A Transmit class, that takes a Store and a Component, wraps the component in an anonymous wrapper and injects the store's data

Transmit.js

import React from "react";
import Store from "./Store.js";
import assign from "object-assign";

class Transmit {
  constructor(Component, Storage) {
    const Container = React.createClass({
      displayName: Component.displayName + "Container",
      getInitialState() {
        return {
          data: Storage.get()
        };
      },
      componentDidMount() {
        Storage.addChangeListener(this._change);
      },
      componentWillUnmount() {
        Storage.removeChangeListener(this._change);
      },
      _change() {
        this.setState({
          data: Storage.get()
        });
      },
      render() {
        const props = this.props || {};
        const state = this.state || {};

        return React.createElement(
          Component,
          assign({}, props, state)
        );
      }
    });

    return Container;
  }
}

export default Transmit;
