[jensysantana]

app.get('/', async (req, res) => {

        io.on('connection', (socket) => {
            socket.on('disconnect', () => {
                   
             });
            socket.emit('messagex', ({ name: 'anyname' }));
        });

});

You shouldn't declare you io.on('connection', ...) in your route:

app.get('/', async (req, res) => {
  // ...
});

io.on('connection', (socket) => {
  socket.on('disconnect', () => {
         
  });
  
  socket.emit('messagex', ({ name: 'anyname' }));
});
