ReferenceError: document is not defined on Bootstrap.js

Question

I installed bootstrap, popper.js and jquery as indicated on their official pages. Using the npm package manager. But by requiring them in app.js it sends me this error.

This is app.js

const express = require('express');
const path = require('path');
const morgan = require('morgan');
const helmet = require('helmet');

require('@popperjs/core');
require('jquery');
require('bootstrap');

//Initializations.
const app = express();

//Importing routes.
const indexRoutes = require('./routes/index.router');

//Settings
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'pug');

//Midlewares
app.use(helmet());
app.use(morgan('dev'));
app.use(express.urlencoded({ extended: false }));

//Routes
app.use('/', indexRoutes);

//Static Files
app.use(express.static(path.join(__dirname, 'public')));

//Start Server
app.listen(app.get('port'), () => {
    console.log('Server on port: ', app.get('port'));
});

This is the error. I installed bootstrap, jquery and popper.

npm install bootstrap@next

npm i @popperjs/core

npm install jquery
