Wraps PSR-15 middleware using async and await from react/async utilizing fibers making them usable within react/http as middleware.

Install

To install via Composer, use the command below, it will automatically detect the latest version and bind it with ^.

composer require for/http-middleware-psr15-adapter

Usage

The following usage example uses middlewares/redirect adding one redirect, and using the callback to call several methods on the redirect middleware to change it's behavior:

$server = new Server(
    /** Other middleware */
    new PSR15Middleware(
        (new Redirect(['/old-url' => '/new-url']))->permanent(false)->query(false)->method(['GET', 'POST'])
    ),
    /** Other middleware */
);

Grouped Usage

When using more then one PSR-15 in a row the GroupedPSR15Middleware is more performing than using multiple PSR15Middleware. Consider the following example where we add middlewares/cache for expires headers:

$loop = Factory::create(); 
$server = new Server([
    /** Other middleware */
    (new GroupedPSR15Middleware($loop))->withMiddleware( 
        (new Redirect(['/old-url' => '/new-url']))->permanent(false)->query(false)->method(['GET', 'POST'])
    )->withMiddleware(
        new Expires()
    ),
    /** Other middleware */
]);
