Basic Infomation:

What is react.js?

React.js is one of the popular javascript libraries used to create stateful and reusable UI components. It was developed on Facebook. It is an open-source JavaScript library.

What is Bootstrap?

Bootstrap is the most popular front-end development framework for building responsive web layouts with many components.

Note: I do not recommend to use bootstrap.because bootstrap increase HTML and CSS file size

Two Way:

1. Add Bootstrap in React Using NPM:

use this command install bootstrap in our project.

npm install bootstrap --save

after installing the bootstrap.you will need to import CSS file in your React app entry file.

If you generated your project using the create-react-app tool, open the src folder find the entry file paste.

import 'bootstrap/dist/css/bootstrap.min.css';

You can now use the CSS classes and utilities in your application but if you need to use the JavaScript components.

you will also need to install the jquery and popper.js packages from npm. In your terminal, run the following commands:

npm install jquery popper.js

Next, go to the src/index.js file and add the following imports:

import $ from 'jquery';
import Popper from 'popper.js';
import 'bootstrap/dist/js/bootstrap.bundle.min';

2.   Adding Bootstrap in React Using CDN:

In this method, you integrating Bootstrap with React i.e via use a CDN. This approach is very easiest for everyone because you need only add a <link> tag for Bootstrap CDN.

go to your project’s root folder and open the public/index.html file then paste this code in the <head> section.

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">

If you need only Bootstrap components so in that case, you add JavaScript/jQuery in your React application.

Add the following CDN file before the closing </body> tag:

<script src="https://code.jquery.com/jquery-3.4.1.slim.min.js" integrity="sha384-J6qa4849blE2+poT4WnyKhv5vZF5SrPo0iEjwBvKU7imGFAV0wwj1yYfoRSJoZ+n" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.0/dist/umd/popper.min.js" integrity="sha384-Q6E9RHvbIyZFJoft+2mJbHaEWldlvI9IOYy5n3zV9zzTtmI3UksdQRVvoxMfooAo" crossorigin="anonymous"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.min.js" integrity="sha384-wfSDF2E50Y2D1uUdj0O3uMBJnjuUD4Ih7YwaYd1iqfktj0Uod8GCExl3Og8ifwB6" crossorigin="anonymous"></script>
