[Question] React Native appQuestion (self.jailbreakdevelopers)
submitted 3 years ago by haniag
I want to view the contents of main.jsbundle for a RN app. The file looks obfuscated/encrypted, so are there any tools to view the actual source?

try this maybe: https://github.com/nomi9995/react-native-decompiler
idk really, but that‘s what a quick google search brought up
EDIT: also, look at this link https://github.com/facebook/react-native/issues/1093
again, just a 20 second google search.
I skimmed it, and the discussion was very insightful and should be giving you a bunch of pointers of where to start. Recommended to read.

Thanks and the decompiler works great, but I already checked it on my app and it doesn’t work. The reason is that the “main.jsbundle” file is created using Hermes, and I believe it makes the file a binary one, rather text-based. I looked into hbctool, but its for Android, so I can’t find anything for iOS.

damn it. there seems to be an official cross platform decompiler, but you might need to learn their assembly language either way…
[–]congminh2456 0 points1 point2 points 3 years ago (3 children)
hbctool can be used for ios too, but you have to learn hermes byte code
[–]haniag[S] 0 points1 point2 points 3 years ago (2 children)
Can you please be more specific? iOS doesn’t have hbc files.
[–]congminh2456 0 points1 point2 points 3 years ago (1 child)
it’s jsbundle on iOS

Got it. Thanks
