go-error-mapper

What problem does it solve?

This Skill addresses the common issue in Go microservices where developers tend to return generic codes.Internal errors, obscuring the actual domain-specific error conditions and hindering proper error handling by clients.

Core Features & Use Cases

• Typed Domain Errors: Define custom, typed errors that represent specific business logic failures.
• gRPC Status Mapping: Automatically map these domain errors to appropriate gRPC status codes (e.g., NotFound, InvalidArgument).
• HTTP Status Mapping: Optionally map domain errors to corresponding HTTP status codes for RESTful APIs.
• Stack Trace Capture: Includes optional stack trace capture for enhanced debugging.
• Use Case: When a user is not found, instead of returning codes.Internal, this skill ensures the service returns codes.NotFound, allowing the client to handle this specific scenario gracefully.

Quick Start

Generate a Go error handling package that maps domain errors to gRPC and HTTP status codes.
