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.

Builder design pattern - reusing an algorithm to create many implementations of an interface

Talking about Creational design patterns, it looks pretty semantic to have a Builder design pattern. The Builder pattern helps us construct complex objects without directly instantiating their struct, or writing the logic they require. Imagine an object that could have dozens of fields that are more complex structs themselves. Now imagine that you have many objects with these characteristics, and you could have more. We don't want to write the logic to create all these objects in the package that just needs to use the objects.

Description

Instance creation can be as simple as providing the opening and closing braces {} and leaving the instance with zero values, or as complex as an object that needs to make some API calls, check states, and create objects for its fields. You could also have an object that is composed of many objects, something that's really idiomatic in Go, as it doesn&apos...
