我在Webstorm中创建默认的Express Node.js项目

如何将 Socket.io 添加到WebStorm Project Structure

的项目结构中

我尝试将Socket.io添加到文档中编写的index.js（/ routes）和chat.html（/ routes）中，但是出现了这些错误Errors

var express = require('express');
var router = express.Router();
var http = require('http').Server(express); //add 
var io = require('socket.io')(http); //add 

router.get('/chat', function(req, res) {
    res.sendFile(__dirname + '/index.html');
});

io.on('connection', function(socket){ //add
    socket.on('chat message', function(msg){
        io.emit('chat message', msg);
    });
});

module.exports = router;

<!doctype html>
<html>
  <head>
    <title>Socket.IO chat</title>
    <style>
      * { margin: 0; padding: 0; box-sizing: border-box; }
      body { font: 13px Helvetica, Arial; }
      form { background: #000; padding: 3px; position: fixed; bottom: 0; width: 100%; }
      form input { border: 0; padding: 10px; width: 90%; margin-right: .5%; }
      form button { width: 9%; background: rgb(130, 224, 255); border: none; padding: 10px; }
      #messages { list-style-type: none; margin: 0; padding: 0; }
      #messages li { padding: 5px 10px; }
      #messages li:nth-child(odd) { background: #eee; }
      #messages { margin-bottom: 40px }
    </style>
  </head>
  <body>
    <ul id="messages"></ul>
    <form action="">
      <input id="m" autocomplete="off" /><button>Send</button>
    </form>

    <script>
      $(function () {
        var socket = io();
        $('form').submit(function(){
          socket.emit('chat message', $('#m').val());
          $('#m').val('');
          return false;
        });
        socket.on('chat message', function(msg){
          $('#messages').append($('<li>').text(msg));
          window.scrollTo(0, document.body.scrollHeight);
        });
      });
    </script>
  </body>
