Raw Blame History

New Architecture

The New Architecture is enabled by default in Expo SDK 53+. It replaces the legacy bridge with a faster, synchronous communication layer between JavaScript and native code.

Documentation

Full guide: https://docs.expo.dev/guides/new-architecture/

What Changed

JSI (JavaScript Interface) — Direct synchronous calls between JS and native
Fabric — New rendering system with concurrent features
TurboModules — Lazy-loaded native modules with type safety

SDK Compatibility

SDK Version	New Architecture Status
SDK 53+	Enabled by default
SDK 52	Opt-in via app.json
SDK 51-	Experimental

Configuration

New Architecture is enabled by default. To explicitly disable (not recommended):

{
  "expo": {
    "newArchEnabled": false
  }
}

Expo Go

Expo Go only supports the New Architecture as of SDK 53. Apps using the old architecture must use development builds.

Common Migration Issues

Native Module Compatibility

Some older native modules may not support the New Architecture. Check:

Module documentation for New Architecture support
GitHub issues for compatibility discussions
Consider alternatives if module is unmaintained

Reanimated

React Native Reanimated requires react-native-worklets in SDK 54+:

npx expo install react-native-worklets

Layout Animations

Some layout animations behave differently. Test thoroughly after upgrading.

Verifying New Architecture

Check if New Architecture is active:

import { Platform } from "react-native";

// Returns true if Fabric is enabled
const isNewArch = global._IS_FABRIC !== undefined;

Verify from the command line if the currently running app uses the New Architecture: bunx xcobra expo eval "_IS_FABRIC" -> true

Troubleshooting

Clear caches — npx expo start --clear
Clean prebuild — npx expo prebuild --clean
Check native modules — Ensure all dependencies support New Architecture
Review console warnings — Legacy modules log compatibility warnings
