addingbackground image in nodejs

const express = require('express');
const path = require('path');
const app = express();

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

app.get('/', function(req, res) {
  res.sendFile('index.html', { root: path.join(__dirname, 'views') });
});

app.listen(3000, function() {
  console.log('Server is running on port 3000');
});

Create a folder called "public" in the root of your project.

Inside the "public" folder, create a folder called "images" and place your background image inside it.

Create a folder called "views" in the root of your project.

Inside the "views" folder, create an "index.html" file and add the necessary HTML and CSS to display the background image.

Then, with this Node.js code, you are serving the static files from the "public" directory and rendering the "index.html" file when someone visits the root URL.
