Hello.

Mobile devices lack the bookmarklet functionality found in desktop browsers. However, the ShareTarget API offers a potential workaround. This API allows web apps to be installed and receive native share actions, similar to how the Twitter PWA handles shared links and files. By leveraging this API, developers can create mini-apps that perform actions on shared data. This approach involves defining how to receive data in a manifest file and handling the request in a service worker. I've created examples for Hacker News, Reddit, and LinkedIn demonstrating how to utilize the ShareTarget API. While not a perfect replacement for desktop bookmarklets, this offers a new level of hackability for mobile web experiences.
