A lightweight JavaScript/TypeScript QR code scanner library based on Cosmo Wolfe's port of Google's ZXing library. It supports webcam video stream and single-image scanning, runs in a WebWorker, and uses the browser's native BarcodeDetector when available.
Use cases
- scan QR codes from the webcam in a web app
- decode QR codes from uploaded images in the browser
- add QR code login to a website
- read QR codes without freezing the UI thread
- scan colored or inverted QR codes in JavaScript
When to choose
- you need a small, fast, browser-based QR scanner with high detection accuracy
- you want webcam and image scanning out of the box
- you need the main thread to stay responsive during scanning
When to avoid
- you need to scan barcode formats other than QR codes
- you need QR scanning in a native mobile app rather than the browser
- your target browsers lack WebWorker or camera API support
