Drop-In Sub-Application Architecture for Backbone.Marionette

In my latest project, I had to develop a pattern for a Backbone.Marionette application framework that would be easily extensible with "drop-in" sub-applications that should require minimal effort to add to the master application.

This is what I came up with. It requires one additional custom component - Marionette.SubAppRouter (also included in the gist) to provide relative routes for sub applications, but other than that requires no logic not already provided by Marionette.

I should note that we are using requireJS for dependency loading rather than Marionette's module system.

Hi Jeremy!

Thank you for this awesome implementation! Helped me out with my own app!

Only one question about the vent.super.js ... when I try to add the bus messaging system to my app, always the following error is shown:

Uncaught TypeError: Cannot call method 'extend' of undefined vent.super.js:26

Seems that Marionette.EventAggregator.extend({ wont work ... has Marionette maybe been updated?

I've updated the gist. The only change I made was to the SuperVent.js file - immediately before trying to extend the Marionette.EventAggregator class, I just added the line

Marionette.EventAggregator.extend = Backbone.Model.extend;

Also I should mention that this code was written for Marionette while it was in a very early RC state, and I know things like EventBinder have been removed or replaced with Backbone's new event system, so it may require a little tweaking.

Hi,

Should line 21 in Application.root.js be
rootApp.subApps = subApps;
instead of
rootApps.subApps = subApps;

It should be rootApp instead of rootApps?

Sure enough. Good catch; I've updated the gist.
