react-native-restart is a small React Native native module that programmatically reloads the running JS bundle at runtime — a full process restart on Android, a bundle reload in-process on iOS and Windows. The architecture is a deliberately thin TypeScript bridge (src/index.tsx) over three native implementations, all registered under the module name RNRestart. The JS layer resolves the native module through TurboModuleRegistry on the New Architecture with a NativeModules fallback for the legacy bridge, and throws a descriptive linking error when the module was never linked. A TurboModule spec (src/NativeRNRestart.ts) drives RN codegen on Android and Windows. The public API is just three calls: restart(reason?), the deprecated Restart(reason?) alias, and getReason() which returns a reason that survives the restart.
