How do I handle body parameters in an Express app?

You can use the body-parser middleware to parse incoming request bodies in Express. Do you need help with installation?

Yes, how do I install body-parser?

You can install it using npm with the command npm install body-parser. Would you like to see an example of how to use it?

Sure, can you provide a code example?

Of course! Here's a simple example:

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

const app = express();
app.use(bodyParser.json());

app.post('/data', (req, res) => {
    console.log(req.body);
    res.send('Data received!');
});

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

This will log the body of any POST request to /data. Do you have any questions about this?
