const generateTableQR = async (tableId: string, restaurantId: string) => {
  const menuUrl = `${process.env.NEXT_PUBLIC_BASE_URL}/menu/${restaurantId}?table=${tableId}`;
  
  const qrCodeDataURL = await QRCode.toDataURL(menuUrl, {
    width: 300,
    margin: 2,
    color: {
      dark: '#000000',
      light: '#FFFFFF'
    }
  });
  
  return qrCodeDataURL;
};

​

Menu Management System

// Real-time menu updates
interface MenuItem {
  id: string;
  name: string;
  description: string;
  price: number;
  category: string;
  available: boolean;
  image?: string;
  allergens?: string[];
}

const updateMenuItem = async (itemId: string, updates: Partial<MenuItem>) => {
  // Update database
  await updateMenuItemInDB(itemId, updates);
  
  // Notify all connected clients
  broadcastMenuUpdate(itemId, updates);
};

​

Mobile Optimization

Challenges & Solutions

​

Challenge: Poor Network Connectivity

// Service worker for offline support
self.addEventListener('fetch', (event) => {
  if (event.request.url.includes('/api/menu')) {
    event.respondWith(
      caches.match(event.request).then((response) => {
        return response || fetch(event.request);
      })
    );
  }
});

​

Challenge: Older Customer Demographics

// Large, accessible interface elements
const MenuButton = styled.button`
  min-height: 60px;
  font-size: 18px;
  padding: 16px 24px;
  border-radius: 8px;
  
  @media (max-width: 768px) {
    min-height: 80px;
    font-size: 20px;
  }
`;

​

Challenge: Kitchen Integration

// Kitchen notification system
const sendKitchenNotification = (order: Order) => {
  // Send to kitchen display
  kitchenSocket.emit('new-order', order);
  
  // Send push notification to kitchen staff
  sendPushNotification('kitchen-staff', {
    title: `New Order - Table ${order.tableNumber}`,
    body: `${order.items.length} items`,
    data: { orderId: order.id }
  });
};
