Build Status Coverage Status

QR code generator, supports Numeric, Alphanumeric and Binary inputMode up to lvl 40.

We use bower for dependency management. Add

dependencies: {
 "qrcode": "latest"
}

To your bower.json file. Then run

bower install

var qr = new QRCode(typeNumber, correction, inputMode);
qr.addData(text);
qr.make();

var modules = qr.getModuleCount();

for (var row = 0; row < modules; row++) {
 for (var col = 0; col < modules; col++) {
 var color = qr.isDark(row, col) ? '#000' : '#fff';
 //...
 }
}
