Domain-Driven Design with Golang

Overview of this book

Domain-driven design (DDD) is one of the most sought-after skills in the industry. This book provides you with step-by-step explanations of essential concepts and practical examples that will see you introducing DDD in your Go projects in no time. Domain-Driven Design with Golang starts by helping you gain a basic understanding of DDD, and then covers all the important patterns, such as bounded context, ubiquitous language, and aggregates. The latter half of the book deals with the real-world implementation of DDD patterns and teaches you how to build two systems while applying DDD principles, which will be a valuable addition to your portfolio. Finally, you’ll find out how to build a microservice, along with learning how DDD-based microservices can be part of a greater distributed system. Although the focus of this book is Golang, by the end of this book you’ll be able to confidently use DDD patterns outside of Go and apply them to other languages and even distributed systems.

A Brief History of Domain-Driven Design

Welcome to this book on domain-driven design (DDD) using Golang. If you have never heard of DDD before, I hope that by the end of this book, you will have a good understanding of what it is, where it came from, how it can be applied, and how to implement some of the patterns popular among DDD proponents using Golang.

You might be surprised to discover that a large part of the first half of this book will be defining terms and discussing patterns on how to work with others to build systems that represent the real world. At its core, this is what DDD is about. Don’t worry though; there will be plenty of Golang examples, and in Part 2, we will dive deeper into building out DDD-based systems.

In this chapter, we will explore how DDD emerged and gained popularity. I find this context particularly valuable as we delve deeper into the topic as it helps you understand why to use it, not just how.

In this chapter, we will cover the following topics:

  • The world before DDD
  • Eric Evans and DDD
  • Three pillars of DDD
  • Adoption of DDD
  • When should you use DDD?
