How can I use facebook login with Create-react-native-app

Question

I try to find a way to use Facebook login with Create-react-native-app for both Android and IOS. Is that possible? All this seem pretty new...

Answer 1

Use the Expo SDK. This way you won't have to eject from create-react-native-app.

import { Facebook } from 'expo';

async function logIn() {
  const { type, token } = await Facebook.logInWithReadPermissionsAsync('<APP_ID>', {
    permissions: ['public_profile'],
  });

  if (type === 'success') {
    // Get the user's name using Facebook's Graph API
    const response = await fetch(`https://graph.facebook.com/me?access_token=${token}`);

    Alert.alert(
      'Logged in!',
      `Hi ${(await response.json()).name}!`,
    );
  }
}
