Install

Usage
use Cormy\Server\Onion; use Psr\Http\Message\ResponseInterface; use Psr\Http\Message\ServerRequestInterface; // create the core of the onion, i.e. the innermost request handler $core = function (ServerRequestInterface $request):ResponseInterface { return new \Zend\Diactoros\Response(); }; // create some scales (aka middlewares) to wrap around the core $scales = []; $scales[] = function (ServerRequestInterface $request):\Generator { // delegate $request to the next request handler, i.e. $core $response = (yield $request); return $response->withHeader('content-type', 'application/json; charset=utf-8'); }; $scales[] = function (ServerRequestInterface $request):\Generator { // delegate $request to the next request handler, i.e. the middleware right above $response = (yield $request); return $response->withHeader('X-PoweredBy', 'Unicorns'); }; // create an onion style middleware stack $middlewareStack = new Onion($core, ...$scales); // and process an incoming server request $response = $middlewareStack(new \Zend\Diactoros\ServerRequest());
