            How do I retrieve the data from a scanned QR Code?
            Asked 2021-Aug-01 at 06:56

            I'm practicing on how to generate a QR code based on the userID of the current user. And once the QR code of the specific user is scanned, it will display the account details of that user. I'm just practicing so I could be familiar with how this process works.

            The auth.currentUser is null when there is no user logged in. Before generating the QR code, you should check if the user is logged in.

            I was aware that the "--max-old-space-size=8192" parameter does not pass to build. So I dedided to add ENV in Dockerfile like " ENV NODE_OPTIONS="--max-old-space-size=8192"". Finally my Dockerfile transformed to:

            If you want to extend react-qr-scanner you should fork it on github, you could import in locally to test and then publish it if you like, you could use as a private repo too
