Direct Download / CDN 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

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 install vuex@next --save


yarn add vuex@next --save


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=""></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 node_modules/vuex
cd node_modules/vuex
yarn build
