Installation

Important

If you are not using NextUI as your primary UI library in your project, we are not recommending using this package. This package is built on top of NextUI components and requires NextUI to work correctly. However, if you are decided to use NextUI, you can consult the NextUI documentation to get started.

To start using NextuiAlert, install the package using npm or yarn:

npm install nextui-alert

Getting Started

Here's how to get started with NextuiAlert in your project.

Basic Example

You can use the NextuiAlert component by specifying the severity and providing a title:

import NextuiAlert from 'nextui-alert'

function App() {
    return <NextuiAlert>Something went wrong with your request.</NextuiAlert>
}

export default App

Variants and Severity

This component supports multiple variants (flat, bordered, solid) and severities (info, success, warning, danger), allowing you to tailor the alert's appearance:

<NextuiAlert severity="success" variant="solid" title="Success">
    Operation completed successfully!
</NextuiAlert>

<NextuiAlert severity="warning" variant="bordered" title="Warning">
    Proceed with caution!
</NextuiAlert>

Adding Close Functionality

To make the alert dismissible, pass an onClose function. A close button will appear automatically:

<NextuiAlert
    severity="danger"
    title="Closable Alert"
    onClose={() => console.log('Alert closed!')}>
    Click the button to dismiss this alert.
</NextuiAlert>

Customizing Content

You can customize the start and end content of the alert using the startContent and endContent props:

import { Button } from '@nextui-org/button'
import { PizzaIcon } from 'lucide-react'

function App() {
    return (
        <NextuiAlert
            severity="warning"
            title="Reward Received"
            startContent={<PizzaIcon />}
            endContent={
                <Button size="sm" variant="bordered" color="warning">
                    Eat Now
                </Button>
            }>
            You've got a Pizza!
        </NextuiAlert>
    )
}

To remove the default icon, set startContent to false:

<NextuiAlert severity="info" variant="bordered" startContent="{false}">
    This alert doesn't have an icon.
</NextuiAlert>

Props

Since NextuiAlert extends the Card component from NextUI, it inherits all props from the Card component including shadow, fullWidth, and radius. You can view the complete list of props in the NextUI Card Documentation.

The NextuiAlert component extends the Card component from NextUI, meaning it accepts all Card props in addition to its own that listed on the table below.

Prop	Type	Default	Description
severity	"info" | "warning" | "success" | "danger"	"warning"	Defines the alert type and corresponding color.
variant	"flat" | "bordered" | "solid"	"flat"	Defines the appearance style of the alert.
title	string	undefined	The title text displayed prominently at the top of the alert.
startContent	ReactNode | false	Based on severity	Defines the content or icon at the start of the alert. Set to false to remove the icon.
endContent	ReactNode	undefined	Custom content to display at the end of the alert (optional).
onClose	() => void	undefined	Callback function to handle closing the alert. When provided, a close button is displayed.
