Clean Architecture – Robert (Uncle Bob) Martin

Discover how to implement Clean Architecture principles in your software development projects, creating a modular, scalable, and maintainable system with a focus on simplicity, clarity, and testing.

Key takeaways

Clean Architecture is about separating the business logic from infrastructure concerns
The business logic must be contained within the business logic layer and not influenced by infrastructure
The goal is to achieve a high-level view of the system, focusing on the intent of the application
Use cases describe the intent of the application and should be used to drive the development of the business logic
The application should be designed around the use cases, with the business logic layer being the core of the system
The view model is a raw data structure that is displayed on the screen, and the view is responsible for rendering this model
The controller and presenter are plug-ins to the business logic, and the interactor is responsible for controlling the flow of data
The system should be designed to be modular, with each module having its own distinct responsibilities
The architecture should be kept simple, with a focus on simplicity and clarity
The system should be developed using test-driven development (TDD) principles, with a focus on writing tests before writing code
The architecture should be designed to allow for scalability and maintainability, with a focus on minimizing coupling between components
The database should be treated as an I/O device, with the focus on the business logic and infrastructure being decoupled.
The application should be designed to be fast, with a focus on throughput and responsiveness.
The system should be designed to be measured, with a focus on measuring and profiling the system to identify performance bottlenecks.
The system should be designed to be flexible, with a focus on allowing for changes to the architecture and infrastructure without affecting the business logic.
The system should be designed to be testable, with a focus on writing tests that can be run quickly and reliably.
