Application Services represent the Application layer of your Bounded Context. These high-level use cases should be relatively simple and skinny, as their purpose evolves around Domain coordination. Application Services are the entry point for Domain logic interaction. We've seen that Requests and Commands keep things organized; that DTOs and Data Transformers allow us to decouple data representation from Domain conceptualization; that building Application Services is pretty straightforward with Dependency Injection Containers; and that we have plenty of options for combining Application Services in complex layouts.

Overview of this book
Domain-Driven Design (DDD) has arrived in the PHP community, but for all the talk, there is very little real code. Without being in a training session and with no PHP real examples, learning DDD can be challenging. This book changes all that. It details how to implement tactical DDD patterns and gives full examples of topics such as integrating Bounded Contexts with REST, and DDD messaging strategies. In this book, the authors show you, with tons of details and examples, how to properly design Entities, Value Objects, Services, Domain Events, Aggregates, Factories, Repositories, Services, and Application Services with PHP. They show how to apply Hexagonal Architecture within your application whether you use an open source framework or your own.
