Go Programming Cookbook - Second Edition

By: Aaron Torres

Overview of this book

Go (or Golang) is a statically typed programming language developed at Google. Known for its vast standard library, it also provides features such as garbage collection, type safety, dynamic-typing capabilities, and additional built-in types. This book will serve as a reference while implementing Go features to build your own applications. This Go cookbook helps you put into practice the advanced concepts and libraries that Golang offers. The recipes in the book follow best practices such as documentation, testing, and vendoring with Go modules, as well as performing clean abstractions using interfaces. You'll learn how code works and the common pitfalls to watch out for. The book covers basic type and error handling, and then moves on to explore applications, such as websites, command-line tools, and filesystems, that interact with users. You'll even get to grips with parallelism, distributed systems, and performance tuning. By the end of the book, you'll be able to use open source code and concepts in Go programming to build enterprise-class applications without any hassle.

Using NoSQL with MongoDB

You may initially think that Go is better suited to relational databases due to Go structures and because Go is a typed language. When working with something like the github.com/mongodb/mongo-go-driver package, Go can nearly arbitrarily store and retrieve structure objects. If you version your objects, your schema can adapt and it can provide a very flexible development environment.

Some libraries do a better job of hiding or elevating these abstractions. The mongo-go-driver package is an example of a library that does an excellent job of the former. The following recipe will create a connection in a similar way to Redis and MySQL, but will store and retrieve an object without even defining a concrete schema.

Getting ready

Configure your environment according to these steps:

  1. Download and install Go 1.11.1 or above on youroperatingsystem fromhttps://golang.org/doc/install.
  2. Install Consul from https:/...
