There is emscripten-qt that built Qt apps w/ Emscripten for a while now[0] (since asm.js and WASM should not change anything even though it hasn't had updates in a few years). Appears this uses Emscripten as well. I wonder how this compares at a tech level.

So, you're saying I could use a QTWebView in the browser?

Yo, I heard you like browsers, so we put a browser in your browser, so you can surf while you surf.

How long until someone uses this to make an Electron app?

This would be for the QtQuick backend.

The QTWebView is a separate plugin component with its own set of dependencies.

You wouldn't want to do that anyways, much more effecient to just communicate from Qt to Javascript webviews (but I'm sure you know that :))

What would be the security model of such a browser environment? Maybe like an iframe?

"Because you can doesn't mean you should." -common sense.

But then again, since 2017, anything that can happen will.

Once we compile Chromium to webassembly, we can run Qt in Chromium in Chromium in Slack!
