This file starts the application like you would normally do in the client side. It is wrapped by the Provider component and passes to it the appData received from the index.ejs file.

client.jsx

window['MY_APP'] = window['MY_APP'] || (() => {
  return {
    initialize: (config) => {
      ReactDOM.render(
        <Provider appData={config.appData}>
          <Router history={browserHistory}>
            { routes }
          </Router>
        </Provider>,
        document.getElementById('root')
      );
    }
  };
})();
