🛠 react-native-config-reader

A native library to access all the native code's build configurations from JS.

Installation

1. $ npm install react-native-config-reader --save or $ yarn add react-native-config-reader

2. $ react-native link react-native-config-reader

3. Go to android/app/src/main/packageName/MainApplication.java and find line

   new RNConfigReaderPackage()

   and replace it with

   new RNConfigReaderPackage(BuildConfig.class)

See manual installation below if you have issues with react-native link.

Usage

import RNConfigReader from 'react-native-config-reader';

// access any of the defined config variables in andoird build gradle or ios info.plist
const configValue = RNConfigReader.ANY_DEFINED_CONFIG_FIELD;

More examples

Create new build config field inside android build.gradle file (android/app/build.gradle)

android {

    defaultConfig {
        applicationId "com.react-native.react-native-config-reader"
        versionCode 1
        versionName "1.0"
        
        buildConfigField "String", "TEST_CONFIG_FIELD", "Hello I'm your test config value"
    }
}

Create new field inside ios info.plist file

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0"> 
<dict>
  	<key>CFBundleDisplayName</key>
	<string>com.react-native.react-native-config-reader</string>
  
	<key>TEST_CONFIG_FIELD</key>
	<string>"Hello I'm your test config value"</string>
</dict>
</plist>

Now you can acess them inside the JS code

import { Platform } from 'react-native';
import RNConfigReader from 'react-native-config-reader';

if(Platform.OS === 'ios') {
  const iosBundleDisplayName = RNConfigReader.CFBundleDisplayName;
  const testConfigValue = RNConfigReader.TEST_CONFIG_FIELD;
}

if(Platform.OS === 'android') {
  const androidApplicationID = RNConfigReader.applicationId;
  const testConfigValue = RNConfigReader.TEST_CONFIG_FIELD;
}
