Usman3432/Ecommerce-Ushop — reverse-engineered prompt

Build me a simple full stack online shop app using JavaScript, with a backend API and a frontend that actually feels usable. I want products stored in MongoDB, and the backend should let me create, edit, delete, and fetch products cleanly. On the frontend, make a basic store experience where someone can browse products, view details, and see prices and images, plus an admin style screen for managing the product catalog.

Please keep it practical and easy to run locally, with sensible routes, validation, and error handling. If auth makes sense for protecting product management, add a simple version of that too, but do not turn it into a huge enterprise app. I mostly want a clean ecommerce starter that covers product management well and has the frontend connected to the backend properly.

Make the code organized and readable, and add a short setup guide with environment variables and how to start both sides. If anything is unclear, look up current docs online and choose the simplest solid approach.
