Alert

import { InfoIcon } from "@phosphor-icons/react"
import { Alert, AlertDescription, AlertTitle } from "@/components/ui/alert"

export default function AlertDemo() {
  return (
    <div className="w-96">
      <Alert>
        <InfoIcon />
        <AlertTitle>Update available</AlertTitle>
        <AlertDescription>
          A new version is ready to install. Restart the app to apply it.
        </AlertDescription>
      </Alert>
    </div>
  )
}

An Alert is a rounded container with an optional leading icon, an AlertTitle, an optional AlertDescription and an optional AlertAction. Place the icon as a direct child; the layout switches to a two-column grid so the title and description align beside it.

Use an alert for inline, persistent messages such as updates, warnings or errors. To interrupt the user and require a decision, use Alert Dialog instead; for short-lived notifications, use Toast.

Installation

CLI

$ pnpm dlx shadcn@latest add @esuiss/alert

Works in any project with a components.json. See Installation for the one-line registry setup. Or use the suiss/ui CLI:

$ pnpm dlx @esuiss/ui@latest add alert

Manual

Install the dependencies and add the cn helper:

$ pnpm add class-variance-authority

Copy the source into components/ui/alert.tsx:

components/ui/alert.tsx

import { cva, type VariantProps } from "class-variance-authority"
import type * as React from "react"
import { cn } from "@/lib/utils"

const alertVariants = cva(
  "group/alert relative grid w-full gap-0.5 rounded-2xl p-5 text-start text-base has-data-[slot=alert-action]:pe-24 has-[>svg]:grid-cols-[auto_1fr] has-[>svg]:gap-x-3 has-data-[slot=alert-description]:*:[svg]:row-span-2 *:[svg]:translate-y-px *:[svg:not([class*='size-'])]:size-5",
  {
    variants: {
      variant: {
        default: "bg-muted text-foreground *:[svg]:text-primary",
        destructive: "bg-muted text-foreground *:[svg]:text-destructive",
      },
    },
    defaultVariants: {
      variant: "default",
    },

Update the import paths to match your project.

Usage

import { Alert, AlertTitle, AlertDescription, AlertAction } from "@/components/ui/alert"

<div className="w-96">
  <Alert>
    <InfoIcon weight="fill" />
    <AlertTitle>Update available</AlertTitle>
    <AlertDescription>
      A new version is ready to install. Restart the app to apply it.
    </AlertDescription>
  </Alert>
</div>

Put an icon from your icon library (or any svg) first inside Alert; it is sized to size-5 unless it already has a size class. When AlertDescription is present the icon spans both rows.

AlertAction is positioned in the top-end corner, and the alert reserves end padding for it automatically.

Examples

Destructive

Tints the icon with the destructive color for errors.

import { WarningCircleIcon } from "@phosphor-icons/react"
import { Alert, AlertDescription, AlertTitle } from "@/components/ui/alert"

export default function AlertDestructive() {
  return (
    <div className="w-96">
      <Alert variant="destructive">
        <WarningCircleIcon />
        <AlertTitle>Payment failed</AlertTitle>
        <AlertDescription>
          Your card was declined. Update your billing details to continue.
        </AlertDescription>
      </Alert>
    </div>
  )
}

Without icon

A title and description with no leading icon.

import { Alert, AlertDescription, AlertTitle } from "@/components/ui/alert"

export default function AlertWithoutIcon() {
  return (
    <div className="w-96">
      <Alert>
        <AlertTitle>Scheduled maintenance</AlertTitle>
        <AlertDescription>
          The service will be unavailable on Sunday from 2:00 to 4:00 AM.
        </AlertDescription>
      </Alert>
    </div>
  )
}

Title only

An icon with a single line of text and no description.

import { InfoIcon } from "@phosphor-icons/react"
import { Alert, AlertTitle } from "@/components/ui/alert"

export default function AlertTitleOnly() {
  return (
    <div className="w-96">
      <Alert>
        <InfoIcon />
        <AlertTitle>Your changes have been saved.</AlertTitle>
      </Alert>
    </div>
  )
}

