Navigation Service

Overview​

The NavigationService is responsible for handling navigation events and extracting relevant information from the URL.

Observable that emits events of type NavigationEnd from the Angular Router.

Operations:

  • Maps all router events to RouterEvent.
  • Filters the events to only include instances of NavigationEnd.
  • Taps into the event stream to extract the route name from the URL and notify the audit service of route changes, excluding the "loading" route and duplicate navigations.
  • Updates the urlAfterNavigation property with the current URL after navigation.
  • Shares the replayed value with a buffer size of 1 to ensure subscribers receive the latest emitted value.

Type: Observable<RouterEvent>

path$​

An observable that emits the tab extracted from the URL pathname or the last part of the URL.

Operations:

  • Listens to navigation end events and processes the URL to determine the current tab.
  • Creates a fake URL object to extract the pathname.
  • Uses the getQueryParamsFromUrl function to extract the tab from the URL pathname or defaults to the last part of the URL if no tab is found.

Type: Observable<string>

Example​

import { NavigationService } from '@sinequa/atomic-angular';

constructor(private navigationService: NavigationService) {
  this.navigationService.navigationEnd$.subscribe(event => {
    console.log('Navigation ended:', event);
  });

  this.navigationService.path$.subscribe(tab => {
    console.log('Current tab:', tab);
  });
}
