A simple mixin for getting state from Flux stores in a React view. An example of how simple it can be. You're probably better off using a full library though...

StoreWatchMixin.js

"use strict";
var shallowEqual = require('shallow-equals');

// Create a mixin for a component that depends on a store(s) for
// state. Component should define getStateFromStores
module.exports = function StoreWatchMixin(...stores) {
  return {
    componentDidMount () {
      stores.forEach((store) => {
        store.addListener('change', this.onStoreChange);
      });
    },

    componentWillMount () {
      this.setState(this.getStateFromStores(this.props));
    },

    componentWillUnmount () {
      stores.forEach((store) => {
        store.removeListener('change', this.onStoreChange);
      });
    },

    componentWillReceiveProps (nextProps) {
      if (!shallowEqual(nextProps, this.props)) {
        this.setState(this.getStateFromStores(nextProps));
      }
    },

    onStoreChange () {
      this.setState(this.getStateFromStores(this.props));
    }
  };
};
