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.
Full guide: https://docs.expo.dev/guides/new-architecture/
| SDK Version | New Architecture Status |
|---|---|
| SDK 53+ | Enabled by default |
| SDK 52 | Opt-in via app.json |
| SDK 51- | Experimental |
New Architecture is enabled by default. To explicitly disable (not recommended):
{
"expo": {
"newArchEnabled": false
}
}Expo Go only supports the New Architecture as of SDK 53. Apps using the old architecture must use development builds.
Some older native modules may not support the New Architecture. Check:
React Native Reanimated requires react-native-worklets in SDK 54+:
npx expo install react-native-workletsSome layout animations behave differently. Test thoroughly after upgrading.
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
npx expo start --clearnpx expo prebuild --clean
