React Native DataWedge

A React Native module for integrating with Zebra DataWedge on Android devices.

Installation

npm install react-native-kega-datawedge
# or
yarn add react-native-kega-datawedge

Usage

Basic Barcode Scanning

import { BarcodeModule } from 'react-native-kega-datawedge';

// Start scanning with default decoders
BarcodeModule.read({
  type: ["QR", "Code 128", "Code 39", "EAN-13", "UPC-A", "PDF417"]
});

// Listen for scan results
BarcodeModule.addEventListener('onBarcode', (scanData) => {
  console.log('Scanned:', scanData.data);
  console.log('Type:', scanData.labelTypeName);
});

Advanced Configuration with Custom Parameters

You can pass additional DataWedge parameters using the params array. Each parameter should be an object with key and value properties:

BarcodeModule.read({
  type: ["QR", "Code 128"],
  params: [
    { key: "picklist_enabled", value: "true" },
    { key: "decode_led_feedback", value: "false" },
    { key: "decode_audio_feedback_uri", value: "system_default_notification" },
    { key: "decode_haptic_feedback", value: "true" },
    { key: "illumination_mode", value: "off" }
  ]
