react-native-config-bridge

The aim of this library is to read variables from Android and iOS native config with Javascript. This can be useful, for example, to know what buildType/flavor/configuration the current app has been built upon.

Getting started

npm install react-native-config-bridge

For RN 0.60 and upper

cd ios
pod install

For RN 0.59 and below

react-native link react-native-config-bridge

Usage

Android

1. Edit your android/app/build.gradle

   ...
   defaultConfig {
       ...
       buildConfigField('String', 'ENV_NAME', '"development"')
   }
   ...

2. Override your config field per buildType or flavor, if needed.

   ...
   buildTypes {
       ...
       release {
           ...
           buildConfigField('String', 'ENV_NAME', '"production"')
       }
   }
   ...

3. Enjoy.

iOS

1. Edit your ios/Info.plist

   ...
   <key>ENV_NAME</key>
   <string>$(BUILD_SETTING_NAME)</string>
   ...

2. Create a new build setting (BUILD_SETTING_NAME is a placeholder) in your target
3. Customize the build setting for each configuration, if needed.

Javascript

import RNConfig from 'react-native-config-bridge';

const envName = RNConfig.ENV_NAME;
