In this library, several improvements have been applied over the original port:
Web cam scanning support out of the box
Uses the browser's native BarcodeDetector if available
Lightweight: ~59.3 kB (~16.3 kB gzipped) minified with Google's closure compiler. If the native BarcodeDetector is available, only ~15.3 kB (~5.6 kB gzipped) are loaded.
Improved performance and reduced memory footprint.
Runs in a WebWorker which keeps the main / UI thread responsive.
Can be configured for better performance on colored QR codes.
The library supports scanning a continuous video stream from a web cam as well as scanning of single images.
The development of this library is sponsored by nimiq, world's first browser based blockchain.
