How can I log requests in my Express.js app using Morgan?

You can log requests in your Express.js app using the Morgan middleware. First, install it using npm: npm install morgan. Then, require it in your app and use it as middleware.

Can you show me a code example?

Sure! Here's a simple example:

const express = require('express');
const morgan = require('morgan');

const app = express();

app.use(morgan('combined')); // Logs requests in Apache combined format

app.get('/', (req, res) => {
  res.send('Hello World!');
});

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

What are the different formats I can use with Morgan?

Morgan provides several predefined formats like 'combined', 'common', 'dev', 'short', and 'tiny'. You can also create a custom format if needed.

Is Morgan suitable for production use?

Yes, Morgan is suitable for production, but you might want to log to a file instead of the console for better performance and persistence.
