Infrastructure for use middleware in applications
=================================================

[](#infrastructure-for-use-middleware-in-applications)

[![Request delegate pipeline](request-delegate-pipeline.png)](request-delegate-pipeline.png)

Installation
------------

[](#installation)

Pretty simple with [Composer](http://packagist.org), run:

```
composer require gpslab/middleware
```

Middleware chain
----------------

[](#middleware-chain)

`MiddlewareChain` contains a middlewares (`Middleware`) and sequentially apply them to the message by chain.

There are 3 implementations of the chain, but you can make your own.

- `DirectBindingMiddlewareChain` - direct binding;
- `ContainerMiddlewareChain` - [PSR-11](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-11-container.md) container;
- `SymfonyContainerMiddlewareChain` - Symfony container *(Symfony 3.3 [implements](http://symfony.com/blog/new-in-symfony-3-3-psr-11-containers) a [PSR-11](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-11-container.md))*.

Handle command (CQRS)
---------------------

[](#handle-command-cqrs)

Example usage middleware for handle Commands in [CQRS](https://github.com/gpslab/cqrs).

```
// middleware chain
$chain = new DirectBindingMiddlewareChain();

// add logger middleware
$chain->append(new LoggerMiddleware($logger));
// add validator middleware
$chain->append(new ValidatorMiddleware($validator));
// add middleware for handle command from origin command bus
$chain->append(new CommandMiddleware($command_bus));

// configure command bus
$bus = new MiddlewareCommandBus($chain);

// handle command
try {
    $bus->handle($my_command);
} catch(InvalidMessageException $e) {
    // show validation errors
    var_dump($e->getMessages());
}
```

Handle query (CQRS)
-------------------

[](#handle-query-cqrs)

Example usage middleware for handle Queries in [CQRS](https://github.com/gpslab/cqrs).

```
// middleware chain
$chain = new DirectBindingMiddlewareChain();

// add logger middleware
$chain->append(new LoggerMiddleware($logger));
// add validator middleware
$chain->append(new ValidatorMiddleware($validator));
// add middleware for handle query from origin query bus
$chain->append(new QueryMiddleware($query_bus));

// configure query bus
$bus = new MiddlewareQueryBus($chain);

// handle query
try {
    $bus->handle($my_query);
} catch (InvalidMessageException $e) {
    // show validation errors
    var_dump($e->getMessages());
}
```

Handle Domain event
-------------------

[](#handle-domain-event)

Example usage middleware for handle [domain events](https://github.com/gpslab/domain-event).

```
// middleware chain
$chain = new DirectBindingMiddlewareChain();

// add logger middleware
$chain->append(new LoggerMiddleware($logger));
// add middleware for handle event from origin domain event bus
$chain->append(new DomainEventMiddleware($domain_event_bus));

// configure domain event bus
$bus = new MiddlewareDomainEventBus($chain);

// publish domain event
$bus->publish($my_event);
```
