## API Integration Ready

### Features
- Mock data built-in for immediate testing
- Type-safe API routes
- SWR hooks for automatic caching and revalidation
- Error handling included
- Response standardization across all endpoints

### How to Connect Backend
1. Update API routes in `/app/api/` to replace mock data with real database calls
2. Keep the response structure matching the defined types
3. Update environment variables for database connections
4. Deploy with backend service

## Data Models

### Investment
- ID, name, amount, ROI, status, boat reference, investor

### Boat
- ID, name, type, capacity, status, BMU, crew size

### Catch
- ID, trip reference, fish type, quantity, quality, price, storage

### Marketplace Item
- Fish type, quantity, price, seller, status, buyer, date

### User
- ID, name, email, role, status, join date, last login

### Expense
- ID, category, description, amount, date, boat, status

### BMU
- Name, location, members, active boats, revenue, manager

### Storage Facility
- Name, location, capacity, stock, temperature, humidity, status

## Getting Started

1. **Start Development Server**
   ```bash
   pnpm dev
   ```

2. **Access the Application**
   - Landing page: http://localhost:3000
   - Dashboard: http://localhost:3000/dashboard
   - All dashboards are accessible via sidebar navigation

3. **Mock Data**
   - All pages load with generated mock data automatically
   - No authentication required (add as needed)
   - Data persists during session

4. **Modify & Extend**
   - Edit pages in `/app/dashboard/[section]/page.tsx`
   - Update types in `lib/types.ts`
   - Add new endpoints by creating new route files in `/app/api/`

## API Response Format

All API routes follow this standard format:

```json
{
  "success": true,
  "data": { /* endpoint-specific data */ },
  "timestamp": "2024-01-15T10:30:00Z"
}
```

Specific endpoints return:
- `/investments` - `{ investedAmount, availableFunds, returns, packages }`
- `/boats` - `{ boats: [] }`
- `/marketplace` - `{ items: [] }`
- `/analytics` - `{ revenue, expenses, profit, monthlyData }`
- etc.

## Customization

### Add New Dashboard
1. Create new folder in `/app/dashboard/[name]/`
2. Create `page.tsx` with your dashboard content
3. Add route to sidebar navigation in `components/dashboard/sidebar.tsx`
4. Create corresponding API endpoint if needed

### Update Mock Data
Edit `lib/mock-data.ts` to modify generated data for any dashboard

### Change Styling
- Global styles: `app/globals.css`
- Component overrides: Edit individual components in `components/dashboard/`
- Theme colors: Update Tailwind configuration

## Performance Optimizations
- Image optimization for charts and visualizations
- Server-side data fetching where possible
- Client-side caching with SWR
- Lazy loading for large tables
- Responsive design for all screen sizes

## Security Considerations
- Add authentication before production deployment
- Implement role-based access control (RBAC) in API routes
- Add input validation and sanitization
- Use HTTPS for all API calls
- Implement rate limiting
- Add audit logging for sensitive operations

## Deployment
Ready to deploy to Vercel:
```bash
vercel deploy
```

Or to any Node.js environment with the standard build process.

## Support & Documentation
All dashboards include:
- Real-time data visualizations
- Interactive tables with sorting/filtering
- Status indicators and badges
- Trend analysis
- Performance metrics
- User-friendly navigation

## Next Steps
1. Connect to your backend database
2. Replace mock data with real API calls
3. Add user authentication
4. Configure payment processing
5. Set up monitoring and alerts
6. Deploy to production
