SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Centralizes backend error handling to remove scattered try/catch blocks, ensuring consistent client-facing error contracts and safer logs.

Core Features & Use Cases

  • Domain/application error classes or enums to represent standard error states.
  • A global exception filter, middleware, or handler that translates exceptions into stable HTTP responses.
  • Safe client responses paired with actionable operator logs for monitoring and debugging.
  • Use cases include HTTP APIs, other client-facing transports, and background tasks that require uniform error semantics.

Quick Start

Implement a global error handler in your backend that intercepts thrown exceptions and returns a consistent error envelope to clients.

FAQPage Schema
How do I standardize API error responses across backend services?

Standardize API error responses by implementing a global exception handler that intercepts thrown exceptions and maps them to a consistent client-facing error envelope. This removes scattered try/catch blocks and ensures uniform HTTP status codes across services.

What is centralized error handling in backend APIs?

Centralized error handling is an architecture where a global filter or middleware intercepts exceptions and translates them into stable HTTP responses. It pairs safe client responses with actionable operator logs for monitoring and debugging.

How do I map domain exceptions to HTTP status codes?

Map domain exceptions to HTTP status codes by defining domain and application error classes, then using a global exception filter to translate these specific error states into appropriate transport-level statuses within a unified response structure.

How do I log backend API errors safely for operators?

Log backend API errors safely by routing exceptions through a centralized global handler that generates actionable operator logs for debugging. This ensures sensitive internal details are captured for monitoring while clients receive a safe, standardized response.

Can I use a global error handler for non-HTTP client-facing transports?

Yes, you can use a global error handler for non-HTTP transports. The centralized error handling architecture applies to any client-facing transport and background tasks requiring uniform error semantics, mapping exceptions to stable transport-level responses.

How do I remove scattered try/catch blocks in my backend code?

Remove scattered try/catch blocks by implementing a global exception filter or middleware to catch all thrown exceptions centrally. This handler translates standard error states into a consistent response envelope without requiring local error handling logic.
