Web Share API

[BearCooder]

Description

The Web Share API is an API for sharing text, links and other content to an arbitrary destination of the user's choice.

While it’s already possible for a user to share content from a webpage via native means, they have to locate the option in the browser menu, and even then, there’s no control over what gets shared. The introduction of this API allows developers to add sharing functionality into apps or websites by taking advantage of the native content sharing capabilities on a user’s device.

Unfortunately the cross browser support is still not great:

• Safari provides full support
• Chrome provides partial support, the share and canShare method is not supported
• Firefox provides no support for share, canshare and other methods

This would be a great oportunity to reach full support on all browsers.

Developer discussions

There is plenty evidence that browser wide support for all methods is needed. People are asking all over again in different mediums why this feature does not work on specific browsers. Some examples:

• Web Share API Doesn't Work on Firefox (React, NextJS)
• How to Use the Web Share API
• Is Web Share API broken on Chrome + Windows 8.1?
• WebShare API Demo - End
• Why does Firefox still not support the Web Share API?
• Does the Web Share API work in Firefox on Android?
• How to share anything from your website by Web Share API

The list can go on and on. Just google web share api and look at stackoverflow etc.
