Usage
-----

[](#usage)

### Example

[](#example)

```
$handlers = [
    CreatePost::class => new CreatePostHandler($postRepository)
];

$middlewares = [
    new HandlerMiddleware(new MemoryLocator($handlers))
];

$commandBus = new MiddlewareBus(new MiddlewareStack($middlewares));

$message = new CreatePost('Post title', 'Post content');

$context = $commandBus->handle($message);
```

ProviderLocator:

```
$provider = new AnnotationProvider(__DIR__ . '/src');
if ($isProduction) {
    $provider = new CacheProvider(__DIR__ . '/data/handlers-cache.php', $provider);
}
$locator = new ProviderLocator($provider, new ContainerHandlerResolver($container));

return new MiddlewareBus(new MiddlewareStack([
    new HandlerMiddleware($locator),
]));
```

`ContainerHandlerResolver` may be used for [PSR-11 Container](https://github.com/php-fig/container) support.

### Context

[](#context)

The Message bus uses the immutable `Context` to transfer data through middlewares and return it to consumer.
