A component for React. This library works with React and React Native (using React Native SVG).
npm i react-qr-code
When using this library with React Native, you will also need to have react-native-svg installed.
npm i react-native-svg
cd ios && pod install
import React from "react"; import ReactDOM from "react-dom"; import QRCode from "react-qr-code"; ReactDOM.render(<QRCode value="hey" />, document.getElementById("Container"));
Note: If the QR code is likely to appear next to dark objects, you will need to wrap it in a light-colored container to preserve the 'quiet zone', e.g.
<div style={{ background: 'white', padding: '16px' }}> <QRCode ... /> </div>
Responsive QR code example:
// Can be anything instead of `maxWidth` that limits the width. <div style={{ height: "auto", margin: "0 auto", maxWidth: 64, width: "100%" }}> <QRCode size={256} style={{ height: "auto", maxWidth: "100%", width: "100%" }} value={value} viewBox={`0 0 256 256`} /> </div>
