Open Graph

The Open Graph protocol can be used to identify meta data on a website. This is commonly used on social media sites and messaging applications such as slack to show rich embedded objects from url links. To read more about Open Graph see here: opg.me.

Common meta data are things such as title, type, image and url.

Installation

npm install --save open-graph-collector

Usage

var openGraph = require('open-graph-collector');

openGraph('http://www.neogaf.com/forum/', (meta) => {
  console.log(meta);
});

The function takes a url and a callback.

The callback returns a meta data javascript literal object in its first parameter. If an error occured or no meta data was found, meta will be an empty javascript literal object.

Response

A typical and basic response will look like this:

{
  site_name: 'NeoGAF',
  type: 'website',
  image: 'http://www.neogaf.com/forum/images/neogaf2/icon_social.png',
  title: 'NeoGAF',
  url: 'http://www.neogaf.com/'
}

However, object could also be embedded, depending on how much information the html offers. An embedded object may look like:

{
  site_name: 'NeoGAF',
  type: 'website',
  image: {
    url: 'http://www.neogaf.com/forum/images/neogaf2/icon_social.png',
    width: '300',
    height: '300',
  },
  title: 'NeoGAF',
  url: 'http://www.neogaf.com/',
}
