error-handling

To standardize error handling across TypeScript, Python, and Go, implement typed exception hierarchies and unified API error contracts. This ensures consistent error reporting, prevents silent failures, and maintains clear domain-specific error classes across your microservice architecture.

Implement retry mechanisms with exponential backoff for external API dependencies using structured resilience patterns. These patterns automatically handle unreliable service calls, like database connection timeouts, ensuring safe failure recovery through automated retries and circuit breakers.

Map internal server exceptions to user-facing API error responses by standardizing how errors are surfaced to clients. Use structured error boundaries to translate ambiguous internal failures into clear, actionable feedback while securely logging the internal details.

Create typed error hierarchies to replace ambiguous string error messages by defining a base AppError class. Extend this base class to build structured, domain-specific error classes that improve system reliability and observability across your application.

Yes, this approach supports building circuit breakers to handle unreliable external service calls. The resilience patterns include built-in logic for circuit breakers and retries with exponential backoff, ensuring safe failure recovery and protecting your system from cascading failures.
