Python DDD

Python Domain-deriven Design | Open source ( 300+)

GitHub - qu3vipon/python-ddd: Python DDD pattern example using FastAPI
I've adopted the DDD pattern for my recent FastAPI project. DDD makes it easier to implement complex domain problems. Improved readability and easy code correction have significantly improved productivity. As a result, stable project management has become possible. I'm very satisfied with it, so I'd like to share this experience and knowledge.
