title: How to scan Qr-code in angular 2 application?
body: <p>I am trying to create an application where it will scan a qr-code with angular-cli?
  I did found few npm modules like qrcode-reader. But any of them are working with angular 2. I guess, beacuse qrcode-reader more like nodejs server side module.
  Is there anyway to build the application?</p>
