Two Ways
- Add Bootstrap in React Using NPM
- Adding Bootstrap in React Using CDN:
1. Add Bootstrap in React Using NPM:
use this command to install bootstrap in our project
npm install bootstrap --save
after installing the bootstrap. You must import a CSS file into your React app entry.
If you generated your project using the create-react-app tool, open the src folder, and find the entry file paste.
import 'bootstrap/dist/css/bootstrap.min.css';
You can now use the CSS classes and utilities in your application 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 are integrating Bootstrap into the React.JS project. You use a CDN link. This approach is straightforward for everyone because you need only add a <link> tag for Bootstrap CDN.
Go to your project’s root folder, open the public/index.html file, and paste this code into 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 to 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>
