Upgrading Expo SDK
We recommend upgrading SDK versions incrementally, one at a time. Doing so will help you pinpoint breakages and issues that arise during the upgrade process.
Expo maintains ~6 months of backward compatibility. Once an SDK version has been deprecated, you will no longer be able to use the Expo Go app.
However, you will still be able to publish updates via eas update, and build using eas build. Deprecations will not affect standalone apps you have in production.
- There are a few small breaking API changes with this release. See the changelog for the full list.
- You will need to update your imports to match the new modular format. For example, if you currently have
import { FileSystem } from 'expo';, you will need to run expo install expo-file-system and then change your import to import * as FileSystem from 'expo-file-system';. We provide a codemod to help automate this.

}
- Delete your project’s node_modules directory and run npm install again
View.propTypes has been removed from React Native, so if your code (or any of your dependent libraries) uses it, that will break. Use ViewPropTypes instead. We strongly recommend running your app with the dev flag disabled to test whether it’s affected by this change.- We changed the format of
Constants.linkingUri (see Linking changes above), so if your code makes assumptions about this, you should double check that.
- Camera roll permissions are now required to use ImagePicker.launchCameraAsync() and ImagePicker.launchImageLibraryAsync(). You can ask for them by calling
Permissions.askAsync(Permissions.CAMERA_ROLL).
- In app.json, change sdkVersion to
"26.0.0"
- In package.json, change these dependencies:
{
"react-native": "https://github.com/expo/react-native/archive/sdk-26.0.0.tar.gz",

"react": "16.3.0-alpha.1"
}
- Delete your project’s node_modules directory and run npm install again
Expo.Util is deprecated, functionality has been moved out to Expo.DangerZone.Localization and Expo.Updates.ios.loadJSInBackgroundExperimental is now deprecated, use the new Updates API instead. The equivalent of this configuration is updates.fallbackToCacheTimeout: 0.isRemoteJSEnabled is also deprecated, use updates.enabled instead.- React Native 0.54 depends on React 16.3.0-alpha.1. React 16.3 deprecates the usage of
componentWillMount, componentWillReceiveProps, and componentWillUpdate. These have been replaced with static lifecycle methods: getDerivedStateFromProps and getSnapshotBeforeUpdate, but only getDerivedStateFromProps is available in 16.3.0-alpha.1.
- On iOS,
WebBrowser.dismissBrowser() promise now resolves with {type:'dismiss} rather than {type:'dismissed'} to match Android
- AdMob method name changes.
requestAd to requestAdAsync, showAd to showAdAsync, isReady to getIsReadyAsync.
- On iOS, Contacts
urls was renamed to urlAddresses to match Android. Related commit.
- On iOS, calling
Notifications.getExpoPushToken() will throw an error if you don’t have permission to send notifications. We recommend call Permissions.getAsync(Permissions.NOTIFICATIONS) and, if needed and you haven’t asked before, Permissions.askAsync(Permissions.NOTIFICATIONS) before getting push token.
- React Native 0.53.0 removed the TextInput autoGrow prop. Commit.
- In app.json, change sdkVersion to
"25.0.0"
- In package.json, change these dependencies:
{
"react-native": "https://github.com/expo/react-native/archive/sdk-25.0.0.tar.gz",
"expo": "^25.0.0",
"react": "16.2.0"
}
- Delete your project’s node_modules directory and run npm install again
- If you have any scripts in your project that depend on
metro-bundler, you will need to change those to metro (related commit). A likely place for this is in rn-cli.config.js.
- Although not technically part of the SDK, React Navigation is commonly used by Expo users, and it’s worth mentioning that on Android React Navigation now properly accounts for the translucent status bar. This may require you to remove code that you have to workaround that (maybe a paddingTop somewhere to avoid the content from rendering underneath the status bar). Read the React Navigation release notes for more information. Only applies to
react-navigation@1.0.0-beta.26 and higher.
- In app.json, change sdkVersion to
"24.0.0"
- In package.json, change these dependencies:
{
"react-native": "https://github.com/expo/react-native/archive/sdk-24.0.0.tar.gz",
"expo": "^24.0.0",
"react": "16.0.0"
}
- Delete your project’s node_modules directory and run npm install again
The following APIs have been removed after being deprecated for a minimum of 2 releases:
Expo.LegacyAsyncStorageExpo.Font.style- Passing an object into
Expo.SQLite.openDatabase() instead of separate arguments is no longer supported.
