There are several effective strategies for error logging in Node.js, including using libraries like Winston or Bunyan, implementing centralized logging, and ensuring proper error handling in your application.

Can you explain how to use Winston for logging?

Sure! Winston is a versatile logging library. You can install it using npm, then create a logger instance and define transports for where you want to log your messages, such as console or files.

Transports in Winston are essentially the destinations for your log messages. You can configure multiple transports to log to different places, like the console, files, or even remote servers.
