Node-Webkit start function in different window

One solution I've found to be pretty effective is attaching pub/sub functionality to the globalvariable. The setup I've used so far is jQuery-based, though it could also be constructed without. First it is initialized using a variant of this code:

    var messages = messages || {};
    global.Message = global.Message || function( id ) {
      var callbacks, method,
      message = id && messages[ id ];
      if ( !message ) {
        callbacks = jQuery.Callbacks();
        message = {
          publish: callbacks.fire,
          subscribe: callbacks.add,
          unsubscribe: callbacks.remove
        };
        if ( id ) {
        messages[ id ] = message;
        }
      }
      return message;
    };

Then anywhere between the windows events can be published and subscribed to using the following pattern. One window can publish the data:

global.Message("someButtonClicked").publish(data);

Then the other can listen for it.

global.Message("someButtonClicked").subscribe(onButtonClicked);

function onButtonClicked(data) {
  console.log(data);
};
