How can I handle errors using the Winston logging library?

You can handle errors in Winston by using the exceptionHandlers option to log uncaught exceptions.

Can you show me a code example of that?

Sure! Here's a simple example:

const winston = require('winston');

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

throw new Error('This is an uncaught exception!');

What if I want to log errors to a remote server?

You can use a transport like winston-transport to send logs to a remote server. Just configure it in your logger.
