Property 'cordova' does not exist on type 'Window'. : ionic

Question

In my code, I'm getting the error as Property 'cordova' does not exist on type 'Window'. This is where I'm getting the error var browserRef = window.cordova.InAppBrowser.open()

I've also installed the typings but still I'm getting this error. How can I resolve this?

That's just Typescript complaining because cordova is not part of the window object definition. There're several ways to avoid that error:

One way is to declare a window property of type any, like this:

import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';

declare let window: any; // <--- Declare it like this

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

  constructor(public navCtrl: NavController, ...) { }

  public yourMethod(): void {
    var browserRef = window.cordova.InAppBrowser.open(); // <--- and use it like this
  }

}

Another way would be to cast the window object to be of type any in the same statament:

public anotherMethod(): void {
  var browserRef = (<any>window).cordova.InAppBrowser.open();
}
