As developers, many of us are familiar with the concentric circles of Clean Architecture, where dependencies flow inward (as seen in the image below). This visual is essential for grasping how to structure our applications, but there's another crucial aspect that often gets overlooked: the flow of control.
🌀 The Dependency Diagram:
The circles illustrate the different layers - Entities, Use Cases, Interface Adapters, and Frameworks & Drivers. Dependencies always point inward, ensuring that the core of your application remains independent of external concerns like UI or databases.
➡️ The Flow of Control:
However, to truly harness the power of Clean Architecture, we need to understand the flow of control, which is depicted in the lower right corner of the clean architecture diagram . Here's a quick breakdown:
- Controller: Receives input from the UI and interacts with the Use Case Interactor.
- Use Case Interactor: Implements application-specific business rules and communicates with the Presenter.
- Presenter: Formats the data and presents it to the UI. Each of these steps is vital for maintaining a separation of concerns, ensuring that each layer has a distinct responsibility and does not interfere with others.
🔄 Why It Matters:
By adhering to this flow of control, we maintain a clear structure that is easier to test, maintain, and scale. It allows us to adapt and respond to changes in requirements or technology with minimal impact on the core logic of our applications.
So, next time you think about Clean Architecture, remember to look beyond the circles and consider how control flows through your application. This holistic view will help you build more robust, scalable, and maintainable software.
