ReactJS UI Ant Design Alert Component

Last Updated : 30 May, 2021

Ant Design Library has this component pre-built, and it is very easy to integrate as well. Alert components are used for urgent interruptions, requiring acknowledgment, that informs the user about a situation. We can use the following approach in ReactJS to use the Ant Design Alert Component.

Alert Props:

action: It is used to define the action of Alert.
afterClose: It is a callback function that is triggered when close animation is finished.
banner: It is used to indicate whether to show as a banner or not.
closable: It is used to indicate whether Alert can be closed or not.
closeText: It is used to define the close text to show.
description: It is used to define the additional content of Alert.
icon: It is used to define the custom icon.
message: It is used to define the content of Alert.
showIcon: It is used to indicate whether to show the icon or not.
type: It is used to indicate the type of Alert styles like success, warning, etc.
onClose: It is a callback function that is triggered when the Alert is closed.

Alert.ErrorBoundary Props:

description: It is used to define the custom error description.
message: It is used to define the custom error message.

Creating React Application And Installing Module:

Step 1: Create a React application using the following command:
```
npx create-react-app foldername
```
Step 2: After creating your project folder i.e. foldername, move to it using the following command:
```
cd foldername
```
Step 3: After creating the ReactJS application, Install the required module using the following command:
```
npm install antd
```

Project Structure: It will look like the following.

Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.

App.js

import React from 'react'
import "antd/dist/antd.css";
import { Alert } from 'antd';

export default function App() {
  return (
    <div style={{
      display: 'block', width: 700, padding: 30
    }}>
      <h4>ReactJS Ant-Design Alert Component</h4>
      <Alert message="This is a Success Alert" type="success" />
      <Alert message="This is a Error Alert" type="error" />
      <Alert message="This is a Warning Alert" type="warning" />
      <Alert message="This is a Info Alert" type="info" />
    </div>
  );
}
