Trying to optimize all files loaded by app.js to app.min.js

1. files

|- public/
|  |- js/
|  |  |- app/
|  |  |  |- interactions.js
|  |  |  |- main.js
|  |  |  |- students.js
|  |  |- lib/
|  |  |  |- console.log.js
|  |  |  |- jquery-1.9.1.js
|  |  |  |- no-js.js
|  |  |  |- require.js
|  |  |  |- typeahead.js
|  |  |- app.js

2. app.js

console.log('app.js loaded');

// Place third party dependencies in the lib folder
//
// Configure loading modules from the lib directory,
// except 'app' ones,
requirejs.config({
    "baseUrl": "js/lib",
    "paths"  : {
		"app"   : "../app",
		"jquery": "jquery-1.9.1"
	},
	"shim"   : {
		"no-js"    : ["jquery"],
		"typeahead": ["jquery"]
	}
});

// Load the main app module to start the app
requirejs(["app/main"]);

3. main.js

define(["console.log", "jquery", "no-js", "typeahead"], function($) {

    console.log('app/main.js loaded');

	require([
		"app/interactions",
		"app/students"
	]);

});

4. console

// It is working in the browser, because in each file I have a console.log()
// Console Output:
