Effective logging in production helps monitor, debug, and track issues — without cluttering the console. 🛠️

🔥 Best Practices for Logging:
✅ 1. Use a Logging Library – Popular ones include Winston, Pino, and Bunyan. They support log levels (info, warn, error), formatting, and transports (e.g., file, console, cloud).

✅ 2. Structure Logs Properly – Log in JSON format for easier parsing and querying later.

✅ 3. Log Levels for Clarity – Define severity levels (debug, info, warn, error, etc.) to control what gets logged.

✅ 4. Write Logs to Files or Databases – Avoid console logs in production. Store logs in files or logging services like Loggly, Papertrail, or Elastic Stack (ELK).

✅ 6. Rotate & Archive Logs – Prevent bloated log files by rotating logs with logrotate or Winston’s DailyRotateFile plugin.

✅ 7. Monitor & Alert – Set up alerts for critical errors using Sentry, Datadog, or Prometheus.

💡 Production logging isn’t just about tracking errors — it’s key to performance monitoring, debugging, and ensuring uptime! 🎉
