Building High-Performance APIs with gRPC and Go

Modern backend systems require fast, efficient, and reliable communication between services. Traditional REST APIs can introduce latency and overhead, which is why developers turn to gRPC and Go to build high-performance microservices. This text-based course guides you through the core concepts of gRPC and Go, showing you how to design, implement, and maintain lightweight communication channels for modern applications. What you will learn: Understand the core architecture of gRPC and how it differs from traditional REST APIs; Define structured data and service interfaces using Protocol Buffers (Protobuf) syntax; Implement robust gRPC servers and clients in Go using modern programming patterns; Apply context propagation to handle timeouts, deadlines, and cancellations gracefully; Write structured unit tests for your gRPC services to ensure reliability. You will start with foundational concepts, learning the terminology and structure of Interface Definition Languages (IDLs). From there, you will progress to writing clean Go code to run servers, connect clients, and manage network communication effectively. This course is designed for backend developers and Go beginners who want to expand their API development toolkit. No prior experience with gRPC is required, though a basic understanding of Go syntax is helpful. Start reading today to build faster, more efficient Go applications.
