Accessing QR Code Scan feature on iOS(introduced in Chrome 56) through JS API

[Vibhu Singhal]

Scanning the QR code directly through Chrome is a very powerful feature and I love it. Users can now scan the codes directly through the browser app without needing another app.

However, there are requirements (I have one) where a web app wants to scan the QR code from inside the browser. I'm not sure if there is an API exposed to achieve the same through JavaScript. If it is there, could someone please point me to the resource docs. If not, it would be great if it is introduced.

FYI, this standard is not available on iOS.  The QR code scanner is a feature of the client and there isn't currently a way to activate it through a JS API.

No browser has shipped the shape detection API at the moment, as far as I know.

However, specifically for QR code, there is a JavaScript based parser -

(I have not tried it)
