ssujithkumar139/MERN-Contact-Manager ? reverse-engineered prompt

Build me a simple full stack contact manager app where I can add, view, edit, and delete contacts. I want a clean and responsive interface on the front end, with a form for creating and updating contacts, a list or cards view for seeing saved contacts, and easy actions for editing or removing each one.

Please wire it up with a Node and Express backend, a MongoDB database, and REST API routes so the app actually saves data instead of just using local state. Use React for the UI, Axios for requests, and keep the components reusable and easy to follow. Make sure the form handling and state updates feel smooth, and the contact list refreshes properly after changes.

If you need to look up current docs or best practices while building it, go ahead. I want it to be a working MERN app that I can run locally and use right away.
