Inspiration I’ve always loved the simplicity of tools like Google Docs, where multiple people can work together in real time. But when it comes to coding, most collaboration still relies on screen sharing or slow pull requests. I wanted to create a space where developers can edit code together instantly, without needing complicated setups.
How I Built It The project combines several modern web technologies:
Frontend: Built with React and TypeScript for a smooth, responsive user interface.
Backend: Node.js with Express to handle API routes and authentication.
Real-Time Collaboration: WebSockets (Socket.IO) to sync code changes across all clients instantly.
Code Storage: Changes are persisted in a database (MongoDB) so edits aren’t lost.
Authentication & Invites: Users can create sessions and invite others via unique shareable links.
What I Learned Working on this project taught me:
How to efficiently broadcast updates to many clients without overwhelming the server.
The importance of conflict resolution when multiple people edit the same code.
How to design a clean, intuitive UX for collaborative environments.
Challenges I Faced Synchronization: Keeping everyone’s editor perfectly in sync, even with network delays or reconnects.
Merge Conflicts: Deciding which edits take priority when users type at the same time.
Scalability: Making sure the server could handle multiple active sessions without lag.
What’s Next I plan to add:
Syntax highlighting for more languages.
In-editor chat to discuss code changes.
Version history to roll back edits.