With action

Places a small button in the top-end corner with AlertAction.

import { InfoIcon } from "@phosphor-icons/react"
import {
  Alert,
  AlertAction,
  AlertDescription,
  AlertTitle,
} from "@/components/ui/alert"
import { Button } from "@/components/ui/button"

export default function AlertWithAction() {
  return (
    <div className="w-96">
      <Alert>
        <InfoIcon />
        <AlertTitle>Storage almost full</AlertTitle>
        <AlertDescription>
          You have used 90% of your storage. Upgrade for more space.
        </AlertDescription>
        <AlertAction>
          <Button size="xs">Upgrade</Button>
        </AlertAction>
      </Alert>
    </div>
  )
}

API Reference

Anatomy4 parts

<Alert>

</Alert>

Alert

The container that lays out the icon, text and action.

Prop	Type	Default	Description
`variant`	`"default" \| "destructive"`	`"default"`	Icon color. `default` uses `text-primary`; `destructive` uses `text-destructive`.

Also accepts the props of React.ComponentProps<"div">.

AlertTitle

The bold headline of the message.

Also accepts the props of React.ComponentProps<"div">.

AlertDescription

Secondary text that explains the message.

Also accepts the props of React.ComponentProps<"div">.

AlertAction

An absolutely positioned slot for a button or link in the top-end corner.

Also accepts the props of React.ComponentProps<"div">.

Accessibility

Alert renders with role="alert", so assistive technology announces its content when it appears.
Interactive content in AlertAction stays in the normal tab order.
Decorative icons should not need a label; put the meaning in the title text.

Notes

Styling hooks: data-slot="alert", "alert-title", "alert-description" and "alert-action".
Both variants use bg-muted; they differ only in icon color (text-primary or text-destructive).
Links inside the title or description are underlined automatically.

iOS

import { CheckCircleIcon } from "phosphor-react-native"
import { Alert, AlertDescription, AlertTitle } from "@/components/ui/alert"

export function AlertExample() {
  return (
    <Alert icon={CheckCircleIcon}>
      <AlertTitle>Payment successful</AlertTitle>
      <AlertDescription>
        Your payment of $29.99 has been processed. A receipt has been sent to
        your email.
      </AlertDescription>
    </Alert>
  )
}

import EsuissUI
import PhosphorSwift
import SwiftUI

struct AlertExample: View {
  var body: some View {
    InlineAlert(icon: Ph.checkCircle.regular) {
      AlertTitle("Payment successful")
      AlertDescription("Your payment of $29.99 has been processed. A receipt has been sent to your email.")
    }
  }
}

import androidx.compose.runtime.Composable
import com.adamglin.PhosphorIcons
import com.adamglin.phosphoricons.Regular
import com.adamglin.phosphoricons.regular.CheckCircle
import com.esuiss.ui.components.Alert

    Alert(icon = PhosphorIcons.Regular.CheckCircle) {
        AlertTitle("Payment successful")
        AlertDescription("Your payment of \$29.99 has been processed. A receipt has been sent to your email.")
    }
}

Alert is a View on a rounded bg-muted surface with an optional leading icon, a title and description column, and an optional action pinned to the top-end corner. It is static and stays in the layout; it is not a toast or a modal.

Use the default variant for neutral information, where the icon uses the primary color, and destructive for errors, where the icon uses the destructive color.

Installation

Usage

import { Alert, AlertTitle, AlertDescription, AlertAction } from "@/components/ui/alert"

<Alert icon={CheckCircleIcon}>
  <AlertTitle>Payment successful</AlertTitle>
  <AlertDescription>
    Your payment of $29.99 has been processed. A receipt has been sent to
    your email.
  </AlertDescription>
</Alert>

Pass a Phosphor icon component to icon, and compose AlertTitle and AlertDescription as children. Any AlertAction child is detected and placed in the corner, and extra end padding is added so the text does not run under it.

