            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.



            Answered 2021-Aug-01 at 06:56

            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 am trying to build react prod docker container with Azure DevOps pipelines. After I upgrade my build environment and code, Pipeline failed. After some research I add "--node-flags --max-old-space-size=8192" statement my build command. But it didn't matter. I also try tried relevant node containers for a build, it didn't work.

            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:

            Problem : So I'm using this npm package react-qr-scanner to scan QR codes in my PWA. Now this is a react based package. The react component(just an example) is like:

            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
