Installation

npm install react-native-config-info
cd ios && pod install

Prerequisite

Add your values into your Info.plist (iOS) or strings.xml (Android).

iOS

ios/[project]/Info.plist

<?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>BackendUrl</key>
    <string>https://api.example.com</string>
</dict>
</plist>

Android

android/app/src/main/res/values/strings.xml

<resources>
    <string name="BackendUrl">https://api.example.com</string>
</resources>

Usage

Asynchronous getters

Get your values.

import ConfigInfo from 'react-native-config-info';

async function main() {
  await ConfigInfo.get('BackendUrl'); // https://api.example.com
  await ConfigInfo.getOrThrow('BackendUrl'); // https://api.example.com

  await ConfigInfo.get('UnknownKey'); // null
  await ConfigInfo.getOrThrow('UnknownKey'); // [RNConfigInfoException: 'UnknownKey' value is missing from ….]
}

Synchronous getters

Get your values synchronously.

As said in the official documentation, synchronous methods are not recommended.

Only use them if you have no other option.

import ConfigInfo from 'react-native-config-info';

ConfigInfo.getSync('BackendUrl'); // https://api.example.com
ConfigInfo.getSyncOrThrow('BackendUrl'); // https://api.example.com

ConfigInfo.getSync('UnknownKey'); // null
ConfigInfo.getSyncOrThrow('UnknownKey'); // [RNConfigInfoException: 'UnknownKey' value is missing from ….]
