Going where no QRCode has gone before.

Basic Example

Node Library

Install

and used:

var qrcode = require('qrcode-terminal');

Usage

To display some data to the terminal just call:

qrcode.generate('This will be a QRCode, eh!');

You can even specify the error level (default is 'L'):

qrcode.setErrorLevel('Q');

qrcode.generate('http://github.com', function (qrcode) {
    console.log(qrcode);
});

If you want to display small output, provide opts with small:

qrcode.generate('This will be a small QRCode, eh!', {small: true});

qrcode.generate('This will be a small QRCode, eh!', {small: true}, function (qrcode) {
    console.log(qrcode)
});
