How workingonxyz-commits/auth-app-backend works
This Spring Boot backend exposes user registration and user-management APIs. Registration passes from the auth endpoint through AuthService into the shared user-creation service; CRUD endpoints call that user service directly. The service validates and maps DTOs, then reads or writes users through the JPA repository. The entity models persistent user and role data. The README is empty, and sampled files do not establish security/configuration or database deployment details, so those are not drawn.
Main entry points: UserServiceImpl.java User service · UserRepository.java User repository · AuthController.java Auth endpoint · UserController.java User endpoints
