Subscribe to both route params and queryParams in Angular 2

For Angular 6+

import { combineLatest } from 'rxjs';
import { map } from 'rxjs/operators';

...

combineLatest(this.route.params, this.route.queryParams)
    .pipe(map(results => ({params: results[0].xxx, query: results[1]})))
    .subscribe(results => {
        console.log(results);
    });

Where xxx is from your route

{path: 'post/:xxx', component: MyComponent},

I managed to get a single subscription to both the queryParams and Params by combining the observables by using Observable.combineLatest before subscribing.

Eg.

var obsComb = Observable.combineLatest(this.route.params, this.route.queryParams, 
  (params, qparams) => ({ params, qparams }));

obsComb.subscribe( ap => {
  console.log(ap.params['type']);
  console.log(ap.qparams['page']);
});

Late answer, but another solution : Instead of subscribing to the params and queryparams I subscribe to the NavigationEnd event on the router. Fires only once and both params and queryparams are available on snapshot : (example for angular 4)

this.router.events.filter(event=>event instanceof NavigationEnd)
   .subscribe(event=>{
       let yourparameter = this.activatedroute.snapshot.params.yourparameter;
       let yourqueryparameter = this.activatedroute.snapshot.queryParams.yourqueryparameter;
   });

Regarding unsubscribing : yes it is true routing params, queryParams or navigation events subscriptions are automatically unsubscribed by the router, there is however one exception : if your route has children , when navigating between children, no unsubscribe will occur. Only when you navigate away from the parent route!

E.g. I had a situation with tabs as child routes. In constructor of first tab component subscribing on route params to retrieve data. Each time I navigate from first to second tab and back another subscription was added resulting in multiplying the number of requests.
