Learning Go Programming

Overview of this book

The Go programming language has firmly established itself as a favorite for building complex and scalable system applications. Go offers a direct and practical approach to programming that let programmers write correct and predictable code using concurrency idioms and a full-featured standard library. This is a step-by-step, practical guide full of real world examples to help you get started with Go in no time at all. We start off by understanding the fundamentals of Go, followed by a detailed description of the Go data types, program structures and Maps. After this, you learn how to use Go concurrency idioms to avoid pitfalls and create programs that are exact in expected behavior. Next, you will be familiarized with the tools and libraries that are available in Go for writing and exercising tests, benchmarking, and code coverage. Finally, you will be able to utilize some of the most important features of GO such as, Network Programming and OS integration to build efficient applications. All the concepts are explained in a crisp and concise manner and by the end of this book; you would be able to create highly efficient programs that you can deploy over cloud.

Summary


This chapter condenses several important notions about creating networked services in Go. It starts with a walkthrough of Go's net package including the net.Conn type to create a connection between network nodes, the net.Dial function to connect to a remote service, and the net.Listen function to handle incoming connections from a client. The chapter continues to cover different implementations of clients and server programs and shows the implications of creating custom protocols directly over raw TCP versus using an existing protocol such as HTTP with JSON data format.

The next chapter takes a different direction. It explores the packages, types, functions, and tools that are available in Go to facilitate source code testing.
