【Angular】NavigationEndで画面遷移後に処理を実行する方法

import { Component, OnInit } from '@angular/core';
import { Router, NavigationEnd } from '@angular/router';
import { filter } from 'rxjs/operators';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
})
export class AppComponent implements OnInit {
  constructor(private router: Router) {}

  ngOnInit(): void {
    this.router.events
      .pipe(
        filter(event => event instanceof NavigationEnd)
      )
      .subscribe((event: NavigationEnd) => {
        console.log('遷移後のURL:', event.urlAfterRedirects);

        // 遷移後に実行したい処理をここに書く
        this.scrollToTop();
      });
  }

  private scrollToTop(): void {
    window.scrollTo({ top: 0, behavior: 'smooth' });
  }
}
