[Vuejs]-Socket.io duplicate emit on second window

✅

It’s because you’re creating a connection listener every time someone visits the '/' route. Try moving the socket-io code outside of the '/' route function.

As Eric mentioned, move your connection listener outside of the / route in order to prevent it from getting created every time someone visits the page.

router.get('/', function(req, res, next) {
 res.render('index', { title: 'Express' });
});

io.on('connection', function(socket) {
  socket.on('chatMessage', function(msg){
    io.emit('chatMessage', msg);
  });
});
