react-native-qr-image-scanner

A React Native module to scan QR codes and barcodes from images on iOS (Swift, Vision framework).

Installation

npm install react-native-qr-image-scanner react-native-nitro-modules

react-native-nitro-modules is required as this library relies on Nitro Modules.

Usage

Scan barcodes/QR codes from an image (iOS only):

import { scanFromPath } from 'react-native-qr-image-scanner';

// You can use any method to obtain an image URI or file path (camera, gallery, file system, etc.)
const scanImage = async (uri) => {
  if (!uri) return;
  const codes = await scanFromPath(uri);
  // codes is an array of { payload, symbology }
  console.log(codes);
};

Note: This module does not require or depend on any specific image picker. You are free to use any method to obtain the image path/URI.

API

• scanFromPath(path: string): Promise<{ payload: string; symbology: string }[]>
  • Scans the image at the given path/URI for barcodes and QR codes.
  • Returns an array of results with the decoded payload and symbology type.
