Closure Handler Middleware

PSR-15 compatible HTTP middleware which can utilize closure type request handlers.

If you don't want to bother about those ugly HTTP controllers and love simplicity, this middleware is your best friend.

Requirements

• PHP >=8.0

Usage

$request = $serverRequestFactory
    ->createServerRequest('GET', '/')
    ->withAttribute('__handler', fn() => 'hello world!');

$middleware = new ClosureHandler($responseFactory, $streamFactory);

$response = $middleware->process($request, $nextHandler);

echo $response->getBody(); // Will print "hello world!"

If no handler found in the request object, or handler is not closure, then the middleware passes the request to the next middleware in the row.

Name of the request attribute (__handler) can be changed by the watchRequestAttribute() method.
