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.

Reactive Programming and Data Streams

In this chapter, we will discuss reactive programming design patterns in Go. Reactive programming is a programming concept that focuses on data streams and the propagation of change. Technologies such as Kafka allow you to quickly produce or consume a stream of data. As a result, these technologies are a natural fit for one another. In the Connecting Kafka to Goflow recipe, we'll explore combining a kafka message queue with goflow to show a practical example of using these technologies. This chapter will also explore various ways to connect with Kafka and use it to process messages. Lastly, this chapter will demonstrate how to create a basic graphql server in Go.

In this chapter, we will cover the following recipes:

  • Using Goflow for data flow programming
  • Using Kafka with Sarama
  • Using async producers with Kafka
  • Connecting Kafka to...
