I'll be starting to work on a MERN project. Usually, there's two folders in the root, one for frontend and one for backend. Before I start working, I want them in github to track them, check commits and progress etc.

My question is, do I maintain two separate repos for this project? One frontend and one backend? Or the entire root with both the folders can be added to a single repo? In that case, how do I connect both folders together in Vercel/Render/Netlify

I've heard of Render being used more in MERN deployments so you can consider that
