Description
Clean Architecture provides a structured approach to software development that promotes separation of concerns and increases the maintainability, testability, and flexibility of applications. By applying principles such as Dependency Inversion and Separation of Concerns, an architecture is created that can easily adapt to changes.
✔Benefits
- Increased Maintainability
- Better Testability
- Flexibility in Changes
✖Limitations
- Requires experienced developers
- Can appear complex initially
- Potential over-engineering
Trade-offs
Metrics
- Code Quality
Assessment of the maintainability and readability of the code.
- Test Coverage
Percentage of the code covered by tests.
- Development Time
Time required to implement new features.
Examples & implementations
E-Commerce Platform
An e-commerce platform that applies Clean Architecture to integrate various modules such as payment, shipping, and user management.
Financial Application
A financial application that achieves high maintainability and testability through separation of concerns.
Social Networking Platform
A social networking platform that uses Clean Architecture to facilitate the integration of new features.
Implementation steps
Train the team in Clean Architecture
Create an architecture plan
Iterative implementation of modules
⚠️ Technical debt & bottlenecks
Technical debt
- Insufficient tests due to time pressure.
- Lack of documentation of the architecture.
- Outdated dependencies in the software.
Known bottlenecks
Misuse examples
- Using Clean Architecture for small projects where it is not necessary.
- Ignoring the principles of Clean Architecture during implementation.
- Excessive complexity due to incorrect application of the architecture.
Typical traps
- Assuming that Clean Architecture is always the best solution.
- Believing that implementation is easy without experience.
- Underestimating the training needs for the team.
