A tutorial-style React + Socket.IO chat app. Two directories, client and server, wired together with a few dozen lines each. Aimed at developers learning how real-time messaging works, not at anyone building something they'll ship.
Socket.IO handles reconnection and fallback to long-polling automatically, so the demo works reliably without any manual connection management. The client/server split is clear — no framework magic obscuring where the socket events actually live. Minimal enough that you can read the whole thing in one sitting and actually understand it.
node_modules committed to the repo, which is a basic hygiene failure and inflates the repo size with hundreds of files that have nothing to do with the code. No rooms, no username persistence, no message history — fine for learning, but a cliff-edge if you try to build on it. No authentication whatsoever on the socket connection, so anyone who finds your server URL can send messages. Last touched April 2023 with no signs of maintenance.
