socket.io get rooms which socket is currently in

Question

Is it possible to get rooms which socket is currently in, without calling

io.sockets.clients(roomName)

for every room name and looking for

Answer 1

Version 2.0.3

io.sockets.sockets[yourSocketID].rooms

That equal with

socket.rooms

Answer 2

socket.io 1.7.3 +

var currentRoom = socket.rooms[Object.keys(socket.rooms)[0]];//returns name of room

Answer 3

Socket.io v2.1.1

So make sure you aren't accessing the sockets rooms in the disconnect event like I was, as they have already left the rooms by the time that event is triggered. If you want to do that try it in the disconnecting event - https://github.com/socketio/socket.io/pull/2332/files

Then you can use any of the following:

Object.keys(socket.adapter.rooms)
Object.keys(socket.adapter.sids)
Object.keys(socket.rooms)

Answer 4

1.4.5 version => io.sockets.adapter.rooms[roomname].sockets

Answer 5

From the Socket.IO Room doc:

io.sockets.manager.roomClients[socket.id]

Answer 6

Being sure that socket is in only one room at a time, my solution was:

var currentRoom = Object.keys(io.sockets.adapter.sids[socket.id]).filter(item => item!=socket.id);
