React Simple QR Scanner

A simple React wrapper around browser native BarcodeDetector API.

Compatibility

⚠️ Support is really not good at the moment, but enough for my use case.
If I have the time I may try to use the canvas method to have a fallback when BarcodeDetector is not available.
You can check here the global support of this API: caniuse

npm i @fabiendeborde/react-simple-qr-scanner
