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 { AutoComplete } from 'antd';   export default function App() {     const [currentValue, setCurrentValue] = useState('')   const options = [     {label: 'One', value: 'One'},     {label: 'Two', value: 'Two'},     {label: 'Three', value: 'Three'},     {label: 'Four', value: 'Four'},     {label: 'Five', value: 'Five'}   ]     return (     <div style={{ display: 'block',                   width: 700, padding: 30 }}>       <h4>ReactJS Ant-Design AutoComplete Component</h4>       <AutoComplete         options={options}         style={{ width: 200 }}         onSelect={(value)=> {             setCurrentValue(value)         }}         placeholder="Enter your text"      /> <br />         <p>Selected Value {`${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:
