Installation
Direct Download / CDN
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@2.0.0.
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 --save
Yarn
yarn add vuex
When used with a module system, you must explicitly install Vuex via Vue.use():
import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)
You don't need to do this when using global script tags.
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
npm install
npm run build