Use iconClassName to adjust the icon's size or color.

API Reference

Alert

Container with the icon, text column and action.

Prop	Type	Default	Description
`icon`	`PhosphorIcon`	-	Phosphor icon component shown before the text.
`variant`	`"default" \| "destructive"`	`"default"`	`default` or `destructive`; changes the icon color.
`iconClassName`	`string`	-	Extra classes for the icon.

Also accepts the props of React.ComponentProps<typeof View>, React.RefAttributes<View>.

AlertTitle

Bold first line.

Also accepts the props of React.ComponentProps<typeof Text>.

AlertDescription

Secondary-colored supporting text.

Also accepts the props of React.ComponentProps<typeof Text>.

AlertAction

Slot positioned in the top-end corner.

Also accepts the props of React.ComponentProps<typeof View>, React.RefAttributes<View>.

Accessibility

The container has the alert role.
The icon is decorative; put the meaning in the title or description.

Notes

Uses bg-muted, text-foreground, text-primary and text-destructive tokens; light and dark follow the system appearance.
The action is positioned with end-4, so it flips in right-to-left layouts.

import { InfoIcon } from "@phosphor-icons/react"
import { Alert, AlertDescription, AlertTitle } from "@/components/ui/alert"

export default function AlertDemo() {
  return (
    <div className="w-96">
      <Alert>
        <InfoIcon />
        <AlertTitle>Update available</AlertTitle>
        <AlertDescription>
          A new version is ready to install. Restart the app to apply it.
        </AlertDescription>
      </Alert>
    </div>
  )
}

Use an alert for inline, persistent messages such as updates, warnings or errors. To interrupt the user and require a decision, use Alert Dialog instead; for short-lived notifications, use Toast.

Usage

import { Alert, AlertTitle, AlertDescription, AlertAction } from "@/components/ui/alert"

<div className="w-96">
  <Alert>
    <InfoIcon weight="fill" />
    <AlertTitle>Update available</AlertTitle>
    <AlertDescription>
      A new version is ready to install. Restart the app to apply it.
    </AlertDescription>
  </Alert>
</div>

Put an icon from your icon library (or any svg) first inside Alert; it is sized to size-5 unless it already has a size class. When AlertDescription is present the icon spans both rows.

AlertAction is positioned in the top-end corner, and the alert reserves end padding for it automatically.

Examples

Destructive

Tints the icon with the destructive color for errors.

import { WarningCircleIcon } from "@phosphor-icons/react"
import { Alert, AlertDescription, AlertTitle } from "@/components/ui/alert"

export default function AlertDestructive() {
  return (
    <div className="w-96">
      <Alert variant="destructive">
        <WarningCircleIcon />
        <AlertTitle>Payment failed</AlertTitle>
        <AlertDescription>
          Your card was declined. Update your billing details to continue.
        </AlertDescription>
      </Alert>
    </div>
  )
}

Without icon

A title and description with no leading icon.

import { Alert, AlertDescription, AlertTitle } from "@/components/ui/alert"

export default function AlertWithoutIcon() {
  return (
    <div className="w-96">
      <Alert>
        <AlertTitle>Scheduled maintenance</AlertTitle>
        <AlertDescription>
          The service will be unavailable on Sunday from 2:00 to 4:00 AM.
        </AlertDescription>
      </Alert>
    </div>
  )
}

Title only

An icon with a single line of text and no description.

import { InfoIcon } from "@phosphor-icons/react"
import { Alert, AlertTitle } from "@/components/ui/alert"

export default function AlertTitleOnly() {
  return (
    <div className="w-96">
      <Alert>
        <InfoIcon />
        <AlertTitle>Your changes have been saved.</AlertTitle>
      </Alert>
    </div>
  )
}

With action

Places a small button in the top-end corner with AlertAction.

