Create require js plugin that listens for a backbone js global event

Is it possible to create a require js plugin that listens for a backbone global event and if that event is fired require js kicks in?

This is the scenario I would like to reproduce with require js http://jsfiddle.net/u2aej/

I'm thinking that this would look something like this.

require(['views/SubModule', 'editorLoaded!'], function (SubModule, editorLoaded) {
    //This function is called once the Editor is loaded.
    var view = new SubModule({el: '#sub-view' });
});

I'm not so familiar with require so maybe I'm totally wrong about this but I would like to here from you if you think this is a good idea and if it's possible?

It might be simpler to decouple the module from the event, and load the module explicitly using require().

Borrowing from this answer for Backbone global events - Backbone.js global events. Create the vent:

vent = _.extend({}, Backbone.Events);

vent.trigger("some:event");

Then load the module when the event is fired:

vent.on("some:event", function(){
    require(["myModule"], function(myModule) {
        myModule.doItsThing();
    });
});

But if you do want to write a plugin, then the best example to follow is probably - https://github.com/requirejs/domReady/blob/master/domReady.js.

Take a look at that, and replace with a version that calls the callbacks when a particular global event is fired, rather than when the DOM is ready.

However, I suspect that your dependency would look like this:

require(["globalEvent!editorLoaded"], function() { ... });

rather than this:

require(["editorLoaded!"], function() { ... });

(assuming your plugin is called globalEvent)

See the text plugin, https://github.com/requirejs/text, for how to pass parameters to the plugin.
