How to get number of clients in a room

[johnny0614]

in 0.7.x, I can clients() function to retrieve the number of clients in a room. But how can I do it in version 1.0.x ?

I ran into the same problem a about a week ago. I found this answer on SO to be helpful in finding:

io.sockets.sockets

which returns an array of connected clients.

you can also just create your own array and push to it in the callback of .on('connection')

So to answer your question:
13ruce1337 is completly right. To get the number of clients connected just get the length of the array of all clients by

io.sockets.sockets.length

It would be good to be able to get the IDs of every socket in a room. Is there any way to do that?

@download13, that's another question, see #1428 for example.
