Shareon logo — the Postal Horn emoji

Lightweight, stylish, and ethical share buttons

  • Small. Dependency-free. CSS+JS bundle is only 6 KB minified and brotlied.
  • Stylish. Uses official vector logos and colours with no visual mess.
  • Ethical. Embeds no tracking code. JS is required only for the setup.

See the live demo at shareon.js.org


Simply load the needed files from the CDN:

  • defer makes sure Shareon is loaded after HTML is parsed
  • init will automatically initialize Shareon buttons

Do not auto-initialize

Remove the init attribute and initialize Shareon when you need it:


  // do something

Use ESM build

There is also a ESM build for the browsers, which doesn't support auto-initialization:

<script type="module">
  import { init } from "https://cdn.jsdelivr.net/npm/shareon@2/dist/shareon.es.js";
  // do something

Bundle with Node

You can also install Shareon using your favourite package manager and include it in your source files:

pnpm add shareon  # or `npm install`, or `yarn add`
import { init } from "shareon";
import "shareon/css"; // most bundlers will transpile this CSS


CommonJS imports are also supported:

const Shareon = require("shareon");
require("shareon/css"); // most bundlers will transpile this CSS



Create a container with class shareon and populate it with elements, class names of which match the names of the social networks (or copy-url, for the 'Copy URL' button, or print for the 'Print' button):

<div class="shareon">
  <a class="facebook"></a>
  <a class="fediverse"></a>
  <a class="linkedin"></a>
  <a class="mastodon"></a>
  <!-- FB App ID is required for the Messenger button to function -->
  <a class="messenger" data-fb-app-id="0123456789012345"></a>
  <a class="odnoklassniki"></a>
  <a class="pinterest"></a>
  <a class="pocket"></a>
  <a class="reddit"></a>
  <a class="teams"></a>
  <a class="telegram"></a>
  <a class="tumblr"></a>
  <a class="twitter"></a>
  <a class="viber"></a>
  <a class="vkontakte"></a>
  <a class="whatsapp"></a>
  <a class="copy-url"></a>
  <a class="email"></a>
  <a class="print"></a>

Shareon will populate these <a> elements with correct href attributes.

Use with <button>s

You can use <button> (or any other element) instead of <a>s. In this case, Shareon will create an onclick-listener for each button. I do not recommend doing this, as this is not so good for semantics.

Share metadata

By default, the URL and the title of the active page will be shared. You can customize it with data- attributes. These can be applied on a specific button or on the whole .shareon container:

<div class="shareon" data-url="https://custom.url/for-this-page">
  <a class="facebook" data-title="Custom Facebook title"></a>
  <a class="twitter" data-title="Custom Twitter title"></a>

Apart from the URL and title, some networks support extra parameters:

  • you MUST add data-fb-app-id to the FB Messenger button to make sharing even possible
  • add data-s2f-instance to the Fediverse button to set your Share₂Fedi instance
  • add data-media to an Odnoklassniki, Pinterest, or VK button to customize the pinned picture
  • add data-text to a Mastodon, Telegram, Tumblr, Viber, or WhatsApp button to add custom message text
  • add data-via to a Mastodon, Tumblr, or Twitter button to mention a user
  • add data-hashtags to a Facebook, Tumblr, or Twitter button to include hashtags in the shared post.
    • should be a comma-separated string, for example stuff,tech,buttons
    • Twitter & Tumblr support multiple hashtags
    • Facebook only supports a single hashtag; only the first one will be used

Here are all custom parameters:

<div class="shareon" data-url="https://custom.url/for-this-page">
  <a class="facebook" data-title="Custom Facebook title" data-hashtags="awesome"></a>
  <a class="fediverse" data-s2f-instance="s2f.mydomain.example"></a>
  <a class="messenger" data-fb-app-id="0123456789012345"></a>
  <a class="pinterest" data-media="https://custom.picture/for-pinterest">Pin</a>
  <a class="telegram" data-text="Check this out!"></a>
  <a class="tumblr" data-hashtags="nice,buttons" data-text="These are some nice buttons" data-via="myblog"></a>
  <a class="twitter" data-via="MyNickname" data-hashtags="shareon,awesome,brilliant"></a>
  <a class="mastodon" data-via="@MyNickname@myserver.social"></a>
  <a class="whatsapp" data-url="https://custom.url/for-whatsapp">Send</a>
