How can I implement logging in my Node.js application?

You can use libraries like Winston or Morgan for logging in Node.js. Would you like a code example?

Yes, please provide a code example using Winston.

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

const winston = require('winston');

const logger = winston.createLogger({
  level: 'info',
  format: winston.format.json(),
  transports: [
    new winston.transports.File({ filename: 'error.log', level: 'error' }),
    new winston.transports.File({ filename: 'combined.log' })
  ]
});

logger.info('This is an info message');
logger.error('This is an error message');

What are the benefits of using a logging library instead of console.log?

Using a logging library allows for better log management, different log levels, and the ability to write logs to files or external services.

Can I log to a remote server?

Yes, you can configure Winston to log to remote servers using transports like HTTP or other third-party services.
