Guidelines for upgrading Expo SDK versions and fixing dependency issuesFrom its SKILL.md

One thing to look at
- no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
What its file declares
Copied from the file, not written here
The file declares its own license as MIT. That is the author’s claim about this one file, and it is not the same thing as the license GitHub reports for the repository, which is listed with the other numbers below.

Step-by-Step Upgrade Process
- Upgrade Expo and dependencies
npx expo install expo@latest
npx expo install --fix
-
Run diagnostics:
npx expo-doctor -
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.jsonto 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
| Old Package | Replacement |
|---|---|
expo-av | expo-audio and expo-video |
expo-permissions | Individual package permission APIs |
@expo/vector-icons | expo-symbols (for SF Symbols) |
AsyncStorage | expo-sqlite/localStorage/install |
expo-app-loading | expo-splash-screen |
| expo-linear-gradient | experimental_backgroundImage + CSS gradients in View |
Removing patches
Check if there are any outdated patches in the patches/ directory. Remove them if they are no longer needed.
Postcss
autoprefixerisn't needed in SDK +53.- Use
postcss.config.mjsin SDK +53.
Metro
Remove redundant metro config options:
- resolver.unstable_enablePackageExports is enabled by default in SDK +53.
experimentalImportSupportis enabled by default in SDK +54.EXPO_USE_FAST_RESOLVER=1is 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.
