We thought the same at first and also tried a light blue, which looked a bit off. The difficulty in this scenario is that the app already is very colorful already and we need something that stands out.

It’s amazing how easy it is these days to build a custom flow for over-the-air updates.
Just take the useUpdates hook from Expo Updates and wrap a nice little UI around it.
Smooth banner → update check → ready state → tap → reload.
Awesome, isn't it?

I’m super happy that we have another client for which we can migrate from react-native-cli to the Expo Prebuild / CNG workflow 😌

Great job. That looks awesome!
Also the solution isn't even too complex.
Actually this is technically quite similar to this animation, I build a while ago.

One month of intense work and preparation, one month of parental leave. Time flies! But now I’m back in daily business.

To understand why this is so important, I created a simple graph, as many people don’t realize how much time can be saved. Feel free to show that to your manager!
From our experience, 80–90% of the effort in an upgrade is updating native files. With Expo, you don’t have to think about them at all.

And we did it with build number 1. The very first build we submitted was approved by the App Store review team. Sure, it’s “just” for TestFlight, but seeing that approval on the first try felt so impressive 💪

Haha, this is fun! I find it fascinating how close its interpretation comes to what I actually aim for here. And the dating version — so funny. A hackathon date? Seems like AI still has a lot to learn about dating 😅

This is the first time I’ve seen a component defined as a variable to reuse the name for the memoized version — interesting approach.
