wahabansari/mernstack-final-project ? reverse-engineered prompt

Build me a full stack learning platform called LearnHub.

I want students to be able to sign up, log in, browse courses, search or filter them by category, enroll, and track their progress in the courses they are taking. Instructors should be able to create courses, edit or delete their own courses, and add or remove lessons inside each course. Admins should be able to manage users, manage courses, see simple analytics, and promote users when needed.

Please include secure login with token based auth, role based access, and make sure people only see the pages and actions they are allowed to use. Add a clean home page, course listing, course details, login and register pages, plus separate dashboards for student, instructor, and admin.

Use a modern React frontend and a Node and Express backend with MongoDB. If you need to, look up current docs online as you build. Also include seed data so the app can be tried right away.
