Car

Car is a PHP implementation of the Command Bus pattern for DDD., _(*1)

, _(*2)

Disclaimer

This is a very basic and simple implementation. It has to grow up :), _(*3)

Installation

composer require maximecolin/car

Purpose

The aim of the command bus pattern is to isolate your domain code in atomic, testable and reusable classes and to execute them through a dedicated service., _(*4)

Usage

A command is an order. It can contains data you need. Attributes can be set on construct, fill through a form, set by other services, ..., _(*5)

class CreateArticleCommand implements CommandInterface
{
    public $title;
    public $content;

    public function __construct($title, $content)
    {
        $this->title   = $title;
        $this->content = $content;
    }
}

Create an handler which will process your command., _(*6)

class CreateCommandHandler implements CommandHandlerInterface
{
    public function handle(CommandInterface $command)
    {
        // Place here you domain code which create an article ...
    }
}

// Usually, have a service to get the bus
$bus = new CommandBus();
$bus->addResolver(new ClassNameResolver());

$command = new CreateArticleCommand('My article name', 'My article content');

$bus->execute($command);
