred.
  - Add appropriate test coverage if applicable.

## Development Setup

You will need [Node.js](https://nodejs.org) **version 18+** and [pnpm](https://pnpm.io/) **version 8+**.

After cloning the repo, run:

```bash
$ pnpm i # install the dependencies of the project
```

### Committing Changes

Commit messages should follow the [commit message convention](./COMMIT_CONVENTION.md) so that changelogs can be automatically generated. Commit messages will be automatically validated upon commit. If you are not familiar with the commit message convention, you can use `npm run commit` instead of `git commit`, which provides an interactive CLI for generating proper commit messages.

### Commonly used NPM scripts

```bash
# watch and auto re-build dist/vue.js
$ npm run dev

# run unit tests
$ npm run test:unit

# run specific tests in watch mode
$ npx vitest {test_file_name_pattern_to_match}

# build all dist files, including npm packages
$ npm run build

# run the full test suite, including unit/e2e/type checking
$ npm test
```

There are some other scripts available in the `scripts` section of the `package.json` file.

The default test script will do the following: lint with ESLint -> type check with Flow -> unit tests with coverage -> e2e tests. **Please make sure to have this pass successfully before submitting a PR.** Although the same tests will be run against your PR on the CI server, it is better to have it working locally.

## Project Structure

- **`scripts`**: contains build-related scripts and configuration files. Usually, you don't need to touch them. However, it would be helpful to familiarize yourself with the following files:

  - `scripts/alias.js`: module import aliases used across all source code and tests.

  - `scripts/config.js`: contains the build configurations for all files found in `dist/`. Check this file if you want to find out the entry source file for a dist file.

- **`dist`**: contains built files for distribution. Note this directory is only updated when a release happens; they do not reflect the latest changes in development branches.

  See [dist/README.md](https://github.com/vuejs/vue/blob/dev/dist/README.md) for more details on dist files.

- **`types`**: contains public types published to npm (note the types shipped here could be different from `src/types`). These were hand-authored before we moved the codebase from Flow to TypeScript. To ensure backwards compatibility, we keep using these manually authored types.

  Types for new features added in 2.7 (Composition API) are auto-generated from source code as `types/v3-generated.d.ts` and re-exported from `types/index.d.ts`.

- **`packages`**:

  - `vue-server-renderer` and `vue-template-compiler` are distributed as separate NPM packages. They are automatically generated from the source code and always have the same version with the main `vue` package.

  - `compiler-sfc` is an internal package that is distributed as part of the main `vue` package. It's aliased and can be imported as `vue/compiler-sfc` similar to Vue 3.

- **`test`**: contains all tests. The unit tests are written with [Jasmine](http://jasmine.github.io/2.3/introduction.html) and run with [Karma](http://karma-runner.github.io/0.13/index.html). The e2e tests are written for and run with [Nightwatch.js](http://nightwatchjs.org/).

- **`src`**: contains the source code. The codebase is written in ES2015 with [Flow](https://flowtype.org/) type annotations.

  - **`compiler`**: contains code for the template-to-render-function compiler.

    The compiler consists of a parser (converts template strings to element ASTs), an optimizer (detects static trees for vdom render optimization), and a code generator (generate render function code from element ASTs). Note that codegen directly generates code strings from the element AST - it's done this way for smaller code size because the compiler is shipped to the browser in the standalone build.

  - **`core`**: contains universal, platform-agnostic runtime code.

    The Vue 2.0 core is platform-agnostic. That is, the code inside `core` is able to be run in any JavaScript environment, be it the browser, Node.js, or an embedded JavaScript runtime in native applications.

    - **`observer`**: contains code related to the reactivity system.

    - **`vdom`**: contains code related to vdom element creation and patching.

    - **`instance`**: contains Vue instance constructor and prototype methods.

    - **`global-api`**: contains Vue global api.

    - **`components`**: contains universal abstract components.

  - **`server`**: contains code related to server-side rendering.

  - **`platforms`**: contains platform-specific code.

    Entry files for dist builds are located in their respective platform directory.

    Each platform module contains three parts: `compiler`, `runtime` and `server`, corresponding to the three directories above. Each part contains platform-specific modules/utilities which are imported and injected to the core counterparts in platform-specific entry files. For example, the code implementing the logic behind `v-bind:class` is in `platforms/web/runtime/modules/class.js` - which is imported in `platforms/web/entry-runtime.ts` and used to create the browser-specific vdom patching function.

