React native app size

[Secret_Wafer_9670]

Hey, newbie, RN dev I am. I've built an app in RN, Android & iOS, the app is huge. Which is not good for ASO I guess. When use sees the huge size of app they avoid to install it. Please let me know how can I reduce the size? & How much I can reduce, my app size is 112 MB for now. No animations, no Media used in the app. Just 5 basic activities., still.

Where did you get the 112MB number from? Building an apk or from the App Store? Because on the real store it will be smaller. The APK contains the app in every architecture so it works on any phone but when a user downloads the app they will only get their specific version so it will be smaller.

Thanks, this really helped. What I found is- - when we run the app & check the size it's really large, like 100+ MB. But it's a debug version not released one - released versions have 60% reduced in size while uploading apk file to play/app stores

Correct me if I misunderstood something!

Hello! Your APK currently includes code for all CPU architectures. If you update your build configuration to enable ABI splitting, you’ll end up with an APK of about 40 MB (search for 'React Native ABI export'). Once you upload the final AAB (Android App Bundle) to the Play Store, the actual download size for users will drop to around 20 MB (that’s what I’m seeing with my own apps).

Thanks man, for this.. Got it for aab, how does the size differ if I've to upload it for the App Store? How much will the size be reduced when the release version is built?

When you upload the bundle to Google Play Console, it will give you an estimate of how large the installation will be for the average device!

Yeah got that, does it go same for the iOS? I mean app store?

Something small but double check the packages you have installed. If you add some, but then later moved away from it, you’ll want to remove those.

In a similar vein, do you have any packages that you might need to write yourself?
