RNRepo

Software Mansion's infrastructure for pre-building and distributing React Native library artifacts, reducing native build times by up to 2× with zero infrastructure changes.

Read the relevant reference for the topic at hand. All references are in references/.

Key facts

  • Beta, New Architecture only. Works with React Native latest patches of 0.77, 0.78, 0.79 and all versions above 0.80.0.
  • How it works: A Gradle plugin (Android) and CocoaPods plugin (iOS) intercept the build and substitute libraries with prebuilt artifacts from packages.rnrepo.org. Falls back to source if a prebuild is unavailable.
  • Expo CNG: Use @rnrepo/expo-config-plugin — it configures both Android and iOS automatically.
  • Standard RN: Install @rnrepo/build-tools and edit android/build.gradle, android/app/build.gradle, and ios/Podfile manually.
  • Opt out per library: Add a rnrepo.config.json with a denyList at the project root. Required for libraries with native patches (Objective-C/Java/Kotlin). JS-only patches do NOT require opting out.
  • Opt out entirely: Set DISABLE_RNREPO=1 environment variable before the build command.
