anas-work-7/Difference-Backend-video ? reverse-engineered prompt

Build me a backend project that feels like a practical learning playground for a modern web app, with a bunch of small examples all working together in one place. I want it to cover the basics like HTTP, Express, routing, forms, cookies, sessions, flash messages, logging, CORS, and error handling, then move into MongoDB with CRUD, relationships, references, and common operators. Add authentication with JWT and Google login, file uploads with Multer and image storage, plus email sending, Redis, sockets for real time updates, and Razorpay for payments. It should be easy to test with Postman and use clean example endpoints so I can see how each piece works. If anything depends on current setup details, look up the latest docs online and wire it up in a simple, working way. I mainly want something I can run, explore, and learn from without having to piece everything together myself.
