🔧 Technical Implementation

Technology Stack

  • React: 18.2+ (functional components with hooks)
  • TypeScript: 5.0+ (full type safety)
  • React Router: 6.0+ (SPA routing)
  • Tailwind CSS: 3.4+ (utility-first styling)
  • Vite: 5.0+ (build tool)
  • date-fns: Date formatting
  • @heroicons/react: Icon library
  • recharts: Charts (future use)

Architecture Patterns

  1. Context API for State Management

    • AuthContext for global authentication state
    • useAuth hook for accessing auth state

  2. Protected Route Pattern

    • Route guards check authentication
    • Admin role verification
    • Automatic redirect to login

  3. Nested Routing

    • Public routes outside protected area
    • Protected routes within AdminLayout
    • Centralized route configuration

  4. Component Composition

    • Small, focused components
    • Reusable UI elements
    • Separation of concerns

  5. API Integration

    • Centralized fetchAPI utility
    • Type-safe responses
    • Error handling with APIError
    • Token injection via headers

Security Measures

  • ✅ JWT token authentication
  • ✅ Admin role verification
  • ✅ Protected routes with guards
  • ✅ Session validation on mount
  • ✅ Automatic logout on invalid token
  • ✅ No PHI in URLs
  • ✅ HTTPS recommended for production
  • ✅ Token stored in localStorage
