use Psr\Http\Message\ResponseInterface;

/**

* @var Psr\Http\Server\RequestHandlerInterface $handler
* @var Psr\Http\Server\MiddlewareInterface $siteMiddleware
* @var Psr\Http\Server\MiddlewareInterface $userMiddleware
*/

// Basic usage

$runner = new ServerRequestRunner();
$runner->run($request, $handler);

// Using `MiddlewarePipeline`

$pipeline = new MiddlewarePipeline();
$pipeline->pipe($siteMiddleware);
$pipeline->pipe($userMiddleware, '/user');

$runner = new ServerRequestRunner($pipeline);
$runner->run($request, $handler);

// Using `MiddlewareResolver`

$resolver = new MiddlewareResolver();
$handlerMiddleware = $resolver->resolve(function (): ResponseInterface {
$response = new HttpSoft\Message\Response();
$response->getBody()->write('Hello world!');
return $response;
});

$pipeline = new MiddlewarePipeline();
$pipeline->pipe($siteMiddleware);
$pipeline->pipe($userMiddleware, '/user');
$pipeline->pipe($handlerMiddleware);

$runner = new ServerRequestRunner($pipeline);
$runner->run($request); // Output result: 'Hello world!'
```
