Many of you might have already known about react-bootstrap. Bootstrap components like HTML, CSS and JavaScript have additional dependencies like JQuery which is hard to use in React Applications. To overcome this we have react-bootstrap and reactstrap libraries. Both have a similar approach but there are some minor differences. Let’s see them through simple examples. Here is an example of creating a simple react-bootstrap application. 

npm install -g create-react-app
create-react-app my_app
cd my_app/
npm start

To open this app type “http://localhost:3000/” in your browser. Then add bootstrap using npm.

npm install react-bootstrap bootstrap

In the src folder inside myapp directory open App.js file and write the following code.

// Importing individual react components
import React from 'react';
  
import Jumbotron from 'react-bootstrap/Jumbotron';
import Container from 'react-bootstrap/Container';
import Button from 'react-bootstrap/Button';
  
// App function is created which contains the html
// code that is displayed in the webpage
const App = () => (
  <Container className="p-3">
    <Jumbotron>
      <h1 className="header">Welcome To React-Bootstrap</h1>
      <Button variant="danger">Click here</Button>
    </Jumbotron>
  </Container>
); 
export default App

Type the following code into the index file which is in the same folder.

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';
  
// Importing the Bootstrap CSS
import 'bootstrap/dist/css/bootstrap.min.css';
  
ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);
  
// For faster loading and working of app,
// you can change unregister() to register()
// below. Note this comes with some pitfalls.
// Learn more about service workers: 
// https://bit.ly/CRA-PWA
serviceWorker.unregister();

The output will display a modal that shows Welcome To React-Bootstrap and a click here button.

Now create an application using reactstrap.

npm install -g create-react-app
create-react-app myapp
cd myapp/
npm start

Then add the following Bootstraps.

npm i bootstrap
npm i reactstrap react react-dom

Then write the following code in the App.js file in the src folder inside myapp directory.

// Importing individual react components to 
// reduce the code size
import React, { Component } from 'react';
import { Button } from 'reactstrap';
import { Jumbotron } from 'reactstrap';
import { Row } from 'reactstrap';
import { Col } from 'reactstrap';
import { Container } from 'reactstrap';
  
// This is what is displayed on the webpage
// we create a jumbotron having a message
// and a button
class App extends Component {
    render() {
        return (
            <div>
                <Jumbotron>
                    <Container>
                        <Row>
                            <Col>
                                <h1>Welcome to Reactstrap</h1>
                                <p>
                                    <Button color="danger">
                                        Click Me
                                    </Button>
                                </p>
                            </Col>
                        </Row>
                    </Container>
                </Jumbotron>
            </div>
        );
    }
}
  
export default App;

Then type the following code in index.js file.

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';
  
import 'bootstrap/dist/css/bootstrap.css';
  
ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);
  
// If you want your app to work offline
// and load faster, you can change
// unregister() to register() below. 
// Note this comes with some pitfalls.
// Learn more about service workers: 
// https://bit.ly/CRA-PWA
serviceWorker.unregister();

The outputs are similar for both.
