shivanivaddar/mern-student-app ? reverse-engineered prompt

Build me a simple student management app for a MERN stack workshop project.

I want a React frontend and an Express and Node backend with MongoDB, where I can add, edit, delete, and view students. Each student should have roll number, name, branch, email, phone, and semester. The page should show a form for entering student details and a table underneath that lists all students, with buttons to edit or remove each row. Make it look clean and responsive so it works well on mobile too.

Please wire the frontend to the backend with API calls, and set up the basic CRUD routes for students. If you need current setup details or best practices for the libraries, look up the latest docs online. Keep it simple, beginner friendly, and ready to run locally with a backend on one port and the frontend on another.
