Beta/Preview Releases

Beta versions use .preview suffix (e.g., 55.0.0-preview.2), published under @next tag.

Check if latest is beta: https://exp.host/--/api/v2/versions (look for -preview in expoVersion)

npx expo install expo@next --fix  # install beta

Step-by-Step Upgrade Process

1. Upgrade Expo and dependencies

npx expo install expo@latest
npx expo install --fix

2. Run diagnostics: npx expo-doctor

3. Clear caches and reinstall

npx expo export -p ios --clear
rm -rf node_modules .expo
watchman watch-del-all

Breaking Changes Checklist

• Check for removed APIs in release notes
• Update import paths for moved modules
• Review native module changes requiring prebuild
• Test all camera, audio, and video features
• Verify navigation still works correctly

Prebuild for Native Changes

If upgrading requires native changes:

npx expo prebuild --clean

This regenerates the ios and android directories. Ensure the project is not a bare workflow app before running this command.

Clear caches for bare workflow

• Clear the cocoapods cache for iOS: cd ios && pod install --repo-update
• Clear derived data for Xcode: npx expo run:ios --no-build-cache
• Clear the Gradle cache for Android: cd android && ./gradlew clean

Housekeeping

• Review release notes for the target SDK version at https://expo.dev/changelog
• If using Expo SDK 54 or later, ensure react-native-worklets is installed — this is required for react-native-reanimated to work.
• Enable React Compiler in SDK 54+ by adding "experiments": { "reactCompiler": true } to app.json — it's stable and recommended
• Delete sdkVersion from app.json to let Expo manage it automatically
• Remove implicit packages from package.json: @babel/core, babel-preset-expo, expo-constants.
• If the babel.config.js only contains 'babel-preset-expo', delete the file
• If the metro.config.js only contains expo defaults, delete the file

Deprecated Packages

When migrating deprecated packages, update all code usage before removing the old package. For expo-av, consult the migration references to convert Audio.Sound to useAudioPlayer, Audio.Recording to useAudioRecorder, and Video components to VideoView with useVideoPlayer.

expo.install.exclude

Check if package.json has excluded packages:

{
  "expo": { "install": { "exclude": ["react-native-reanimated"] } }
}

Exclusions are often workarounds that may no longer be needed after upgrading. Review each one.

Removing patches

Check if there are any outdated patches in the patches/ directory. Remove them if they are no longer needed.

Postcss

• autoprefixer isn't needed in SDK +53. Remove it from dependencies and check postcss.config.js or postcss.config.mjs to remove it from the plugins list.
• Use postcss.config.mjs in SDK +53.

Metro

Remove redundant metro config options:

• resolver.unstable_enablePackageExports is enabled by default in SDK +53.
• experimentalImportSupport is enabled by default in SDK +54.
• EXPO_USE_FAST_RESOLVER=1 is removed in SDK +54.
• cjs and mjs extensions are supported by default in SDK +50.
• Expo webpack is deprecated, migrate to Expo Router and Metro web.

New Architecture

The new architecture is enabled by default, the app.json field "newArchEnabled": true is no longer needed as it's the default. Expo Go only supports the new architecture as of SDK +53.
