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. folder name, 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 react-bootstrap 
npm install bootstrap
Project Structure: It will look like the following.
Project Structure
Fade Component Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.
Filename: App.js
Javascript
import React, { useState } from 'react';import 'bootstrap/dist/css/bootstrap.css';import Button from 'react-bootstrap/Button'import Fade from 'react-bootstrap/Fade' export default function App() {   const [open, setOpen] = useState(false);   return (    <div style={{ display: 'block',                  width: 700, padding: 30 }}>      <h4>React-Bootstrap Fade Component</h4>      <div style={{ width: 660, height: 'auto' }}>        <Button          variant="link"          onClick={() => setOpen(!open)}          aria-expanded={open}          aria-controls="fadeID"        >          Click to see Fade Effect!      </Button>        <Fade in={open}>          <div id="fadeID"            style={{              width: 300,              textAlign: 'justify'            }}          >            Greetings from GeeksforGeeks, How are you?            Stay safe            Always keep yourself health.            Study and work hard.          </div>        </Fade>      </div>    </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:
