Is it possible to have a client leave a room using just the socket ID with the io object?
io.sockets(specificSocketID).leave('sampleroom');
The documentation mentions using the leave method with the socket, but I am looking for a way to achieve this with the io object instead. Can anyone provide guidance on how to make this work?
To keep track of incoming sockets, store them in a custom object.
var socketList = {};
io.on('connection',function(socket){
socketList[uniqueID] = socket;
io.on('disconnect',function(){
delete socketList[uniqueID];
});
});
//subsequently, easily access and interact with specific sockets by their IDs
socketList[uniqueID].join('specialRoom');
socketList[uniqueID].leave('specialRoom');
One approach, suggested by @tresdin, is to save socket ids along with the io object, but in reality, we may not require it. Instead, we can simply utilize a specific socket id like
io.sockets.sockets[specificSocketID].leave('sampleroom');
If the version is above 3.0
io.sockets.sockets.get(specificSocketID).exit("sampleroom");
If the version is below 3.0
io.sockets.sockets[specificSocketID].exit("sampleroom");
