Designing Clean Architecture inside Nest.js REST APIs
Implementing domain-driven design, decoupling database schemas from business logic, and structuring testable services.
Allowing framework code or database schemas to dictate domain logic leads to rigid apps. Clean architecture separates core business rules from external dependencies.
We showcase writing framework-agnostic domain entities, mapping data structures in database repositories, and utilizing dependency injection to keep services fully testable.
