# Mopidy.js JavaScript library We've made a JavaScript library, Mopidy.js, which wraps the [WebSocket API](http.md#websocket-api) and gets you quickly started with working on your client instead of figuring out how to communicate with Mopidy. This library is used as the foundation of most [Mopidy web clients](https://mopidy.com/ext/). See the [Mopidy.js project](https://github.com/mopidy/mopidy.js) for detailed usage documentation and demo applications built using Mopidy.js.
