Go Logging Patterns

Implement structured, performant logging in Go applications using slog and popular libraries.

Usage

Describe your logging needs and get recommendations for the right approach and implementation.

Examples

  • "Set up structured logging with Go's slog package"
  • "Add request-scoped logging to my HTTP handlers"
  • "Compare slog vs zerolog vs zap for my use case"

Guidelines

  • Recommend slog for new projects using Go 1.21+
  • Show structured logging with typed key-value pairs
  • Cover context-aware logging for request tracing
  • Include log level management and configuration
  • Explain output format choices: JSON for production, text for development
