This Mohammad Gufran's blog post entitled "DRIVE YOUR APPLICATION WITH ILLUMINATE ROUTER" could give you a preview of what could be done.
To sum up:
- Initialize your project using Composer.
- Define the dependencies, namely: "illuminate/routing": "4.1.*" and "illuminate/events": "4.1.*".
- Create the "index.php" and "routes.php" files as suggested.
Et voilà!
Excerpt from routes.php:
$app['router']->get('/', function() {
// Because 'Hello, World!' is too mainstream
return 'Are you looking for me ?';
});
