The Gist

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>
