error-handler

Standardize API error handling by implementing an AppError hierarchy and a global Express error handler, enforcing a consistent error taxonomy and centralized response formatting across all endpoints. This ensures errors remain structured and easy to diagnose.

Implement retry logic with exponential backoff using a dedicated retry utility that automatically re-attempts failed API requests. This strategy improves system resilience by gradually increasing wait times between retries, preventing cascade failures during transient network issues.

A circuit breaker pattern improves API resilience by monitoring service failures and tripping to stop requests when error thresholds are reached. This prevents cascading system failures, allowing downstream services time to recover without being overwhelmed by repeated calls.

Create a consistent error code registry by defining a standardized error taxonomy and mapping each classification to structured output documentation. This centralizes error definitions for teams, ensuring uniform response formats and easier diagnosis across all endpoints.

Yes, you can implement a global Express error handler to achieve centralized error formatting for your APIs. This establishes a comprehensive error-handling framework that catches application errors uniformly and outputs standardized responses across all backend services.
