error-handling

You standardize error responses across NestJS, Django, and React by applying global exception filters, custom handlers, and React Error Boundaries that enforce a structured format with fields like statusCode, error, message, details, and correlationId.

The best way to trace errors end-to-end in a full-stack application is by using correlation-id middleware that propagates a unique identifier across backend and frontend services, enabling end-to-end traceability and centralized logging with context.

A circuit breaker pattern protects downstream services by monitoring failures and stopping traffic to a failing service, while retry logic with exponential backoff and jitter handles transient errors to ensure resilient inter-service calls.

Yes, this error-handling solution works with Django REST Framework and NestJS by providing a Django REST Framework custom exception handler and a global exception filter for NestJS to normalize errors and unify error formats.

You prevent UI crashes in React when a component throws an error by implementing a React Error Boundary to catch UI errors, normalize the error format, and provide structured responses to prevent full application crashes.
