Tips for react-native upgrade to v0.58.4

#reactnative

What is the article

I tried upgrade react-native v0.57.7. to v0.58.4.

This article is the saga of upgrading.

At first, upgrade react-native to v0.58.4, , react to 16.6.1 and metro-react-native-babel-preset to 0.51.1 by yarn or npm.

You might meet errors when yarn react-native ios or android.

Additional steps here.

Mentioned from changelog, you need to link JavaScriptCore.framework as librariy by manual.

It's all done when my use case.

Upgrading for android is a bit complicated, follow the changelog

I met error of More than one file was found with OS independent path 'lib/x86_64/libjsc.so' same as this issue comment

So, I fixed errors by modifying build.gradle files.

The final result of files are following.

...
ext {
    ...
    buildToolsVersion = "28.0.2"
    compileSdkVersion = 28
    ...
}

android {
    ...
    packagingOptions {
        pickFirst 'lib/x86_64/libjsc.so'
        pickFirst 'lib/arm64-v8a/libjsc.so'
    }
    ...
}

I hope these tips are helpful for you.
Have a habby react-native developing!

Thanks for the guide! The packingOptions didn't work for me. I used this github.com/react-native-community/...
