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.

Adapter design pattern

One of the most commonly used structural patterns is the Adapter pattern. Like in real life, where you have plug adapters and bolt adapters, in Go, an adapter will allow us to use something that wasn't built for a specific task at the beginning.

Description

The Adapter pattern is very useful when, for example, an interface gets outdated and it's not possible to replace it easily or fast. Instead, you create a new interface to deal with the current needs of your application, which, under the hood, uses implementations of the old interface.

Adapter also helps us to maintain the open/closed principle in our apps, making them more predictable too. They also allow us to write code which uses some base that we can't modify.

Note

The open/closed principle was first stated by Bertrand Meyer in his book Object-Oriented Software Construction. He stated that code should be open to new functionality, but closed to modifications. What does it mean? Well, it implies...
