React Native App Check

[Aurélien Houdbert]

Hello everyone !

I'm trying to use App Check on my react native app :)
this documentation (https://rnfirebase.io/app-check/usage) doesn't have much info on how to setup the package so I'm trying to follow this documentation instead (https://firebase.google.com/docs/app-check?hl=en). The issue mostly concerns the android part where I don't understand this section (https://firebase.google.com/docs/app-check/android/safetynet-provider?hl=en#initialize) and I don't know where I should put this piece of code in my react native project...

FirebaseApp.initializeApp(/*context=*/ this);
FirebaseAppCheck firebaseAppCheck = FirebaseAppCheck.getInstance();
firebaseAppCheck.installAppCheckProviderFactory(
        SafetyNetAppCheckProviderFactory.getInstance());

Does anyone has a clear tutorial on how to use app check under react native ?

Thanks a lot !

Hi,

attached you can see the Code that we are using at the moment:

firebaseApp = firebase.app();

dbApp = firebaseApp.firestore();

authApp = firebaseApp.auth();

functionsApp = firebaseApp.functions("europe-west1");

storageApp = firebaseApp.storage("gs://" + firebaseConfig.storageBucket);

realtimeDatabaseApp = firebaseApp.database(firebaseConfig.databaseURL);

analyticsApp = firebaseApp.analytics();

appCheckApp = firebaseApp.appCheck();

remoteConfigApp = firebaseApp.remoteConfig();

try {

if (Platform.OS === "ios") {

console.log("AppCheck activated by default");

await appCheckApp.activate("ignored", true);

} else await appCheckApp.activate("ignored", true);

} catch (e) {

console.log("error", e);

}

try {

let appCheckTokenResponse = await appCheckApp.getToken(

/* forceRefresh= */ false

);

console.log("appcheck", appCheckTokenResponse);

} catch (err) {

// Handle any errors if the token was not retrieved.

console.log("appcheck error", err);

}

Hi,

Thanks for your answer ! In which file did you insert this piece of code?

[Stephan Strecker]

we have an own class that is handling all backend interactions. this class is initiated at app start.

I assume you already have a place where you initiate your firebase instance. thats the place to do it also for appcheck
