Getting Started

Prepare Frontegg workspace

Navigate to Frontegg Portal Settings, If you don't have application
follow integration steps after signing up.
Copy FronteggDomain to future steps from Frontegg Portal Domain

Setup Hosted Login

• Navigate to Login Method Settings
• Toggle Hosted login method
• Add {{IOS_BUNDLE_IDENTIFIER}}://{{FRONTEGG_BASE_URL}}/ios/oauth/callback
• Add {{ANDROID_PACKAGE_NAME}}://{{FRONTEGG_BASE_URL}}/android/oauth/callback
• Replace IOS_BUNDLE_IDENTIFIER with your application identifier
• Replace FRONTEGG_BASE_URL with your frontegg base url
• Replace ANDROID_PACKAGE_NAME with your android package name

Add frontegg package to the project

Use a package manager npm/yarn to install frontegg React Native library.

NPM:

npm install -s @frontegg/react-native

Yarn:

yarn add @frontegg/react-native

Setup iOS Project

Create Frontegg plist file

To setup your SwiftUI application to communicate with Frontegg, you have to create a new file named Frontegg.plist under
your root project directory, this file will store values to be used variables by Frontegg SDK:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>baseUrl</key>
	<string>https://[DOMAIN_HOST_FROM_PREVIOUS_STEP]</string>
	<key>clientId</key>
	<string>[CLIENT_ID_FROM_PREVIOUS_STEP]</string>
</dict>
</plist>

Config iOS associated domain

Configuring your iOS associated domain is required for Magic Link authentication / Reset Password / Activate Account.

In order to add your iOS associated domain to your Frontegg application, you will need to update in each of your integrated Frontegg Environments the iOS associated domain that you would like to use with that Environment. Send a POST request to https://api.frontegg.com/vendors/resources/associated-domains/v1/ios with the following payload:

{
    “appId”:[YOUR_ASSOCIATED_DOMAIN]
}

In order to use our API’s, follow this guide to generate a vendor token.

Setup Android Project

Set minimum sdk version

To set up your Android minimum sdk version, open root gradle file atandroid/build.gradle,
and add/edit the minSdkVersion under buildscript.ext:

buildscript {
    ext {
        minSdkVersion = 26
        // ...
    }
}

Configure build config fields

To set up your Android application on to communicate with Frontegg, you have to add buildConfigField property the gradle android/app/build.gradle.
This property will store frontegg hostname (without https) and client id from previous step:

def fronteggDomain = "FRONTEGG_DOMAIN_HOST.com" // without protocol https://
def fronteggClientId = "FRONTEGG_CLIENT_ID"

android {
    defaultConfig {

        manifestPlaceholders = [
                "package_name" : applicationId,
                "frontegg_domain" : fronteggDomain,
                "frontegg_client_id": fronteggClientId
        ]

        buildConfigField "String", 'FRONTEGG_DOMAIN', "\"$fronteggDomain\""
        buildConfigField "String", 'FRONTEGG_CLIENT_ID', "\"$fronteggClientId\""
    }
    
    
}

Add bundleConfig=true if not exists inside the android section inside the app gradle android/app/build.gradle

android {
  buildFeatures {
    buildConfig = true
  }
}

Add permissions to AndroidManifest.xml

Add INTERNET permission to the app's manifest file.

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.POST_NOTIFICATIONS" />

Config Android AssetLinks

Configuring your Android AssetLinks is required for Magic Link authentication / Reset Password / Activate Account /
login with IdPs.

To add your AssetLinks to your Frontegg application, you will need to update in each of your integrated Frontegg
Environments the AssetLinks that you would like to use with that Environment. Send a POST request
to https://api.frontegg.com/vendors/resources/associated-domains/v1/android with the following payload:

{
    "packageName": "YOUR_APPLICATION_PACKAGE_NAME",
    "sha256CertFingerprints": ["YOUR_KEYSTORE_CERT_FINGERPRINTS"]
}

Each Android app has multiple certificate fingerprint, to get your DEBUG sha256CertFingerprint you have to run the
following command:

