This package provides a routing RequestHandler for Amp's HTTP server based on the request URI and method based on FastRoute.


This package can be installed as a Composer dependency.

composer require amphp/http-server-router


Router implements RequestHandler. Any attached RequestHandler and Middleware instances will receive any ServerObserver events.

Routes can be defined using the addRoute($method, $uri, $requestHandler) method. Please read the FastRoute documentation on how to define placeholders.

Matched route arguments are available in the request attributes under the Amp\Http\Server\Router key as an associative array.


$router = new Router;

$router->addRoute('GET', '/', new CallableRequestHandler(function () {
    return new Response(HttpStatus::OK, ['content-type' => 'text/plain'], 'Hello, world!');

$router->addRoute('GET', '/{name}', new CallableRequestHandler(function (Request $request) {
    $args = $request->getAttribute(Router::class);
    return new Response(HttpStatus::OK, ['content-type' => 'text/plain'], "Hello, {$args['name']}!");


The Router will decode the URI path before matching. This will also decode any forward slashes (/), which might result in unexpected matching for URIs with encoded slashes. FastRoute placeholders match path segments by default, which are separated by slashes. That means a route like /token/{token} won't match if the token contains an encoded slash. You can work around this limitation by using a custom regular expression for the placeholder like /token/{token:.+}.
