Socket.IO basic example not working

Question

I\'m 100% new to Socket.IO and have just installed it. I was trying to follow some examples, and can get the server side running but I can\'t seem to get the client side con

Answer 1

In same origin policy, localhost:8090 and localhost are not the same origin (different port), so localhost/index.html cannot connect to socket.io on localhost:8090.

One option is to make index.html on localhost:8090 (see code below). Then you just put "index.html" into the same directory of your server script, start the server and type localhost:8090 in your browser.

var fs = require('fs');

server = http.createServer(function(req, res){
    fs.readFile(__dirname + '/index.html', 'utf-8', function(err, data) { // read index.html in local file system
        if (err) {
            res.writeHead(404, {'Content-Type': 'text/html'});
            res.end('
Page Not Found
');
        } else { 
            res.writeHead(200, {'Content-Type': 'text/html'});
            res.end(data);
        }
    });
});
