Description

The following example shows how to construct a component using information from a currently activated route.

import {Component} from '@angular/core';
/* . . . */
import {ActivatedRoute} from '@angular/router';
import {Observable} from 'rxjs';
import {map} from 'rxjs/operators';
/* . . . */

@Component({
/* . . . */
})
export class ActivatedRouteComponent {
  constructor(route: ActivatedRoute) {
    const id: Observable<string> = route.params.pipe(map(p => p.id));
    const url: Observable<string> = route.url.pipe(map(segments => segments.join('')));
    // route.data includes both `data` and `resolve`
    const user = route.data.pipe(map(d => d.user));
  }
}
