Nice video, thanks :)

[@notjustdev]

Thanks

[@mosdev1663]

Hi, thanks for your content which I've been following for a while and which has greatly helped me evolve on React Native in general. Could you teach us how to test our React Native code with Jest or something else for Typescript without Expo? It would be really interesting to develop our know-how. Thank you very much for everything you do 👍

[@notjustdev]

Hey, thanks for the appreciation! You can check out this blog post we made about testing with Jest and Testing Library: www.notjust.dev/blog/2023-01-16-react-native-testing

[@tomoJP]

I think SWR is common on the web, but is it not so on mobile?

[@SuperYoda7]

I usually go with tanstack query and really like it. Is this an alternative?

[@notjustdev]

Yes, this is an alternative

[@user-ct5zv1gg5z]

Sir please help me which one to choose react native cli or expo cli. I have build more than 7 apps in expo, but for large scale app I want to use react native cli what do u suggest ❤❤❤

[@notjustdev]

I would still go with Expo

[@ibrahimkouma6751]

a quick question when building production app between tanstack vs swr which one do you suggest ?

[@notjustdev]

I haven't used SWR in production, but it seems pretty powerful

With Apollo and swr which one u suggest please and is there main difference? Coz in your course u used Apollo.
