Create a dispatcher factory resolving callables

This package provides an Ellipse\Dispatcher\CallableResolver class implementing Ellipse\DispatcherFactoryInterface which allows to decorate any other object implementing this interface.

Once decorated, the resulting dispatcher factory can be used to produce instances of Ellipse\Dispatcher by resolving callables as Ellipse\Middleware\CallableMiddleware from the ellipse/middleware-callable package or as Ellipse\Handlers\CallableRequestHandler from the ellipse/handlers-callable package.

CallableMiddleware and CallableRequestHandler logic is described on the ellipse/middleware-callable and ellipse/handlers-callable documentation pages.


namespace App;

use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Server\RequestHandlerInterface;

use Ellipse\DispatcherFactory;
use Ellipse\Dispatcher\CallableResolver;

// Decorate a DispatcherFactoryInterface implementation with a CallableResolver.
$factory = new CallableResolver(new DispatcherFactory);

// This callable acts as a middleware.
$middleware = function (ServerRequestInterface $request, RequestHandlerInterface $handler) {

    // ...


// This callable acts as a request handler.
$handler = function (ServerRequestInterface $request) {

    // ...


// A dispatcher using both callables and Psr-15 instances can now be created.
$dispatcher = $factory($handler, [$middleware, new SomeMiddleware]);
