Alert displays a short and concise message to draw a users' attention without interrupting their current task.

Examples

Tones

The component offers several levels of tonal severity.

<Stack gap="large">
  <Alert tone="caution" heading="This is a caution alert">
    Caution message
  </Alert>
  <Alert tone="positive" heading="This is a positive alert">
    Positive message
  </Alert>
  <Alert tone="info" heading="This is an info alert">
    Info message
  </Alert>
  <Alert tone="critical" heading="This is a critical alert">
    Critical message
  </Alert>
</Stack>

Closing

You can also set an onClose prop callback function which will render a close icon button on the alert. The callback function will be called upon the button being pressed.

const [isOpen, setIsOpen] = React.useState(true);

React.useEffect(() => {
  const timeout = setTimeout(() => {
    if (!isOpen) {
      setIsOpen(true);
    }
  }, 2000);

  return () => clearTimeout(timeout);
}, [isOpen]);

if (!isOpen) {
  return null;
}

return (
  <Alert
    tone="caution"
    heading="This is a caution alert"
    onClose={() => setIsOpen(false)}
  >
    Click the button on the right to dismiss this notification
  </Alert>
);

Custom icons

In rare cases, you may need to provide a custom icon. To do so, we expose an icon prop. You can pass it any icon from the Icon package.

<Alert heading="This an info alert" icon={LightBulbIcon}>
  Did you know that Alert components can have custom icons?
</Alert>
