Hands-On gRPC Services with Go

Modern microservices require fast, efficient, and strongly-typed communication. If you want to move beyond traditional REST APIs, gRPC offers a powerful framework for building high-performance services in Go. This text-based course guides you from the fundamental concepts of Remote Procedure Calls to implementing fully functional gRPC servers and clients in Go. You will start with the absolute basics of Protocol Buffers, learn how to define service contracts, and write clean, idiomatic Go code to handle network communication. What you'll learn: Understand the core differences between REST and gRPC architecture; Define robust service contracts using Protocol Buffers syntax; Implement gRPC servers and client applications in Go; Apply modern error-handling techniques using standard gRPC status codes; Configure streaming RPCs for real-time data exchange; Write basic unit tests to verify your gRPC service logic. The journey begins with core definitions and structural concepts before moving into code generation, server implementation, and client-side integration. You will read clear explanations and review step-by-step code snippets designed to build your practical skills. This course is designed for backend developers and Go beginners who want to expand their API development skills. No prior experience with gRPC is required, though a basic understanding of Go syntax is helpful. Start reading today and learn how to build efficient, scalable services with gRPC and Go.
