node-ogp

Easy way to access OpenGraph meta tags from jsdom parsed web page

Installation

Via npm:

$ npm install ogp

As a submodule of your project

$ git submodule add http://github.com/SpeCT/node-ogp.git ogp
$ git submodule update --init

Usage

// 1. load node-ogp
var ogp = require('ogp')

// 2. parse DOM using jsdom
var jsdom = require('jsdom'),
    url = 'http://www.imdb.com/title/tt0068646/'

jsdom.env({ html: url, done: function(error, window) {

    // 3. pass window as the only argument to ogp.parse method
    var ogData = ogp.parse(window)

    // 5. Profit!
    console.log('Open Graph data', ogData)
}})

This will put next structure into stdout:

{ url: 'http://www.imdb.com/title/tt0068646/',
  title: 'The Godfather (1972)',
  type: 'video.movie',
  image: 'http://ia.media-imdb.com/images/M/MV5BMTIyMTIxNjI5NF5BMl5BanBnXkFtZTcwNzQzNDM5MQ@@._V1._SX97_SY140_.jpg',
  site_name: 'IMDb' }

In case if some of OpenGraph tags were presented multiple times (few image tags for example, output structure field related to that tag will be converted into array:

{ image: ['image1.png', 'image2.png']}
