gRPC Microservices

Overview

gRPC is a high-performance RPC framework using Protocol Buffers for efficient, type-safe service communication. This skill should be invoked when building microservices requiring high performance, type-safe communication, or real-time streaming between services.

Core Principles

• Contract-First: Define services in .proto files
• Code Generation: Generate strongly-typed clients and servers
• Streaming: Support server, client, and bidirectional streaming
• Performance: Binary serialization is more efficient than JSON

Preparation Checklist

• Install protobuf compiler (protoc)
• Choose gRPC library for your language
• Design .proto service definitions
• Plan message structures
