Well title says most of it.

I was just reading net.Server class in node js , and i already know about socket.io , it seems like net.server class provides direct access to tcp layer , and we can implement sockets directly using this net.server class , so is socket.io also written using it ?

Or is it written on UDP/Datagram Sockets class:dgram.Socket ?

Thanks

Well u can always have a look at https://github.com/socketio/socket.io as it's open source .

Anyways, from what i infer from source, it's based on http neither net.server nor dgram.Socket You can refer source/lib/index.js

Also this says Socket.IO is a Lightweight protocol that sits on top of HTTP.

Hope it helps
