Question: How obfuscated is react native code by default? #8

Open jay-jlm opened 5 years ago

jay-jlm commented 5 years ago

I read on stack overflow that some obfuscation is already achieved by default in React Native during bundling/minification phase but I have not confirmed it. Do you happen to have more information or any links about this? I'm curious about how much I get by default and how much I would get from a library such as this one. Thank you.

Last I checked react-native only minifies code and does some other trivial optimisations like constant folding. That does obfuscate a tiny bit, but nowhere near enough to deter reverse engineering.

Thanks. A quick final question: can/should this lib be used also while sharing a debug view with a third party? Or is useful for release builds only? Maybe the dev build has some additional elements like source maps etc that cannot be obfuscated?
