samhita2003/Notes-App ? reverse-engineered prompt

Build me a full stack notes app where people can sign up, log in, and safely manage their own private notes.

I want users to be able to create, edit, delete, search, and pin notes, and also add tags to organize them. The app should show the signed in user’s info, keep notes separated so each person only sees their own content, and handle bad logins or invalid requests in a friendly way. The notes page should feel clean and responsive on both desktop and mobile, with a simple dashboard style interface that makes it easy to add a new note, search by title, content, or tags, and keep important notes pinned at the top.

Use a modern React frontend with a Node and Express backend and MongoDB for storage, with JWT based authentication and password hashing. If you need to check current docs or best practices for any libraries, look them up online first.
