# Installation

# Direct Download / CDN

https://unpkg.com/vuex@4

Unpkg.com provides NPM-based CDN links. The above link will always point to the latest release on NPM. You can also use a specific version/tag via URLs like https://unpkg.com/vuex@4.0.0/dist/vuex.global.js.

Include vuex after Vue and it will install itself automatically:

<script src="/path/to/vue.js"></script>
<script src="/path/to/vuex.js"></script>

# NPM

npm install vuex@next --save

# Yarn

yarn add vuex@next --save

# Promise

Vuex requires Promise. If your supporting browsers do not implement Promise (e.g. IE), you can use a polyfill library, such as es6-promise.

You can include it via CDN:

<script src="https://cdn.jsdelivr.net/npm/es6-promise@4/dist/es6-promise.auto.js"></script>

Then window.Promise will be available automatically.

If you prefer using a package manager such as NPM or Yarn, install it with the following commands:

npm install es6-promise --save # NPM
yarn add es6-promise # Yarn

Furthermore, add the below line into anywhere in your code before using Vuex:

import 'es6-promise/auto'

# Dev Build

You will have to clone directly from GitHub and build vuex yourself if you want to use the latest dev build.

git clone https://github.com/vuejs/vuex.git node_modules/vuex
cd node_modules/vuex
yarn
yarn build
