// the take
A bare-bones multi-user chat room built on Express and Socket.IO, created as a teaching example (the README points straight to a wiki tutorial rather than documenting the app itself). It's for developers learning how Socket.IO rooms and Express routing fit together, not for anyone who wants to run a chat product.
Small enough to read end to end in one sitting, which is exactly the point of a teaching repo. Pairing Express with Socket.IO is still the standard-issue combo for a first real-time app, so the core pattern it demonstrates hasn't gone stale even though the code has.
Last pushed in January 2016 — a decade of Node, Express, and Socket.IO releases behind it, and the bundled dependencies (old Express, old Connect, old formidable) carry known vulnerabilities that were patched years ago. No tests, no auth, no persistence layer visible from the README, so there's nothing here to build a real app on without a rewrite. The README itself is two lines deep and defers all actual explanation to an external wiki, which is a bad sign for anyone evaluating it outside that tutorial's original context.
We read the README, the directory tree and a key source file in October 2026. Nobody pays to be listed. How we judge →
