You can install XState from NPM or Yarn, or you can embed the <script> directly from a CDN.

Package Manager

npm install xstate@latest --save
# or:
yarn add xstate@latest --save


You can include XState directly from the unpkg CDN:

<script src=""></script>

The variable XState will be available globally, which will give you access to the top-level exports.

const { Machine, actions, interpret } = XState; // global variable: window.XState

const lightMachine = Machine({
  // ...

const lightService = interpret(lightMachine);
