ellipse/dispatcher-callable

Psr-15 middleware dispatcher factory resolving callables

Callable resolver

This package provides a factory decorator for objects implementing Ellipse\DispatcherFactoryInterface from ellipse/dispatcher package. It allows to produce instances of Ellipse\Dispatcher using callables as middleware and request handler., _(*1)

Require php >= 7.0, _(*2)

Installation composer require ellipse/dispatcher-callable, _(*3)

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., _(*5)

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., _(*6)

CallableMiddleware and CallableRequestHandler logic is described on the ellipse/middleware-callable and ellipse/handlers-callable documentation pages., _(*7)

<?php

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]);
