Socket.io not working in node.js express

Question

I made an app with express generator, I'm using socket.io in my app but it's not working for me. I use socket.io in bin/www file and after the server created and listened to the port. after load the page that want to connect to the socket, browser's console show this error:

'socket.emmit is not a function'

here's the codes:

var app = require('../app');
var debug = require('debug')('server3:server');
var http = require('http');


var port = normalizePort(process.env.PORT || '8585');
app.set('port', port);


var server = http.createServer(app);

server.listen(port);
server.on('error', onError);
server.on('listening', onListening);


function normalizePort(val) {
  var port = parseInt(val, 10);

  if (isNaN(port)) {
  return val;
  }

  if (port >= 0) {

  return port;
  }

  return false;
};

function onError(error) {
  if (error.syscall !== 'listen') {
    throw error;
  }

  var bind = typeof port === 'string'
    ? 'Pipe ' + port
    : 'Port ' + port;

  switch (error.code) {
    case 'EACCES':
      console.error(bind + ' requires elevated privileges');
      process.exit(1);
      break;
    case 'EADDRINUSE':
      console.error(bind + ' is already in use');
      process.exit(1);
      break;
    default:
      throw error;
  }
};


function onListening() {
  var addr = server.address();
  var bind = typeof addr === 'string'
    ? 'pipe ' + addr
    : 'port ' + addr.port;
  debug('Listening on ' + bind);
};



var io = require('socket.io').listen(server);

io.on('connection', function(socket){
  console.log('socket is on...');

});

It's the summary of my socket codes. the main codes are here. anyway it's not working!

What exactly isn't working? What request do you send to your server and what exactly happens to that request? If this is a socket.io question, then please show us the socket.io code that you use to connect and show us exactly what the browser network tab shows when you try to connect. — jfriend00, Oct 06 '17 at 00:39
@jfriend00 i update the post. browser have an error. the error is: socket.emmit is not a function — Amirreza zahed, Oct 06 '17 at 14:32
`socket.emmit` is not spelled correctly. It should be `socket.emit` — jfriend00, Oct 06 '17 at 14:52

The proper name of the method is socket.emit (single "m").
