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.

Exploring Factories, Repositories, and Services

Factories, repositories, and services are the last major building blocks of domain-driven design (DDD) that we will learn about before bringing everything together in Part 2 of this book, where we will build some services from scratch.

None of the factories, repositories or services are unique to DDD and are often used in projects not using the DDD approach. This makes them especially important and useful to learn about, as you will see them everywhere.

In this chapter, we will cover the following topics:

  • The factory pattern – we will discuss what it is and when it is useful
  • The repository pattern – we will walk through some examples to help you understand how they differ from database tables
  • Services – we will look at domain services, application services, and infrastructure services and the difference between them all

By the end of this chapter, you will be able to understand factories...
