Network Programming in Go: TCP/IP and WebSockets

In the modern web, real-time communication and low-latency networking are essential for building responsive applications. Understanding how to work directly with TCP/IP sockets and WebSockets gives you the power to build highly efficient backends that go beyond traditional HTTP. This text-based course guides you through the foundational concepts of network protocols and shows you how to implement them practically using the Go programming language. You will start with the absolute basics of network sockets, learning how data flows across the wire, before moving on to constructing robust, concurrent servers. What you will learn: Understand the core mechanics of TCP/IP and WebSocket protocols; Build a concurrent, multi-client TCP server from scratch using Go's net package; Implement real-time, bi-directional communication using WebSockets; Manage connection lifecycles and timeouts using Go's context package; Apply structured logging to monitor network connections and track errors; Practice handling concurrent connections safely with goroutines and channels. This course begins with essential networking terminology and protocol definitions, ensuring a solid foundation before you dive into hands-on implementation. You will progress from simple socket connections to building structured, production-ready network servers and clients. This course is designed for developers who are new to network programming but want to master real-time systems in Go, with no prior socket experience required.
