Now, we should modify BaseController.php from the Frontend module to extend the core module and to assign categories globally to our views upon each request. Open modules/Frontend/Controllers/BaseController.php, clear its contents, and append this code:

<?php
namespace App\Frontend\Controllers;

class BaseController extends \App\Core\Controllers\BaseController
{
    public function afterExecuteRoute()
    {
        $this->view->categories = $this->apiGet('categories');
    }
}

We don't actually have a home page (but we can add one anytime we want), so we are going to forward the request to ArticlesController. Open modules/Frontend/Controllers/IndexController.php, remove indexAction(), and append the following code:

  public function indexAction()
  {
      return $this->dispatcher->forward([
    'controller' => 'article',
    'action' => 'list'
      ]);
  }

The last step is to create the listAction() method and the view for the articles....
