Routes

./config/routes.php is the file where you can register routes. The Slim documentation contains examples on how to create and configure routes: https://www.slimframework.com/docs/v4/objects/routing.html.

Also check Request handlers for more detailed information.

config/routes.php

return function (App $app) {
    // Set default route strategy.
    $routeCollector = $app->getRouteCollector();
    $routeCollector->setDefaultInvocationStrategy(new RequestResponseArgs());

    // The routes registered in your app.
    $app
        ->get('/your-route-slug', YourRequestHandler::class.':handle')
        ->setName('index');
};
