Realtime chat app with rooms
A tutorial-grade Socket.io chat app — rooms, usernames, join/leave notifications, and nothing else. It exists to accompany a YouTube video, not to be a production starting point.
Socket.io usage is clean and minimal, which makes it easy to read for someone learning event-driven messaging. The room isolation logic in utils/users.js is straightforward — no framework magic obscuring how it works. Zero dependencies beyond Express and Socket.io keeps the learning surface small. Runs instantly with npm run dev, which is the right call for a tutorial project.
No persistence — every message vanishes on server restart, making it useless the moment you need any kind of history. No authentication at all; usernames are whatever the client sends. The forks-to-stars ratio (1150/1206) tells you people clone it and immediately start bolting things on because the base is too bare. Last touched mid-2024 and the deps predate that, so you'll hit npm audit warnings on install.
