DevTinder is a teaching project that mimics Tinder. Users sign up, create profiles, swipe on others, match with mutual likes, and chat in real time. It is a real Node.js backend.
Node.js, Express, MongoDB, Mongoose, JWT for auth, Socket.IO for real-time chat. The frontend is React. The backend is a well-structured monolith.
User A swipes right on User B and a ConnectionRequest with status "interested" is created. If User B has already swiped right on User A, a Connection (match) is created. Otherwise, nothing happens yet.
