Exposing a Global Browserify module

browserify-global-module.js

/**
 * NOTE: I am new at this and probably miss something obvious :-)
 *
 * What I'd like to do is the following:
 * - Using the Revealing Module Pattern..
 * - .. combined with Browserified modules..
 * - .. to expose (not export) `myModule` globally in main.js (-> bundle.js)..
 * - .. and to use it in the browser e.g: myModule.init()
 *
 * How do I (best) end up with a global `myModule`??
 */
 
 // E.g. take the following
 
/**
 * main.js
 */

var util = require('someUtil');
var libb = require('someLib');

// Revealing Module
var myModule = (function( win, doc, undefined ){
  'use strict';
  // 'Private' stuffz
  var _private = {
    init: function(){
      console.log('_private.init()');
    }
  };

  // 'Public' stuffz
  var _public = {
    init: _private.init
  };

  return _public;

})( window, document );


// NOW: when I do the following (in e.g. Devtools)
// > console.log(myModule);
// > uncaught ReferenceError: myModule is not defined

// So how should I expose `myModule` as a global?
