This is an npm module for qrcode JavaScript library (http://www.d-project.com/qrcode)
Notice that I am not the author of the code, I am just the creator of an npm module out of the great library from Kazuhiko Arase Notice also that there is another module (node-qrcode, see: https://github.com/soldair/node-qrcode), which is more sophisticated, but that uses canvas module. If your target system can run the canvas module then I recommend using node-qrcode, otherwise use qrcode-npm
var qrCode = require('qrcode-npm')
var qr = qrCode.qrcode(4, 'M');
qr.addData(text);
qr.make();
qr.createImgTag(4); // creates an <img> tag as text
qr.createTableTag(4); // creates a <table> tag as text
npm install qrcode-npm
