1. Server 예시

var io = require('socket.io').listen(8001);
io.sockets.on('connection', function (socket){
var room_id;
socket.on('joinRoom',function(data){
room_id = data;
socket.join(room_id); //룸입장
console.log('JOIN ROOM LIST', io.sockets.adapter.rooms);
});
socket.on('leaveRoom',function(){
socket.leave(room_id);//룸퇴장
console.log('OUT ROOM LIST', io.sockets.adapter.rooms);
});
socket.on('sendMsg',function(data){
io.sockets.in(room_id).emit('msgAlert',data);//자신포함 전체 룸안의 유저
//socket.broadcast.to(room_id).emit('msgAlert',data); //자신 제외 룸안의 유저
//socket.in(room_id).emit('msgAlert',data); //broadcast 동일하게 가능 자신 제외 룸안의 유저

socket.on('disconnect', function(){
console.log('NOT USER DISCONNECT : ', socket.id);
console.log('ROOM LIST', io.sockets.adapter.rooms);
