I would like to use something like this:
https://www.npmjs.com/package/grunt-obfuscator-node
But it needs you to use require which I don't want.
There should be some library that does the same thing without the require?

So I've tried this on my phone and it does nothing, I've moved the same foto's to my desktop and it works there....

It doesn't seem to support the newer versions of QR-Codes,
the library project seems inactive so I might fork it and create a TypeScript project and port it to an npm module.

Why not google? I don't want an API key.

Is this even a possibility?

preferably to hexadecimal properties

I'd like to have a working live camera on all smartphones at least.

Add TS comments everywhere

This includes a terms of agreement at first visist.

It currently points to this github repo but it needs to be:
'https://http://marvin-brouwer.github.io/QR-Reader'
Changing it says it's not whitelisted yet, so I guess I'll have to wait for the crawler a few days.

Add another imageprocessor whom inherits from UploadDataProcessor and allow drag&drop functionality

This is old stuff, and it stopped working a while ago.
I still like the idea of getting a preview before opening the QR contents so I'll keep that.
However, I'd like to go complete PWA and perhaps using something that compiles to WASM to rebuild the QR reading logic so I can learn from it.

Add a button for selecting camera

I want to detect the qr code from a regular photo if that's possible
