This is a full-stack web application starter kit combining Angular (frontend) and Spring Boot (backend) with JWT-based authentication. The system provides user registration, login, role-based access control (USER/ADMIN), and protected API endpoints. The frontend communicates with the backend via RESTful APIs, with authentication handled through JWT tokens stored in cookies. The architecture follows a standard client-server pattern with clear separation of concerns: Angular handles UI presentation and user interactions, while Spring Boot manages business logic, data persistence, and security. Key features include route guards for client-side protection, custom JWT filters for server-side authentication, and centralized service layers for API communication.
