Who want write something like this: Ti.Network.createHTTPClient()
?
With this module, you can use any shortcut you have used with jQuery.
var _ = require( "underscore" ),
$ = require( "util" );
$.ajax( /* params */ )
There are shorthands of course:
$.getJSON
$.post
$.get
Underscore.js http://documentcloud.github.com/underscore/
There are some unit tests. Unfortunately for Appcelerator Titanium, there aren't any officially supported test framework.
TODO
This is one of my projects, to port Backbonejs into Appcelerator.
