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.

Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "we need a main function to use it as libraries cannot be converted to executable files directly."

A block of code is set as follows:

    package main

    func main() {
      ten := 10
      if ten == 20 {
        println("This shouldn't be printed as 10 isn't equal to 20")
      } else {
        println("Ten is not equals to 20")
      }
    }

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

    if "a" == "b" || 10 == 10 || true == false {
      println("10 is equal to 10")
    } else if 11 == 11 && "go" == "go" {
        println("This won't because previous condition was satisfied")
      }
    }

Any command-line input or output is written as follows:

$ go run main.go

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "In order to download new modules, we will go to Files | Settings | Project Name | Project Interpreter."

Note

Warnings or important notes appear in a box like this.

Tip

Tips and tricks appear like this.
