Chai aur JavaScript Backend in Hindi (Chai aur Code)

Hitesh Choudhary's backend series in Hindi teaches Node.js and Express the way production projects are built. It opens with a backend roadmap, deploying code and connecting frontend and backend with proxies and CORS, then moves to data modelling with Mongoose (including e-commerce and hospital examples), a professional project setup, connecting MongoDB, custom API responses and error handling, user and video models with JWT, file uploads with Multer, HTTP basics, routers and controllers, and testing with Postman. It suits learners who know JavaScript and want backend skills.
