Networking with Go, Made Easy

Free, open-source book (151 chapters, 6 parts) that teaches computer networking and network programming in Go end to end: how networks actually work, how to write real networking code in Go, and how to use that code to build production-grade APIs and do offensive/defensive security work. Covers TCP/IP, UDP, HTTP, WebSockets, DNS, goroutines, channels, context, gRPC, WebRTC, TLS, and production REST APIs with Gin, Fiber, PostgreSQL, Docker, and Clean Architecture. Every hands-on example is a complete, runnable Go program, not a fragment.
