How can I implement advanced logging in my npm package scripts?

You can use libraries like Winston or Pino for advanced logging. They offer features like log levels, formats, and transports.

Can you show me a basic example of using Winston in a script?

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

const { createLogger, format, transports } = require('winston');

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

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 control over log levels, formatting, and output destinations. It also helps in managing logs in production environments.

Can I customize the log format?

Yes, you can customize the log format in Winston using the format option. You can create your own format or use built-in formats.
