How can I customize the log format in Winston?

You can customize the log format in Winston by using the format property when creating a logger instance. You can use built-in formats or create your own.

Can you show me an example of a custom format?

Sure! Here's a simple example:

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

const logger = createLogger({
  format: format.combine(
    format.timestamp(),
    format.printf(({ timestamp, level, message }) => {
      return `${timestamp} [${level}]: ${message}`;
    })
  ),
  transports: [
    new transports.Console()
  ]
});

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

What other built-in formats does Winston provide?

Winston provides several built-in formats like json, simple, colorize, and timestamp. You can combine them as needed.
