Vue 3 Tutorial: Lesson 1 – Installation


Release Notes
Latest beta version: 3.0.0-rc.10 (2020-09-03)

Detailed release notes for each version are available on GitHub

CDN
For prototyping or learning purposes, you can use the latest version with:

<script src="https://unpkg.com/vue@next"></script>

For production, we recommend linking to a specific version number and build to avoid unexpected breakage from newer versions:

<script src="https://unpkg.com/vue@3.0.0-rc.10"></script>

NPM
NPM is the recommended installation method when building large scale applications with Vue. It pairs nicely with module bundlers such as Webpack or Browserify. Vue also provides accompanying tools for authoring Single File Components.

# latest stable
$ npm install vue@next

CLI
Vue provides an official CLI for quickly scaffolding ambitious Single Page Applications. It provides batteries-included build setups for a modern frontend workflow. It takes only a few minutes to get up and running with hot-reload, lint-on-save, and production-ready builds. See the Vue CLI docs for more details.

For Vue 3, you should use Vue CLI v4.5 available on npm as @vue/cli@next.

Upgrade CLI
To upgrade CLI, you need to reinstall the latest version of @vue/cli globally:

npm install -g @vue/cli@next

Result:

D:\TypeScript\Vue>npm install -g @vue/cli@next
