Obfuscator.io Metro Plugin


This metro plugin obfuscate your React Native bundle using javascript-obfuscator

It only obfuscates your code not the code of node_modules, you can verify the obfuscated bundle by either extracting the index.android.bundle from generated apk
or you can find the file at project_root\android\app\build\generated\assets\react\release after assembleRelease process

#### for iOS if you’re facing any issue check this comment by @andresarezo
