Stop using try-catch in every controller. Instead, use global exception handling and middleware to manage errors centrally. This keeps controllers clean, improves maintainability, ensures consistent responses, and follows best practices in modern web application architecture.
Problem: Try-Catch in Every Controller
- Every controller duplicates the same try-catch block.
- Controllers mix business logic, error handling, and logging.
- Any change to error handling requires editing multiple controllers.
- Different developers return different error formats or status codes.
- You can’t isolate logic easily due to embedded exception handling.
- Adding new exception types means rewriting every controller again.
Solution : Middleware Code(ExceptionMiddleware)
- This middleware catches all unhandled exceptions in the request pipeline, so you don’t need to use try-catch in every controller.
- It logs the error using ILogger, making debugging and monitoring easier.
Register the Middleware
- Registers the custom middleware in the request pipeline so it runs on every request.
- Ensures global exception handling by catching unhandled errors before they reach the response.
Benifits
- You don’t need to write try-catch in every controller.
- All errors are handled in one place, making the code clean and simple.
- It gives the same type of error response every time.
- Easy to find and fix problems because all exceptions are logged.
- Makes the application more secure by not showing detailed error messages to users.
- Improves maintenance since error handling logic is centralized.
Conclusion
In conclusion, avoid placing try-catch blocks in every controller. Use centralized exception handling to keep code clean, consistent, and maintainable while ensuring better error management and improved application architecture.
