Go in Action by William Kennedy, Brian Ketelsen, Erik St. Martin


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. Then, you'll get hands-on experience writing real-world applications including websites and network servers, as well as techniques to manipulate and convert data at speeds that will make your friends jealous.

Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

About the Technology

Application development can be tricky enough even when you aren't dealing with complex systems programming problems like web-scale concurrency and real-time performance. While it's possible to solve these common issues with additional tools and frameworks, Go handles them right out of the box, making for a more natural and productive coding experience. Developed at Google, Go powers nimble startups as well as big enterprises—companies that rely on high-performing services in their infrastructure.

About the Book

Go in Action is for any intermediate-level developer who has experience with other programming languages and wants a jump-start in learning Go or a more thorough understanding of the language and its internals. This book provides an intensive, comprehensive, and idiomatic view of Go. It focuses on the specification and implementation of the language, including topics like language syntax, Go's type system, concurrency, channels, and testing.

What's Inside

  • Language specification and implementation
  • Go's type system
  • Internals of Go's data structures
  • Testing and benchmarking

About the Reader

This book assumes you're a working developer proficient with another language like Java, Ruby, Python, C#, or C++.

‘Go in Action’ is a book by and for the Go community. It is the work of several authors that have started important initiatives and maintain an active role. Some examples include the establishment of Gophercon and goinggo.net. The book has two main goals: to give a comprehensive overview of the language for intermediate level programmers, and to introduce new gophers to several ‘established’ styles or design patterns for writing safe, idiomatic Go code. ‘Go in Action’ is not designed to provide many ready-to-use examples for web development, scientific calculations, or other ‘hands-on’ tasks. It is really about understanding how to control and share objects between processes and how to learn to write safe applications. Since it is aimed at intermediate level developers, the book skips a few elementary subjects including the built-in types, conversion and the math package. I was a little surprised by this since some Go basics are very essential for developers. In my opinion it is important to explain to new gophers that conversion is always explicit, that an int is not an int32 and that a float64 is a good way to express a decimal number since the math package uses double precision. This book gives new Go programmers a lot of great material to think about. When you are looking for a good way to think about sharing vs copying, and dataraces in concurrenct programs, this is where you can find helpful conceptual information and examples of how Go works internally. The authors show us how to think about sharing information, how exported objects are sometimes implemented using an unexported representation, and how dataraces work and how to detect them. Illustrations are exemplary and help new gophers tremendously. ‘Go in Action’ is best for new gophers with Java or C#/ C++ backgrounds, or at least backgrounds in statically typed languages, since developers with dynamic language backgrounds rarely (need to) look underneath the covers. I think it is a great read and I certainly recommend it for both beginning and more experienced Go programmers.
