@chiacy please can you show me how you made it work for you

You use this as you would in any other Vue app. Quasar changes none of that. Since you probably want a single cache instance in your app, you probably should put it in a dedicated file. // cache.js const cache = new CordovaFileCache(OptionsObject) export default cache // usage in components import cache from './path/to/cache'

So in the end I solved it with the phonegap-plugin-barcodescanner, which is very similar to the cordova-plugin-barcodescanner, but you can configure it, so it feels more like a QR scanner. Be aware that it the two above internally (in cordova) register/use the same name, so before changing from the cordova plugin to the phonegap one, remove it with the command below before adding the another one, so the build process won’t break. $ cordova plugin rm cordova-plugin-barcodescanner
