Helthe CQRS Component

Helthe CQRS

Helthe CQRS is a small library implementing command-query separation. It's based on the refactored version of LiteCQRS and the work of Mark Nijhof for his CQRS book., _(*1)

Currently, the library only implements command handling using a command bus for communication., _(*2)

use Helthe\Component\CQRS\Command\CommandInterface;
use Helthe\Component\CQRS\CommandHandler\CommandHandlerInterface;
use Helthe\Component\CQRS\CommandHandler\MemoryCommandHandlerLocator;

/* @var CommandInterface */
$command = new Command()
/* @var CommandHandlerInterface */
$handler = new CommandHandler()

$locator = new MemoryCommandHandlerLocator();
$locator->register(get_class($command), $handler);

$bus = new SequentialCommandBus($locator);

$bus->dispatch($command);
