Creating a recurring task in Angular to perform a specific action at regular intervals

I'm working on a new feature using Angular 13 and I need to create an asynchronous function that can update data from my API at specified intervals. Can anyone suggest the most efficient method for accomplishing this task?

Answer №1

Below is an example of code that increases the value every 5 seconds

import { Component, OnInit } from '@angular/core';
import { interval } from 'rxjs';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css'],
})
export class AppComponent implements OnInit {
  value = 0;

  ngOnInit(): void {
    this.incrementValue();
  }

  incrementValue() {
    const timer = interval(5 * 1000); // adjust timer as needed
    timer.subscribe(() => {
      this.value += 1;
      console.log(this.value);
    });
  }
}
