saurabh-2934/task-management-mern ? reverse-engineered prompt

Build me a simple task management app where I can create tasks, edit them, mark them as done, and delete them when I no longer need them.

I want a clean web app with a frontend and a backend, and the data should be saved properly so tasks still show up after refreshing the page. Please make it feel polished and easy to use, with a basic layout that works well on desktop and mobile.

If it makes sense, include simple filtering like all, active, and completed tasks, plus a clear way to see what I still need to do. Use a modern, straightforward design, and keep the code organized so it is easy to understand and extend later.

If you need to look up current docs online for anything, go ahead and do that.
