title: socket.io - io.sockets.adapter object?
body: <p>I'm experimenting with socket.io and trying to build a multi-room chat app. The guide I'm following is out of date using pre 1.0.0 socket.io. </p>
  
  <p>I'm trying to find a list of connected clients in a given room. Googling around shows that I have to use the adapter. However, I cannot find the documentation for it anywhere. I searched for it in the git-hub doc but search didn't return any information on adapter. <a href="https://github.com/socketio/socket.io-client/blob/master/docs/API.md" rel="nofollow noreferrer">https://github.com/socketio/socket.io-client/blob/master/docs/API.md</a></p>
  
  <p>Can someone point me in the right direction and where I can read more about adapter and associated methods on it? Also if you can provide the most up to date documentation for socket.io I'd greatly appreciate it. Thank you.</p>
