Shariff enables website users to share their favorite content without compromising their privacy.
Facebook, Google+ and Twitter supply official sharing code snippets which quietly siphon personal data from all page visitors. Shariff enables visitors to see how popular your page is on Facebook and share your content with others without needless data leaks.
Shariff (/ˈʃɛɹɪf/) is an open-source, low-maintenance, high-privacy solution maintained by German computer magazine c't and heise online.
Shariff consists of two parts: a simple JavaScript client library and an optional server-side component. The latter fetches the number of likes, tweets and plus-ones. Share buttons and share counts work without a connection between your visitors' browsers and social networks (unless they decide to share, of course).

$ npm install shariff --saveEdit your JS main script, include Shariff and initialize it in one or more containers:
// my-app.js
var Shariff = require('shariff');
var $ = require('jquery');
var buttonsContainer = $('.some-selector');
new Shariff(buttonsContainer, {
orientation: 'vertical'
});After downloading Shariff, install its dependencies by running npm install.
$ git clone https://github.com/heiseonline/shariff.git
$ cd shariff
$ npm install

In order to display share counts with Shariff, you need one of the following backends:
Third-party backends:
Once you have one of these backends up and running, insert its URL into the data-backend-url attribute. For example, if the backend runs under http://example.com/my-shariff-backend/, the data-backend-url should be /my-shariff-backend/. The script will handle the rest.
