Mr-Ahad-Khan/Blinkit-Clone-2 ? reverse-engineered prompt

I want to build a complete grocery shopping website like Blinkit with three separate apps that all work together. The main customer site should let people browse products, search for items, add stuff to their cart, change quantities, see prices and discounts, and browse by categories. Everything needs to look good on phones, tablets, and computers.

I also need a backend API server that handles all the database stuff, user accounts, products, shopping carts, and orders. Use MongoDB for storing everything and make sure there's proper authentication so users can log in securely.

The third part is an admin dashboard where I can add new products, edit existing ones, delete products, and basically manage everything about the store. This should also connect to the same backend.

Use React with Vite for both frontends because it's fast, style everything with Tailwind CSS to keep it modern and responsive, and build the backend with Node.js and Express. Make it so all three apps can run at the same time during development on different ports. Look up current docs if you need to for connecting everything together. The whole thing should feel polished and professional, like an actual grocery delivery app.
