                React Native Security - this compilation were initially built upon a help request about security for a banking app.
              
          
    Obfuscate code helps.


JS Bundles

https://github.com/vesselsoft/metro-minify-obfuscator
https://github.com/jscrambler/jscrambler/tree/master/packages/jscrambler-metro-plugin
https://github.com/MichaelXF/js-confuser - Adding this here as a note, because it could end up better than the javascript-obfuscator, but it might require a RN / Metro implementation with a working sourcemap 1 / 2 support.
If using RePack, simply enable HermesBytecodePlugin.


Android

Proguard / R8


iOS
Before deprecation, BITCODE was used. However there is a commercial one called iXGuard.
