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>
