Broker is a dead simple [PSR-15][psr-15] middleware dispatcher. Broker implements

both `RequestHandlerInterface` and `MiddlewareInterface` for maximum flexibility.

[psr-15]: http://www.php-fig.org/psr/psr-15/

## Install

```

composer require northwoods/broker

```

## Usage

```php

use Acme\Middleware;

use Northwoods\Broker\Broker;

/** @var \Psr\Http\Message\ServerRequestInterface */

$request = /* any server request */;

// Use append() or prepend() to add middleware

$broker = new Broker();

$broker->append(new Middleware\ParseRequest());

$broker->prepend(new Middleware\CheckIp());

/** @var \Psr\Http\Message\ResponseInterface */

$response = $broker->handle($request);

```

### `append(...$middleware)`

Add one or more middleware to the end of the stack.

### `prepend(...$middleware)`

Add one or more middleware to be beginning of the stack.

### `handle($request)`

Dispatch the middleware stack as a request handler. If the end of the stack is

reached and no response has been generated, an `OutOfBoundsException` will

be thrown.

### `process($request, $handler)`

Dispatch the middleware stack as a middleware. If the end of the stack is reached

and no response has been generated, the `$handler` will be called.
