Shariff – Give Social Media Buttons Some Privacy

Shariff enables website users to share their favorite content without compromising their privacy. Demo

Some social service providers like e.g. Facebook 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 or shares. Share buttons and share counts work without a connection between your visitors' browsers and social networks (unless they decide to share, of course).

Getting Started

Download the latest release
Upload all files included in the release
Include CSS in <head>:
- shariff.complete.css uses the dependencies included in the release files
- if Font Awesome is already included in your site, use build/shariff.min.css
Include JavaScript right before </body>:
- shariff.complete.js uses the dependencies included in the release files
- if jQuery is already included in your site, use build/shariff.min.js
Insert one or more <div class="shariff"> elements.
Customize the look using data-* attributes.

To enable the counters in the buttons, see section Backends.

Usage example:

<!DOCTYPE html>
<html>
<head>
    <link href="/path/to/shariff.min.css" rel="stylesheet">
</head>
<body>
    <h1>My article</h1>
    <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p>

    <h2>Minimum buttons:</h2>
    <div class="shariff"></div>

    <h2>More advanced buttons:</h2>
    <div class="shariff" data-backend-url="/path/to/backend" data-url="http://www.example.com/my-article.html" data-theme="grey" data-orientation="vertical"></div>

    <!-- immediately before </body> -->
    <script src="/path/to/shariff.min.js"></script>
</body>
</html>

Getting Started using `npm`

You can also use Shariff's node package by installing it via npm:

$ cd my-project
$ npm install shariff --save

Edit 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'
});

Running demo site

After downloading Shariff, install its dependencies by running npm install.

$ git clone https://github.com/heiseonline/shariff.git
$ cd shariff
$ npm install
$ npm run dev

Constructor arguments

All data attributes above are also available as constructor arguments in JavaScript. However, the leading data- is omitted and the name is in camelCase instead of kebab-case:

var buttonsContainer = $('.some-selector');
new Shariff(buttonsContainer, {
    backendUrl: '/my/backend/url',
    orientation: 'vertical',
    mailUrl: 'mailto:[email protected]',
});

Events

Shariff buttons emit the shariff-share event if they are clicked.

$('body').on('shariff-share', function(event) {
    var service = event.details;
    ...
});

This can be used to track shares using analytics software. It is recommended to register the event handler only after the analytics script becomes available.

Piwik example:

(function() {
  var _my_piwik_onload = function() {
    var piwik = this;

    $('body').on('shariff-share', function(event) {
      var service = event.detail;
      piwik.trackEvent('Sharing', service.name);
    });
  }

  _paq.push([ _my_piwik_onload ]);
})();

Backends

In order to display share counts with Shariff, you need the following backend:

shariff-backend-php

Third-party backends:

shariff-backend-java

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.
