Enabling the Attribute Router

Attribute router extends slims default RouteCollector, all you need to do is instantiate attribute router and pass it on to AppFactory. First parameter is array of namespace parts of app. It will be used for filtering classes in which search of parameters will go on.

<?php
use OpsWay\Slim\AttributeRouter\Router;
use Slim\Factory\AppFactory;
$route = new Router([
    ['NameSpace'], // array of namespaces parts of app 
	AppFactory::determineResponseFactory(),
	new CallableResolver($container) // optional DI container
);
AppFactory::setRouteCollector($attributeRouteCollector);
$app = AppFactory::create();
$app->run();

Attribute signature

#[Route({methods}, {path}[[, {group}][, {name}][, {isDeprecated}]])]

• The "secondClass" and all other parameters is optional.
• All arguments of constructor are converted to an array of middleware classes. It should be at least one middleware class

Specifying attributes examples

Example specifying route with name and group parameters at class level

<?php
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;

#[Route([Route::METHOD_GET], '/api/hello-world', '/hello-world-group', 'api.hello-world.route-name')]
class HelloWorld
{
    public function __invoke(Request $request, Response $response): Response
    {
        // some php code
        return $response;
    }
}

Example specifying route without additional parameters at method level

<?php
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;

class HelloWorld
{
    #[Route([Route::METHOD_GET], '/api/hello-world')]
    public function __invoke(Request $request, Response $response): Response
    {
        // some php code
        return $response;
    }
}

Example specifying group with middlewares at class level

<?php
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;

#[Group('/api', [FirstMidleware::class, SecondMidleware::class])]
class HelloWorld
{
    public function __invoke(Request $request, Response $response): Response
    {
        // some php code
        return $response;
    }
}
