sumoksh1/GroceryApp ? reverse-engineered prompt

Build me a simple grocery app where people can keep track of what they need to buy and what they already have.

I want a clean web app with a frontend and a backend, so users can add grocery items, edit them, mark them as bought, and remove them when they are no longer needed. It should feel easy to use on desktop and mobile, with a straightforward layout that makes it quick to scan a shopping list.

Please set up the full app so the data saves properly instead of disappearing on refresh. If it helps, use a modern React style frontend and a Node and Express backend with a database. Add the basics like creating items, updating them, deleting them, and showing the current list clearly.

Keep the UI simple and practical, and make sure the project runs smoothly from the root with clear setup instructions. If you need to look up current best practices or docs online, go ahead and do that.
