error-handling-patterns

To implement error handling for microservices, apply universal patterns like the Circuit Breaker to ensure API endpoints handle downstream service failures gracefully and maintain application reliability.

Handling exceptions and Result types effectively requires understanding language-specific error philosophies, utilizing custom exception hierarchies in Python, and applying universal patterns like Error Aggregation across Python, TypeScript, Rust, and Go.

You should use Result types instead of exceptions when you need explicit error propagation without control flow disruptions, particularly in languages like Rust and Go where returning errors directly is the standard convention.

Yes, you can use these error handling strategies with TypeScript and Go, as the guidance provides specific code examples for TypeScript/JavaScript and Go alongside Python and Rust to implement robust API design.

Graceful degradation matters for resilience because it allows your application to maintain partial functionality and preserve context during failures, rather than crashing completely, by following fail-fast and appropriate logging best practices.
