CQRS PHP

CQRS in PHP is a simple project (a folder structure) for your project build with Domain Driven Design.

Installation

The recomanded way to install CQRS in PHP is through Composer:

{
    "require": {
        "black/cqrs-php": "@stable"
    }
}

Protip: You should browse the black/cqrs-php page to choose a stable version to use, avoid the @stable meta constraint.

Why?

I want to use a very basic library for CQRS without Event Sourcing. There is one Bus, register your handler with the related command and go for it!

Usage

1 - Create a Command implementing Black\DDD\CQRSinPHP\Infrastructure\CQRS\Command
2 - Create an Handler implementing Black\DDD\CQRSinPHP\Infrastructure\CQRS\CommandHandler
3 - Register the Handler/Command to the Bus

<?php

$bus = new Black\DDD\CQRSinPHP\Infrastructure\CQRS\Bus;
$handler = new My\Handler();

$bus->register('My\Command', $handler);

// Do stuff
$command = new My\Command($foo, $bar);
$bus->handle($command);

SymfonyBundle

Register the bundle:

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...
        new Black\Bundle\CQRSBundle\BlackCQRSBundle(),
    );
}

Declare your handler as a service and add this tag:

services:
    my.handler:
        class: 'My\Handler'
        tags:
            - { name: black_cqrs.handler, command: "My\Command" }

And use it:

<?php

public function __construct(Black\DDD\CQRSinPHP\Infrastructure\CQRS\Bus $bus)
{
    $this->bus = $bus;
}

public function myFunction($foo, $bar)
{
    $command = new My\Command($foo, $bar);
    $this->bus->handle($command);
}
