README

RoadRunner is an open-source (MIT licensed) high-performance PHP application server, load balancer, and process manager. It supports running as a service with the ability to extend its functionality on a per-project basis.

RoadRunner includes PSR-7/PSR-17 compatible HTTP and HTTP/2 server and can be used to replace classic Nginx+FPM setup with much greater performance and flexibility.

Repository:

This repository contains the codebase PSR-7 PHP workers. Check spiral/roadrunner to get application server.

Installation:

To install application server and HTTP codebase:

$ composer require spiral/roadrunner-http nyholm/psr7

You can use the convenient installer to download the latest available compatible version of RoadRunner assembly:

$ composer require spiral/roadrunner-cli --dev

To download latest version of application server:

$ vendor/bin/rr get

You can use any PSR-17 compatible implementation.

Example:

To init abstract RoadRunner worker:

<?php

require __DIR__ . '/vendor/autoload.php';

use Nyholm\Psr7\Response;
use Nyholm\Psr7\Factory\Psr17Factory;

use Spiral\RoadRunner\Worker;
use Spiral\RoadRunner\Http\PSR7Worker;


// Create new RoadRunner worker from global environment
$worker = Worker::create();

// Create common PSR-17 HTTP factory
$factory = new Psr17Factory();

//
// Create PSR-7 worker and pass:
//  - RoadRunner worker
//  - PSR-17 ServerRequestFactory
//  - PSR-17 StreamFactory
//  - PSR-17 UploadFilesFactory
//
$psr7 = new PSR7Worker($worker, $factory, $factory, $factory);

while (true) {
    try {
        $request = $psr7->waitRequest();
    } catch (\Throwable $e) {
        // Although the PSR-17 specification clearly states that there can be
	// no exceptions when creating a request, however, some implementations
	// may violate this rule. Therefore, it is recommended to process the 
	// incoming request for errors.
        //
        // Send "Bad Request" response.
        $psr7->respond(new Response(400));
        continue;
    }

    try {
        // Here is where the call to your application code will be located. 
	// For example:
	//
        //  $response = $app->send($request);
        //
        // Reply by the 200 OK response
        $psr7->respond(new Response(200, [], 'Hello RoadRunner!'));
    } catch (\Throwable $e) {
        // In case of any exceptions in the application code, you should handle
	// them and inform the client about the presence of a server error.
	//
        // Reply by the 500 Internal Server Error response
        $psr7->respond(new Response(500, [], 'Something Went Wrong!'));
        
	// Additionally, we can inform the RoadRunner that the processing 
	// of the request failed.
        $worker->error((string)$e);
    }
}
