react-native-qrcode-svg

@amazon-devices/@amazon-devices/react-native-qrcode-svg provides support on Vega for react-native-qrcode-svg which is a QR Code generator based on react-native-svg and javascript-qrcode.

This is a system-deployed library and is available to React Native for Vega apps without a separate installation process. It is deployed as an autolinking library which your app links to at runtime. Compatibility is guaranteed only between the library and the version of React Native for Vega for which it is built.

When you up level the version of React Native for Vega with which your app is built, it a best practice to also uplevel the version of the library on which it is dependent.

For more information about this library and its API, see the README.md in the Official GitHub repo.

Installation

1. Add the JavaScript library dependency in the package.json file:

   Copy code Copied to clipboard.

   "dependencies": {
      ...
      "@amazon-devices/react-native-qrcode-svg": "~2.0.0"
   }
   

2. Due to a known issue with React Native dependencies, you must apply the following workaround:
   1. Open your .npmrc file in the same directory as your app's package.json file. (If the .npmrc does not exist, add one).
   2. Add the following line:

      Copy code Copied to clipboard.

      legacy-peer-deps=true
      

3. Reinstall the dependencies using npm install command.

Examples

The following is a example of creating a QRcode using the default settings:

Copy code Copied to clipboard.

import QRCode from '@amazon-devices/react-native-qrcode-svg';

// Simple usage, defaults for all but the value
render() {
  return (
    <QRCode
      value="http://awesome.link.qr"
    />
  );
};

The following is a example of creating a QR code and applying some formatting:

Copy code Copied to clipboard.

import QRCode from '@amazon-devices/react-native-qrcode-svg';

render() {
    return (
        <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center',backgroundColor: 'white'}}>
            <QRCode value="http://amazon.com/code?cbl-code=FTV123&client=FireTvQR" ecl="L" size={300} />
        </View>
    );
};

Implementation details

Known issues

Your app may crash if you use the react-native-qrcode-svg library and try to import the TextEncoder property. To work around this issue, add a dependency on fast-text-encoding to your app.

In your app's package.json file, add the following to the dependencies section:

"dependencies": {
   ...
   "fast-text-encoding": "^1.0.6"
}

In the place where you imported the react-native-qrcode-svg library, import fast-text-encoding.

import React, {useState} from 'react';
import {StyleSheet, Text, ImageBackground, View, Image} from 'react-native';
import QRCode from '@amazon-devices/react-native-qrcode-svg';
import "fast-text-encoding" // Add fast text encoding