import { InfoIcon } from "@phosphor-icons/react"
import {
  Alert,
  AlertAction,
  AlertDescription,
  AlertTitle,
} from "@/components/ui/alert"
import { Button } from "@/components/ui/button"

export default function AlertWithAction() {
  return (
    <div className="w-96">
      <Alert>
        <InfoIcon />
        <AlertTitle>Storage almost full</AlertTitle>
        <AlertDescription>
          You have used 90% of your storage. Upgrade for more space.
        </AlertDescription>
        <AlertAction>
          <Button size="xs">Upgrade</Button>
        </AlertAction>
      </Alert>
    </div>
  )
}

API Reference

Anatomy4 parts

<Alert>

</Alert>

Alert

The container that lays out the icon, text and action.

Prop	Type	Default	Description
`variant`	`"default" \| "destructive"`	`"default"`	Icon color. `default` uses `text-primary`; `destructive` uses `text-destructive`.

Also accepts the props of React.ComponentProps<"div">.

AlertTitle

The bold headline of the message.

Also accepts the props of React.ComponentProps<"div">.

AlertDescription

Secondary text that explains the message.

Also accepts the props of React.ComponentProps<"div">.

AlertAction

An absolutely positioned slot for a button or link in the top-end corner.

Also accepts the props of React.ComponentProps<"div">.

Accessibility

Alert renders with role="alert", so assistive technology announces its content when it appears.
Interactive content in AlertAction stays in the normal tab order.
Decorative icons should not need a label; put the meaning in the title text.

Notes

Styling hooks: data-slot="alert", "alert-title", "alert-description" and "alert-action".
Both variants use bg-muted; they differ only in icon color (text-primary or text-destructive).
Links inside the title or description are underlined automatically.

iOS

import { CheckCircleIcon } from "phosphor-react-native"
import { Alert, AlertDescription, AlertTitle } from "@/components/ui/alert"

export function AlertExample() {
  return (
    <Alert icon={CheckCircleIcon}>
      <AlertTitle>Payment successful</AlertTitle>
      <AlertDescription>
        Your payment of $29.99 has been processed. A receipt has been sent to
        your email.
      </AlertDescription>
    </Alert>
  )
}

import EsuissUI
import PhosphorSwift
import SwiftUI

struct AlertExample: View {
  var body: some View {
    InlineAlert(icon: Ph.checkCircle.regular) {
      AlertTitle("Payment successful")
      AlertDescription("Your payment of $29.99 has been processed. A receipt has been sent to your email.")
    }
  }
}

import androidx.compose.runtime.Composable
import com.adamglin.PhosphorIcons
import com.adamglin.phosphoricons.Regular
import com.adamglin.phosphoricons.regular.CheckCircle
import com.esuiss.ui.components.Alert

        AlertTitle("Payment successful")
        AlertDescription("Your payment of \$29.99 has been processed. A receipt has been sent to your email.")
    }
}

Use the default variant for neutral information, where the icon uses the primary color, and destructive for errors, where the icon uses the destructive color.

API Reference

Alert

Container with the icon, text column and action.

Prop	Type	Default	Description
`icon`	`PhosphorIcon`	-	Phosphor icon component shown before the text.
`variant`	`"default" \| "destructive"`	`"default"`	`default` or `destructive`; changes the icon color.
`iconClassName`	`string`	-	Extra classes for the icon.

Also accepts the props of React.ComponentProps<typeof View>, React.RefAttributes<View>.

AlertTitle

Bold first line.

Also accepts the props of React.ComponentProps<typeof Text>.

AlertDescription

Secondary-colored supporting text.

Also accepts the props of React.ComponentProps<typeof Text>.

AlertAction

Slot positioned in the top-end corner.

Also accepts the props of React.ComponentProps<typeof View>, React.RefAttributes<View>.

Accessibility

The container has the alert role.
The icon is decorative; put the meaning in the title or description.

Notes

Uses bg-muted, text-foreground, text-primary and text-destructive tokens; light and dark follow the system appearance.
The action is positioned with end-4, so it flips in right-to-left layouts.
