Question

I want to use Node.js run as a back-end server to serve front-end socket.io request.

The samples I found, seems can only run pages from Node.js server.

<script src="/socket.io/socket.io.js"></script>

The above js include is served by Node.js, how to include it if the front-end is a different application (e.g. PHP or static pages) ? Do I need to include all the dependent socket.io js libraries to make it work?

Answer 1

I’m currrently running apache/php alongside node.js/socket.io
If this is what you’re trying to do, you can do it by serving socket.io on a different port than what apache is serving on (assumed 80).

In node.js, initialize the socket.io listener on a port 8080 for example:

var io = require('socket.io').listen(8080);

I believe, by default, socket.io will also serve its static client side files conveniently for you, such that in you html, you can:

<script src="http://yourhost:8080/socket.io/socket.io.js"></script>

Hope that helps.
