Javascript 我可以使用使用node.js创建的本地主机来存储我网站上提交的所有数据吗没有SQL或任何数据库.只有HTML语言

const express = require('express');
const bodyParser = require('body-parser');
const fs = require('fs');
const path = require('path');
const app = express();

// Middleware to parse JSON and urlencoded data
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

app.post('/saveInput', (req, res) => {
    // Get the message from the request body
    const { Nome, Questio } = req.body;
    console.log( Nome, Questio )
    // Write the message to a JSON file
    const data = JSON.stringify({  Nome, Questio }) + '\n';
    fs.appendFile(path.join(__dirname, 'message.json'), data, (err) => {
        if (err) {
            console.error('Error writing message to file:', err);
            res.status(500).send('Internal Server Error');
        } else {
            console.log('Message written to file');
            res.status(200).send('Message written to file');
        }
    });
});

// Start the server
const port = 3000;
app.listen(port, () => {
    console.log(`Server running at http://127.0.0.1:${port}/`);
});

<script>
document.getElementById('formCritic').addEventListener('submit', function(event) {
    event.preventDefault(); // Prevent the default form submission behavior

    const formData = new FormData(this);
    fetch('http://localhost:3000/saveInput', {
        method: 'POST',
        body: formData
    })
});
