Summary
In this chapter, we explored the Application layer of Clean Architecture, focusing on how it orchestrates domain objects and coordinates with external services to fulfill user needs. We learned how to implement use cases that maintain clean architectural boundaries while providing meaningful functionality.
Through our task management system example, we discovered how to create use case interactors that coordinate domain objects while respecting the Dependency Rule introduced in Chapter 1. We built upon the SOLID principles from Chapter 2 and the type-awareness patterns from Chapter 3 to create robust, maintainable implementations. Our use cases effectively orchestrate the domain objects and services we developed in Chapter 4, showing how Clean Architecture layers work together harmoniously.
We implemented several key patterns and concepts:
- Use case interactors that orchestrate domain operations
- Request and response models that create clear boundaries...
