React Native Decompiler [ALPHA]

A CLI for React Native that allows you to decompile JS code of Android and IOS.

DOES NOT SUPPORT ENCRYPTED/BINARY (FACEBOOK, INSTAGRAM) BUNDLES

Decompiles React Native index.android.bundle JS files. Webpack files too!

Also tries to remove some compilation artifacts (via internal plugins, ESLint, and Prettier) to make it easier to read.

$3

``sh
npx react-native-decompiler
`

$3

`sh
npm i -g react-native-decompiler
`

`sh
react-native-decompiler

or you can write blow command

rnd
`

Usage


Example 1: npx react-native-decompiler -i ./index.android.bundle -o ./output

Example 2: npx react-native-decompiler -i ./main.jsbundle -o ./output

Example 3: react-native-decompiler -i ./index.android.bundle -o ./output

Example 4: rnd -i ./index.android.bundle -o ./output

Command params:
- -i (required) - input file/folder
- -o (required) - the path to the output folder
- -e - a module ID, if specified will only decompile that module & it's dependencies.
- -p - performance monitoring flag, will print out runtime for each decompiler plugin
- -v - verbose flag, does not include debug logging (use DEBUG=react-native-decompiler:* env flag for that)
- --es6 - attempts to decompile to ES6 module syntax.
- --noEslint - does not run ESLint after doing decompilation
- --prettier - does not run Prettier after doing decompilation
- --unpackOnly - only unpacks the app with no other adjustments
- --decompileIgnored - decompile ignored modules (modules are generally ignored if they are flagged as an NPM module)
- --agressiveCache - skips some cache checks at the expense of possible cache desync
- --noProgress - don't show progress bar
- --debug - when also given a module ID, will print out that modules code after any plugin handles the app.

Android

Extract index.android.bundle from APK

$3

#### For Macbook
`
brew install apktool
`

#### For Linux
`
apt-get install -y apktool
`

#### For Window

you can read installion step for window DOCS

after install apktool, unzip apk file by run this command on terminal like this:

`
apktool d /pathOfApkFile.apk
`

After that you will get index.android.bundle file at pathOfApkFile/assets/index.android.bundle

than you can use react-native-decompiler for decompile index.android.bundle file


IOS

Extract main.jsbundle from IPA

you can unzip ipa by unzip command on terminal
`sh
$ unzip AppName.ipa
`
after unzip, you will get Playload folder, then you have to copy main.jsbundle file.
there are two ways to copy this file as follow below

1. run this command cp ./Payload/AppName.app/main.jsbundle ./ to get get main.jsbundle file

2. Go to Payload folder and right click on AppName.app and choose Show Package Contents then you will find main.jsbundle file at root. you can copy this file to any location

after getting main.jsbundle you can use react-native-decompiler for decompile main.jsbundle file

Valid inputs

The following input formats are currently supported:
- A single index.android.bundle/main.jsbundle file that contains all modules (most cases for React Native)
- A folder containing React Native modules (usually called js-modules) in "unbundled" apps
- A single Webpack entrypoint bundle file (entrypoint bundles begin with !function(e), chunked bundles start with window.webpackJsonp)
- A folder containg Webpack chunks, where at least one file is the entrypoint

Extending

The decompiler operates on a tagger -> editor -> decompiler system.

* Taggers - Manipulates the module metadata
* Editors - Manipulates the module lines (add, move, or remove).
* Decompilers - Manipulates the module code.

To add a new plugin, add it into the represpective list.

The plugins are initialized per module, so any data you store in your plugins will only persist for the current module.

If your plugin needs to be run before or after other plugins, adjust the ordering in the list, or modify it's pass position.

Guidelines:

* When doing any modifications to the AST, use the NodePath methods.
* When you are only doing reading, directly reading from .node` is acceptable.
