mod_pubsub_feeds: Don't skip publishing items after an existing one I encountered a feed which was backwards, such that older entries were considered first and then it would skip newer entries. This may however run into trouble if the feed contains more items than what's persisted in pubsub.

summary: Subscribe to Atom and RSS feeds over pubsub
---

# Introduction

This module allows Prosody to fetch Atom and RSS feeds for you, and push
new results to subscribers over XMPP.

# Configuration

This module needs to be be loaded together with
[mod\_pubsub][doc:modules:mod\_pubsub].

For example, this is how you could add it to an existing pubsub
component:

``` lua
Component "pubsub.example.com" "pubsub"
modules_enabled = { "pubsub_feeds" }

feeds = {
  -- The part before = is used as PubSub node
  planet_jabber = "http://planet.jabber.org/atom.xml";
  prosody_blog = "http://blog.prosody.im/feed/atom.xml";
}
```

This example creates two nodes, 'planet\_jabber' and 'prosody\_blog'
that clients can subscribe to using
[XEP-0060](http://xmpp.org/extensions/xep-0060.html). Results are in
[ATOM 1.0 format](http://atomenabled.org/) for easy consumption.

# PubSubHubbub

This module also implements a
[PubSubHubbub](http://pubsubhubbub.googlecode.com/svn/trunk/pubsubhubbub-core-0.3.html)
subscriber. This allows feeds that have an associated "hub" to push
updates when they are published.

Not all feeds support this.

It needs to expose a HTTP callback endpoint to work.

# Option summary
