Simple inheritance with CommonJS Modules and Titanium

dashboardController.js

/**
 * Dashboard controller
 */

// Private
var api = require('parentcontroller');

api.load = function() {
	Ti.API.info('Child load method fired');
};

api.getWindow = function() {
	Ti.API.info('Child getWindow method fired');
};

// Public
exports.boot = function(_params) {
	// expose the public api object
	return api;
};

implementation.js

// Create the module
var controllerModule = require('dashboardController').boot(_params);
// Test to see if the parent controller's load method or dashboardController method fires
controllerModule.load();

parentcontroller.js

/**
 * Core Controller / Parent Object
 */
// Private
 Ti.API.info('Parent controller constructor fired');

// Public
exports.load = function() {
	Ti.API.info('Parent load method just fired');
};
exports.build = function() {
	Ti.API.info('Parent build method just fired');
};
exports.getWindow = function() {
	Ti.API.info('Parent getWindow method just fired');
};

This is a really easy pattern to use and requires no extra JS logic or trickery to inherit things, so it's very fast. The downside to this is all overridden methods and properties in the sub controller are gone forever - so you can't use a parent controller method inside the child controller after you've overridden it.
