swaran3564/Sample_mern_app ? reverse-engineered prompt

Build me a simple sample web app with a small frontend page and a Node backend.

I want a basic home page and a cart page that shows a few items, lets me add and remove products, and updates the total as I go. The app should feel like a clean demo project, nothing too fancy, just something easy to open and test in the browser.

Also set up the backend so it can serve the app and handle simple cart data in a straightforward way. If it helps, include a few example API routes for getting products and saving cart changes. Make it easy to run locally and keep the code organized so I can understand it later.

If you need to check current best practices or docs online, go ahead.
