Barcode detection in a Web Worker using Comlink
In this post, I share how I used Comlink to simplify the worker logic in my QRSnapper project, which aims to achieve 60fps UI and near-instant QR code detection using getUserMedia. The code now utilizes the Barcode Detection API within a Web Worker for efficient QR code scanning. If the native API is available, the code uses it; otherwise, it falls back to a polyfill. This approach keeps the UI responsive while offloading the processing to a separate thread, significantly improving performance.
