# vue-next [](https://www.npmjs.com/package/vue/v/next) [](https://circleci.com/gh/vuejs/vue-next) 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. - [](https://www.npmjs.com/package/vue-router/v/next) - [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). - [](https://www.npmjs.com/package/vuex/v/next) - [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. ### Other Projects | Project | NPM | Repo | | --------------------- | ----------------------------- | -------------------- | | @vue/babel-plugin-jsx | [![rc][jsx-badge]][jsx-npm] | [[GitHub][jsx-code]] | | eslint-plugin-vue | [![stable][epv-badge]][epv-npm] | [[GitHub][epv-code]] | | @vue/test-utils | [![beta][vtu-badge]][vtu-npm] | [[GitHub][vtu-code]] | | vue-class-component | [![beta][vcc-badge]][vcc-npm] | [[GitHub][vcc-code]] | | vue-loader | [![beta][vl-badge]][vl-npm] | [[GitHub][vl-code]] | | rollup-plugin-vue | [![beta][rpv-badge]][rpv-npm] | [[GitHub][rpv-code]] | [jsx-badge]: https://img.shields.io/npm/v/@vue/babel-plugin-jsx.svg [jsx-npm]: https://www.npmjs.com/package/@vue/babel-plugin-jsx [jsx-code]: https://github.com/vuejs/jsx-next [vd-badge]: https://img.shields.io/npm/v/@vue/devtools/beta.svg [vd-npm]: https://www.npmjs.com/package/@vue/devtools/v/beta [vd-code]: https://github.com/vuejs/vue-devtools/tree/next [epv-badge]: https://img.shields.io/npm/v/eslint-plugin-vue.svg [epv-npm]: https://www.npmjs.com/package/eslint-plugin-vue [epv-code]: https://github.com/vuejs/eslint-plugin-vue [vtu-badge]: https://img.shields.io/npm/v/@vue/test-utils/next.svg [vtu-npm]: https://www.npmjs.com/package/@vue/test-utils/v/next [vtu-code]: https://github.com/vuejs/vue-test-utils-next [jsx-badge]: https://img.shields.io/npm/v/@ant-design-vue/babel-plugin-jsx.svg [jsx-npm]: https://www.npmjs.com/package/@ant-design-vue/babel-plugin-jsx [jsx-code]: https://github.com/vueComponent/jsx [vcc-badge]: https://img.shields.io/npm/v/vue-class-component/next.svg [vcc-npm]: https://www.npmjs.com/package/vue-class-component/v/next [vcc-code]: https://github.com/vuejs/vue-class-component/tree/next [vl-badge]: https://img.shields.io/npm/v/vue-loader/next.svg [vl-npm]: https://www.npmjs.com/package/vue-loader/v/next [vl-code]: https://github.com/vuejs/vue-loader/tree/next [rpv-badge]: https://img.shields.io/npm/v/rollup-plugin-vue/next.svg [rpv-npm]: https://www.npmjs.com/package/rollup-plugin-vue/v/next [rpv-code]: https://github.com/vuejs/rollup-plugin-vue/tree/next
