BeagleJS Build Status

Release a Beagle dog to scrape a web site for you.

The intention of this library is to get the relevant information of a site like title, image and description.

How it works?

Scraping the meta-data and falling-back in this order:

  1. Facebook OpenGraph

    og:title
    og:image
    og:description

  2. Metas

    meta[name]
    meta[image_src]
    meta[description]

  3. Looking into DOM (needs to be improved)

    title tag
    img tags
    some p or div

How to use it?

npm install beagle

    }

    beagle.scrape(response, function(err, bone){
