Integrating Ionic in html web app


Currently, I have a responsive web application which is used in mobiles/tabs. I would like to scan some barcode/QR code from my application. As this is built on top of html and javascript, there are some limitations. And, I would need this to be as a web application, not a native mobile app.
Is it possible that, if I use the ionic framework, I can accomplish this? I couldn’t see any such details. Could you please help?
