Faye: Bayeaux protocol Comet server for Node.js

9 Feb 2010

Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic.

James Coglan has ported a Ruby/EventMachine Comet server to offer a new Node.js server on the Bayeux protocol. The project is Faye and you can check out the code on GitHub.

On the client side:

PLAIN TEXT

HTML:

<script type=“text/javascript” src=“/comet.js”></script>
<script type=“text/javascript”>
CometClient = new Faye.Client(‘/comet’);
CometClient.connect();
</script>

PLAIN TEXT

JAVASCRIPT:

CometClient.subscribe(‘/path/to/channel’, function(message) {
// process received message object
});
CometClient.publish(‘/some/other/channel’, {foo: ‘bar’});

And the backend….

PLAIN TEXT

JAVASCRIPT:

var http = require(‘http’)
faye = require(‘./faye’);
var comet = new faye.NodeAdapter({mount: ‘/comet’, timeout: 45});
http.createServer(function(request, response) {
if (comet.call(request, response)) return;
response.sendHeader(200, {‘Content-Type’: ‘text/plain’});
response.sendBody(‘Hello, non-Comet request!’);
response.finish();
}).listen(9292);

Nice!
