Consider a production Laravel application that needs to use Custom middleware. 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 custom middleware 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: Applications can create custom middleware for business or security rules that belong at the request boundary. A useful implementation pattern is: public function handle($request, Closure $next) { if (! $request->user()) { return redirect('/login'); } return $next($request); }
