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.

What this book covers

Chapter 1, A Brief History of Domain-Driven Design helps you learn about the origins of DDD – no Golang in this chapter!

Chapter 2, Understanding Domains, Ubiquitous Language, and Bounded Contexts teaches you these core domain-driven topics.

Chapter 3, Entities, Value Objects, and Aggregates will help you learn a few more DDD topics.

Chapter 4, Exploring Factories, Repositories, and Services is the final chapter of Part 1, and sees us learn three more DDD patterns that will help cement our understanding.

Chapter 5, Applying DDD to a Monolithic Application teaches how we can apply domain-driven design to both an existing monolithic application, but also to a new one we will build together.

Chapter 6, Building a Microservice using DDD shows how to build a microservice using DDD that is resilient to failure.

Chapter 7, DDD for Distributed Systems takes you through how DDD can be applied to entire distributed systems as well as covering topics such as message queues at a foundational level.

Chapter 8, TDD, BDD and BDD is a bonus chapter that covers how test-driven development, behaviour-driven development, and domain-driven development can be complimentary patterns.
