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 few approaches to develop concurrent structures that can be run in parallel. We have tried to show a few ways to solve the same problem, one without concurrency primitives and one with them. We have seen how different the publish/subscriber example written with a concurrent structure can be compared to the classic one.

We have also seen how to build a concurrent operation using a pipeline and we have parallelize it by using a worker pool, a very common Go pattern to maximize parallelism.

Both examples were simple enough to grasp, while digging as much as possible in to the nature of the Go language instead of in the problem itself.
