vikaspareek-vp/inventory-management-system ? reverse-engineered prompt

Build me a full stack inventory management app for a small business with separate admin and staff logins. I want users to be able to sign up, log in, update their profile, and change their password, with protected pages so only the right people can access the right features. The app should let admins manage products, categories, suppliers, and stock levels, while staff can view inventory and update stock where allowed.

I want a clean responsive dashboard with charts and basic reports so it’s easy to see inventory levels at a glance. Make the frontend in React with a modern, simple interface, and have it talk to an Express and MongoDB backend through API routes. Use JWT auth, role based access, and show helpful success and error messages. If you need to check current library docs while building, go ahead and look them up online.
