let data   = 'otpauth://totp/test?secret=B3JX4VCVJDVNXNZ5&issuer=chillerlan.net';

// do stuff
console.log(qrcode);

Client-side, in a webbrowser:

<div id="qrcode-container"></div>
<script type="module">
	import {QRCode} from './dist/js-qrcode-es6-src.js';
	
	// an SVG image as base64 data URI will be returned by default
	let qrcode = (new QRCode()).render('https://www.youtube.com/watch?v=dQw4w9WgXcQ');

	// append it to the DOM
	let img = document.createElement('img');
	img.alt = 'QRCode';
	img.src = qrcode
	
	document.getElementById('qrcode-container').appendChild(img);
</script>
