[twitter-bootstrap] How to include bootstrap css and js in reactjs app?

I am newb to reactjs, I want to include bootstrap in my react app

I have installed bootstrap by npm install bootstrap --save

Now, want to load bootstrap css and js in my react app.

I am using webpack.

webpack.config.js

var config = {
    entry: './src/index',

    output: {
        path: './',
        filename: 'index.js'
    },

    devServer: {
        inline: true,
        port: 8080,
        historyApiFallback: true,
        contentBase:'./src'
    },

    module: {
        loaders: [
            {
                test: /\.js?$/,
                exclude: /node_modules/,
                loader: 'babel',

                query: {
                    presets: ['es2015', 'react']
                }
            }
        ]
    }
};

module.exports = config;

My issue is "how to include bootstrap css and js in reactjs app from node_modules?" How to setup for bootstrap to include in my react app?

After installing bootstrap in your project "npm install --save [email protected]" you have to move to the index.js file in the project SRC folder and import bootstrap from node module package.

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

If you like you can get help from this video, sure it will help you a lot.

Import Bootstrap In React Project

You can't use Bootstrap Jquery based Javascript components in React app, as anything that tries to manipulate DOM outside React is considered bad practice. Here you can read more info about it.

How to include Bootstrap in your React app:

1) Recommended. You can include raw CSS files of Bootstrap as the other answers specify.

2) Take a look at react-bootstrap library. It is exclusively written for React.

3) For Bootstrap 4 there is reactstrap

Bonus

These days I generally avoid Bootstrap libraries which provide ready to use components (above-mentioned react-bootstrap or reactstrap and so on). As you are becoming dependent on the props they take (you can't add custom behavior inside them) and you lose control over DOM that these components produce.

So either use only Bootstrap CSS or leave Bootstrap out. A general rule of thumb is: If are not sure whether you need it, you don't need it. I've seen a lot of applications which include Bootstrap, but using the only small amount of CSS of it and sometimes the most of this CSS is overridden by custom styles.

I try with instruction:

npm install bootstrap
npm install jquery popper.js

then in src/index.js:

import 'bootstrap/dist/css/bootstrap.min.css';
import $ from 'jquery';
import Popper from 'popper.js';
import 'bootstrap/dist/js/bootstrap.bundle.min';
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import registerServiceWorker from './registerServiceWorker';

ReactDOM.render(<Dropdown />, document.getElementById('root'));
registerServiceWorker();

Full answer to give you jquery and bootstrap since jquery is a requirement for bootstrap.js:

Install jquery and bootstrap into node_modules:

npm install bootstrap
npm install jquery

Import in your components using this exact filepath:

import 'jquery/src/jquery'; //for bootstrap.min.js
//bootstrap-theme file for bootstrap 3 only
import 'bootstrap/dist/css/bootstrap-theme.min.css';
import 'bootstrap/dist/css/bootstrap.min.css';
import 'bootstrap/dist/js/bootstrap.min.js';

Somehow the accepted answer is only talking about including css file from bootstrap.

But I think this question is related to the one here - Bootstrap Dropdown not working in React

There are couple of answers that can help -

1. https://stackoverflow.com/a/52251319/4266842
2. https://stackoverflow.com/a/54188034/4266842

I just want to add that installing and importing bootstrap in your index.js file won't be enough for using bootstrap components. Every time you want to use a component you should import it, like: I need to use a container and a row

    <Container>
        <Row>
        <Col sm={4}> Test </Col>
        <Col sm={8}> Test </Col>
        </Row>
</Container>

You should import in your js file

import {Container, Row, Col} from 'react-bootstrap';

I too had a similar scenario. My setup was as indicated below

npm install create-react-app

This will provide you with a boiler-plate code setup to begin. Play around with the App.js file for the main logic.

Later you can use bootstrap CDN in index.html created by the CLI tool. or

npm install bootstrap popper jquery

and then simply include this in the App.js file.

import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap/dist/js/bootstrap.bundle'

Few authors have mentioned using className attribute instead of class, but in my case, both were working like below. But if you use class and look at console in developer tools on browser, you will see error for using class.So use className instead.

    <div className="App" class = "container"> //dont use class attribute

And don't forget to remove the default CSS imports to avoid conflicts with bootstrap.

Hope that helps, Happy coding!!!

Since Bootstrap/Reactstrap has released their latest version i.e. Bootstrap 4 you can use this by following these steps

1. Navigate to your project
2. Open the terminal

3. I assume npm is already installed and then type the following command

   npm install --save reactstrap react react-dom

This will install Reactstrap as a dependency in your project.

