Alert Banner

A prominent notification component for displaying important information or system status messages. Alert banners span the full width of their container and use distinctive colors to indicate message severity.

import {AlertBanner} from "@qualcomm-ui/react/alert-banner"

Examples

Simple

Use the simple API to create a banner using minimal markup.

Heading
Description
<AlertBanner
  action={
    <Button emphasis="white-persistent" size="sm" variant="outline">
      Action
    </Button>
  }
  description="Description"
  dismissable
  heading="Heading"
  onClose={() => console.log("close")}
/>

Composite

The composite API provides individual sub-components for custom layouts or when you need to render custom content within each slot.

Heading
Description
<AlertBanner.Root onClose={() => console.log("close")}>
  <AlertBanner.Icon />
  <AlertBanner.Heading>Heading</AlertBanner.Heading>
  <AlertBanner.Description>Description</AlertBanner.Description>
  <AlertBanner.ActionContainer>
    <Button emphasis="white-persistent" size="sm" variant="outline">
      Action
    </Button>
  </AlertBanner.ActionContainer>
  <AlertBanner.CloseButton />
</AlertBanner.Root>

Emphasis

The emphasis prop controls the banner's color scheme. The default is info. Each emphasis also determines the default icon.

info
success
warning
neutral
<AlertBanner emphasis="info" heading="info" />
<AlertBanner emphasis="success" heading="success" />
<AlertBanner emphasis="warning" heading="warning" />
<AlertBanner emphasis="danger" heading="danger" />
<AlertBanner emphasis="neutral" heading="neutral" />

Variant

The variant prop controls visual prominence. The default strong variant uses solid backgrounds for high visibility. The subtle variant uses muted backgrounds with borders.

info
success
warning
neutral
<AlertBanner emphasis="info" heading="info" variant="subtle" />
<AlertBanner emphasis="success" heading="success" variant="subtle" />
<AlertBanner emphasis="warning" heading="warning" variant="subtle" />
<AlertBanner emphasis="danger" heading="danger" variant="subtle" />
<AlertBanner emphasis="neutral" heading="neutral" variant="subtle" />

Dismissable

The banner is a controlled component. Set dismissable to render a close button, then handle visibility state via the onClose callback. With the composite API, use <AlertBanner.CloseButton />.

Simple API
Composite API
{simpleVisible && (
  <AlertBanner
    closeButtonAriaLabel="Close this banner"
    dismissable
    heading="Simple API"
    onClose={() => setSimpleVisible(false)}
  />
)}

{compositeVisible && (
  <AlertBanner.Root
    closeButtonAriaLabel="Close this banner"
    onClose={() => setCompositeVisible(false)}
    variant="subtle"
  >
    <AlertBanner.Icon />
    <AlertBanner.Heading>Composite API</AlertBanner.Heading>
    <AlertBanner.CloseButton />
  </AlertBanner.Root>
)}

Action

Pass a button to the action prop. Use size="sm" with emphasis="white-persistent" for strong banners, or emphasis="neutral" for subtle banners.

Strong
Use white-persistent emphasis for strong variant
Subtle
Use neutral emphasis for subtle variant
<AlertBanner
  action={
    <Button emphasis="white-persistent" size="sm" variant="outline">
      Take action
    </Button>
  }
  description="Use white-persistent emphasis for strong variant"
  heading="Strong"
  variant="strong"
/>

<AlertBanner
  action={
    <Button emphasis="neutral" size="sm" variant="outline">
      Take action
    </Button>
  }
  description="Use neutral emphasis for subtle variant"
  heading="Subtle"
  variant="subtle"
/>
