PuSH subscriber as Connect middleware

This module provides a PuSH
(pubsubhubbub) subscriber. This is a
object with methods for subscribing to, and unsubscribing from, topics
on PuSH hubs.

The object gives you a middleware you can use with
Connect or
Express; provided you host it
somewhere suitably accessible via HTTP, it will then accept HTTP
updates from the hubs and emit them as events.

var subscriber = require('snrub')
.createSubscriber({'host': 'example.com:8000'});
var app = connect(subscriber.middleware());

subscriber.subscribe('http://pubsubhubbub.appspot.com', // hub
'http://blog.cloudfoundry.com/feed');
subscriber.on('subscribe', function(topic) {
console.log("Subscribed to " + topic;)
});
subscriber.on('update', function(topic, content) {
console.log("Content from " + topic);
console.log(content);
});

app.listen(8000); // pretending we are on host example.com