Here is the code for a button created using Reactstrap

import React from 'react';_x000D_
import { Button } from 'reactstrap';_x000D_
_x000D_
export default (props) => {_x000D_
  return (_x000D_
    <Button color="danger">Danger!</Button>_x000D_
  );_x000D_
};

You can check the Reactstrap by visiting their offical page

Just in case if you can use yarn which is recommended for React apps,

you can do,

yarn add [email protected] // this is to add bootstrap with a specific  version

This will add the bootstrap as a dependency to your package.json as well.

{
  "name": "my-app",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "bootstrap": "4.1.1", // it will add an entry here
    "react": "^16.5.2",
    "react-dom": "^16.5.2",
    "react-scripts": "1.1.5"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  }
}

After that just import bootstrap in your index.js file.

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

Please follow below link to use bootstrap with React. https://react-bootstrap.github.io/

For installation :

$ npm install --save react react-dom
$ npm install --save react-bootstrap

------------------------------------OR-------------------------------------

Put Bootstrap CDN for CSS in tag of index.html file in react and Bootstrap CDN for Js in tag of index.html file. Use className instead of class follow below index.html

<!doctype html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <meta name="theme-color" content="#000000">

    <link rel="shortcut icon" href="../src/images/dropbox_logo.svg">
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

You can just import the css file wherever you want. Webpack will take care to bundle the css if you configured the loader as required.

Something like,

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

And the webpack config like,

loaders: [{ test: /\.css$/, loader: 'style-loader!css-loader' }]

Note: You have to add font loaders as well, else you would be getting error.

Hope this is helpful ;)

Step 1: using NPM install this bellow command

npm install --save reactstrap@next react react-dom

Step 2: example index.js main script import bellow command

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

Step 3: UI components refer bellow website reactstrap.github.io

Via npm, you would run the folowing

npm install bootstrap jquery --save
npm install css-loader style-loader --save-dev

If bootstrap 4, also add dependency popper.js

npm install popper.js --save

Add the following (as a new object) to your webpack config

loaders: [
    {
      test: /\.css$/,
      loader: 'style-loader!css-loader'
    }

Add the following to your index, or layout

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

Simple Solution (2020) is as follows :-

1. npm install --save jquery popper.js
2. npm install --save bootstrap
3. npm install --save style-loader css-loader
4. update webpack.config.js, you've to tell webpack how to handle the bootstrap CSS files hence you've to add some rules as shown :-

5. Add some imports in the entry point of your React Application (usually it's index.js), place them at the top make sure you don't change the order.

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

import $ from "jquery";

import Popper from "popper.js";

import "bootstrap/dist/js/bootstrap.bundle.min";

6. These steps should help you out, please comment if there's some problem.

If you use CRA(create-react-app) in your project, you can add this:

npm install react-bootstrap bootstrap

If you use bootstrap in your app and if it's not working, then use this in index.html :

<link
  rel="stylesheet"
  href="https://maxcdn.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css"
  integrity="sha384-GJzZqFGwb1QTTN6wy59ffF1BuGJpLSa9DkKMp0DgiMDm4iYMj70gZWKYbI706tWS"
  crossorigin="anonymous"
/>

I did the above to solve similar problem. Hopefully this is useful to you :-)

you can install it dirctly via

$ npm install --save react react-dom
$ npm install --save react-bootstrap

then import what you really need from the bootstrap like :

import Button from 'react-bootstrap/lib/Button';

// or

import  Button  from 'react-bootstrap';

and also you can install :

npm install --save reactstrap@next react react-dom

check this out click here .

and for the CSS you can read this link also carfuly

read here

npm install --save bootstrap 

and add this import statement into your index.js file

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

or You could simply add CDN in your index.html file.

Here is how to include latest bootstrap
https://react-bootstrap.github.io/getting-started/introduction

1.Install

npm install react-bootstrap bootstrap

2. then import to App.js import 'bootstrap/dist/css/bootstrap.min.css';

3. Then you need to import the components that you use at your app, example If you use navbar, nav, button, form, formcontrol then import all of these like below:

import Navbar from 'react-bootstrap/Navbar'
import Nav from 'react-bootstrap/Nav'
import Form from 'react-bootstrap/Form'
import FormControl from 'react-bootstrap/FormControl'
import Button from 'react-bootstrap/Button'


// or less ideally
import { Button } from 'react-bootstrap';
