What Hacker News says
3 sourcesHey, the BarcodeDetector API has been around for some time, just crucially not on iOS. I didn't know about the polyfills though!
If you're looking to only scan QR codes, https://github.com/nimiq/qr-scanner is a library I can recommend and which I've used in a previous project.
One thing the BarcodeDetector API does not give you is a UI for your barcode scanning. Basically it's your job to acquire an image and pass it to the API. With STRICH, you just provide an HTML element and the scanner will live in there, including controls for camera selection and flashlight (only on Android, unfortunately).
