Determine in code if app runs in Expo Go or not (in production build)

I would like to determine in react native code if the app is running in Expo Go or as a stand-alone iOS/Android app.

I can’t use __DEV__, because I would like to be able to determine this also for a production build.

in case you are using EAS Builds with TypeScript and since ExecutionEnvironment is an enum that looks like that:

export enum ExecutionEnvironment { 
Bare = 'bare', Standalone = 'standalone', StoreClient = 'storeClient'}

the correct way to determine current environment will be:

Constants.executionEnvironment === ExecutionEnvironment.Standalone

or for Bare React Native Apps:

Constants.executionEnvironment === ExecutionEnvironment.Bare

Since classic builds are now deprecated and everyone will start using EAS Builds, you will need to use Constants.ExecutionEnvironment instead of appOwnership which is always null in builds done via EAS.

So you could use the following to check if in production:

ExecutionEnvironment.Standalone ＝== "standalone"

You can use Expo's AppOwnership from Constants

import Constants from 'expo-constants'

const isRunningInExpoGo = Constants.appOwnership === 'expo'
