require __DIR__ . '/vendor/autoload.php';

use SubjectivePHP\Slim\Middleware;

// This Slim setting is required for the middleware to work
$app = new Slim\App([
    "settings"  => [
        "determineRouteBeforeAppMiddleware" => true,
    ]
]);

// create the middleware
$optionsMiddleware = new Middleware\OptionsMiddleware('*', ['Authorization', 'Content-Type']);

$app->map(['GET', 'POST'], 'foos', function ($request, $response, $args) {
    return $response;
};

$app->add($optionsMiddleware);

$app->run();
