React Native Expo Client SDK

DEPRECATED

To get started with Statsig in Expo, you should use the new Statsig Expo SDK.

This version of the SDK is deprecated and will only receive major bug fixes going forward.

If you already use this deprecated version, you should check out the migration docs.

Statsig client side SDK for applications in React Native using Expo. If you are not using Expo, check out our plain React Native SDK. This SDK is based on our JavaScript client SDK.

Installation​

You can install the SDK via npm or yarn. In your project directory, run:

npm install statsig-react-native-expo

Next you can import Statsig in your code and use it away!

import {
  StatsigProvider,
  useGate,
  useExperiment,
  useConfig,
  Statsig,
} from "statsig-react-native-expo";

If you run into build errors, see the FAQ below.

Usage​

v4.X.X of our react-native-expo SDK wraps the statsig-react sdk. It contains the same React Context, Providers, and Hooks, used in the same way. Get started with our suggested usage or the Provider and Hooks details.

info

Be sure to update the imports from the examples on the react SDK docs to use "statsig-react-native-expo" instead of "statsig-react"

FAQ​

If you get build errors when trying to install and use the SDK for the first time, you may need to install a few dependencies and rebuild with a clean cache. We've only encountered these errors when using eas to build an expo app, but perhaps there are other build tools that will be missing these dependencies.

For example:

Error: [@RNC/AsyncStorage]: NativeModule: AsyncStorage is null

Means you need to install the AsyncStorage dependency

npx expo install @react-native-async-storage/async-storage

And this:

ERROR  [Statsig] An unexpected exception occurred. [TypeError: Cannot read property 'getRandomBase64String' of undefined]

Means you need to install the random values depedency:

npx expo install expo-random

Finally, you can clear the cache in an eas build like this:

eas build -p ios --clear-cache

For non eas users, you may need to do a pod install in the ios folder of your app as well.
