I think you're ask too much from React, whose goal is building single page applications.

If you don't want big bundles because the initial loading time worries you; You will have to make a React application per folder; then make sure every link points to the right URL. This will add more complexity because is more deployments, duplicate code, etc.

I highly recommend React router, I think you should check it out... https://reactrouter.com/en/main/start/overview

React Router enables "client side routing".

• When the URL is yourDomain.com/ the view would be your home.jsx component
• When the URL is yourDomain.com/edit the view would be your edit.jsx component
• When the URL is yourDomain.com/view the view would be your view.jsx component

And many others.
