Events

This plugin emits the following generic, do what ever you want with it, events.

url.host.HOSTNAME For example url.host.twitter.com (www. is stripped from the hostname).

This plugins also emits two events for url shortening. Only called when there are listeners registered. Each event emit is passed a UrlshorteningEvent, if a shortener resolved short url it calls the resolve method on the promise.

url.shorten.all For all hostnames.

UrlSectionFilter

This plugin comes with the UrlSectionFilter that lets you filter on the different key value pairs coming out of parse_url. The following example filter allows www.phergie.org, www2.phergie.org, and phergie.org:

new OrFilter([
    new UrlSectionFilter('host', '*.phergie.org'),
    new UrlSectionFilter('host', 'phergie.org'),
])

The filter comes with a third strict parameter where instead of declaring out of scope on missing an URL part it return false.
