How to add Bootstrap in Next.js


To use Bootstrap in a Next.js app, you will need to install the Bootstrap library and include its styles in your app. Here is an example of how you can add Bootstrap to a Next.js app:

First, install Bootstrap by running the following command in your terminal:

npm install bootstrap

Next, create a file called _app.js in the pages directory of your Next.js app. This file allows you to customize the app component provided by Next.js. In the _app.js file, import the Bootstrap styles by adding the following line at the top of the file:

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

Then, you can use the Bootstrap classes in your component templates to apply Bootstrap styles to your app.

Here is an example of how you can use Bootstrap to create a navbar in a Next.js app:

import Head from 'next/head';

function MyApp({Component, pageProps}) {
    return (
                <title>My App</title>
            <nav class="navbar navbar-expand-lg navbar-light bg-light">
                <a class="navbar-brand" href="/">My App</a>
                <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav"
                        aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
                    <span class="navbar-toggler-icon"></span>
                <div class="collapse navbar-collapse" id="navbarNav">
                    <ul class="navbar-nav">
                        <li class="nav-item active">
                            <a class="nav-link" href="/">Home</a>
                        <li class="nav-item">
                            <a class="nav-link" href="/about">About</a>
                        <li class="nav-item">
                            <a class="nav-link" href="/contact">Contact</a>
            <Component {...pageProps} />

export default MyApp;

This will create a navbar with a brand name and a toggle button for responsive layouts. The navbar also has links for the “Home”, “About”, and “Contact” pages.
