Overview

Provides the ability to share a URL provided by the product
Uses a standard set of social media icons.

Usage

Check out how to include Origami components in your project to get started with o-share.

Markup

The following markup is the simplest but requires JavaScript to work and does not support custom share icons or icon labels. If your project requires either of those features see the full markup section.

<div data-o-component="o-share"
    class="o-share"
    data-o-share-links="{{links}}"
    data-o-share-url="{{url}}"
    data-o-share-title="{{title}}"
    data-o-share-titleExtra="{{titleExtra}}"
    data-o-share-summary="{{summary}}"
    data-o-share-relatedTwitterAccounts="{{relatedTwitterAccounts}}"
    data-o-share-location="{{locationOfShareComponent}}">
</div>

links: List of lower case social networks to be added separated by a space.
url (optional): The URL to be shared. Defaults to the current url.
title (optional): The title of the content to be shared
titleExtra (optional): Any additional text relating to the title, e.g. site section.
summary (optional): Summary text to be shared.
relatedTwitterAccounts (optional): Comma-separated list of Twitter accounts to encourage the user to follow. See Twitter intents for more info.
locationOfShareComponent (optional): A unique identifier for the share component which is used to track shares when multiple components exist on the page.

The different social networks are (in the order suggested by the design team):

Twitter
Facebook (note: Facebook doesn't accept meta data attributes in the same way as the other sharing services, instead the Facebook Crawler uses internal heuristics to make a best guess about the title, description, and preview image for your content. You can provide specifics for these attributes to facebook by using Open Graph meta tags)
Linkedin
Whatsapp (note: this link does nothing if Whatsapp is not installed)
Pinterest

Small

Add the o-share--small class for smaller icons. This is useful when including multiple instances of o-share to share items within a page, rather than to share the current page itself.

-<div data-o-component="o-share" class="o-share">
+<div data-o-component="o-share" class="o-share o-share--small">
    <!-- more o-share markup -->
</div>

Full Markup

Include the complete markup, available in the Origami registry directly to:

Support a core experience, where JavaScript is unavailable or has failed.
Add custom share actions with text labels.

<!-- see the registry demos for full markup -->
<div data-o-component="o-share" class="o-share">
    <ul>
        <!-- a share to twitter action example -->
        <!-- href tag is not shown, see the registry demos for full markup  -->
        <li class="o-share__action">
            <a class="o-share__icon o-share__icon--twitter"
                href="#twitter-link-here"
                rel="noopener">
                <span class="o-share__text">Twitter</span>
            </a>
        </li>
        <!-- more o-share actions -->
    </ul>
</div>

Open In A New Tab

Social share actions open in the same frame, but you may add target="_blank" to the <a> element if your project requires share links are opened in a new tab/window where supported.

Text Labels

Add the o-share__action--labelled class to any share action to display the action text alongside the icon. This example uses the twitter action, but we recommend this only for custom actions which are less recognisable compared with big social media brands.

<!-- see the registry demos for a full markup example -->
<div data-o-component="o-share" class="o-share">
    <ul>
-		<li class="o-share__action">
+		<li class="o-share__action o-share__action--labelled">
            <a class="o-share__icon o-share__icon--twitter"
                href="#twitter-link-here"
                rel="noopener">
                <span class="o-share__text">Twitter</span>
            </a>
        </li>
        <!-- more o-share actions -->
    </ul>
</div>

Custom Actions

Form markup is allowed within the o-share__action label to to handle custom share actions.

<!-- see the registry demos for full markup -->
<div data-o-component="o-share" class="o-share">
    <ul>
        <!-- a custom share action example which includes a text label -->
        <li class="o-share__action o-share__action--labelled">
            <!-- form markup is allowed to handle custom share actions -->
            <form method="post" action="#">
                <button type="submit" class="o-share__icon o-share__icon--share">
                    <span class="o-share__text">Save</span>
                </button>
            </form>
        </li>
        <!-- more o-share actions -->
    </ul>
</div>

The share icon is made available by default for custom share features as shown in the Origami registry demos.

Sass

@import '@financial-times/o-share/main';

The oShare mixin is used to output the o-share styles.

@include oShare();

We recommend passing the oShare mixin an optional argument $opts, to specify styles granularly and keep your CSS bundle small.

For example:

@include oShare($opts: (
    'sizes': ('small'), // output styles for a small variation of o-share i.e. o-share--small
    'vertical': true, // output styles for a vertical o-share i.e. o-share--vertical
    'icons': ('twitter', 'facebook', 'whatsapp') // output styles for select share icons
));

All $opts options include:

icons (list) a list of social share icons to output. One or more of the following, or any o-icon name:
- twitter
- facebook
- linkedin
- link
- share
- mail
- pinterest
- whatsapp
sizes (list, optional) output styles for different size variants of o-share
- small - a variant to make o-share smaller than default, i.e. o-share--small
vertical (boolean) - Whether to output styles for the vertical variant, i.e o-share--vertical
inverse (boolean) - Whether to output the inverse theme for dark backgrounds, i.e o-share--inverse

Colour Usecases

o-share sets custom colour usecases for matching the colour of share buttons. These usecases are limited, for example they do not provide colours for the inverse variant, and not recommended for new projects (it is possible to output custom icons using the oShare mixin, without matching colours).

Usecase	Property	Uses
`o-share/default-icon`	background, border, text	Default colours, used by icons without a state (e.g. before hover).
`o-share/ft-icon`	background, border, text	Colours to highlight FT icon social buttons like email (e.g. on hover).
`o-share/[social-icon-name]-icon`	background, border, text	Colours to highlight social buttons with a brand, like Twitter (e.g. `o-share/twitter-icon` on hover).

Use the oColorsByUsecase mixin from o-colors to retrieve custom colour usecases set by o-share.

.my-icon:hover {
    background-color: oColorsByUsecase('o-share/ft-icon', 'background');
}

JavaScript

To instantiate the JavaScript:

import oShare from '@financial-times/o-share';
var oShareInstance = new oShare(document.querySelector('[data-o-component=o-share]'));

The markup will be generated for that instance of o-share.

You can also instantiate all instances in your page by running oShare.init which returns an array with all of them.

Alternatively, an o.DOMContentLoaded event can be dispatched on the document to run #init():

document.addEventListener("DOMContentLoaded", function() {
    document.dispatchEvent(new CustomEvent('o.DOMContentLoaded'));
});

Check out the API docs

Events

The following events are fired by o-share.

oShare.ready
oShare.open

oShare.ready

oShare.ready fires when a o-share instance has been initialised.

The event provides the following properties:

detail.share - The initialised o-share instance.

oShare.open

oShare.open fires when a social network share action is triggered, to open a new window.
