Lumen route param to object middleware

Lumen middleware to use Route parameters as objects (like Laravel does)

This is a route middleware.

Installation:

1. composer require spinyman/lumen-route-param-to-object-middleware
2. Register middleware in ./bootstrap/app.php:

   $app->routeMiddleware(
       [
           'param2object' => \SpinyMan\LumenRouteParamToObject\Middleware\RouteParamToObject::class,
       ]
   );

3. Add it to any group route (ex.: RouteServiceProvider):

   $this->router->group(
       [
           'middleware' => 'param2object',
       ],
       static function (\Laravel\Lumen\Routing\Router $router) {
           // your code goes here
       }
   );

Examples

Eloquent:

//router
$this->router->group(
    [
        'middleware' => 'param2object',
    ],
    static function (\Laravel\Lumen\Routing\Router $router) {
        $this->router->get(
            '/books/{book}',
            'BookController@show'
        );
    }
)

class Book extends \Illuminate\Database\Eloquent\Model
{
    protected $table = 'books';
}

class BookController extends \Laravel\Lumen\Routing\Controller {
    public function show(\Laravel\Lumen\Http\Request $request, Book $book)
    {
        $bookId = $book->getKey();
        // your code goes here
    }
}

Simple class:

//router
$this->router->group(
    [
        'middleware' => 'param2object',
    ],
    static function (\Laravel\Lumen\Routing\Router $router) {
        $this->router->get(
            '/namer/{namer}',
            'NamerController@run'
        );
    }
)

// Namer class
class Namer
{
    private $name;
    
    public function __construct(string $name)
    {
        $this->name = $name;
    }
    
    public  function getName(): string
    {
        return ucfirst(
            strtolower($this->name)
        );
    }
} 

class NamerController extends \Laravel\Lumen\Routing\Controller
{
    public function run(\Laravel\Lumen\Http\Request $request, Namer $namer)
    {
        return $namer->getName();
    }
}
