$ sudo cpan Stardust

Running the COMET server on port 5555:

$ stardust.pl --port=5555 --base=/comet

Making pages subscribe to channel 'foo':

<script>
  var uniqueId = Math.random().toString();
  $.ev.loop('/comet/channel/foo/'+uniqueId, {
    "*": function(ev) {
    }
  });
</script>

Posting JSON messages to channel 'foo':

curl -d 'm={ "type": "TestMessage", "data": [3, 2, 1] }' \
  http://localhost:5555/comet/channel/foo

DESCRIPTION

Stardust is a simple COMET server that can be integrated alongside existing web applications.

CONCEPTS

Message

Messages are just abritrary JSON objects.

Channel

Channels are where messages travel trough.

API

Communication with the Stardust COMET server uses JSON over HTTP. The following URLs represent your API.

GET /

This is just a little informational JSON-encoded data that tells you what version of the Stardust server you're using.

GET /channel

This returns a list of all the channel names currently in use as a JSON-encoded array of strings.

GET /channel/([\w+]+)

This returns info about the specified channels as a JSON-encoded array of objects.

POST /channel/([\w+]+)

This allows one to send a message to the specified channels.

Parameters:

m

an JSON-encoded object. This parameter may be repeated if you want to send more than one message per POST request.

GET /channel/([\w+]+)/stream/([.\d]+)

Long poll on this URL to receive a stream of messages as they become available. They will come back to you as a JSON-encoded array of objects.
