README

This framework is based on concepts and components of other open source software, especially Zend Expressive, Zend Stratigillity, Recoil and React PHP.

Installation

Install a project using composer package manager:

composer create-project antidot-fw/reactive-starter dev
mv dev/.* dev/* ./ && rmdir dev
bin/console server:run

Open your browser localhost on port 5555 and you will see the DriftPHP Server up and running.

Config

Server Config

Default config

parameters:
    server:
      host: '0.0.0.0'
      port: '5555'
      max_concurrency: 100
      buffer_size: 4096
      workers: 4

Development Mode

To run it in dev mode you can run config:development-mode command

bin/console config:development-mode

Or you can do it by hand renaming from config/services/dependencies.dev.yaml.dist to config/services/dependencies.dev.yaml

mv config/services/dependencies.dev.yaml.dist config/services/dependencies.dev.yaml

Hot Code Reloading

composer require seregazhuk/php-watcher --dev

You can use Php whatcher with composer for more friendly development.

bin/console server:watch

Open another console and check the built-in Cli tool

bin/console

Async Usage

It allows executing promises inside PSR-15 and PSR-7 Middlewares and request handlers

PSR-15 Middleware

<?php
declare(strict_types = 1);

namespace App;

use Antidot\React\PromiseResponse;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Server\MiddlewareInterface;
use Psr\Http\Server\RequestHandlerInterface;

class SomeMiddleware implements MiddlewareInterface
{
    public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
    {
        return new PromiseResponse(
            resolve($request)->then(static fn(ServerrequestInsterface $request) => $handler->handle($request))
        );
    }
}

PSR-7 Request Handler

<?php
declare(strict_types = 1);

namespace App;

use Antidot\React\PromiseResponse;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Server\RequestHandlerInterface;

class SomeMiddleware implements RequestHandlerInterface
{
    public function process(ServerRequestInterface $request): ResponseInterface
    {
        return resolve($request)->then(
            function(ServerrequestInterface $request): ResponseInterface {
                return new Response('Hello World!!!');
            }
        );;
    }
}

Classic Usage

It allows executing classic PSR-15 middleware and request handler:

PSR-15 Middleware

<?php
declare(strict_types = 1);

namespace App;

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

class SomeMiddleware implements MiddlewareInterface
{
    public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
    {
        return $handler->handle($request);
    }
}

PSR-7 Request Handler

<?php
declare(strict_types = 1);

namespace App;

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

class SomeMiddleware implements RequestHandlerInterface
{
    public function process(ServerRequestInterface $request): ResponseInterface
    {
        return new Response('Hello World!!!');
    }
}
