react-native-nitro-zxing

Barcode scanning for VisionCamera v5, powered by zxing-cpp and implemented as pure C++ Nitro HybridObjects. The camera's luminance plane is decoded in place - no ML Kit, no base64, no temp files.

npm install react-native-nitro-zxing react-native-vision-camera react-native-nitro-modules react-native-nitro-image

import { useFrameOutput } from 'react-native-vision-camera'
import { useBarcodeScanner } from 'react-native-nitro-zxing'

const scanner = useBarcodeScanner({ barcodeFormats: ['all-formats'] })
const frameOutput = useFrameOutput({
  pixelFormat: 'yuv',
  onFrame(frame) {
    'worklet'
    const barcodes = scanner.scanCodes(frame)
    frame.dispose()
  },
})

The API is similar to react-native-vision-camera-barcode-scanner .
