## Routing Implementation

### Route Structure

```typescript
routes/
├── index.tsx          # Main router configuration
├── PrivateRoute.tsx   # Protected route wrapper
└── routes.ts          # Route definitions

// Route Configuration
const routes = {
  public: {
    home: '/',
    login: '/auth/login',
    signup: '/auth/signup',
  },
  private: {
    dashboard: {
      root: '/dashboard',
      ask: '/dashboard/ask',
      upload: '/dashboard/upload',
      resources: '/dashboard/resources',
      history: '/dashboard/history',
      settings: '/dashboard/settings',
    }
  }
}
```

### Route Guards

- Implementation of protected routes using `PrivateRoute` component
- Authentication state management
- Role-based access control

## Component Architecture

### Layout Components

- **DashboardLayout**: HOC for dashboard pages with sidebar and header
- **AuthLayout**: HOC for authentication pages
- **PublicLayout**: HOC for public pages

### Feature Components

1. **Auth Module**

   - LoginForm
   - SignupForm
   - PasswordReset

2. **Dashboard Module**

   - QuestionForm
   - MaterialUploader
   - ResourceViewer
   - HistoryTracker

3. **Common Components**
   - Button
   - Input
   - Card
   - Modal
   - Loader

## State Management

- React Context for global state
- Custom hooks for shared logic
- Local component state for UI

## API Integration

- Axios for HTTP requests
- Service layer for API calls
- Request/Response interceptors
- Error handling middleware

## Error Handling

- Global error boundary
- Form validation
- API error handling
- User feedback system

## Performance Optimizations

- Route-based code splitting
- Lazy loading of components
- Memoization of expensive computations
- Image optimization

## Security Measures