For Debug mode, run the following command and copy the SHA-256 value

NOTE: make sure to choose the Variant and Config equals to debug

./gradlew signingReport

###################
#  Example Output:
###################

#  Variant: debug
#  Config: debug
#  Store: /Users/davidfrontegg/.android/debug.keystore
#  Alias: AndroidDebugKey
#  MD5: 25:F5:99:23:FC:12:CA:10:8C:43:F4:02:7D:AD:DC:B6
#  SHA1: FC:3C:88:D6:BF:4E:62:2E:F0:24:1D:DB:D7:15:36:D6:3E:14:84:50
#  SHA-256: D9:6B:4A:FD:62:45:81:65:98:4D:5C:8C:A0:68:7B:7B:A5:31:BD:2B:9B:48:D9:CF:20:AE:56:FD:90:C1:C5:EE
#  Valid until: Tuesday, 18 June 2052

For Release mode, Extract the SHA256 using keytool from your Release keystore file:

keytool -list -v -keystore /PATH/file.jks -alias YourAlias -storepass *** -keypass ***

In order to use our API’s, follow this guide to
generate a vendor token.

Usages

Wrap your app with FronteggProvider

NOTE: we recommend to use FronteggWrapper component along with the NavigationContainer from @react-navigation/native:
to install @react-navigation/native and @react-navigation/native-stack run the following command:

NPM:

npm install -s @react-navigation/native @react-navigation/native-stack react-native-screens react-native-safe-area-context

Yarn:

yarn add @react-navigation/native @react-navigation/native-stack react-native-screens react-native-safe-area-context

Modify your App.tsx file and wrap your app with FronteggProvider and pass your Frontegg configuration:

import * as React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createNativeStackNavigator } from '@react-navigation/native-stack';
import HomeScreen from './HomeScreen';
import ProfileScreen from './ProfileScreen';
import { FronteggWrapper } from '@frontegg/react-native';

const Stack = createNativeStackNavigator();

export default () => {
  return (
    <FronteggWrapper>
      <NavigationContainer>
        <Stack.Navigator>
          <Stack.Screen name="Home" component={HomeScreen} />
          <Stack.Screen name="Profile" component={ProfileScreen} />
        </Stack.Navigator>
      </NavigationContainer>
    </FronteggWrapper>
  );
};

Login with frontegg

To log in with frontegg you can use the useAuth hook:

import { View, Button } from 'react-native';
import { useAuth } from '@frontegg/react-native';


export function MyScreen() {
  const { isAuthenticated, login, logout } = useAuth();
  
  return <View>
    <Button title={'Login'} onPress={login} />
  </View>
} 

Switch tenant frontegg

To switch tenant, get switchTenant from the useAuth hook:

import { useCallback } from 'react';
import { View, Button } from 'react-native';
import { useAuth } from '@frontegg/react-native';


export function MyScreen() {
  const { switchTenant, user } = useAuth();
  
  // user avaiable tenants from user.tenants
  console.log("user tenants", user?.tenants)

  const handleSwitchTenant = useCallback(() => {
    const tenantId = 'TENANT_ID'; // get tenant id from your app state
    

    switchTenant(tenantId).then(() => {
      console.log('Tenant switched successfully');
    }).catch((error) => {
      console.log('Failed to switch tenant', error);
    });
  }, [ switchTenant ]);

  return <View>
    <Button title={'Switch Tenant'} onPress={handleSwitchTenant} />
  </View>;
}

Check if user is authenticated

To check if user is authenticated before display your app you can use the useAuth hook
along with the isLoading property:

import { StyleSheet, View, Text, Button } from 'react-native';
import { useAuth } from '@frontegg/react-native';

export default function HomeScreen() {
  const {
    showLoader,
    isLoading,
    isAuthenticated,
    user,
  } = useAuth();

  // showLoader when the SDK is initializing the app / authenticate the user
  if(showLoader || isLoading) {
    return <View>
      <Text>Loading...</Text>
    </View>
  }

  
  return <View>
    <Text>{isAuthenticated ? 'Authenticated' : 'Not authenticated'}</Text>
    
    {isAuthenticated && <Text>{user?.email}</Text>}

    <Button
        color={isAuthenticated ? '#FF0000' : '#000000'}
        title={isAuthenticated ? 'Logout' : 'Login'}
        onPress={() => {
          isAuthenticated ? logout() : login();
        }}
    />
  </View>
}
