Barcode detection in a Web Worker using Comlink
I'm a big fan of QRCodes, they are very simple and neat way to exchange data between the real world and the digital world. For a few years now I've had a little side project called QRSnapper — well it's had a few names, but this is the one I've settled on — that uses the getUserMedia API to take live data from the user's camera so that it can scan for QR Codes in near real time.
