NestJS 11 now integrates Express 5 by default, streamlining error management. Express 5's notable enhancement is its ability to prevent application crashes caused by unhandled promise rejections, instead returning a 500 Internal Server Error. This allows developers to implement more sophisticated error handling strategies. Additionally, while NestJS retains its built-in exception layer that manages unhandled exceptions uniformly, it's beneficial to understand these Express-specific updates for better API implementation. The transition to Express 5 promises a more resilient and efficient experience for developers.
With NestJS 11, the framework introduces Express 5 by default, improving error handling without crashing the application for unhandled promise rejections.
