State Mixin

The State Mixin will be deprecated, we recommend you use containers instead.

We found that there was a lot of boilerplate code in React components to start listening to stores and get their states. The State mixin helps to reduce the amount of code you have to write.

Firstly, it automatically adds change listeners to stores you want to listen to, as well as disposing of those listeners when the component unmounts.

It also introduces a new function getState, which returns the state of the component. It will be called just before the initial render of the component and whenever a store updates.

var UserState = Marty.createStateMixin({
  listenTo: ['userStore', 'friendsStore'],
  getState: function () {
    return {

var Users = React.createClass({
  mixins: [UserState],
  render: function () {
    return (<ul>
      { (user) {
        return <li>{}</li>;
