[](#helthe-cqrs--)

Helthe CQRS is a small library implementing [command-query separation](http://en.wikipedia.org/wiki/Command%E2%80%93query_separation). It's based on the refactored version of [LiteCQRS](https://github.com/beberlei/litecqrs-php) and the work of [Mark Nijhof](https://github.com/MarkNijhof/Fohjin)for his [CQRS book](https://leanpub.com/cqrs).

Currently, the library only implements command handling using a command bus for communication.

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);
```
