Consider a production Laravel application that needs to use Event design. How should the developer approach the requirement, and what should be checked before releasing it? Assume the system receives real users, real data and concurrent requests. The correct approach is to identify where event design belongs, define its inputs and outputs, protect the boundary with validation and authorization where applicable, consider database and performance implications, and add automated tests for the expected behavior. Concept-specific reasoning: Events should communicate stable business facts rather than leaking every low-level implementation detail. A useful implementation pattern is: event(new OrderPlaced($order)); // Listener public function handle(OrderPlaced $event): void { Mail::to($event->order->customer_email)->queue(new OrderReceipt($event->order)); }
