Nooku Framework
The extension API that speaks for itself !
Joomladay NL, June 2009 - Nieuwegein

Technology, features, experience !
At some point, to stay viable, content management systems
require a quantum evolution that takes them beyond
technology and features and on to the satisfaction of a
customer experience. That’s what we are trying to do with
Nooku.

What is it ?
Rapid extension development framework for Joomla.
•Version 0.7.0
• GPL v 2.0 license
• Non-commercial
• Joomla 1.5 only
• Installs as a plugin
• 30k lines of code
• Can work standalone
http:///www.nooku.org 1
6

Why a new framework ?
1. Developing for Joomla 1.5 :
• takes too much time
• too much repeated tasks
• resulting extensions are inflexible
• PHP4
2. Existing framework don’t integrate easily with Joomla

How it used to be ...
...
class WeblinksController extends JController
// Checkout the weblink
{ $model = $this->getModel('weblink');
function __construct($config = array()) $model->checkout();
{ } break;
parent::__construct($config); case 'edit' :
{
// Register Extra tasks JRequest::setVar( 'hidemainmenu', 1 );
$this->registerTask( 'add', 'display' ); JRequest::setVar( 'layout', 'form' );
$this->registerTask( 'edit', 'display' ); JRequest::setVar( 'view' , 'weblink');
JRequest::setVar( 'edit', true );
}
// Checkout the weblink
function display( ) $model = $this->getModel('weblink');
{ $model->checkout();
switch($this->getTask()) } break;
{ }
case 'add' :
{
JRequest::setVar( 'hidemainmenu', 1 );
JRequest::setVar( 'layout', 'form' );
JRequest::setVar( 'view' , 'weblink');
JRequest::setVar( 'edit', false );

How it should be ...
class WeblinksControllerWeblinks extends KControllerForm
{
//do nothing
}
class WeblinksModelWeblinks extends KModelTable
{
//do nothing
}
class WeblinksViewWeblinks extends KViewHtml
{
//do nothing
}
That’s all you need for a working MVC extensions !

House Rules !
• Use existing Design Pattern
Don’t reinvent the wheel - just make it roll smoother
• Make all code reusable
Don’t repeat yourself - and don’t repeat anyone else either
• Extreme flexibility
Every object, and every part of the code must be extensible and replaceable.
Ability to hook into any controller, database or application action
• An API is like a User Interface
Learn once, apply everywhere
KISS : keep it sexy and simple
• Convention over configuration
• Scaffolding is a fancy word for copy/paste
