🔄 React Native Restart

Programmatically reload the JavaScript bundle / restart your React Native app at runtime.

iOS	Android

Common use cases: applying an RTL/LTR locale change, recovering from a fatal JS state, resetting the app after login/logout, or clearing in-memory state without asking the user to kill and reopen the app.

Features

• ✅ One call to restart — RNRestart.restart()
• ✅ iOS, Android & Windows support
• ✅ New Architecture (TurboModule/Fabric) and legacy architecture both supported
• ✅ Optional restart reason you can read back after the restart (getReason())
• ✅ Fully typed (TypeScript) with a codegen TurboModule spec

Platform & architecture support

Platform	Restart mechanism	Old Arch	New Arch
iOS	Reloads the JS bundle (RCTTriggerReloadCommandListeners)	✅	✅
Android	Full process restart (ProcessPhoenix)	✅	✅
Windows	Reloads the instance (ReactNativeHost.ReloadInstance)	✅	✅

On Android the whole process is restarted, so native state and the JS runtime are reinitialized. On iOS/Windows the JS bundle is reloaded in-process. The optional restart reason survives the restart and is returned by getReason() on the next launch.

Installation

npm install react-native-restart
# or
yarn add react-native-restart

Match the package version to your React Native version:

React Native	Install
>= 0.85	react-native-restart@latest
0.72 – 0.84	react-native-restart@0.0.28
0.62 – 0.71	react-native-restart@0.0.24
< 0.62	react-native-restart@0.0.17

Requirements (RN 0.85+): React 19.2+, Node 20.19+ / 22.13+ / 24.3+, iOS 15.1+ & Xcode 16.1+, Android API 24+ (SDK 36, Java 17, Gradle 9.3+), and — for Windows — react-native-windows 0.84+ (optional peer dependency).

Linking

Autolinking (React Native ≥ 0.60) handles everything:

• iOS: cd ios && pod install
• Android: no extra steps
• Windows: npx react-native autolink-windows (runs automatically as part of run-windows)

Manual installation (legacy React Native, without autolinking)

Android — android/settings.gradle

include ':react-native-restart'
project(':react-native-restart').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-restart/android')

android/app/build.gradle:

dependencies {
    implementation project(':react-native-restart')
}

Register the package in MainApplication:

import com.reactnativerestart.RestartPackage; // <--- import

// ...in getPackages():
new RestartPackage()

iOS (manual / CocoaPods)

Add to your ios/Podfile:

pod 'react-native-restart', :path => '../node_modules/react-native-restart'

Then cd ios && pod install. (For very old projects you can instead drag Restart.xcodeproj from node_modules/react-native-restart/ios into your Xcode Libraries group and link libRestart.a.)

Usage

import RNRestart from 'react-native-restart';

// Restart the app (reloads the JS bundle; full process restart on Android)
RNRestart.restart();

// Optionally attach a reason, then read it back after the restart
RNRestart.restart('language-change');
const reason = await RNRestart.getReason(); // => 'language-change'

API

Method	Description
restart(reason?: string): void	Restart the app. Preferred entry point.
Restart(reason?: string): void	Deprecated alias of restart (kept for backward compatibility).
getReason(): Promise<string | null>	The reason passed to the last restart, or null. Survives the restart.

White screen during restart

Because restart() tears down the view hierarchy and remounts the app, there is a brief gap before the new instance renders — on iOS this can look like a white flash. To avoid it, set your root view's background color natively in AppDelegate:

- (UIView *)createRootViewWithBridge:(RCTBridge *)bridge
                          moduleName:(NSString *)moduleName
                           initProps:(NSDictionary *)initProps {
  UIView *rootView = [super createRootViewWithBridge:bridge moduleName:moduleName initProps:initProps];
  rootView.backgroundColor = [UIColor blackColor]; // your app's background color
  return rootView;
}

A full splash screen for the duration of the restart needs additional app-side native code (a native launch screen shown on app launch). See #238.

Architecture

A thin JS bridge (src/index.tsx + the TurboModule spec src/NativeRNRestart.ts) over native RNRestart modules on iOS (ios/), Android (android/), and Windows (windows/). Any public-API change must be made across the JS layer and every native platform together. For a full overview of structure, commands, build/publish flow, and conventions — for contributors and AI agents — see CLAUDE.md.

Testing

The library is tested across JS, native iOS, native Android, and end-to-end (Maestro), with each layer exercising the full restart/refresh flow. See TESTING.md for exactly what runs where and how to run it.
