ReactJS UI Ant Design Switch Component

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>
  );
}

Step to Run Application: Run the application using the following command from the root directory of the project:

npm start

Output: Now open your browser and go to http://localhost:3000/, you will see the following output:
