Web Share Target now allows targets to specify that they accept files.

A POST request to a pre-defined endpoint is not sufficient in my opinion, as it would exclude all client-side apps (a.k.a. PWAs) from being a share target. Or maybe I understand this wrong?

PWAs can still be share targets and handle shares client-side. I implemented a demo, see the service worker's fetch handling code.

Ignoring control flow complications from promises, we essentially have

const formData = await event.request.formData();
const files = formData.getAll(...);  // sequence of File objects
...
  const fileReader = new FileReader();
  fileReader.onload = ...;
  fileReader.readAsText(..., 'UTF-8');

Ah, I didn't know SW could handle posted form data. Thanks!
