☝❗Approach to versioning and breaking changes

This library is using semver and heavily relying on codegeneration. Many new features and/or bugfixes will require these files to be regenerated. Changes to codegenerated files will not be considered breaking unless they affect behavior of API or CLI.

Therefore every time this library is updated all files MUST be regenerated using rnuc command.

Mission

React-Native brings together 3 platforms: ios, android, javascript each of which have different conventions and approaches how to manage environment settings.

A typical app is usually operating in some environment defined by server urls various api keys or feature flags. When dealing with react-native such things often need to exist in 3 places: ios, android and js code. Even managing things as simple as application name or bundle id needs to be done in 2 places: Info.plist and AndroidManifest.xml

react-native-ultimate-config tries to reduce friction in managing these things by abstracting away from nuances of native projects.

With react-native-ultimate-config it is possible to consume variables in every place of a typical react-native app:

• javascript
• native code
  • java
  • objective-c
• native build configuration
  • ios
    • build settings
    • infoplist
  • android
    • build config
    • string resources
    • project.ext
