🛠️ Technical Highlights

Real-time Implementation

Our custom WebSocket implementation handles differential synchronization between clients with minimal bandwidth usage and optimistic UI updates.

// Example of real-time cursor tracking implementation
const updateCursorPosition = useCallback(
  throttle((position: CursorPosition) => {
    if (!socket || !user) return;
    
    // Send position only if it changed significantly
    if (Math.abs(position.x - lastPosition.current.x) > 5 || 
        Math.abs(position.y - lastPosition.current.y) > 5) {
      socket.emit('cursor:update', {
        position,
        userId: user.id,
        documentId: currentDocument.id
      });
      lastPosition.current = position;
    }
  }, 50),
  [socket, user, currentDocument]
);

Row-Level Security

Supabase RLS policies ensure users can only access authorized content:

-- Example of row-level security policy
CREATE POLICY "Users can only view their own documents" ON documents
  FOR SELECT USING (
    auth.uid() IN (
      SELECT user_id FROM workspace_users
      WHERE workspace_id = documents.workspace_id
    )
  );

Performance Optimizations

• Server Components for reduced client JS
• Selective hydration for interactive elements
• Chunked data loading with Suspense boundaries
• Efficient WebSocket message batching
