How do I configure Winston for logging in my Node.js application?

To configure Winston, first install it using npm: npm install winston. Then, you can set it up like this:

Can you show me a basic example of the configuration?

Sure! Here's a simple example:

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');

What if I want to log to the console as well?

You can add a console transport like this:

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