🔧 Architecture Features

Separation of Concerns

Clear separation between frontend presentation layer, backend business logic, and data persistence layer for maintainable code.

Scalable Design

Modular architecture allows for easy scaling of individual components and addition of new features without affecting existing functionality.

Security First

JWT-based authentication, role-based access control, CORS protection, and input validation at multiple layers.

Responsive Design

Mobile-first approach with Material-UI components ensuring consistent experience across all devices and screen sizes.

Performance Optimized

Vite for fast development builds, code splitting, lazy loading, and optimized production bundles for quick load times.

Type Safety

Full TypeScript implementation ensures type safety, better IDE support, and reduced runtime errors.

🔐 Authentication Flow

1. User submits login credentials 2. Backend validates credentials 3. JWT token generated and returned 4. Frontend stores token in localStorage 5. Token included in API request headers 6. Backend validates token for protected routes 7. User data returned if token valid
