Go Design Patterns

By: Mario Castro Contreras

Overview of this book

Go is a multi-paradigm programming language that has built-in facilities to create concurrent applications. Design patterns allow developers to efficiently address common problems faced during developing applications. Go Design Patterns will provide readers with a reference point to software design patterns and CSP concurrency design patterns to help them build applications in a more idiomatic, robust, and convenient way in Go. The book starts with a brief introduction to Go programming essentials and quickly moves on to explain the idea behind the creation of design patterns and how they appeared in the 90’s as a common "language" between developers to solve common tasks in object-oriented programming languages. You will then learn how to apply the 23 Gang of Four (GoF) design patterns in Go and also learn about CSP concurrency patterns, the "killer feature" in Go that has helped Google develop software to maintain thousands of servers. With all of this the book will enable you to understand and apply design patterns in an idiomatic way that will produce concise, readable, and maintainable software.

A little bit of history and theory

When we talk about Go's concurrency, it's impossible not to talk about history. In the last decades, we saw an improvement in the speed of CPUs until we reached the hardware limits imposed by current hardware materials, design, and architectures. When we reached this point, we started to play with the first multicore computers, the first double CPU motherboards, and then single CPUs with more than one core in their heart.

Unfortunately, the languages we are using are still the ones created when we had single core CPUs, such as Java or C++. While being terrific systems languages, they lack a proper concurrency support by design. You can develop concurrent apps in both of the languages used in your project by using third party tools or by developing your own (not a very easy task).

Go's concurrency was designed with these caveats in mind. The creators wanted garbage collected and procedural language that is familiar for newcomers, but which, at the same time...
