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 several patterns to organize code structures. Structural patterns are concerned about how to create objects, or how they do their business (we'll see this in the behavioral patterns).

Don't feel confused about mixing several patterns. You could end up mixing six or seven quite easily if you strictly follow the objectives of each one. Just keep in mind that over-engineering is as bad as no engineering at all. I remember prototyping a load balancer one evening, and after two hours of crazy over-engineered code, I had such a mess in my head that I preferred to start all over again.

In the next chapter, we'll see behavioral patterns. They are a bit more complex, and they often use Structural and Creational patterns for their objectives, but I'm sure that the reader will find them quite challenging and interesting.
