Determine whether there was a transition or page refresh?

Question

Angular

Hello. Don't tell me?
ngx-translate is used to change the language. When there is a normal transition to the SPA, then everything works fine only once the getConditions methods . But when the page is refreshed. then the translateService.onLangChange subscription is already triggered .

ngOnInit() {
    this.getConditions();

    this.subscription.add(
      this.translateService.onLangChange.subscribe(() => this.getConditions())
    );
  }

How can this be bypassed? Whether it is possible to define somehow that there was a transition to the page in SPA or its updating on F5? Thank you.
