Building a Native QR/Barcode Scanner for React Native — New Architecture Ready
A new native QR and barcode scanner for React Native has been developed, addressing common issues with existing libraries. This scanner, named react-native-qr-camera-pro, utilizes native code for improved performance and efficiency. It operates without JavaScript frame processing, ensuring a smoother experience on both iOS and Android platforms.
- ▪The scanner is built entirely with native code, eliminating unnecessary dependencies.
- ▪It uses Apple's AVCaptureMetadataOutput on iOS and Google's CameraX with ML Kit on Android for barcode detection.
- ▪The architecture includes a public API, a native bridge, and native platform logic, ensuring minimal JS involvement in frame processing.

I wanted something lean, production-grade, and built the right way. So I built it.
