node.js - How to get room's clients list in socket.io 1.0

Question

I can get room's clients list with this code in socket.io 0.9.

io.sockets.clients(roomName)

How can I do this in socket.io 1.0?

Consider this rather more complete answer linked in a comment above on the question: https://stackoverflow.com/a/24425207/1449799

The clients in a room can be found at

io.nsps[yourNamespace].adapter.rooms[roomName]

This is an associative array with keys that are socket ids. In our case, we wanted to know the number of clients in a room, so we did Object.keys(io.nsps[yourNamespace].adapter.rooms[roomName]).length

In case you haven't seen/used namespaces (like this guy[me]), you can learn about them here http://socket.io/docs/rooms-and-namespaces/ (importantly: the default namespace is '/')
