Socket.io Connected User Count

Question

I finally got socket.io to work properly, but I have encountered a strange problem.

I am not sure if this is the best way, but I am using:

io.sockets.cli         


        

Answer 1

I have found the way to figure it out in version 1.3.7. There are three methods as follows：

1. io.engine.clientsCount
2. io.sockets.sockets.length
3. Object.keys(io.sockets.connected).length

Hope these can help someone with the same issue.:)
