I was waiting for this! Thanks.
I've found a bug: when creating a new project, the web preview inside idx does not compile. The web version seems to be working in the browser by opening the link.

2024-08-27T10:56:08Z [web] <IDX> ✘ Preview shutdown unexpectedly

Expo cli works fine here, we need react-native CLI support as well. Also, the emulator for it.

I tried it but getting this error

yes having react native is sure things along with flutter in the idx

i agree

Android emu + react native / expo
This would be great for 128gb MacBook owners and would allow developers to develop without mac/win/linux pc, for example on android tablets.
Would be a real lifesaver for me

React native support is very much needed

React native support is very much needed

can you add an expo template pls with android and ios previews

Yarn support would be good too

Also add support for both simulators like Android and IOS

Expo for react native support pls

expo please

i understand that react native is the competitor of google which is have flutter, but i think the popularity of the idx will be grow with adding react native.

For all the reasons mentioned already, and many others, please accelerate the support for react native with expo. I believe that would bring a ton of users on here

Adding support for react native with expo would be a fantastic thing, it would also allow you via github actions using eas to create and release android - ios builds without a mac.

We need react native too run in idx thats help developer plz implement

expo please

We already have support for React and Next.js and the android emulator in Flutter, it would be really nice to have support for React Native as well as a complement.
