What are some examples of middleware in Express API?

Can you give me some examples of middleware in an Express API?

Sure! Middleware in Express can be used for various purposes like logging, authentication, and error handling. For example, you can use 'morgan' for logging requests.

What does the 'body-parser' middleware do?

The 'body-parser' middleware is used to parse incoming request bodies in a middleware before your handlers, making it easier to access the data.

Can you show me a code snippet using middleware?

Absolutely! Here's a simple example:

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

const app = express();
app.use(bodyParser.json()); // Middleware to parse JSON bodies

app.post('/data', (req, res) => {
    res.send(req.body);
});

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