A javascript port of chillerlan/php-qrcode, a QR Code library based on the implementation by Kazuhiko Arase.
An API documentation created with jsdoc can be found at https://chillerlan.github.io/js-qrcode/ (WIP).
Server-side, in nodejs:
import {QRCode} from './dist/js-qrcode-node-src.cjs';
let data = 'otpauth://totp/test?secret=B3JX4VCVJDVNXNZ5&issuer=chillerlan.net';
let qrcode = (new QRCode()).render(data);
// 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>
Have a look in the examples folder for some more usage examples.
