Import#

Chakra UI exports 4 alert related components.

Alert: The wrapper for alert components.
AlertIcon: The visual icon for the alert that changes based on the status prop.
AlertTitle: The title of the alert to be announced by screen readers.
AlertDescription: The description of the alert to be announced by screen readers.

import {
  Alert,
  AlertIcon,
  AlertTitle,
  AlertDescription,
} from '@chakra-ui/react';

Usage#

<Alert status="error">
  <AlertIcon />
  <AlertTitle>Your browser is outdated!</AlertTitle>
  <AlertDescription>Your Chakra experience may be degraded.</AlertDescription>
</Alert>

Status#

Change the status of the alerts by passing the status prop. This affects the color scheme and icon used. Alert supports error, success, warning, and info statuses.

<Stack spacing={3}>
  <Alert status="error">
    <AlertIcon />
    There was an error processing your request
  </Alert>

  <Alert status="success">
    <AlertIcon />
    Data uploaded to the server. Fire on!
  </Alert>

  <Alert status="warning">
    <AlertIcon />
    Seems your account is about expire, upgrade now
  </Alert>

  <Alert status="info">
    <AlertIcon />
    Chakra is going live on August 30th. Get ready!
  </Alert>
</Stack>

Variant#

Alert has 4 variant styles you can use. Pass the variant prop and use either subtle, solid, left-accent or top-accent.

<Stack spacing={3}>
  <Alert status="success" variant="subtle">
    <AlertIcon />
    Data uploaded to the server. Fire on!
  </Alert>

  <Alert status="success" variant="solid">
    <AlertIcon />
    Data uploaded to the server. Fire on!
  </Alert>

  <Alert status="success" variant="left-accent">
    <AlertIcon />
    Data uploaded to the server. Fire on!
  </Alert>

  <Alert status="success" variant="top-accent">
    <AlertIcon />
    Data uploaded to the server. Fire on!
  </Alert>
</Stack>

Composition#

Alert ships with smaller components to allow for flexibility in creating all kinds of layouts. Here's an example of a custom alert style and layout:

<Alert
  status="success"
  variant="subtle"
  flexDirection="column"
  alignItems="center"
  justifyContent="center"
  textAlign="center"
  height="200px"
>
  <AlertIcon boxSize="40px" mr={0} />
  <AlertTitle mt={4} mb={1} fontSize="lg">
    Application submitted!
  </AlertTitle>
  <AlertDescription maxWidth="sm">
    Thanks for submitting your application. Our team will get back to you soon.
  </AlertDescription>
</Alert>

Alert can also incorporate other Chakra components. Here's an example of an alert with wrapping description text and the CloseButton component with simple close functionality:

function CompExample() {
  const {
    isOpen: isVisible,
    onClose,
    onOpen,
  } = useDisclosure({ defaultIsOpen: true });

  return isVisible ? (
    <Alert status="success">
      <AlertIcon />
      <Box>
        <AlertTitle>Success!</AlertTitle>
        <AlertDescription>
          Your application has been received. We will review your application
          and respond within the next 48 hours.
        </AlertDescription>
      </Box>
      <CloseButton
        alignSelf="flex-start"
        position="relative"
        right={-1}
        top={-1}
        onClick={onClose}
      />
    </Alert>
  ) : (
    <Button onClick={onOpen}>Show Alert</Button>
  );
}
