HTTP Middleware

FastForward Defer provides PSR-15 middleware for request-scoped deferred execution.

use FastForward\Defer\Middleware\DeferMiddleware;
$middleware = new DeferMiddleware();

// In your PSR-15 pipeline:
$response = $middleware->process($request, $handler);

The middleware:

• Creates a Defer instance per request
• Injects it into request attributes
• Ensures execution at the end of the request

use FastForward\Defer\DeferInterface;
$defer = $request->getAttribute(DeferInterface::class);
$defer(fn() => cleanup());
