How to Refresh an Angular Component

How to Refresh a Component in Angular

After some research and modifying my code as below, the script worked for me. I just added the condition:

this.router.navigateByUrl('/RefreshComponent', { skipLocationChange: true }).then(() => {
    this.router.navigate(['Your actualComponent']);
}); 

Angular refresh component

You probally dont have RefreshComponent route in you route configuration.

As far as refresing your component goes, just modify your function as follows, you don't need RefreshComponent route.

Replace navigateByUrl('/RefreshComponent',... with navigateByUrl('/',...

changeLocation(locationData) {

    // save current route first
    const currentRoute = this.router.url;

    this.router.navigateByUrl('/', { skipLocationChange: true }).then(() => {
        this.router.navigate([currentRoute]); // navigate to same route
    }); 
}

How to reload a page in Angular 8 the proper way

You can find total working example here in this StackBlitz Link

Update
First of all doing window.location.reload() is totally against of Single-Page-Application nature. rather, You can reload particular component when actually clicking on that link.. so, to do this task we have angular router. For particular component reload you can push this line of code in main app.component.ts once for full application.

mySubscription;

 constructor(private router: Router, private activatedRoute: ActivatedRoute){
    this.router.routeReuseStrategy.shouldReuseRoute = () => false;
    this.mySubscription = this.router.events.subscribe((event) => {
      if (event instanceof NavigationEnd) {
         // Trick the Router into believing it's last link wasn't previously loaded
         this.router.navigated = false;
      }
    }); 
 }

above code we are going to subscribing to router-events. and then we are checking each and every router-NavigationEnd event, then just telling router, forget to add current navigation of router to its own history. So, each time whenever we are trying to reload same component each and every events are firing for that particular component only, thats a SPA.

IN app.component.ts of ngOnDestroy() we have to unsubscribe from router events, when component is destroyed.

ngOnDestroy(){
  if (this.mySubscription) {
    this.mySubscription.unsubscribe();
  }
}

Now, for example you have Home and Details component or anything else of component... You can reload each component by calling this.router.navigate([this.router.url]) this will reload all current component. for example, In home component we have reload-button and click event of that we are just calling this.router.navigate([this.router.url]). same for details component too.. or any other component..

Home.component.ts

reLoad(){
  this.router.navigate([this.router.url])
}

Details.component.ts

reLoad(){
  this.router.navigate([this.router.url])
}

You can check in updated above StackBlitz link, all working example of reloading with full router-state reloading. In browser console see each and every events of component is firing by clicking button reload().

How to auto refresh page/component view in angular

Try this:

ngOnInit(): void {
    this.updateSubscription = timer(0, 120000).pipe(
      switchMap(x => this.httpMarketData.getTableByType('Customer Table'))
    ).subscribe((response: TableData[]) => {
      this.getTableData(response);
    });
}

Explanation:

2. Use switchMap to switch to the http-observable after every delay.
