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).
• url.host.all For all hostnames.

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