middlewares/aura-router

Middleware to use Aura.Router and store the route handler in a request attribute.

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/aura-router.

composer require middlewares/aura-router

Example

In this example, we are using middleware/request-handler to execute the route handler:

//Create the router
$router = new Aura\Router\RouterContainer();

$map = $router->getMap();

$map->get('hello', '/hello/{name}', function ($request) {

    //The route parameters are stored as attributes
    $name = $request->getAttribute('name');

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

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

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

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

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

Aura.Router allows to define anything 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 Aura\Router\RouterContainer instance:

$routerContainer = new Aura\Router\RouterContainer();

$route = new Middlewares\AuraRouter($routerContainer);

Optionally, you can provide a Psr\Http\Message\ResponseFactoryInterface as the second argument, that will be used to create the error responses (404, 405 or 406). If it's not defined, Middleware\Utils\Factory will be used to detect it automatically.

$routerContainer = new Aura\Router\RouterContainer();
$responseFactory = new MyOwnResponseFactory();

$route = new Middlewares\AuraRouter($routerContainer, $responseFactory);

attribute

The name of the server request attribute used to save the handler. The default value is request-handler.

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

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