Sometimes we need to call particular service after interval of time to update data on page so below is solution:

Add below import code in your component.ts file

import { Observable } from “rxjs”;

import { IntervalObservable } from “rxjs/observable/IntervalObservable”;

import { TimerObservable } from “rxjs/observable/TimerObservable”;

import “rxjs/add/operator/takeWhile”;

Declare variable in class
export class MyComponent implements OnInit { 

private alive: boolean; 

}

In ngOnInit() function use below code to call service after particular interval of time
ngOnInit() {

IntervalObservable.create(10000)  .takeWhile(() => this.alive) // only fires when component is alive  .subscribe(() => { this.yourService.getDataList()   .subscribe(data => { this.agentData = data.json().result; console.log(this.agentData);   });  });}

ngOnDestroy(){
    this.alive = false; // switches your TimerObservable off
  }
