How can I implement custom logging with Morgan in my Express app?

To implement custom logging with Morgan, you can create a custom token and use it in your logging format. Would you like a code example?

Yes, please provide a code example.

Sure! First, install Morgan using npm: npm install morgan. Then, you can set it up like this:

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

const app = express();

morgan.token('custom', (req, res) => {
    return `Custom log: ${req.method} ${req.url}`;
});

app.use(morgan(':custom'));

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

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

This will log a custom message for each request.

How can I customize the log format further?

You can customize the log format by using predefined tokens or creating your own. For example, you can include response time, status code, etc. Would you like to see more examples?
