I’m working on an online note-taking app using Next.js, Shadcn, and Socket.io for real-time collaboration as final year project. The main objectives are:

-Users can perform CRUD operations on notes.
-Multiple users can collaborate and edit notes in real-time.
-The app needs to be deployed.

My problem now is how to save the note in db as user keep editing it(like in google docs) ,or should i go with manual save button.What is the best way to it so when i implement real time collaboration it won't be a problem.should i use socket for this too?

Plus:I am kind of beginner, it is feasible to complete this project in two week and deploy it in some free available paln. Does vercel deployment in hobby plan support socket like thing?

Need suggestion ,help ,solution whatever i can get to complete this project.I am lost.
