ReactJS UI Ant Design Switch Component

Last Updated : 21 May, 2021

Ant Design Library has this component pre-built, and it is very easy to integrate as well. Switch components are used to toggle the state of a single setting on or off. We can use the following approach in ReactJS to use the Ant Design Switch Component.

Switch Methods:

blur(): This method is used to remove the focus from the element.
focus(): This method is used to get the focus on the element.

Switch Props:

autoFocus: It is used to get focus when the component is mounted.
checked: It indicates whether the switch is checked or not.
checkedChildren: It is the content that is to be shown when the state is checked.
className: It is used to pass the class name for this switch.
defaultChecked: It indicates whether to set the initial state or not.
disabled: It is used to disable the switch.
loading: It is used to show to loading state of the switch.
size: It is used to denote the size of the switch.
unCheckedChildren: It is the content that is to be shown when the state is unchecked.
onChange: It is the callback function which is triggered when state changes.
onClick: It is the callback function which is triggered on click event.

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.

Project Structure

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, { useState } from 'react'
import "antd/dist/antd.css"; 
import { Switch } from 'antd'; 
  
export default function App() { 
  
  const [currentValue, setCurrentValue] = useState(false) 
  
  return ( 
    <div style={{ display: 'block', width: 700, padding: 30 }}> 
      <h4>ReactJS Ant-Design Switch Component</h4> 
      <Switch onChange={(value) => { 
        setCurrentValue(value) 
      }} /> <br /> 
      <p>Current Mode of Switch: {`${currentValue}`} </p> 
  
    </div> 
  ); 
}
