How can I use Winston for logging in my Node.js application?

Winston is a versatile logging library for Node.js. You can install it using npm with npm install winston. Would you like to see a basic example?

Yes, please show me a basic example of how to set it up.

Sure! Here's a simple setup:

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');

This will log messages to error.log and combined.log. Do you need help with anything else?

How can I log messages to the console as well?

You can add a console transport to your logger like this:

transports: [
  new winston.transports.Console(),
  new winston.transports.File({ filename: 'error.log', level: 'error' }),
  new winston.transports.File({ filename: 'combined.log' })
]

This will log messages to the console in addition to the files. Let me know if you have more questions!
