# Simple Command Bus for PHP 8
[](https://github.com/ericksonreyes/command-bus/actions/workflows/merge.yaml)
Nothing fancy. I just created my command bus that I've been copy-pasting over and over again. I usually move most of
the business or application logic away from framework controllers (MVC) and put it into commands and handlers.
But I don't want to couple the command handler with the framework controller. I want to be able to assign and switch
them via a dependency injection library.
## Installation
```shell
composer require ericksonreyes/command-bus
```
### Example (Lumen Framework + Symfony Dependency Injection)
Symfony Service Container Configuration
```yaml
services:
uuid_generator:
class: App\Services\UuidGenerator
user_repository:
class: App\Repositories\UserRepository
user_registration_service:
class: Application\Users\Service\UserRegistrationService
arguments:
- '@user_repository'
```
Lumen Controller
```php
namespace App\Http\Controllers;
use App\Repository\UserRepository;
use Illuminate\Support\Facades\URL;
use Illuminate\Http\Request;
use Illuminate\Http\Response;
use Illuminate\Routing\Controller as BaseController;
use Symfony\Component\DependencyInjection\ContainerInterface;
use Application\Users\UseCase\RegisterUser;
/**
* Class UserRegistrationController
* @package App\Http\Controllers
*/
class UserRegistrationController extends BaseController {
/**
* @param \Symfony\Component\DependencyInjection\ContainerInterface $container
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(
ContainerInterface $container,
Request $request
): Response {
try {
$url = URL::current();
$id = $uuidGenerator->generate(prefix: 'user-');
$uuidGenerator = $container->get('uuid_generator');
$handler = $container->get('user_registration_service');
$command = new RegisterUser(
$id,
$request->get('email'),
$request->get('password'),
$request->get('password_confirmation')
);
$handler->handleThis($command);
return \response([
'_embedded' => [
'_links' => [
'self' => [
'href' => url("{$url}/{$id}")
]
],
'id' => $id
]
], 201);
}
catch (\Exception $exception) {
$httpCode = 500;
if ($exception->getCode() >= 400 && $exception->getCode() < 600) {
$httpCode =$exception->getCode();
}
return \response([
'_error' => [
'code' => get_class($exception),
'message' => $exception->getMessage()
]
], $httpCode);
}
}
}
```
