1. First, we need fresh reactjs setup, and for that, we need to run below commands into out terminal, and also we should have latest node version installed on our system:

npx create-react-app my-awesome-project

cd my-awesome-project

npm start

2. Now we need to run below commands into our project terminal to get bootstrap and related modules into our reactjs application:

npm install [email protected] --save

npm start //For start project again

3. Finally for the main output, we need to add below code into our my-awesome-project/src/App.js file or if you have fresh setup then you can replace my-awesome-project/src/App.js file code with below code:

import React from 'react';
import './App.css';
import 'bootstrap/dist/css/bootstrap.min.css';


function App() {
  
	return (
		<div>
			<div class="preloader">
    <div class="loader">
        <div class="loader-outter"></div>
        <div class="loader-inner"></div>

        <div class="indicator"> 
            <svg width="16px" height="12px">
                <polyline id="back" points="1 6 4 6 6 11 10 1 12 6 15 6"></polyline>
                <polyline id="front" points="1 6 4 6 6 11 10 1 12 6 15 6"></polyline>
            </svg>
        </div>
    </div>
</div>
		</div>
	);
}
export default App;

4. Now we need to add below code into our my-awesome-project/src/App.css file :

body{margin-top:20px;}
