Retrieve hash fragment from url with Angular2

To expand on the current answers, I wanted to address an easy way to parse the query params in the hash (specifically for a federated response) since the ActivatedRoute doesn't seem to handle that natively.

this.route.fragment.subscribe(fragment => {
  const response = _.fromPairs(Array.from(new URLSearchParams(fragment)));
  response.access_token;
  response.id_token;
  response.expires_in;
  response.token_type;
});

First create a new URLSearchParams object with the fragment to query for its values:

new URLSearchParams(fragment).get('access_token');

For most cases this is probably all that is needed, but if converting this to an object is desired, Array.from converts URLSearchParams into an array of arrays that looks like: [['key', 'value'], ...]. Then lodash's _.fromPairs converts this to an object.

For those still looking :

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

export class MyComponent {

  constructor(
    private route: ActivatedRoute,
  ) { }

  myfunction(){
    this.route.fragment.subscribe((fragment: string) => {
        console.log("My hash fragment is here => ", fragment)
    })
  }
}

you can also use ActivatedRouteSnapshot with no need to subscribe for all changes on it.

@Component({templateUrl:'./my-component.html'})
class MyComponent {
  constructor(route: ActivatedRoute) {
    const fragment: string = route.snapshot.fragment;
  }
}
