This article shows how to use Ajax techniques to make web apps with REST APIs.

CrackAJAX is based around the concept of an AjaxPage, an HTML page that is "ajaxified." In its current incarnation, you can write the HTML code right in the docstring, or pass it a callable template rendering method. You extend the AjaxPage class, add your markup, and then add special methods. These special methods are decorated as either @clientside or @serverside, depending on where you want them to be run. @clientside methods translate the Python source code of the method to client-side JavaScript, and @serverside methods automatically generate an XML-RPC call to the server. You can call these seamlessly from your DHTML handlers, just like regular JavaScript.
