Along with ant design and chakra-ui, Bootstrap is the most widely used componenet library that you can use to speed up the developpement of your next.js app, giving it a nice professional feel.

how to setup Bootstrap 5

  1. Open your terminal window and navigate to the place you want your Next.js project to locate in then running:
npx create-next-app next_bootstrap

The name is totally up to you.

  1. Navigate to the project root folder:
cd next_bootstrap
  1. Install Bootstrap 5 set with the following command:
npm install [email protected]
yarn add [email protected]
4. Manually import the bootstrap.css file at the very top of your pages/_app.js file:
import 'bootstrap/dist/css/bootstrap.css'

Now, we’re ready to use Bootstrap components in our Next.js app. For example, we will modify our pages/index.js to add a normal button, a ghost button and a date picker :

export default function Home() {
  const onChange = () => {};
  return (
    <div style={{ padding: 100 }}>
        <Button type="primary">Primary Button</Button>

this is the result :

See the difference without bootstrap :

  1. Manually import bootstrap's javascript file in your pages/_app.js file:

With the previous steps, the components that need bootsrap's Javascript (like dropdown, carousel, ...) won"t work even if you import bootstap's javascript file in the top of _app.js.

What we should do is import the file via the useEffect hook : the _app.js file will look like :

import 'bootstrap/dist/css/bootstrap.css'
import '../styles/globals.css'
import { useEffect } from "react";

function MyApp({ Component, pageProps }) {
  useEffect(() => {
  }, []);

  return <Component {...pageProps} />;

export default MyApp

Now our components will work normally, exemple a dropdown menu :

export default function Home() {
  return (
    <div className="container p-3">

      <div className="dropdown m-3">
          className="btn btn-secondary dropdown-toggle"
        <ul className="dropdown-menu" aria-labelledby="dropdownMenuButton1">
            <a className="dropdown-item" href="#">
              Option 1
            <a className="dropdown-item" href="#">
              Option 2
            <a className="dropdown-item" href="#">
              Option 3

the result :

reactstrap and react-bootstrap

If you want to use ready-to-use Bootstrap Components redesigned internally as JSX, without the need to use JQuery or Javascript with direct DOM manipulation you can use two libraries :

  • reactstrap

this library uses bootstrap class components :

import React from 'react';
import { Button, Modal, ModalHeader, ModalBody, ModalFooter } from 'reactstrap';

class ModalExample extends React.Component {
  constructor(props) {
    this.state = {
      modal: false

    this.toggle = this.toggle.bind(this);

  toggle() {
    this.setState(prevState => ({
      modal: !prevState.modal

  render() {
    return (
        <Button color="danger" onClick={this.toggle}>{this.props.buttonLabel}</Button>
        <Modal isOpen={this.state.modal} toggle={this.toggle} className={this.props.className}>
          <ModalHeader toggle={this.toggle}>Modal title</ModalHeader>

            <Button color="primary" onClick={this.toggle}>Do Something</Button>{' '}
            <Button color="secondary" onClick={this.toggle}>Cancel</Button>

export default ModalExample; 


this library uses react hooks and functions :

function MyVerticallyCenteredModal(props) {
  return (
      <Modal.Header closeButton>
        <Modal.Title id="contained-modal-title-vcenter">
          Modal heading
        <h4>Centered Modal</h4>
          Cras mattis consectetur purus sit amet fermentum. Cras justo odio,
          dapibus ac facilisis in, egestas eget quam. Morbi leo risus, porta ac
          consectetur ac, vestibulum at eros.
        <Button onClick={props.onHide}>Close</Button>

function App() {
  const [modalShow, setModalShow] = React.useState(false);

  return (
      <Button variant="primary" onClick={() => setModalShow(true)}>
        Launch vertically centered modal

        onHide={() => setModalShow(false)}

render(<App />);