- In app.json, change sdkVersion to
"23.0.0"
- In package.json, change these dependencies:
{
"react-native": "https://github.com/expo/react-native/archive/sdk-23.0.0.tar.gz",
"expo": "^23.0.0",
"react": "16.0.0"
}
- Delete your project’s node_modules directory and run npm install again
- React Native no longer supports nesting components inside of
<Image> — some developers used this to use an image as a background behind other views. To fix this in your app, replace the Image component anywhere where you are nesting views inside of it with the ImageBackground component, like this:
<View style={styles.container}>
<ImageBackground
source={require('./path/to/image.png')}
style={{
width: 280,
alignItems: 'center',
justifyContent: 'center',
padding: 30,
}}>
<Text style={{ color: '#fff', fontSize: 18 }}>
The universe... what a concept. You know, the universe is a little bit like the human hand.
For example, you have groundmen's center right here and then you have undiscovered worlds and
uh, um and sector 8 and up here is tittleman's crest so you can kinda picture it's a little
bit like a leaf or uhh, umm, it's not a bowl.
</Text>
</ImageBackground>
</View>
- React Native now defaults
enableBabelRCLookup (recursive) to false in Metro bundler (the default bundler for React Native). This is unlikely to cause any problems for your application — in our case, this lets us remove a script to delete nested .babelrc files from node_modules in our postinstall. If you run into transform errors when updating your app, read this commit message for more information and to see how to opt-in to the old behavior.
- In app.json, change sdkVersion to
"22.0.0"
- In package.json, change these dependencies:
{
"react-native": "https://github.com/expo/react-native/archive/sdk-22.0.1.tar.gz",
"expo": "^22.0.0",
"react": "16.0.0-beta.5"
}
- Delete your project’s node_modules directory and run npm install again
Metro Bundler (the default React Native bundler) now errors (instead of silently ignoring) dynamic requires. In particular this breaks an older version of moment.js if you were using that (or indirectly depending on it).
Several deprecated APIs have been removed. All of these APIs printed warning messages in previous releases:
Expo.Notifications.getExponentPushToken is now Expo.Notifications.getExpoPushToken.Expo.AdMob.AdMobInterstitials.tryShowNewInterstitial has been removed in favor of requestAd and showAd.Expo.Segment.initializeAndroid and initializeIOS have been removed in favor of Expo.Segment.initialize.- The
tintEffect prop of Expo.BlurView has been removed in favor of the tint prop.
Expo.SecureStore.setValueWithKeyAsync, getValueWithKeyAsync, and deleteValueWithKeyAsync are now setItemAsync, getItemAsync, and deleteItemAsync. The order of arguments to setValueWithKeyAsync changed from (value, key) to (key, value).- The
callback prop of Expo.Video and Expo.Audio is now onPlaybackStatusUpdate.
This is not a breaking change yet but we plan to remove LegacyAsyncStorage in SDK 24.
If you, or any libraries that you use. use View.propTypes.style you will need to change that to ViewPropTypes.style.
If you have not yet updated your imports of
PropTypes as warned in deprecation warnings in previous releases, you will need to do this now. Install the
prop-types package and
import PropTypes from 'prop-types'; instead of
import { PropTypes } from React;!
Similarly, if you depend on
React.createClass, you will need to install the
create-react-class package and
import createReactClass from 'create-react-class'; as described in the React documentation.
- In app.json, change sdkVersion to
"21.0.0"
- In package.json, change these dependencies:
{
"react-native": "https://github.com/expo/react-native/archive/sdk-21.0.2.tar.gz",
"expo": "^21.0.0",
"react": "16.0.0-alpha.12"
}
- Delete your project’s node_modules directory and run npm install again
Camera
-
The takePicture function is now called takePictureAsync and now returns an object with many keys, instead of just returning the URI. The URI is available under the uri key of the returned object.
-
Previously this function would return a value like: "file://path/to/your/file.jpg"
-
And will now return an object like: { "uri": "file://path/to/your/file.jpg" }
Secure Store
setValueWithKeyAsync → setItemAsync: The order of the arguments has been reversed to match typical key-value store APIs. This function used to expect (value, key) and now expects (key, value).getValueWithKeyAsync → getItemAsync: Trying to retrieve an entry that doesn’t exist returns null instead of throwing an error.deleteValueWithKeyAsync → deleteItemAsync
Payments
- We had previously announced Stripe support on iOS as part of our experimental DangerZone APIs. The Payments API was using the Stripe SDK on iOS. We learned that Apple sometimes rejects apps which contain the Stripe SDK but don’t offer anything for sale. To help your App Review process go more smoothly, we have decided to remove the Stripe SDK and experimental Payments API from apps built with the Expo standalone builder. We are still excited to give developers a way to let users pay for goods when they need to and we will announce more ways to do so shortly.
