Go Design Patterns

1.8 (6)
By: 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.

Facade design pattern


The next pattern we'll see in this chapter is the Facade pattern. When we discussed the Proxy pattern, you got to know that it was a way to wrap an type to hide some of its features of complexity from the user. Imagine that we group many proxies in a single point such as a file or a library. This could be a Facade pattern.

Description

A facade, in architectural terms, is the front wall that hides the rooms and corridors of a building. It protects its inhabitants from cold and rain, and provides them privacy. It orders and divides the dwellings.

The Facade design pattern does the same, but in our code. It shields the code from unwanted access, orders some calls, and hides the complexity scope from the user.

Objectives

You use Facade when you want to hide the complexity of some tasks, especially when most of them share utilities (such as authentication in an API). A library is a form of facade, where someone has to provide some methods for a developer to do certain things...
