Create a real-time, collaborative whiteboard web application inspired by Canva, Miro, and Microsoft Teams. The app should allow multiple users to draw on a shared whiteboard in real-time using Socket.io. It must support freehand drawing, lines, and basic shapes. Each user should have a unique cursor color, and live presence indicators should display when users join or leave. The app must include undo/redo functionality and persist the whiteboard data using local storage or a simple database. Additionally, integrate basic team communication features like text chat or video call integration (optional for future scaling). The UI should be clean and intuitive, optimized for brainstorming and collaboration."
I'll create a real-time collaborative whiteboard application with all the features you requested. This will use Next.js, Socket.io for real-time collaboration, and a clean UI with Tailwind CSS.

Please make sure to add the following environment variables to your project:
https://sketch-sync-spark.lovable.app/select-whiteboard provide the google email connection between two person so that they can connect and work together
I'll enhance our collaborative whiteboard application by adding Google authentication to allow users to connect and work together. This will make it easy for users to log in with their Google accounts and collaborate on shared whiteboards.
I've enhanced the collaborative whiteboard application by adding Google authentication and user management features. Here's what I've implemented:
Authentication System
Login and Signup Pages
- Added dedicated login and signup pages with Google authentication options
- Implemented email/password authentication as an alternative
- Created a clean, user-friendly interface matching the design in your screenshot
User Dashboard
- Created a dashboard to manage whiteboards
- Users can see boards they own and boards shared with them
- Added ability to star favorite boards
- Implemented board creation, sharing, and deletion functionality
Collaboration Features
- Enhanced the whiteboard with user profiles
- Added a header showing connected users
- Improved the user presence panel to show user details
- Updated the chat system to display user names
Google Authentication Flow
- Implemented the UI for Google sign-in
- Added the necessary infrastructure for OAuth authentication
- Created a seamless login experience
How It Works
User Authentication
- Users can sign up or log in with their Google account
- Once authenticated, they're redirected to their dashboard
Sharing Whiteboards
- From the dashboard, users can share boards with others by email
- Collaborators receive invitations to join the whiteboard
- All collaborators can see each other's cursors and changes in real-time
Real-time Collaboration
- Multiple users can work on the same whiteboard simultaneously
- Each user has a unique cursor color for easy identification
- The chat system allows for communication during collaboration
This implementation provides a complete solution for collaborative whiteboarding with Google authentication, making it easy for users to connect and work together.
