Web Facebook login using angular 4 : Window not defined in script – Facebook api

I am trying to use javascript SDK for facebook login,
I am using the below script with angular 4,
but I am getting an error saying that window is not defined?
Could you please help me integrate Facebook graph API using angular 4?

<!DOCTYPE html>

<title>Facebook Login JavaScript Example</title>

<body>
<script>
// This is called with the results from from FB.getLoginStatus().
function statusChangeCallback(response) {
console.log('statusChangeCallback');
console.log(response);
// The response object is returned with a status field that lets the
// app know the current login status of the person.
// Full docs on the response object can be found in the documentation
// for FB.getLoginStatus().
if (response.status === 'connected') {
  // Logged into your app and Facebook.
  testAPI();
} else {
  // The person is not logged into your app or we are unable to tell.
  document.getElementById('status').innerHTML = 'Please log ' +
    'into this app.';
}
}

 // This function is called when someone finishes with the Login
 // Button.  See the onlogin handler attached to it in the sample
// code below.
function checkLoginState() {
FB.getLoginStatus(function(response) {
  statusChangeCallback(response);
});
}

window.fbAsyncInit = function() {
 FB.init({
  appId      : '{your-app-id}',
  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
});

// Now that we've initialized the JavaScript SDK, we call
// FB.getLoginStatus().  This function gets the state of the
// person visiting this page and can return one of three states to
// the callback you provide.  They can be:
//
// 1. Logged into your app ('connected')
// 2. Logged into Facebook, but not your app ('not_authorized')
// 3. Not logged into Facebook and can't tell if they are logged into
//    your app or not.
//
// These three cases are handled in the callback function.

FB.getLoginStatus(function(response) {
  statusChangeCallback(response);
 });

 };

// Load the SDK asynchronously
(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'));

// Here we run a very simple test of the Graph API after login is
// successful.  See statusChangeCallback() for when this call is made.
function testAPI() {
  console.log('Welcome!  Fetching your information.... ');
  FB.api('/me', function(response) {
  console.log('Successful login for: ' + response.name);
  document.getElementById('status').innerHTML =
    'Thanks for logging in, ' + response.name + '!';
 });
}
</script>

<!--
Below we include the Login Button social plugin. This button uses
the JavaScript SDK to present a graphical Login button that triggers
the FB.login() function when clicked.
 -->

 <fb:login-button scope="public_profile,email" 
onlogin="checkLoginState();">
</fb:login-button>

 <div id="status">
</div>

</body>

    I think for facebook integration you can use the npm module “angular4-oauth-login” instead of graph api.

    The above plugin give you the integration for google as well.
    I have tried the above module and found very easy to understand and implement.

    Hope this will help for you. Thanks !!

    The simplest way to avoid error window is not defined is using inline definition:

    (<any>window).fbAsyncInit = function() {

    Other way is definitions like this:

    declare var window: any;
declare var FB: any;
