12 Excellent Free Books to Learn Go

Go is a compiled, statically typed programming language that makes it easy to build simple, reliable, and efficient software. It’s a general purpose programming language with modern features, clean syntax and a robust well-documented common library, making it a good candidate to learn as your first programming language. While it borrows ideas from other languages such as Algol and C, it has a very different character. It’s sometimes described as a simple language.

Go is an open source project developed by a team at Google and many contributors from the open source community. Go’s first release was in 2009, and it’s distributed under a BSD-style license.

This article selects the best open source books that will give readers a firm foundation in developing Go applications. There are also some books included that aren’t published under an open source license.


1. Go Bootcamp by Matt Aimonetti

Go BootcampGo Bootcamp – Everything you need to know to get started with Go teachers the reader, among other things, the pros and cons of static typing, what makes the language unique, what Go is good at, and what are the challenging aspects of the language.

The book offers exercises to help cement the knowledge learned.

Chapters include:

  • The Basics – looks at variables and inferred typing, constants, printing constants and variables, packages and imports, code location, exported names, and more.
  • Types – includes structs, initializing, composition vs inheritance and more.
  • Collection Types – arrays including multi-dimensional arrays, slices, range, and maps are explored.
  • Control flow – if statement, for loop, and switch case statement are covered.
  • Methods – types and methods allow for an object-oriented style of programming.
  • Interfaces – an interface type is defined by a set of methods. A value of interface type can hold any value that implements those methods.
  • Concurrency – explores one of the most interesting aspects of the Go language.
  • Get Setup – focuses on OS X.
  • Get Your Feet Wet.
  • Tips and Tricks – shares some tricks experienced developers discovered over time.

2. An Introduction to Programming in Go by Caleb Doxsey

An Introduction to Programming in GoAs the title suggests, this is a short, concise introduction to computer programming using the language Go.

Chapters cover:

  • Getting Started – covers files and folders, the terminal, text editors, and Go tools.
  • Your First Program – the obligatory “Hello World”.
  • Types – built-in data types: Numbers, Strings, and Booleans.
  • Variables – covers how to name a variable, scope, constants, defining multiple variables, and closing with an example program.
  • Control Structures – start to write useful programs by learning about control structures: for, if, and switch.
  • Arrays, Slices and Maps – looks at three more built-in types: arrays, slices and maps.
  • Functions – an independent section of code that maps zero or more input parameters to zero or more output parameters.
  • Pointers – examines the * and & operators, and new.
  • Structs and Interfaces – a struct is a type which contains named fields. For interfaces, the chapter explains the “method set”.
  • Concurrency – Go has rich support for concurrency using goroutines and channels.
  • Packages – another mechanism for code reuse.
  • Testing – Go includes a special program that makes writing tests easier.
  • The Core Packages – takes a look at some of the most commonly used packages included with Go.

4. Build Web Application with Golang by Astaxie

Build Web Application GolangThis book describes how to develop web application in Go, introducing a lot of basic knowledge, development tools and techniques. The book uses this knowledge to implement a simple web framework.

Chapters include:

  • Go basic knowledge.
  • Web foundation – talks about some concepts of the web and how to run web applications in Go.
  • HTTP Form – how to handle form data in Go, and how to validate form data.
  • Database – examines the database driver interface design in Go, before moving on to introducing SQM database drivers Go, and then presenting the ORM.
  • Data Storage and session – highlights the differences between cookies and sessions, session hijacking, and how to prevent it.
  • Text files – XML, JSON, regular expressions, the MVC pattern to develop applications in Go, ending with an introduction to file and folder operations.
  • Web services – Sockets, WebSocket, REST, and RPC are covered.
  • Security and encryption – CSRF attacks, filter inputs, XSS attacks, SQL injection, password storage, and encrypting and decrypting data.
  • Internationalization and localization – time zone, localized resources, and international sites.
  • Error handling, debugging and testing – describes how to handle errors in the Go language and how to design your own handling package and functions, how to use GDB to debug programs under dynamic operating conditions. The chapter moves on to explaining unit testing and in-depth discussions and examples on how to write unit tests.
  • Deployment and maintenance – logs, errors and crashes, deployment, and backup and recovery.
  • Build a web framework – introduces the MVC architecture, a routing and logging system and simple server configuration.
  • Develop web framework.
