SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Go gRPC services require a cohesive pattern to ensure correct error handling, health checks, and maintainable code. This skill consolidates best practices for building, reviewing, and debugging Go gRPC servers and clients, organizing protobufs, and setting up testing with bufconn.

Core Features & Use Cases

  • Guidelines for service definition, code generation, and clean separation of business logic via interceptors.
  • Guidance on TLS/mTLS, health checks, error mapping with status codes, and forward-compatible server embedding.
  • Practical patterns for testing with bufconn and streaming RPCs in production-grade systems.

Quick Start

Start by structuring your Go gRPC service with health checks, interceptors, and UnimplementedServer embedding, then progressively add TLS, testing, and robust error handling.

FAQPage Schema
How do I structure a production-ready Go gRPC service?

Configure Go gRPC services by adding health checks, wrapping calls with interceptors, embedding Unimplemented*Server for forward compatibility, and mapping errors to status codes. This structure separates business logic and ensures maintainable production-grade servers.

What is the best way to test gRPC services in Go?

The best way to test gRPC services in Go is using bufconn. This pattern allows you to test servers and clients, including streaming RPCs, without relying on actual network ports, ensuring reliable and isolated test execution for production-grade systems.

How does TLS and mTLS configuration work for Go gRPC?

TLS and mTLS configuration secures client-server communication by requiring certificate exchange. This skill provides guidance on setting up mutual TLS to ensure encrypted, authenticated connections within your production-grade gRPC infrastructure.

Why do I need to embed UnimplementedServer in my Go gRPC service?

You need to embed Unimplemented*Server in Go gRPC services to maintain forward compatibility. It ensures your service remains compilable and operational when new RPC methods are added to protobuf definitions but not yet implemented in the server.

How do I handle error mapping with status codes in gRPC?

Handle error mapping in gRPC by translating application-level errors into standard gRPC status codes. This skill enforces proper error handling patterns, allowing clients to programmatically react to specific failure types like invalid arguments or internal errors.

Can I use interceptors for clean separation of business logic in gRPC?

Yes, you can use interceptors in gRPC for clean separation of business logic. Interceptors allow you to wrap RPC calls to handle cross-cutting concerns like logging or authentication, keeping core service methods focused on business rules.
