How to keep query string parameters in URL when accessing a route of an Angular 2 app?

Question

I have an Angular 2 test app running the latest alpha (37). There are just three routes, that look like this:

@RouteConfig([
  { path: \'/\', component: Home

Updating for Angular 2:
To preserve query parameters present in the current url, add

// import NavigationExtras 
import  { NavigationExtras } from '@angular/router';

// Set our navigation extras object
// that contains our global query params

let navigationExtras: NavigationExtras = {
      preserveQueryParams: true
    };   

// Navigate to the login page with extras
this.router.navigate(['/someLink'], navigationExtras);