  - **`sfc`**: contains single-file component (`*.vue` files) parsing logic. This is used in the `vue-template-compiler` package.

  - **`shared`**: contains utilities shared across the entire codebase.

  - **`types`**: contains type declarations added when we ported the codebase from Flow to TypeScript. These types should be considered internal - they care less about type inference for end-user scenarios and prioritize working with internal source code.

# [2.7.0](https://github.com/vuejs/vue/compare/v2.7.0-beta.8...v2.7.0) (2022-07-01)

## Backported Features

- [Composition API](https://vuejs.org/guide/extras/composition-api-faq.html)
- SFC [`<script setup>`](https://vuejs.org/api/sfc-script-setup.html)
- SFC [CSS v-bind](https://vuejs.org/api/sfc-css-features.html#v-bind-in-css)

In addition, the following APIs are also supported:

- `defineComponent()` with improved type inference (compared to `Vue.extend`)
- `h()`, `useSlot()`, `useAttrs()`, `useCssModules()`
- `set()`, `del()` and `nextTick()` are also provided as named exports in ESM builds.
- The `emits` option is also supported, but only for type-checking purposes (does not affect runtime behavior)

  2.7 also supports using ESNext syntax in template expressions. When using a build system, the compiled template render function will go through the same loaders / plugins configured for normal JavaScript. This means if you have configured Babel for `.js` files, it will also apply to the expressions in your SFC templates.

### Notes on API exposure

- In ESM builds, these APIs are provided as named exports (and named exports only):

  ```js
  import Vue, { ref } from 'vue'

  Vue.ref // undefined, use named export instead
  ```

- In UMD and CJS builds, these APIs are exposed as properties on the global `Vue` object.

- When bundling with CJS builds externalized, bundlers should be able to handle ESM interop when externalizing CJS builds.

### Behavior Differences from Vue 3

The Composition API is backported using Vue 2's getter/setter-based reactivity system to ensure browser compatibility. This means there are some important behavior differences from Vue 3's proxy-based system:

- All [Vue 2 change detection caveats](https://v2.vuejs.org/v2/guide/reactivity.html#Change-Detection-Caveats) still apply.

- `reactive()`, `ref()`, and `shallowReactive()` will directly convert original objects instead of creating proxies. This means:

  ```js
  // true in 2.7, false in 3.x
  reactive(foo) === foo
  ```

- `readonly()` **does** create a separate object, but it won't track newly added properties and does not work on arrays.

- Avoid using arrays as root values in `reactive()` because without property access the array's mutation won't be tracked (this will result in a warning).

- Reactivity APIs ignore properties with symbol keys.

In addition, the following features are explicitly **NOT** ported:

- ❌ `createApp()` (Vue 2 doesn't have isolated app scope)
- ❌ Top-level `await` in `<script setup>` (Vue 2 does not support async component initialization)
- ❌ TypeScript syntax in template expressions (incompatible w/ Vue 2 parser)
- ❌ Reactivity transform (still experimental)
- ❌ `expose` option is not supported for options components (but `defineExpose()` is supported in `<script setup>`).

### TypeScript Changes

- `defineComponent` provides improved type inference similar to that of Vue 3. Note the type of `this` inside `defineComponent()` is not interoperable with `this` from `Vue.extend()`.

- Similar to Vue 3, TSX support is now built-in. If your project previously had manual JSX type shims, make sure to remove them.

## Upgrade Guide

### Vue CLI / webpack

1. Upgrade local `@vue/cli-xxx` dependencies the latest version in your major version range (if applicable):

   - `~4.5.18` for v4
   - `~5.0.6` for v5

2. Upgrade `vue` to `^2.7.0`. You can also remove `vue-template-compiler` from the dependencies - it is no longer needed in 2.7.

   Note: if you are using `@vue/test-utils`, you may need to keep it in the dependencies for now, but this requirement will also be lifted in a new release of test utils.

3. Check your package manager lockfile to ensure the following dependencies meet the version requirements. They may be transitive dependencies not listed in `package.json`.

   - `vue-loader`: `^15.10.0`
   - `vue-demi`: `^0.13.1`

   If not, you will need to remove `node_modules` and the lockfile and perform a fresh install to ensure they are bumped to the latest version.

4. If you were previously using [`@vue/composition-api`](https://github.com/vuejs/composition-api), update imports from it to `vue` instead. Note that some APIs exported by the plugin, e.g. `createApp`, are not ported in 2.7.

