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.

This chapter has dealt with three extremely powerful patterns that require a lot of practice before using them in production code. It's a very good idea to make some exercises with them by simulating typical production problems:

  • Create a simple REST server that reuses most of the error-checking and connection functionality to provide an easy-to-use interface to practice the Template pattern

  • Make a small library that can write to different databases but only in the case that all writes were OK, or delete the newly created writes to practice Memento for example

  • Write your own language, to make simple things such as answering simple questions like bots usually do so you can practice a bit of the Interpreter pattern

The idea is to practice coding and reread any section until you get comfortable with each pattern.
