Description

Background

I wrote up some background on the emscripten-discuss group here.

To summarise, src/shell.js contains some calls to XMLHttpRequest (XHR). The Fetch API is a replacement for XHR, that has quite widespread support (https://caniuse.com/#search=fetch). Service Worker does not support XHR in Chrome or Firefox (I have not tested other browsers).

Affected files

src/shell.js

Proposed solution

Use Fetch in preference to XHR on supported platforms.

Known/potential problems

Fetch does not support the File URI scheme (ticket). Further analysis is required to understand how this would affect emscripten. XHR might be required as a fallback.
