If you are installing this in an existing React Native app, start by installing expo in your project. Then, follow the additional instructions as mentioned by the library's README under "Installation in bare React Native projects" section.

Usage

It is important that you follow the Human Interface Guidelines for iOS and Guidelines for Android when using this API.

Specifically:

Don't call StoreReview.requestReview() from a button - instead try calling it after the user has finished some signature interaction in the app.
Don't spam the user.
Don't request a review when the user is doing something time sensitive like navigating.
Don't ask the user any questions before or while presenting the rating button or card.

Write reviews

Android

There is no equivalent redirect on Android, you can still open the Play Store to the reviews sections using the query parameter showAllReviews=true like this:

Android Play Store example

const androidPackageName = 'host.exp.exponent';
// Open the Android Play Store in the browser -> redirects to Play Store on Android
Linking.openURL(
  `https://play.google.com/store/apps/details?id=${androidPackageName}&showAllReviews=true`
);
// Open the Android Play Store directly
Linking.openURL(`market://details?id=${androidPackageName}&showAllReviews=true`);

iOS

You can redirect an app user to the "Write a Review" screen for an app in the iOS App Store by using the query parameter action=write-review. For example:

iOS App Store example

const itunesItemId = 982107779;
// Open the iOS App Store in the browser -> redirects to App Store on iOS
Linking.openURL(`https://apps.apple.com/app/apple-store/id${itunesItemId}?action=write-review`);
// Open the iOS App Store directly
Linking.openURL(
  `itms-apps://itunes.apple.com/app/viewContentsUserReviews/id${itunesItemId}?action=write-review`
);

API

import * as StoreReview from 'expo-store-review';

Methods

`StoreReview.hasAction()`

Returns:

Promise<boolean>

This returns a promise that fulfills to true if StoreReview.requestReview() is capable directing the user to some kind of store review flow. If the app config (app.json) does not contain store URLs and native store review capabilities are not available then the promise will fulfill to false.

Example

if (await StoreReview.hasAction()) {
  // you can call StoreReview.requestReview()
}

`StoreReview.isAvailableAsync()`

Determines if the platform has the capabilities to use StoreReview.requestReview().

Returns:

Promise<boolean>

This returns a promise fulfills with boolean, depending on the platform:

On iOS, it will resolve to true unless the app is distributed through TestFlight.
On Android, it will resolve to true if the device is running Android 5.0+.
On Web, it will resolve to false.

`StoreReview.requestReview()`

In ideal circumstances this will open a native modal and allow the user to select a star rating that will then be applied to the App Store, without leaving the app. If the device is running a version of Android lower than 5.0, this will attempt to get the store URL and link the user to it.

Returns:

Promise<void>

`StoreReview.storeUrl()`

This uses the Constants API to get the Constants.expoConfig.ios.appStoreUrl on iOS, or the Constants.expoConfig.android.playStoreUrl on Android.

On Web this will return null.

Returns:

string | null

Error codes
