使用socket.io将客户端连接到服务器

Question

I have a node.js basic server as follow:

app.js file:

var express = require('express');
config = require('./config/config');

var app = express();
require('./config/express')(app, config);
var server = require('http').Server(app);
server.listen(config.port,function () {
console.log('Express server listening on port ' + config.port);
});
module.exports = server;

my port is 8001.

and a deafult.ts file:

import express = require('express');
var server = require('../../app');
var router = express.Router();

export = function (app) {
app.use('/', router);
};

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

var io = require('socket.io')(server);
io.on('connection', function (socket) {
console.log("connected" + socket.id);
});

I have another project, my client and i want to open a socket connection to the server, but i failed to do so. all examples i've seen using an index.html file inside the node project (indeed works). i tried adding my client:

<script src="https://cdn.socket.io/socket.io-1.4.5.js"></script>
<div>
<button ng-click="io.connect('http://localhost:8001')">hi</button>
</div>

but i don't get the "connected" log .

appreciate any help.

This client should give you a persistent socket connection :

<script src="https://cdn.socket.io/socket.io-1.4.5.js"></script>
<script>
    var socket = io.connect(http://localhost:8001);
    // attach your events here
</script>
