error-handling

Error handling in TypeScript requires classifying failures into domain, infrastructure, and system levels. This structured taxonomy ensures you wrap validation errors for user-facing messages while propagating infrastructure and system errors for distributed tracing and alerting.

The best way to propagate errors in Go is using a decision tree to determine when to bubble, wrap, or translate them. Wrapping errors preserves the original context and distributed tracing data while allowing you to add actionable, secure user-facing messages at the API boundary.

An error taxonomy improves resilience by categorizing errors into distinct levels, enabling consistent logging, alerting, and propagation strategies. This classification prevents infrastructure failures from being masked as domain bugs, ensuring developers can apply the correct recovery or translation pattern.

You should translate errors when crossing service or API boundaries to provide actionable, secure user-facing guidelines, and bubble errors when internal context must be preserved. A propagation decision tree helps determine the exact boundary where internal system errors become external infrastructure errors.

Yes, the framework provides language-specific error creation and propagation patterns for Go, TypeScript, and Python. It enforces best practices for consistent error management, secure user-facing messaging, and distributed tracing context across these specific programming environments.
