This is a port to npm of Lazar Laszlo's port of ZXing qrcode scanner, http://code.google.com/p/zxing.

Usage

qrcode = require('zxing');
qrcode.decode([uri, ]function(err, result) {
  if (err != null) {
    console.log(err); // Will output any errors found
    return;
  }
  console.log(result); // Will output the decoded information
});

If uri is not passed, will instead extract image data from a canvas element with id="qr-canvas"

new from 2014.01.09 For webcam qrcode decoding (included in the test.html) you will need a browser with getUserMedia (WebRTC) capability.
