Answer
Structured logging formats like JSON are used with tools such as Winston or Pino for centralized log management.
Quick Answer
Use different log levels (debug, info, warn, error) and enable only the appropriate level per environment — verbose in dev, errors-only in production. Use structured JSON logging (Pino, Winston) for machine-readability. In production, ship logs to a centralized platform (Datadog, CloudWatch, Elastic) for search, alerting, and correlation across services.
