  }
 
}
 
//same with:
//hello.init({facebook: '<your-app-id>'}, {scope: 'friends, email'});

And call in component:

constructor(private _ngxHellojsService: NgxHellojsService) {
}

Login

<!-- Using directive -->
<p ngxLoginHellojs="facebook"
   (successEvent)="loginSuccessfullyAction($event)"
   (errorEvent)="loginFailedAction($event)">Login facebook</p>

this._ngxHellojsService
    .login('facebook', {scope: 'friends, photos, publish'})
    .subscribe(data => {}, error => {});
 
//same with:
//hello('facebook').login({scope: 'friends, photos, publish'})

<p ngxLogoutHellojs="facebook"
   (successEvent)="logoutSuccessfullyAction($event)"
   (errorEvent)="logoutFailedAction($event)">Logout</p>

this._ngxHellojsService.logout('facebook')
                       .subscribe(data => {}, error => {});
 
//same with:
//hello('facebook').logout()
//                 .then(function(data) {}, function(error) {});

Get auth response

const fbResult = this._ngxHellojsService.getAuthResponse('facebook');
 
//same with:
//var fbResult = hello('facebook').getAuthResponse();

this._ngxHellojsService.api('facebook', 'me')
                       .subscribe(data => {}, error => {});
 
//same with:
//hello('facebook').api('me')
//                 .then(function(data) {}, function(error) {});

this._ngxHellojsService.api('facebook', 'me/friends', null, {limit: 1})
                       .subscribe(data => {}, error => {});
 
//same with:
//hello('facebook').api('me/friends', {limit: 1})
//                 .then(function(data) {}, function(error) {});

On / Off

messageAfterLogin = () => {
    console.log('Login successfully');
}
 
this._ngxHellojsService.on('auth.login', this.messageAfterLogin);
this._ngxHellojsService.off('auth.login', this.messageAfterLogin);
 
//same with:
//var messageAfterLogin = function () {
//  console.log('Login successfully');
//};
//
//hello.on('auth.login', messageAfterLogin);
//hello.off('auth.login', messageAfterLogin);
