套接字IO和MongoDB服务器

Question

Today i installed MongoDB and Socket IO + Nodejs on Ubuntu (15.10)

Everything is installed correctly, but my server.js (making a realtime chat) does not make any connection, This is the script i have:

var mongo = require('mongodb').MongoClient, client = require('socket.io').listen(8080).sockets;

client.on('connection', function(socket){
console.log('Someone has connected!');
});

Just nothing happends:

Can anyone help me? THanks alot!

From a tutorial i had to add

<Script src="http://127.0.0.1/socket.io/socket.io.js"></script>

But it says it cant find it altho its installed.

my Index:

Answer 1

1. Make sure socket.io is installed

    npm install socket.io 

2. As your server is not setup static files you should change the script src in your html to:

    <script src="https://cdn.socket.io/socket.io-1.4.5.js"></script>
