So this post follows up from my previous question about setting up a small multiplayer HTML5 game (http://indie-resource.com/forums/viewto ... =65&t=6768) following this tutorial (http://www.youtube.com/watch?v=2_e5NaDX2rs)
the problem is that these tutorials only teaches you how to create a game on localhost but I want to take it online through my website so that it becomes sort of a small online multiplayer game.
So far I have setup a VPS on dreamhost and installed Node JS on the server through SSH using putty. It seems that I can get the node (app.js) started without a problem on my VPS but the game can't seem to load on the website since I guess it has an issue with connecting with socket.io or reaching it.
On my local machine there's an index.html file that contains the line
"<script src="http://localhost:8080/socket.io/socket.io.js"></script>"
which I guess communicates with the server
then I simply run the bat file which starts app.js then everything works fine
So I changed the index file line on my website server to
"<script src="http://mywebsite.com/tutorial/socket.io ... "></script>"
but still no luck
There could be some other reason why but I think it has something to do with that line.
this is how I start the node app.js on putty
[server] $ node /home/server/mywebsite.com/tutorial/app.js
output:
info - socket.io started
warn - error raised: Error: listen EADDRINUSE
Java script console output when I try running the game off my website
Uncaught ReferenceError: require is not defined socket.io.js:12
Uncaught ReferenceError: io is not defined (mywebsite).com/:36
Uncaught TypeError: Cannot call method 'emit' of undefined
Node JS and VPS issue
Re: Node JS and VPS issue
Are you sure that the port you are using, isn't in use?

Re: Node JS and VPS issue
Depends how you installed node.js, as far I understand socket.io, it's not a real file you will find on the filesystem but it will instead have like a fixed URL for your host. No matter what directory your files are.
Try
<script src="http://mywebsite.com/socket.io/socket.io.js></script>
And tell us if that works for you or not. Also make sure you installed the socket.io module correctly

Re: Node JS and VPS issue
You need to specify the port for node.. It does not run on 80. The port number can be found in the app.js which I assume is 8080. You need to specify that in the index file.
Re: Node JS and VPS issue
I used the command npm install socket.io to install socket.io and it created a directory named "node_modules" in my root folder on the VPS. I'm not sure if I installed it incorrectly :\
the script <script src="http://mywebsite.com/socket.io/socket.io.js></script>
and
<script src="/socket.io/socket.io.js></script>
both give the get error
GET http://mywebsite.com/socket.io/socket.io.js 404 (Not Found)
also, my server app.js contains the line
app.listen(8080);
(yeah it is 8080)
and index.html contains
var socket = io.connect('http://localhost:8080');
maybe I should modify these lines too? I'm not sure what port to use on the VPS though.
@hallsofvallhalla how do I specify the port for node? great tutorials btw

Re: Node JS and VPS issue
well you installed socket.io in the wrong location
Just go where your server code (.js file) is, and then use the npm install command.
So if you do app.listen(8080) and you are not behind any proxy like haproxy or such, then your link should be as well loaded from the same port:
http://mywebsite.com:8080/socket.io/socket.io.js
However if you have only node.js and no apache why not run direcly on port 80? And if you have apache it would be smarter to use haproxy or equivalent and use it to split the calls based for example on the domain.
