Lumen/Laravel - use custom router - laravel

Question

Is there any out of the box solution without changing core to add custom router in to laravel or lumen. I already know that lumen is using different router from laravel, so I am wondering is there any possibility builded in core to change router?

Answer 1

I had the same question today. After some research I found a solution which will impact the core classes minimal.
Note: The following description is based on Lumen 6.2.
Before you start; think about a proper solution, using a middleware.
Because of the nature of this framework, there is no way to use a custom Router without extending core classes and modifying the bootstrap.
Follow these steps to your custom Router:
Hacky solution
1. Create your custom Router.
Hint: In this example App will be the root namespace of the Lumen project.
<?php
namespace App\Routing;
class Router extends \Laravel\Lumen\Routing\Router
{
public function __construct($app)
{
dd('This is my custom router!');
parent::__construct($app);
}
}
There is no Interface or similar, so you have to extend the existing Router. In this case, just a constructor containing a dd() to demonstrate, if the new Routerist going to be used.
2. Extend the Application
The regular Router will be initialized without any bindings or depentency injection in a method call inside of Application::__construct. Therefore you cannot overwirte the class binding for it. We have to modify this initialization proccess. Luckily Lumen is using a method just for the router initialization.
<?php
namespace App;
use App\Routing\Router;
class Application extends \Laravel\Lumen\Application
{
public function bootstrapRouter()
{
$this->router = new Router($this);
}
}
3. Tell Lumen to use our Application
The instance of Applicationis created relativley close at the top of our bootstrap/app.php.
Find the code block looking like
$app = new Laravel\Lumen\Application(
dirname(__DIR__)
);
and change it to
$app = new App\Application(
dirname(__DIR__)
);
Proper solution
The $router property of Application is a public property. You can simply assign an instance of your custom Router to it.
After the instantiation of Application in your bootstrap/app.php place a
$app->router = new \App\Routing\Router;
done.
