Im having trouble understanding how to access the instance of Slim when a route is in a seperate class than index.php

This was a tough one. @mgansler answer was really helpful, but in his answer he passed a database connection, and not exactly $app inside the controller

Following the same idea it is possible to send $app though.

First inside your dependencies.php you need to grab the $app and throw it in a container to inject it to the Controller later.

$container['slim'] = function ($c) {
   global $app;
   return $app;
};

Then you got to inject it:

// Generic Controller
$container['App\Controllers\_Controller'] = function ($c) {
    return new _Controller($c->get('slim'));
};

Now on your controller.php:

private $slim;

/**
     * @param \Psr\Log\LoggerInterface       $logger
     * @param \App\DataAccess                $dataaccess
     * @param \App\$app                      $slim
     */
    public function __construct(LoggerInterface $logger, _DataAccess $dataaccess, $slim)
    {       
        $this->logger = $logger;
        $this->dataaccess = $dataaccess;
        $this->slim = $slim;
    }

Now you just got call it like this:

$this->slim->doSomething();
