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.

Bridge design pattern

The Bridge pattern is a design with a slightly cryptic definition from the original Gang of Four book. It decouples an abstraction from its implementation so that the two can vary independently. This cryptic explanation just means that you could even decouple the most basic form of functionality: decouple an object from what it does.


The Bridge pattern tries to decouple things as usual with design patterns. It decouples abstraction (an object) from its implementation (the thing that the object does). This way, we can change what an object does as much as we want. It also allows us to change the abstracted object while reusing the same implementation.


The objective of the Bridge pattern is to bring flexibility to a struct that change often. Knowing the inputs and outputs of a method, it allows us to change code without knowing too much about it and leaving the freedom for both sides to be modified more easily.
