Go by Example: Programmer's guide to idiomatic and testable code (Final Release)

Go beyond Go syntax into the language’s unique perspective on program design.Through engaging hands-on examples, Go by Example will teach you to think differently about programming in Go. You’ll get to grips with the “Go mindset”, writing code that’s simple, straightforward, and easy to understand for your fellow Go developers. You’ll discover how Go’s tooling helps you write code that’s robust and testable, and see just how productive you can be with Go's rich set of built-in packages.

In Go by Example you will learn how to
Understand what makes Go different and adopt its philosophy for simple, pragmatic, and straightforward code
Write idiomatic code that’s robust, efficient, maintainable, and inherently testable by design
Identify common Go mistakes and apply proven patterns for higher quality code
Structure and organize effective Go packages and APIs
Build performant concurrent programs with Go’s unique concurrency

Go by Example explores what makes Go so dramatically different from other languages. Through hands-on and realistic project examples—like command-line tools, web services, and scalable concurrent programs—it helps experienced developers unlearn habits and quickly become productive in crafting truly Go-like, high-quality code.

About the Technology
You can’t appreciate the simplicity, explicitness, and pragmatism of Go until you see it with your own eyes! Even a quick glance at an elegant interface or a bit of clean error handling code reveals why Go was the language of choice for Kubernetes, Docker, and Terraform.

About the Book
Go by Example unpacks real Go programs to highlight the language features and idiomatic coding practices used by the pros. In it, you’ll dissect and explore examples of command-line tools, concurrent programs, web services, and more as you learn to write Go code that’s simple, efficient, and testable.
