middlewares/fast-route

Middleware to use FastRoute for handler discovery.

Requirements

• PHP >= 7.2
• A PSR-7 http library
• A PSR-15 middleware dispatcher

Installation

This package is installable and autoloadable via Composer as middlewares/fast-route.

composer require middlewares/fast-route

You may also want to install middlewares/request-handler.

Example

This example uses middlewares/request-handler to execute the route handler:

//Create the router dispatcher
$dispatcher = FastRoute\simpleDispatcher(function (FastRoute\RouteCollector $r) {
    $r->addRoute('GET', '/hello/{name}', function ($request) {
        //The route parameters are stored as attributes
        $name = $request->getAttribute('name');

        //You can echo the output (it will be captured and written into the body)
        echo sprintf('Hello %s', $name);

        //Or return a string
        return sprintf('Hello %s', $name);

        //Or return a response
        return new Response();
    });
});

$dispatcher = new Dispatcher([
    new Middlewares\FastRoute($dispatcher),
    new Middlewares\RequestHandler()
]);

$response = $dispatcher->dispatch(new ServerRequest('/hello/world'));

FastRoute allows anything to be defined as the router handler (a closure, callback, action object, controller class, etc). The middleware will store this handler in a request attribute.

Usage

Create the middleware with a FastRoute\Dispatcher instance:

$route = new Middlewares\FastRoute($dispatcher);

Optionally, you can provide a Psr\Http\Message\ResponseFactoryInterface as the second argument, that will be used to create the error responses (404 or 405). If it's not defined, Middleware\Utils\Factory will be used to detect it automatically.

$responseFactory = new MyOwnResponseFactory();

$route = new Middlewares\FastRoute($dispatcher, $responseFactory);

attribute

Changes the attribute name used to store the handler in the server request. The default name is request-handler.

$dispatcher = new Dispatcher([
    //Save the route handler in an attribute called "route"
    (new Middlewares\FastRoute($dispatcher))->attribute('route'),

    //Execute the route handler
    (new Middlewares\RequestHandler())->handlerAttribute('route')
]);
