Trying to Implement Node.js and Socket.io on dedicated server -
recently, have been experimenting node.js , socket.io. successfully, have been able implement these on localhost. use functionality on dedicated server. hosting server own home , cannot node , socket run outside of localhost. importance of can use 2 different computers while testing out site. here code follows:
app.js: var app = require('express')() , server = require('http').createserver(app) , io = require('socket.io').listen(server); server.listen(80); app.get('/', function (req, res) { res.sendfile(__dirname + '/index.html'); }); io.sockets.on('connection', function (socket) { socket.emit('news', { hello: 'world' }); socket.on('my other event', function (data) { console.log(data); }); });
index.html: <script src="http://localhost:8080/socket.io/socket.io.js"></script> <script> var socket = io.connect('http://localhost:8080'); socket.on('news', function (data) { console.log(data); socket.emit('my other event', { my: 'data' }); }); </script> these samples taken directly off socket.io site. works on localhost, not externally. cannot use on computer. advised change
var socket = io.connect('http://localhost:8080');var socket = io.connect('http://mydomain.com:8080'); uncaught referenceerror: io not defined mydomain.com/:3 http://mydomain.com/socket.io/socket.io.js mydomain.com/:1 even on main server computer. im using osx server mac mini btw.
any advice appreciated:
it looks you're listening on port 80 instead of 8080, , need point script block server, try
<script src="http://localhost:8080/socket.io/socket.io.js"></script> needs be
<script src="http://mydomain.com:80/socket.io/socket.io.js"></script> or better yet
<script src="/socket.io/socket.io.js"></script> if doesn't work, make sure check errors under network tab of debugger window (presuming you're using chrome) make sure you're loading socket.io.js file correctly.
