I think instead of loading the book's data afresh, use filter based on selected item then share that information from books page to the IDs page. In this case, you will avoid re-rendering during useEffect promise resolution. I think useMemo will be helpful here.

Yes that's right, the performance could be improved a bit!

Hi, Simon. That's a great video. I built with you. And I add some other features like firebase login, fav books screen, other users books... its amazing but it is only work on expo. when I get apk and download the pyhscal phone or emulator. its crash on launch. do you have any idea

[@svepel]

I use the provided source code, I updated file with FirebaseConfig. But why when I try to add new book when scanning the book the following error comes:
Possible Unhandled Promise Rejection (id: 0):
TypeError: Cannot read property 'textSnippet' of undefined
TypeError: Cannot read property 'textSnippet' of undefined
How this can be corrected?

Simon, how did you route expo localhost to Firebase? Thanks for this tutorial.

[@galaxies_dev]

Not sure what you mean, I used the Firebase config as always!
