ostatus-js: an attempt to implement OStatus in JavaScript:

OStatus consists of the following protocols:

• PubSubHubbub
• Atom
• RSS
• Salmon
• ActivityStreams
• WebFinger

How much is done?

• There are Mustache XML templates for OStatus protocols inside of the templates folder. See CouchAppSpora for an example of how to render these Mustache templates in CouchDB.

• ATOM and XRD parsers from banksean’s node-webfinger

• RSS/ATOM to ActivityStreams JSON (xmlToActivityStream.js) is useful for converting feeds on the fly

The rest of the OStatus protocols still need to be implemented (pending). If you have feedback or ideas please use the Wiki

An example!

WebFinger requires that your server respond to a certain URL with a certain XML blob called an XRD, so if you curl http://gmail.com/.well-known/host-meta you will receive:

  <?xml version='1.0' encoding='UTF-8'?>
  <XRD xmlns='http://docs.oasis-open.org/ns/xri/xrd-1.0' 
       xmlns:hm='http://host-meta.net/xrd/1.0'>
    <hm:Host xmlns='http://host-meta.net/xrd/1.0'>gmail.com</hm:Host>
    <Link rel='lrdd' 
          template='http://www.google.com/s2/webfinger/?q={uri}'>
      <Title>Resource Descriptor</Title>
    </Link>
  </XRD>

You can use the xrd.xml.mu template and Mustache.js to generate a nice blob of XML just like the above example!

Ideally this will support the XML heavy OStatus as well as JSON alternatives to the individual OStatus XML protocols, such as JRD, the JSON version of XRD.

Why?

CommonJS compatible JavaScript servers like CouchDB would be awesome if they could talk OStatus!

These protocols are being built in order to power another project of mine, couchappspora.
