OpenGraphJS

OpenGraphJS builds a JSON object from a web page which follows the Open Graph Protocol. The JavaScript object returned by this library contains important metadata such as the description, image, and title.

Installation

npm install opengraphjs

Usage

Promise support

• Its easy, if you are using a version of node with Promises you are ready to go!
• Other versions of node:
  • define global.Promise = require('bluebird');
  • Feel free to substitute Bluebird with your perferred promise library

// Include it
var ogjs = require('opengraphjs');
// Pass in a URL
ogjs({ url: 'http://senorcris.com' })
  .then(function (data) {
    console.log(data); // some share data parsed from metatags..
  }, function (err) {
    console.log('It seems that we have fumbled with an error', err);
  });
