Usage Example

import { AuthProvider } from './contexts/AuthContext';

// Wrap app with AuthProvider
function Root() {
  return (
    <AuthProvider>
      <App />
    </AuthProvider>
  );
}

// Use in components
function App() {
  const [showAuth, setShowAuth] = useState(false);
  const { isAuthenticated, user, logout } = useAuth();

  return (
    <div>
      {isAuthenticated ? (
        <div>
          <p>Welcome, {user?.name}!</p>
          <button onClick={logout}>Logout</button>
        </div>
      ) : (
        <button onClick={() => setShowAuth(true)}>Sign In</button>
      )}

      <AuthModal
        isOpen={showAuth}
        onClose={() => setShowAuth(false)}
        initialView="login"

Testing

All components have comprehensive test coverage:

npm test

Test coverage includes:

• Form validation
• User interactions
• Loading states
• Error handling
• Modal behavior
• Authentication flows

Integration Points

Current

• React Context API for state management
• localStorage/sessionStorage for persistence
• Mock API calls (ready for backend integration)

Ready for Integration

• REST API endpoints
• Stellar blockchain wallet API
• Email service for verification
• OAuth providers (Google, GitHub)
• Protected routes
• Role-based access control

Next Steps

1. Backend Integration

   • Replace mock API calls with real endpoints
   • Implement JWT token management
   • Add refresh token logic

2. Stellar Wallet

   • Integrate Stellar SDK
   • Implement wallet creation
   • Add transaction signing

3. Email Service

   • Configure email provider
   • Design email templates
   • Implement verification emails

4. Social Login

   • Configure OAuth providers
   • Implement callback handlers
   • Link social accounts

5. Enhanced Security

   • Add two-factor authentication
   • Implement rate limiting
   • Add CSRF protection
   • Session timeout handling
