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 from 'react'import "antd/dist/antd.css"; import { Collapse } from 'antd'; const { Panel } = Collapse; export default function App() { return ( <div style={{ display: 'block', width: 700, padding: 30 }}> <h4>ReactJS Ant-Design Collapse Component</h4> <Collapse> <Panel header="neveropen" key="1"> <p>Greetings from neveropen</p> </Panel> <Panel header="Computer Science" key="2"> <p>This is Best computer Science Portal</p> </Panel> </Collapse> </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:
