  .signIn()
  .then(GoogleUser => {
    // on success do something
    console.log('GoogleUser', GoogleUser)
    console.log('getId', GoogleUser.getId())
    console.log('getBasicProfile', GoogleUser.getBasicProfile())
    console.log('getAuthResponse', GoogleUser.getAuthResponse())
  })
  .catch(error => {
    console.log('error', error)
  })
}

Facebook App ID Setup

Important: The Facebook SDK must first be loaded asynchronously for the plugin to work. Something like this will do:

export const initFbsdk = () => {
    return new Promise(resolve => {
        window.fbAsyncInit = function() {
            FB.init({
                appId      : 'xxxxxxxxxxxxxxxxxxx',
                cookie     : true,  // enable cookies to allow the server to access the session
                xfbml      : true,  // parse social plugins on this page
                version    : 'v2.8' // use graph api version 2.8
            });
        };
        (function(d, s, id) {
            var js, fjs = d.getElementsByTagName(s)[0];
            if (d.getElementById(id)) return;
            js = d.createElement(s); js.id = id;
            js.src = "//connect.facebook.net/en_US/sdk.js";
            fjs.parentNode.insertBefore(js, fjs);
        }(document, 'script', 'facebook-jssdk'));
    })
}

If you're not in a modular environment, just include it as a <code> <script>``</code>.

Usage

Step 1: import and use the plugin if you're in a modular environment otherwise plugin will register itself.

import { initFbsdk } from '@/config/facebook_oAuth.js'

Step 2: Initialize the Facebook instance with the app id

mounted () {
   initFbsdk()
}

Step 3: Add the button click event

loginWithFacebook () {
  window.FB.login(response => {
    console.log('fb response', response)
  }, this.params)
}
