README

A basic PSR compliant middleware dispatcher.

Overview

The middleware-dispatcher library provides a simple and extensible middleware dispatcher that complies with the PSR-15 standards. It allows you to handle HTTP server requests by processing a stack of middlewares.

Features

• PSR-15 compliant
• Simple and easy-to-use API
• Supports any PSR-15 compatible middlewares
• Handles exceptions and invalid middlewares gracefully

Installation

To install the middleware-dispatcher library, use Composer:

composer require alanvdb/middleware-dispatcher

Usage

Here is an example of how to use the middleware-dispatcher:

<?php

require 'vendor/autoload.php';

use AlanVdb\Dispatcher\Dispatcher;
use AlanVdb\Dispatcher\Factory\DispatcherFactory;
use Psr\Http\Server\RequestHandlerInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Server\MiddlewareInterface;
use GuzzleHttp\Psr7\ServerRequest;
use GuzzleHttp\Psr7\Response;

class ExampleMiddleware implements MiddlewareInterface
{
    public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
    {
        // Add your middleware logic here
        return $handler->handle($request);
    }
}

$middlewares = [new ExampleMiddleware()];
$factory = new DispatcherFactory();
$dispatcher = $factory->createDispatcher($middlewares);

$request = new ServerRequest('GET', 'https://api.example.com/data');
$response = $dispatcher->handle($request);

echo $response->getBody();
