Use #oauth2 login with React-Native
Common OAuth2 providers
Can be handled by react-native-app-auth by redirecting to url com.yourapp://oauth2provider.
Example for #Google
import { authorize } from 'react-native-app-auth';const GOOGLE_OAUTH_CLIENT = '...';// ...const authState = await authorize({ issuer: 'https://accounts.google.com', clientId: `${GOOGLE_OAUTH_CLIENT}.apps.googleusercontent.com`, redirectUrl: `com.yourapp:/oauth2redirect/google`, scopes: ['openid', 'profile'], dangerouslyAllowInsecureHttpRequests: true,});Example for #Yandex
const YANDEX_OAUTH_CLIENT = '...';const YANDEX_OAUTH_SECRET = '...'; // better hide it somehowconst APP_ID = 'com.yourapp';const authState = await authorize({ serviceConfiguration: { authorizationEndpoint: `https://oauth.yandex.ru/authorize?response_type=code&client_id=${YANDEX_OAUTH_CLIENT}&redirect_uri=${APP_ID}:/oauth2redirect`, // TODO: replace it with your own backend to secure client_secret: tokenEndpoint: `https://oauth.yandex.ru/token?grant_type=authorization_code&client_id=${YANDEX_OAUTH_CLIENT}&client_secret=${YANDEX_OAUTH_SECRET}`, }, clientId: YANDEX_OAUTH_CLIENT, redirectUrl: `${APP_ID}:/oauth2redirect`, scopes: ['login:info', 'login:avatar'], dangerouslyAllowInsecureHttpRequests: true,});callback(authState.accessToken);Apple ID login
