vision-camera-zxing

A barcode reading frame processor plugin for Vision Camera using ZXing.

It uses ZXing Android Embedded for Android and ZXingObjC for iOS.

Installation

npm install vision-camera-zxing
cd ios && pod install

Add the plugin to your babel.config.js:

module.exports = {
   plugins: [['react-native-worklets-core/plugin']],
    // ...

Note: You have to restart metro-bundler for changes in the babel.config.js file to take effect.

Usage

1. Scan barcodes with vision camera.

   import { zxing } from 'vision-camera-zxing';
    
   // ...
   const frameProcessor = useFrameProcessor((frame) => {
     'worklet';
     const barcodes = zxing(frame,{multiple:true});
   }, []);

2. Scan barcodes from a base64-encoded static image.

   let results = await decodeBase64(base64,{multiple:true});

Limitation

ZXing has a requirement of the direction of the barcode to scan and cannot return the exact barcode region.

You can use Dynamsoft Barcode Reader instead to meet your needs.
