share-menu v5.1.0

\<share-menu>

Demo and API docs

A complete and simple to use share menu that uses Web Share API when possible, with a fallback to a nice share menu that tries to emulate the experience of the native one.

Features

• Incredibly simple to use. Just set one of the title, text, url, or image properties and call the share() method to make the magic happen;
• Highly customizable. It offers a great material design UI by default, but it is also designed to be as much customizable as possible through CSS custom properties and shadow parts. It also offers lots of built-in share targets and presets, with support for custom ones if needed;
• Compatible with any major browser. The Web Share API is still quite young, but the fallback dialog works on any browser supporting Custom Elements (directly or through a polyfill). Unlike the native share menu, the fallback will also work on desktop browsers and insecure contexts, so you will be able to offer a much more coherent experience to your users;
• Lightweight. The share-menu element itself weighs ~11.7 KB (~3.7 KB when compressed), while each built-in share target weighs on average ~700B (less than half the size when compressed);
• Thoroughly tested. Both the native and fallback behaviors are covered by tests, including each share target and preset. Minimum code coverage is set to 90% to ensure that each new feature maintains a high level of quality.

Installation

npm i share-menu
# or
yarn add share-menu
# or
bun i share-menu

Without npm/yarn/bun

If you just want to directly include the script without installing it as a dependency, use the jsDelivr ESM CDN (esm.run):

<!-- Main component -->
<script type="module" src="https://esm.run/share-menu@5.1.0"></script>
<!-- Single share target -->
<script
  type="module"
  src="https://esm.run/share-menu@5.1.0/targets/email.js"
></script>
<!-- Share target preset -->
<script
  type="module"
  src="https://esm.run/share-menu@5.1.0/targets/presets/all.js"
></script>

Try it now!

Try copy-pasting this code on your browser's console in any website:

var a = document.createElement('script');
a.type = 'module';
a.textContent =
  'import"https://esm.run/share-menu@5.1.0";import"https://esm.run/share-menu@5.1.0/targets/presets/all.js";var b=document.createElement("share-menu"),c=document.createElement("share-target-preset-all");b.appendChild(c),document.body.appendChild(b),b.share();';
document.head.appendChild(a);

Note: these scripts will not work if the website implements a strict CSP (Content Security Policy). For example, these scripts won't work on GitHub.

Defining the share targets (for the fallback dialog)

Built-in targets

This component comes with a large number of built-in targets that can be used to share content to the most popular social networks and messaging apps. These targets can be found in the targets folder and can be imported as follows:

import 'share-menu/targets/<target>.js';

Here you can see the list of the built-in targets, as well as the capabilities and limitations of each of them:

Presets

Given the large number of built-in targets, it can be quite tedious to add them all to the share menu. For this reason, this component offers a few presets that can be used to add a collection of targets at once. Presets can be found in the targets/presets folder and can be imported as follows:

import 'share-menu/targets/presets/<preset>.js';

Here is the list of the available presets, together with the targets included in each of them:

Custom share targets

Share targets in the fallback dialog are just simple HTML custom elements that implement the ShareTarget interface. More specifically, they must expose:

• A displayName field that contains the name of the target;
• A color field that contains the hex color of the target without the hash;
• An icon field that contains the SVG path of the icon of the target; Only the path must be provided (i.e. what you have inside the the d attribute of your SVG), not the whole SVG. Icon must will be rendered inside a 256x256 viewBox, so make sure that the icon fits correctly inside that area;
• A share method that takes the ShareMenu instance as parameter and that performs the actual share action when the target button is clicked;
• Optionally, an outline field that contains the hex color of the outline of the target without the hash;
• Optionally, a hint field that contains an additional hint text for the target.

See any of the built-in targets for a practical example on how to implement yours.

Styling

The following custom properties and shadow parts are available for styling:

Note: for obvious reasons, these custom properties and shadow parts are not available when using the native share menu.
