1. Using Reazy CLI (only for iOS, Android coming soon)

$ reazy add auth                    // dependency
$ reazy add native-facebook-auth

2. Manual

• Install reazy-auth which is a dependency of this plugin.

• Follow these steps to install react-native-fbsdk.

• Install reazy-native-auth-facebook

$ npm install --save reazy-native-auth-facebook

• Add these lines to your src/app.js

...
import auth from 'reazy-auth';
import authFacebook from 'reazy-native-auth-facebook';   // <-- import the service
...
...
app.use(auth(), 'auth');

reazy-native-auth-facebook uses reazy-auth to store user details and access token.

Usage

This service provides the following:

login(readPermissions, requestFields)

Calls auth.setToken(accessToken) after successful login and auth.setUser(user) after successful fetching of user.

• readPermissions: Array

  List of required permissions

  Example: ['public_profile', 'email']

• requestFields: string

  Fields concatenated with , that you want to fetch in the user object returned from graph API

  Example: 'name, gender, age_range, first_name, last_name, email'

• returns a promise which resolves with this object

  {
    user: user,              // User object returned from Facebook Graph API
    accessToken: accessToken // Access token returned after successful login
  }

  and rejects with the error message.

• Example:

  app.authFacebook.login(['public_profile', 'email'], 'name, email').then((response) => {
    console.log(`Welcome, ${response.user.name}`);
  })

  After this you can also fetch the user object and token from auth service

  const user = app.auth.getUser();  // Assuming that reazy-auth service is registered with name 'auth'
  const accessToken = app.auth.getToken();

logout()

This function logs out the user and calls auth.setToken(null) and auth.setUser(null).

• Example:

  app.authFacebook.logout();

FBSDK

If you want to do more with FBSDK, this will get you the object imported from react-native-fbsdk.

• Example:

  const FBSDK = app.authFacebook.FBSDK;
  const {
    ShareDialog,
    LoginManager,
    ShareApi,
    AppEventsLogger,
  } = FBSDK
