can you write a simple web server script in java script without using express module. index.html should be located in public directory

miniweb_raw.js

const http = require('http');

const fs = require('fs');

const path = require('path');

const PORT = 3000;

const publicDir = 'public';

const handleRequest = (req, res) => {

    // Build file path

    const filePath = path.join(__dirname, publicDir, 'index.html');

    // Check if file exists

    fs.exists(filePath, (exists) => {

        if (!exists) {

            res.statusCode = 404;

            res.end(`File ${filePath} not found!`);

            return;

        }

        // Read file

        fs.readFile(filePath, (err, data) => {

            if (err) {

                res.statusCode = 500;

                res.end(`Error getting the file: ${err}.`);

            } else {

                // If the file is found, set Content-type and send data

                res.setHeader('Content-type', 'text/html');

                res.end(data);

            }

        });

    });

};

const server = http.createServer(handleRequest);

server.listen(PORT, () => {

    console.log(`Server listening on port ${PORT}`);

});

can you rewrite the code using express module ?

miniweb.js

const express = require('express');

const app = express();

const path = require('path');

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

app.get('/', (req, res) => {

  res.sendFile(path.join(__dirname, 'public', 'index.html'));

});

app.listen(3000, () => {

  console.log('Server running on port 3000');

});

can you add a routine for printing out client information ?

miniweb.js

const express = require('express');

const path = require('path');

const requestIp = require('request-ip');

const app = express();

const PORT = 3000;

const publicDir = 'public';

app.use(requestIp.mw());

app.get('/', (req, res) => {

    console.log(`Client IP: ${req.clientIp} - Requested: ${req.url}`);

    res.sendFile(path.join(__dirname, publicDir, 'index.html'));

});

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

app.listen(PORT, () => {

    console.log(`Server listening on port ${PORT}`);

});
