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.

“When a lead uses our app for the first time, they must pick one of three subscription plans. These are basic, premium, and exclusive. Depending on which they pick determines which features they get access to within the app. This may change over time. Once a subscription plan has been created, we consider that the lead has converted to a customer, and we call them a customer until they churn. At this point, we call them a lead again. After 6 months, we call them a lost lead and we might target them with a re-engagement campaign, which could include a discount code. Once a plan is created, we set up a recurring payment to capture funds from the customer...
