Typescript instanceof - Cannot find name

Question

I have a problem with Typescript compilation. This code returns the error:

error TS2304: Cannot find name 'NavigationEnd'.

How can I make the compiler know about NavigationEnd type? NavigationEnd is angular2 router event type.

this.router.events.subscribe((e) => {e instanceof NavigationEnd ? 
console.log('NavigationEnd'):console.log('Not NavigationEnd')});

I`m using IDE PHPStorm.

Seems you're missing an import

import { Router, NavigationEnd } from '@angular/router'
