How to implement SignIn with Google in Angular 2 using Typescript

Question

I have been trying to implement sign in with Google in angular 2 in a separate login component. I am unable to implement it with the documentation available in Google https:

Answer 1

There is also another way to connect with google :

Add theses lines in the index.html :

and then here is a sample code to write on a component (or a service if you want) :

import {Component} from "@angular/core";
declare const gapi : any;


@Component({ ... })
export class ComponentClass {
   constructor() {
      gapi.load('auth2', function () {
         gapi.auth2.init()
      });
   }

   googleLogin() {
      let googleAuth = gapi.auth2.getAuthInstance();
      googleAuth.then(() => {
         googleAuth.signIn({scope: 'profile email'}).then(googleUser => {
            console.log(googleUser.getBasicProfile());
         });
      });
   }
}
