• End-to-End Encryption: Messages encrypted in transit
• Temporary Storage: Server-side auto-cleanup mechanisms
• Rate Limiting: Anti-spam and DDoS protection
• Input Sanitization: XSS and injection attack prevention

// Example API call for room creation
const createRoom = async () => {
  const response = await fetch('/api/rooms', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json'
    }
  });
  
  const { roomId, roomUrl } = await response.json();
  return { roomId, roomUrl };
};

// Message sending with auto-deletion
const sendMessage = (roomId, message) => {
  const messageData = {
    text: message,
    timestamp: Date.now(),
    ttl: 10000 // 10 seconds
  };
  
  // Send to Firebase with automatic cleanup
  db.collection('rooms')
    .doc(roomId)
    .collection('messages')
    .add(messageData);
};
