How can I integrate a logger into my application?

You can integrate a logger by using libraries like Winston or Log4j. Which programming language are you using?

I'm using Node.js. Can you give me an example with Winston?

Sure! First, install Winston using npm: npm install winston. Then, you can set it up like this:

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('Logger initialized!');

What are the benefits of using a logger?

Using a logger helps you track application behavior, debug issues, and maintain logs for audits or monitoring.
