|
||
| ## 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`) | ||
|
|
||
| ```bash | ||
| npx expo install expo@next --fix # install beta | ||
| ``` | ||
|
|
||
| ## Step-by-Step Upgrade Process | ||
|
|
||
| > If upgrading from SDK 55 or earlier, skip SDK 56 and upgrade directly to SDK 57. Don't use `expo@57.0.8` or below. SDK 55 with Hermes V1 enabled, SDK 56, and older SDK 57 releases contain a Hermes V1 memory regression that can drastically increase memory usage when using `react-native-worklets` or `react-native-reanimated`. | ||
|
|
||
| 1. Upgrade Expo and dependencies | ||
|
|
||
| ```bash | ||
| npx expo install expo@latest | ||
| npx expo install --fix | ||
| ``` | ||
|
|
||
| 2. Run diagnostics: `npx expo-doctor` | ||
|
|
||
| 3. Clear caches and reinstall | ||
|
|
||
| ```bash | ||
| 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 | ||
|
|
||
| **First check if `ios/` and `android/` directories exist in the project.** If neither directory exists, the project uses Continuous Native Generation (CNG) and native projects are regenerated at build time — skip this section and "Clear caches for bare workflow" entirely. | ||
|
|
||
| If upgrading requires native changes: | ||
|
|
||
| ```bash | ||
| 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 | ||
|
|
||
| These steps only apply when `ios/` and/or `android/` directories exist in the project: | ||
|
|
||
| - 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 | ||
| - Update versioned docs links in agent instruction files (`AGENTS.md`). The default template links to `https://docs.expo.dev/versions/v<version>/`. Search for `docs.expo.dev/versions/` and bump each link to the new SDK version. | ||
| - 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 | ||
|
|
||
| | 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 | | ||
|
|
||
| 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: | ||
|
|
||
| ```json | ||
| { | ||
| "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](https://docs.expo.dev/router/migrate/from-expo-webpack/). | ||
|
|
||
| ## Hermes engine v1 | ||
|
|
||
| Hermes V1 is the default on SDK 56 and later. SDK 55 apps using Hermes V1, all SDK 56 apps, and SDK 57 apps before `expo@57.0.9` may encounter a memory regression when importing `react-native-worklets` or `react-native-reanimated`. Upgrade directly to SDK 57 and `expo@57.0.9` or later. Do not recommend Worklets Bundle Mode as a production workaround; it is unsupported and experimental and may not work as expected. | ||
|
|
||
| Do not guide users to opt in to or out of Hermes V1. Changing the Hermes version from the SDK default is unsupported and has significant build and dependency-management caveats. | ||
|
|
||
| ## 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. | ||
|
|
||
| ## Submitting Feedback | ||
|
|
||
| If you encounter errors, misleading or outdated information in this skill, report it so Expo can improve: | ||
|
|
||
| ```bash | ||
| npx --yes submit-expo-feedback@latest --category skills --subject "expo-upgrade" "<actionable feedback>" | ||
| ``` | ||
|
|
||
| Only submit when you have something specific and actionable to report. Include as much relevant context as possible. | ||
| If an AI agent repeatedly failed or the user had to take over an Expo task, load the expo-skill-feedback skill and follow its eval-candidate flow instead of reusing the command above. | ||
