This is the repository for Vue 3.0.

## Quickstart

- Via CDN: `<script src="https://unpkg.com/vue@next"></script>`
- In-browser playground on [Codepen](https://codepen.io/yyx990803/pen/OJNoaZL)
- Scaffold via [Vite](https://github.com/vitejs/vite):

  ```bash
  npm init vite-app hello-vue3 # OR yarn create vite-app hello-vue3
  ```

- Scaffold via [vue-cli](https://cli.vuejs.org/):

  ```bash
  npm install -g @vue/cli # OR yarn global add @vue/cli
  vue create hello-vue3
  # select vue 3 preset
  ```

## Changes from Vue 2

Please consult the [Migration Guide](https://v3.vuejs.org/guide/migration/introduction.html).

- Note: IE11 support is still pending.

## Supporting Libraries

All of our official libraries and tools now support Vue 3, but most of them are still in beta status and distributed under the `next` dist tag on NPM. **We are planning to stabilize and switch all projects to use the `latest` dist tag by end of 2020.**

### Vue CLI

As of v4.5.0, `vue-cli` now provides built-in option to choose Vue 3 preset when creating a new project. You can upgrade `vue-cli` and run `vue create` to create a Vue 3 project today.

### Vue Router

Vue Router 4.0 provides Vue 3 support and has a number of breaking changes of its own. Check out its [Migration Guide](https://next.router.vuejs.org/guide/migration/) for full details.

- [GitHub](https://github.com/vuejs/vue-router-next)
- [RFCs](https://github.com/vuejs/rfcs/pulls?q=is%3Apr+is%3Amerged+label%3Arouter)

### Vuex

Vuex 4.0 provides Vue 3 support with largely the same API as 3.x. The only breaking change is [how the plugin is installed](https://github.com/vuejs/vuex/tree/4.0#breaking-changes).

- [GitHub](https://github.com/vuejs/vuex/tree/4.0)

### Devtools Extension

We are working on a new version of the Devtools with a new UI and refactored internals to support multiple Vue versions. The new version is currently in beta and only supports Vue 3 (for now). Vuex and Router integration is also work in progress.

- For Chrome: [Install from Chrome web store](https://chrome.google.com/webstore/detail/vuejs-devtools/ljjemllljcmogpfapbkkighbhhppjdbg?hl=en)

  - Note: the beta channel may conflict with the stable version of devtools so you may need to temporarily disable the stable version for the beta channel to work properly.

- For Firefox: [Download the signed extension](https://github.com/vuejs/vue-devtools/releases/tag/v6.0.0-beta.2) (`.xpi` file under Assets)

### IDE Support

It is recommended to use [VSCode](https://code.visualstudio.com/) with our official extension [Vetur](https://marketplace.visualstudio.com/items?itemName=octref.vetur), which provides comprehensive IDE support for Vue 3.
