Counter with Auto-Increment — Qwik Code
Automatically increments the counter every second using Qwik signals and useTask$.
import { component$, useStore, useTask$ } from '@builder.io/qwik';
export const AutoCounter = component$(() => {
const state = useStore({ count: 0 });
useTask$(({ track }) => {
track(() => state.count);
const interval = setInterval(() => state.count++, 1000);
return () => clearInterval(interval);
});
return <h2>Counter: {state.count}</h2>;
