Ionic2 rc0 How to use @types for third-party libraries

Ionic Framework ionic-v3
1

I installed
npm install --save @types/gapi.auth2

How to import and use it?

don’t open a new thread for the same problem, it just isn’t necessary!

you already asked the same thing here: How to use TypeScript definitions @types in ionic2 project

read http://ionicframework.com/docs/v2/faq/ to get the idea of typings/@types

note: rc0 uses @types see the changelog: https://github.com/driftyco/ionic/blob/master/CHANGELOG.md#typings

all you have done now is installed typeScript definitions for Google API Client, did you install/add the Google API Client library too?

@fishgrind So sorry for duplicating, but I didn’t find solution :frowning:
I have installed
npm install --save @types/gapi

home.html
import { Component } from ‘@angular/core’;

import { NavController } from 'ionic-angular';


@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {

  constructor(public navCtrl: NavController) {

  }

 	test_init(){
	  var auth = gapi.auth2.init({
	    client_id: 'xxxx.googleusercontent.com'
	  });
	}

}

home.html
<button ion-button (click)="test_init()">Test auth</button>

index.htm (add google api client)
<script src="https://apis.google.com/js/api:client.js"></script>

but it has error in console

Cannot read property 'init' of undefined

I want to use Google Drive API, and I need access_token.
If I use Google Plus native, it doesn’t run on browser
