How jineshprajapat/chat-application works
This is a React and Express peer-to-peer messaging application. Users authenticate, discover people and conversations, then exchange messages over Socket.IO; conversation and message data are persisted in MongoDB and updates are sent to the relevant clients. The graph includes the documented history, online/unread status, editing and deletion capabilities. Some frontend and socket wiring is inferred from the README and tree rather than sampled source, so uncertain call relationships are omitted.
