sharon

A lightweight and modular social sharing library:

• a toolkit to build your own share buttons;
• supports 12 sharing platforms;
• gzipped size is 1.52 KB;
• you can cherry-pick which sharing platforms to use to make it even smaller.

Here how it looks when you want Sharon to open a tweet popup:

sharon.twitter({
  title: 'One last quarter as defending champs!',
  hashtags: ['SuperBowl', 'DenverBroncos']
});

Or to get a Facebook share count for your page:

sharon.facebook.count(function (err, count) {
  if (err) throw err;
  console.log('Whoa, we have ' + count + ' shares!');
});

This table also shows which of the platforms support retrieving share counts and links to the share parameters references.

sharon.platform(url = location.href, parameters = { title: document.title })

• url <String> The URL to share. Defaults to the current location.
• parameters <Object> Share parameters. Default to an object with the title property equal to the current page title.

Opens a share popup.

Examples

Share the current page:

sharon.twitter();

With a custom title:

sharon.twitter({title: 'Check it out'});

Share example.com:

sharon.twitter('http://example.com');

Share example.com with a custom title:

sharon.twitter('http://example.com', {title: 'Check it out'});

sharon.platform.href(url = location.href, parameters = { title: document.title })

• url <String> The URL to share. Defaults to the current location.
• parameters <Object> Share parameters. Default to an object with the title property equal to the current page title.
• Returns: <String>

Returns a share popup URL.

Examples

Get the share popup URL for the current page:

var link = sharon.twitter.href();

With a custom title:

var link = sharon.twitter.href({title: 'Check it out'});

For example.com:

var link = sharon.twitter.href('http://example.com');

For example.com with a custom title:

var link = sharon.twitter.href('http://example.com', {title: 'Check it out'});

sharon.platform.count(url = location.href, callback)

• url <String> The URL of which to retrive the share count. Defaults to the current location.
• callback <Function(err, count)> A callback function that receives the count.

Retrieves the share count of a URL.

Examples

Share count for the current page:

sharon.facebook.count(function (err, count) {
  if (err) throw err;
  console.log(count);
});

For example.com:

sharon.facebook.count('http://example.com', function (err, count) {
  if (err) throw err;
  console.log(count);
});

Share parameters

When using sharon.platform or sharon.platform.href functions you can specify the share parameters by passing an object as the last argument. They are added to the query parameters of the share popup URL and are specifying additional features:

sharon.twitter({
  title: 'One last quarter as defending champs!',
  hashtags: ['SuperBowl', 'DenverBroncos']
});

This produces a popup with a predefined title and hashtags:

The set of the features is different for the most of the sharing platforms. To find them out check their documentation, links to which are provided in the Supported sharing platforms table.

There is an inconsistency between different platforms: for instance, Twitter expects the text parameter to contain a link title, while Pinterest expects the description one. Sharon normalizes this behavior: when you pass a title parameter it's automatically translated into a one that corresponds to a chosen platform.

Poor man's tweet button

<button type="button" onclick="sharon.twitter()">Tweet</button>

Angular

<a ng-click="share($event)" ng-href="{{href}}">Share on Facebook {{count}}</a>

$scope.href = sharon.facebook.href();

$scope.share = function (event) {
  event.preventDefault();
  sharon.facebook();
};

sharon.facebook.count(function (err, count) {
  if (err) throw err;

  $scope.$apply(function () {
    $scope.count = count;
  });
});

React component

class LinkedInShareButton extends React.Component {
  constructor(props) {
    super(props);
    this.state = {href: sharon.linkedin.href()};

    sharon.linkedin.count((err, count) => {
      if (err) throw err;
      this.setState({count});
    });
  }

  share(event) {
    event.preventDefault();
    sharon.linkedin();
  }

  render() {
    return <a onClick={this.share} href={this.state.href}>Share on LinkedIn {this.state.count}</a>;
  }
}
