How to fetch data every 10 minutes in ionic 3 my code is below here..

this.auth.getStudentData(item.username).then(
  data => {

If you want to fetch data every 10 mins you can use rxjs to help you here with an Observable that polls every 10secs.

getStudentStatus() {
let item = JSON.parse(localStorage.getItem('username'))
let poll$ = Observable.interval(10000);

poll$.subscribe(() => this.auth.getStudentData(your logic));
)
