cors-preflight

Lumen/Laravel package that creates a middleware for adding CORS headers to all incoming requests. It also adds Access-Control-Allow-Methods header to the OPTIONS requests with all the routes-registered methods. This is useful for preflight requests.

Example:

With this routes:

$router->get('/test', function () use ($router) {
    return $router->app->version();
});
$router->post('/test', function () use ($router) {
    return $router->app->version();
});

The response headers for OPTIONS request on /test route is:

Access-Control-Allow-Origin →*
Access-Control-Allow-Credentials →true
Access-Control-Max-Age →86400
Access-Control-Allow-Headers →Content-Type, Authorization, X-Requested-With
Access-Control-Allow-Methods →OPTIONS,GET,POST

Installation

Install this package using composer: composer require dusterio/lumen-passport

Enable middleware

You need to edit your bootstrap\app.php file and uncomment this line:

$app->withFacades();

and add this lines:

$app->middleware([
   Domoticalabs\CorsPreflight\CorsPreflightMiddleware::class
]);
