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.

We have seen how to write a concurrent Singleton using mutexes and channels. While the channels example was more complex, it also shows the core power of Go's concurrency, as you can achieve complex levels of event-driven architectures by simply using channels.

Just keep in mind that, if you haven't written concurrent code in the past, it can take some time to start thinking concurrently in a comfortable way. But it's nothing that practice cannot solve.

We have seen the importance of designing concurrent apps to achieve parallelism in our programs. We have dealt with most of Go's primitives to write concurrent applications, and now we can write common concurrent design patterns.
