How abdulhanan42/task_managment_app works

This is a FastAPI task-management API with user registration, login and token authentication, plus authenticated task creation, listing, retrieval, updating and deletion. Requests enter through the user or task routers, which validate DTOs and delegate to controllers; controllers query or mutate SQLAlchemy-backed state. Registration also invokes email sending. The graph preserves the central models, DTOs and configuration layer. Several relationships are supported by excerpts; the mail implementation and its external delivery mechanism were not shown.
