How do I implement structured logging in my application?

To implement structured logging, you can use libraries like Serilog for .NET or Winston for Node.js. Would you like a code example?

Yes, please provide a code example for Node.js.

Here's a simple example using Winston:

const winston = require('winston');

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

logger.info('User logged in', { userId: 123 });

What are the benefits of using structured logging?

Structured logging allows for better querying and analysis of logs, making it easier to identify issues and track application behavior.
