Web Share API

How use the web's native share-API

The gift of giving

Using the next generation of web apps has some clear advantages, one of which is using the navigator's share-API. Thanks to an ever evolving rich set of capabilities, your navigator of choice is now able to invoke Web Share API to share the following items:

  • plain text
  • links by providing a title
  • files directly

If a user's browser supports the new navigator.share, you can use this feature right now!

Demo time!

Using the share-functionality is as straightforward as it gets, here's an example that's actually used on the site:

  aria-label={"Share this article"}
  onClick={() => {
    // '.share' can only by called when
    // triggered by click-events to make
    // sure it's the user's intention.
      title: info.title,
      text: info.description,
      url: `${getBaseRoute(routes.posts)}/${info.slug.current}`,
    // Optionally virbrate slightly.
     navigator.vibrate?.([30, 20, 10]);
  <ShareIcon />

As you can see, this callback invokes the async share-function (if possible) and provides some data so that a nice URL + descriptive title and subtitle can be shown in the share-sheet. The code shown is used in a slightly different variant at the end of this article. If you browser supports sharing, then a related button will be rendered in the "Actions"-row.

Where to use

As of writing, the API can mostly be used on mobile variants of the popular browsers (Chrome, Opera, Safari) but only on Safari + Edge on Desktop. As this functionality is not limited to specific hardware requirements, I expect support to increase in the coming months.

And yeah, that was a quick intro to the Web Share API, for more information check out the linked web.dev as well as MDN articles in the addendum.
