React-Native-Apple-Authentication

React-Native-Apple-Authentication is a package that allows you to easily integrate Apple's Sign-in with Apple functionality into your React Native app. This package provides you with an interface to the native APIs, so you can authenticate your users without having to navigate away from your app.

Installation

To install React-Native-Apple-Authentication in your React Native project, run the following command:

npm install react-native-apple-authentication

You will also need to configure your Xcode project to allow for Sign-in with Apple. For more information on this, you can refer to the Apple documentation.

Usage

1. Import the package into your component:

import AppleAuthentication from 'react-native-apple-authentication';

2. Call the AppleAuthentication.requestAsync() method to initiate the authentication flow:

const response = await AppleAuthentication.requestAsync({
  requestedScopes: [AppleAuthentication.Scope.FULL_NAME, AppleAuthentication.Scope.EMAIL],
});

This method will display the Apple login page to the user. If the user successfully logs in, this method will return an object containing the user's full name, email, and an authorization code, which you can use to authenticate the user with your backend server.

3. Use the response to authenticate the user:

const {fullName, email, identityToken, authorizationCode} = response;

You can then send this information to your backend server to log the user in.

Example

Here is an example of how you can use React-Native-Apple-Authentication in your app:

import React, {useState} from 'react';
import {View, Text, TouchableOpacity, Alert} from 'react-native';
import AppleAuthentication from 'react-native-apple-authentication';

const App = () => {
  const [user, setUser] = useState(null);

  const handleLogin = async () => {
    try {
      const response = await AppleAuthentication.requestAsync({
        requestedScopes: [
          AppleAuthentication.Scope.FULL_NAME,
          AppleAuthentication.Scope.EMAIL,
        ],
      });

      if (response) {
        const {fullName, email, identityToken, authorizationCode} = response;

        // Send this information to your backend server to log the user in

        setUser({
          fullName: fullName,
          email: email,
        });
      }
    } catch (error) {
      Alert.alert('Error', error.message);
    }
  };

  return (
    <View style={{flex: 1, justifyContent: 'center', alignItems: 'center'}}>
      {user ? (
        <Text>Welcome {user.fullName}!</Text>
      ) : (
        <TouchableOpacity onPress={handleLogin}>
          <Text>Login with Apple</Text>
        </TouchableOpacity>
      )}
    </View>
  );
};

export default App;
