Lightweight gRPC Services with Twirp and Go

Modern backend development requires fast, reliable, and type-safe communication between services. While standard gRPC is powerful, Twirp offers a simpler, lightweight alternative that runs seamlessly over HTTP/1.1 and HTTP/2 using Protocol Buffers. This text-only course shows you how to leverage these tools to build highly performant APIs with minimal overhead. By reading through this practical guide, you will transition from understanding basic serialization concepts to writing clean, production-ready microservices with automated code generation. You will learn to design robust service contracts and implement them using modern Go standards. What you'll learn: - Understand the core concepts of Protocol Buffers and how they define service contracts. - Generate clean Go code for servers and clients automatically using Twirp. - Implement structured error handling and context-driven metadata propagation. - Design type-safe API endpoints that support both JSON and binary Protobuf serialization. - Apply modern Go project structures and dependency management for microservices. - Test your Twirp services using standard Go testing practices and mock clients. The course begins with foundational definitions of RPC, protocol buffers, and the Twirp framework. You will then progress through step-by-step written explanations and detailed code snippets, building a working backend service from the ground up. This course is designed for backend developers and Go beginners who want to build efficient APIs without the complexity of full gRPC setups. Familiarity with basic Go syntax is helpful, but no prior experience with gRPC or protocol buffers is required. Start reading today to simplify your microservice communication with Twirp and Go.
