Network Programming in Go: Building TCP/IP and WebSocket Applications

Network communication is the backbone of modern software, yet transitioning from basic HTTP APIs to low-level protocols can feel daunting. This text-based course guides you through the core concepts of network programming using Go's powerful standard library and modern concurrency primitives. You will transition from a networking novice to confidently designing, writing, and debugging your own TCP/IP and WebSocket servers and clients, establishing a solid foundation in real-time data transmission. What you'll learn: 1. Understand foundational networking terminology, including IP routing, ports, sockets, and the differences between TCP and UDP. 2. Build robust TCP servers and clients in Go using the standard net package. 3. Implement real-time, bidirectional communication using the WebSocket protocol. 4. Manage concurrent connections safely using Go's goroutines, channels, and the context package for timeouts and cancellations. 5. Handle network errors gracefully and implement proper resource cleanup practices. 6. Practice writing clean, modern Go code with structured error wrapping and standard project layouts. The course starts with essential theoretical foundations of networking protocols before guiding you through building functional TCP applications and transitioning to real-time WebSockets. You will read detailed explanations, analyze structured code snippets, and complete written exercises to reinforce your learning. This course is designed for beginner to intermediate Go developers who want to expand their backend skills into network programming; no prior networking experience is required.
