title: Scaning barcode with web cam into input field
body: <p>I want to implement barcode scaning into my web app and I want to use the web cam as scanner. So there is a field and a button. After clicking the button scanner opens and after successful scan the barcode is written in the input field. I searched and I couldn't find good tutorial how to do that. I tried using QuaggaJS barcode scanner written in JavaScript but it doesn't work.</p>
