adityanep1/Code-Collaboration-Platform ? reverse-engineered prompt

Build me a real time code collaboration app where people can create or join a room, write code together in the browser, chat with each other, run the code, and save the project for later.

I want it to feel like a simple modern coding workspace, with a clean landing page, room creation and join flow, and an editor that updates live for everyone in the room. Please include user login with secure authentication, since the project mentions JWT, and make sure saved projects can be loaded again later. If you need to check current docs for any library details, go ahead and look them up online.

Use the stack already in the repo, React on the frontend, Express on the backend, MongoDB for storage, Socket.io for live syncing, and Monaco for the code editor. Make it work end to end with a polished, usable interface and sensible defaults.
