error-handling-patterns

To prevent cascading failures in a microservice, implement the Circuit Breaker pattern and graceful degradation to manage downstream network failures safely. This approach isolates faults and improves overall system resilience.

Implement custom exception hierarchies by defining domain-specific error classes that inherit from base exceptions, allowing precise error trapping and propagation. This structured approach improves debugging experiences and API reliability.

Exceptions offer traditional control flow in TypeScript, while Result types enforce explicit error checking in Rust. Choosing between them depends on language idioms and whether you prefer explicit error propagation over implicit exceptions.

Yes, the error handling guidance provides language-specific patterns and examples for Python, Go, JavaScript, and TypeScript. It covers universal patterns like Option types and error codes across these multiple programming languages.

Use graceful degradation instead of standard error codes when a downstream service fails but partial functionality can still be provided. This pattern ensures the application remains partially operational, improving user experience during localized failures.
