> 💿 `composer require dakujem/generic-middleware`

Contains a couple of classes:

- `GenericMiddleware`, an implementation of `Psr\Http\Server\MiddlewareInterface`
- `GenericHandler`, an implementation of `Psr\Http\Server\RequestHandlerInterface`

> Note that I'm using aliases `Request`, `Response` and `Handler` for their respective PSR interface names for brevity.
>
> Consider the following `use` statements in use:
>
> ```
> use Psr\Http\Message\ServerRequestInterface  as Request;
> use Psr\Http\Message\ResponseInterface       as Response;
> use Psr\Http\Server\RequestHandlerInterface  as Handler;
> ```

`GenericMiddleware`
-------------------

[](#genericmiddleware)

The [`GenericMiddleware`](src/GenericMiddleware.php) is a general purpose middleware that turns a callable into a PSR-15 implementation. It accepts any callable with signature `fn(Request,Handler):Response`.

It can be used for convenient inline middleware implementation:

```
$app->add(new GenericMiddleware(function(Request $request, Handler $next): Response {
    $request = $request->withAttribute('foo', 42);
    $response = $next->handle($request);
    return $response->withHeader('foo', 'bar');
}));
```

`GenericHandler`
----------------

[](#generichandler)

The [`GenericHandler`](src/GenericHandler.php) is a general purpose request handler, as per the PSR-15 specification. It turns a callable with signature `fn(Request):Response` into a PSR-15 implementation.

It can be used for convenient inline handler implementation where you don't want to bother with neither anonymous classes nor named classes:

```
$kernel = new GenericHandler(
    fn() => new Response(404, 'Not Found')
);
$dispatcher = new MiddlewareDispatcher($kernel);
```

Testing
-------

[](#testing)

Run unit tests using the following command:

`$` `composer test`
