The Little Go Book is a free introduction to Google's Go programming language. It's aimed at developers who might not be quite comfortable with the idea of pointers and static typing. It's longer than the other Little books, but hopefully still captures that little feeling.
This book is a short, concise introduction to computer programming using the language Go. Designed by Google, Go is a general purpose programming language with modern features, clean syntax and a robust well-documented common library, making it an ideal language to learn as your first programming language.
This companion book contains material initially written specifically for this event as well as content from Google & the Go team under Creative Commons Attribution 3.0 License and code licensed under a BSD license.
This book helps Javascripters become Gophers. Outlining the differences between these languages makes it easier to switch back and forth, and can help mitigate potential issues when doing so.
Learn Go guided by tests. Write a test, learn a new Go language feature to make it pass, refactor and repeat. You'll get a grounding in test-driven development and importantly understand the principles behind it.
Go 101 is a book focusing on Go syntax/semantics and all kinds of runtime related things (Go 1.17-pre ready) and tries to help gophers gain a deep and thorough understanding of Go. This book also collects many details of Go and in Go programming. It is expected that this book is helpful for both beginner and experienced Go programmers.
Go in Action introduces the Go language, guiding you from inquisitive developer to Go guru. The book begins by introducing the unique features and concepts of Go. (We assume you're up to speed with another programming language already, so don't expect to spend a lot of time rehearsing stuff you already know.) Then, you'll get hands-on experience writing real-world applications including web sites and network servers, as well as techniques to manipulate and convert data at speeds that will make your friends jealous. In the final chapters, you'll go in-depth with the language and see the tricks and secrets that the Go masters are using to make their applications perform. For example, you'll learn to use Go's powerful reflection libraries and work with real-world examples of integration with C code.
This book shows you how to build powerful systems and drops you into real-world situations. Scale, performance, and high availability lie at the heart of our projects, and the lessons learned throughout this book will arm you with everything you need to build world-class solutions.

Presented in an engaging, hands-on way, this book focuses on the features of Go that are used by professionals in their everyday work.
Go is rapidly becoming the preferred language for building web services. While there are plenty of tutorials available that teach Go's syntax to developers with experience in other programming languages, tutorials aren't enough. They don't teach Go's idioms, so developers end up recreating patterns that don't make sense in a Go context. This practical guide provides the essential background you need to write clear and idiomatic Go.
No matter your level of experience, you'll learn how to think like a Go developer. Author Jon Bodner introduces the design patterns experienced Go developers have adopted and explores the rationale for using them. You'll also get a preview of Go's upcoming generics support and how it fits into the language.
- Learn how to write idiomatic code in Go and design a Go project
- Understand the reasons for the design decisions in Go
- Set up a Go development environment for a solo developer or team
- Learn how and when to use reflection, unsafe, and cgo
- Discover how Go's features allow the language to run efficiently
- Know which Go features you should use sparingly or not at all
Starting from the basics and building up to the most advanced and sophisticated features. You will learn how Go builds on a simple and consistent type system to create a comprehensive and productive development experience that produces fast and robust applications that run across platforms.
- Gain a solid understanding of the Go language and tools
- Gain in-depth knowledge of the Go standard library

However, it might end up with mess if you are not aware about best practices of this transition, since Microservice Architecture comes with its challenges. In this book, we start covering production grade best practices of Microservices Architecture and explain when to use it. Then we talk about microservice communication patterns where gRPC comes to the stage. You will see complete examples written in Go with Hexagonal Architecture applied to project structure. You will not only learn how to implement microservices, you will see how to write tests, maintain quality with proper CI, deploy to Kubernetes environment and finally set up an observable system to have better monitoring for your application.
Gin is a high-performance HTTP web framework used to build web applications and microservices in Go. This book is designed to teach you the ins and outs of the Gin framework with the help of practical examples.
