A robust application isn't one that never fails, but one that fails gracefully.
1The Global Handler
Instead of writing error logic in every route, use a single global middleware. It centralizes logging, formats the response, and ensures no sensitive stack traces are leaked to the client.
2Async Wrapper Pattern
Tired of try/catch in every route? You can use a wrapper function that automatically catches errors in async routes and forwards them to 'next'. It keeps your code clean and dry.
3Process Safety Nets
Sometimes an error happens outside of a request-response cycle. Listening for 'unhandledRejection' ensures your app doesn't crash unexpectedly due to a forgotten promise catch.
