Building TCP and WebSocket Servers in Go

Modern web applications require fast, bi-directional, and real-time communication. Understanding how to build low-level TCP and high-level WebSocket servers in Go gives you the power to create highly scalable network services. This text-only course guides you through the core concepts of network programming. You will progress from understanding basic sockets to writing fully functional, concurrent TCP and WebSocket servers in Go, utilizing modern Go standards such as structured logging and context-driven cancellation. What you'll learn: - Understand the fundamental differences between TCP/IP and WebSocket protocols - Establish robust TCP connections and handle data streams using Go's net package - Build concurrent network servers using goroutines and the context package for safe termination - Implement WebSocket handshakes and manage persistent bi-directional connections - Apply structured logging and modern error handling practices to network applications - Practice building a practical server that processes real-time client requests You will start with the foundational terminology of networking, ports, and protocols before diving into the Go standard library's network packages. Through step-by-step written explanations and structured code exercises, you will construct a working TCP server and transition into a real-time WebSocket server. This course is designed for beginner Go developers who want to expand their skills into network programming. No prior networking or systems programming experience is required.
