ReferenceError: Cannot access 'QRCodesDB' before initialization

[DeonLeer]

I'm unable to run the QRCode node example app. It says that the QRCodesDB object cannot be accessed before initialization. There seems to be a circular dependency as the shopify object in the web/shopify.js file is required in the qr-codes-db.js file and vice versa
