# react-native-bundle-extractor

[![codecov](https://codecov.io/gh/jmp/react-native-bundle-extractor/branch/master/graph/badge.svg)](https://codecov.io/gh/jmp/react-native-bundle-extractor)

This is a small utility for extracting the [React Native][1] JavaScript bundle

file from an Android APK. It can fetch the bundle either from an APK file

on the disk, or from an Android package installed on a connected device

(including Android virtual devices), without requiring deep knowledge of

the Android Debug Bridge (ADB).

Since React Native JavaScript bundles are typically minified, the tool

also runs it through [jsbeautifier][2] to get a more human-readable output.

The purpose of this tool is to give you a better idea of what your release

code will look like. It may convince you to obfuscate your JavaScript bundles. 

## Installation

    pip install -r requirements.txt

[Python](https://python.org/) 3.8 or later is recommended.

## Usage

To extract the bundle from an APK:

    python extract.py foo.apk

To extract the bundle from connected device using `adb`:

    python extract.py com.package.someapp

To customize the bundle filename, you can pass an additional parameter:

    python extract.py com.package.someapp --bundle index.android.bundle

## Run tests

    pytest
