Call a function every 10 seconds Angular2

Better use observables

this.sub = Observable.interval(10000)    .subscribe((val) => { console.log('called'); });

to stop it use

this.sub.unsubscribe();

Make sure to import interval with

import 'rxjs/add/observable/interval';

from RxJS 6+ you just use interval.

import { interval } from 'rxjs';//in 10 seconds do somethinginterval(10000).subscribe(x => {    this.myFunctionThatDoesStuff();});

you can use Subscription with the interval.

import { interval, Subscription} from 'rxjs';export class intervalDemo{    mySubscription: Subscription    constructor(){    this.mySubscription= interval(5000).subscribe((x =>{                this.doStuff();            }));    }    doStuff(){        //doing stuff with unsubscribe at end to only run once        this.failedRequestSub.unsubscribe();    }}

A better solution than setTimeout in an Angular app could be to use Observable. Observable have a method named timer that you can use this way (and there is a TimerObservable too but I never used it so I don't know if this is the same thing):

timer = Observable.timer(initialDelay, period);timer.subscribe(tick => {   // Your API call, which will be performed every period});

I encourage you to use RxJS and Observable for your requests too, instead of promises, it seams more the Angular way to do things to me, and RxJS is a really powerful library.
