Factory Function File Pattern

You know, I’m not very big fan of factory functions, nevertheless, I’m aware of the fact that they may be necessary in some situations. Here is the file pattern that works (briefly tested).

Keep each factory function in a separate file name of which should be Namespace.Factory.functionName.js

// vim: ts=4:sw=4:nu:fdc=4:nospell
/*global Ext, MyNamespace */
/**
 * @class MyNamespace.Factory
 *

// create namespace
Ext.ns('MyNamespace.Factory');
 
/**

MyNamespace.Factory.myPanel = function(config) {
 
	// pre-instantiation code
	var defaults = {
		// put your defaults here
		// but avoid id, el, contentEl, renderTo, applyTo, or similar
	}; // eo defaults object
 
	// create config object
	var cfg = Ext.apply({}, config, defaults);
 
	// instantiate
	var cmp = new Ext.Panel(cfg);
 
	// post-instantiation code
 
	// return the created component
	return cmp;
 
} // eo function MyNamespace.Factory.myPanel
 
// eof