5. Update `eslint-plugin-vue` to latest version (9+) if you run into unused variable lint errors when using `<script setup>`.

6. The SFC compiler for 2.7 now uses PostCSS 8 (upgraded from 7). PostCSS 8 should be backwards compatible with most plugins, but the upgrade **may** cause issues if you were previously using a custom PostCSS plugin that can only work with PostCSS 7. In such cases, you will need to upgrade the relevant plugins to their PostCSS 8 compatible versions.

### Vite

2.7 support for Vite is provided via a new plugin: [@vitejs/plugin-vue2](https://github.com/vitejs/vite-plugin-vue2). This new plugin requires Vue 2.7 or above and supersedes the existing [vite-plugin-vue2](https://github.com/underfin/vite-plugin-vue2).

Note that the new plugin does not handle Vue-specific JSX / TSX transform, which is intentional. Vue 2 JSX / TSX transform should be handled in a separate, dedicated plugin, which will be provided soon.

### Volar Compatibility

2.7 ships improved type definitions so it is no longer necessary to install `@vue/runtime-dom` just for Volar template type inference support. All you need now is the following config in `tsconfig.json`:

```json
{
  // ...
  "vueCompilerOptions": {
    "target": 2.7
  }
}
```

### Devtools Support

Vue Devtools 6.2.0 has added support for inspecting 2.7 Composition API state, but the extensions may still need a few days to go through review on respective publishing platforms.

### Bug Fixes

* **sfc:** only include legacy decorator parser plugin when new plugin is not used ([326d24a](https://github.com/vuejs/vue/commit/326d24a4e42b4f4fd243b36037e88b71963d963d))

# [2.7.0-alpha.1](https://github.com/vuejs/vue/compare/v2.6.14...v2.7.0-alpha.1) (2022-05-31)

This release includes full [Composition API](https://vuejs.org/guide/extras/composition-api-faq.html) support, including:

- `setup()` support in components
- Reactivity APIs (`ref()`, `reactive()` etc.)
- Lifecycle hooks (`onMounted()` etc.)
- `provide()` and `inject()`
- `useSlots()` and `useAttrs()`
- template refs with `setup()`

### Behavior difference from Vue 3

- The reactivity system is still getter/setter based and does not use Proxies, so all Vue 2 change detection caveats still apply.
- `reactive()`, `ref()`, and `shallowReactive()` will directly convert original objects instead of creating proxies. They also do not convert properties with symbol keys.
- Avoid using arrays as root values in `reactive()` because without property access the array's mutation won't be tracked (this will result in a warning).
- `readonly()` **does** create a separate object, but it won't track newly added properties and does not work on arrays.

### Notes on API exposure

- In ESM builds, these APIs are provided as named exports (and named exports only):

  ```js
  import Vue, { ref } from 'vue'

  Vue.ref // undefined, use named export instead
  ```

- When bundling with CJS builds externalized, bundlers should be able to handle ESM interop when externalizing CJS builds.

- In UMD builds, these APIs are exposed on the global `Vue` object.

In addition:

- `h()`, `set()`, `del()` and `nextTick()` are now also provided as named exports in ESM builds.

## Vue 2 has reached End of Life

**You are looking at the now inactive repository for Vue 2. The actively maintained repository for the latest version of Vue is [vuejs/core](https://github.com/vuejs/core).**

Vue has reached End of Life on December 31st, 2023. It no longer receives new features, updates, or fixes. However, it is still available on all existing distribution channels (CDNs, package managers, Github, etc).

If you are starting a new project, please start with the latest version of Vue (3.x). We also strongly recommend current Vue 2 users to upgrade ([guide](https://v3-migration.vuejs.org/)), but we also acknowledge that not all users have the bandwidth or incentive to do so. If you have to stay on Vue 2 but also have compliance or security requirements about unmaintained software, check out [Vue 2 NES](https://www.herodevs.com/support/nes-vue?utm_source=vuejs-github&utm_medium=vue2-readme).

## Introduction

Vue (pronounced `/vjuː/`, like view) is a **progressive framework** for building user interfaces. It is designed from the ground up to be incrementally adoptable, and can easily scale between a library and a framework depending on different use cases. It consists of an approachable core library that focuses on the view layer only, and an ecosystem of supporting libraries that helps you tackle complexity in large Single-Page Applications.

#### Browser Compatibility

Vue.js supports all browsers that are [ES5-compliant](https://compat-table.github.io/compat-table/es5/) (IE8 and below are not supported).
