kushagragoel05/food_ordering_backend_system ? reverse-engineered prompt

Build me a full stack food ordering app that lets people sign up, log in, browse food items, filter them by category, add items to a cart, and place an order that gets saved securely in MongoDB.

I want the front end to feel clean and responsive, with a simple shopping cart experience and a nice way to show food categories and item details. On the backend, set up user authentication and authorization with JWT, plus the API routes needed for viewing food items, managing the cart, and storing orders. Use MongoDB with Mongoose for the data models.

Please make it work as a MERN app, with a React front end and a Node and Express backend. If you need to check current docs for anything, feel free to look them up online. Make sure the whole thing is easy to run locally and includes the basic environment setup I’d need to get started.
