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.

Preface

Chapter 4. Structural Patterns - Proxy, Facade, Decorator, and Flyweight Design Patterns

With this chapter, we will finish with the Structural patterns. We have left some of the most complex ones till the end so that you get more used to the mechanics of design patterns, and the features of Go language.

In this chapter, we will work at writing a cache to access a database, a library to gather weather data, a server with runtime middleware, and discuss a way to save memory by saving shareable states between the types values.
