Provides a structured, test-driven approach to implementing new features, endpoints, or use cases in a Python/FastAPI backend using clean architecture, ensuring domain, application, infrastructure, and interfaces align and stay type-safe.
Start by defining a domain entity, create a corresponding use case, implement a repository, and expose it via a FastAPI router.
High-intent search queries and answers about installing and using this skill.
Structure a FastAPI backend using clean architecture by separating domain entities, application use cases, repository protocols, and HTTP interfaces into distinct layers. This Skill automates generating that typed, boundary-enforced layer-by-layer structure for new features end-to-end.
The best way to implement FastAPI endpoints with domain-driven design is starting from domain entities, validating them, then wiring use cases and repository protocols before exposing HTTP routes. This Skill automates that exact TDD workflow to keep domain and infrastructure boundaries type-safe.
Test FastAPI repository protocols with SQLAlchemy and PostgreSQL by running mock-based unit tests for domain logic and integration tests for database infrastructure. This Skill generates both test layers automatically to verify repository boundaries and PostgreSQL integration deterministically.
Yes, you can apply this clean architecture approach to existing Python projects needing new features. The Skill requires typed Python code and domain-driven design patterns, automating use-case creation, repository protocols, and FastAPI router integration for your codebase.
Clean architecture development does not work well without strong typing in Python. This Skill requires typed Python code to preserve domain boundaries and ensure type-safe interactions between application, infrastructure, and interface layers during feature development.
