Controlled count

A badge sample using react hooks to set the number of events.

Events

import { useState } from "react";


export default function Demo() {
  const [count, setCount] = useState(1);
  const addCount = () => setCount(count * 2);


  return (
    <>
      <HvButton onClick={addCount}>Double Value</HvButton>
      <HvBadge showCount count={count} text="Events" textVariant="title4" />
    </>
  );
}

import { useState } from "react";

export default function Demo() {
  const [count, setCount] = useState(1);
  const addCount = () => setCount(count * 2);

  return (
    <>
      <HvButton onClick={addCount}>Double Value</HvButton>
      <HvBadge showCount count={count} text="Events" textVariant="title4" />
    </>
  );
}

Accessibility

If you want to specify a custom aria-label, use the role prop.

Events

<HvBadge
  showCount
  count={25}
  text="Events"
  textVariant="title4"
  role="status"
  aria-label="25 unread notifications"
/>

<HvBadge
  showCount
  count={25}
  text="Events"
  textVariant="title4"
  role="status"
  aria-label="25 unread notifications"
/>
