Separate Log Levels

This allows applications to store stable production logs in files while showing more detailed information in the console during development or debugging sessions.

Configuration is controlled through:

• MinLevel
• ConsoleMinLevel

Example configuration:

package main

import (
	"log/slog"

	"github.com/netlifeguru/logger"
)

func main() {
	closer, err := logger.Init(logger.Config{
		TerminalOutput:  true,
		MinLevel:        slog.LevelInfo,
		ConsoleMinLevel: slog.LevelDebug,
	})

	if err != nil {
		slog.Error(err.Error())
	}

	defer closer.Close()

	slog.Debug("debug message")
	slog.Info("application started")
	slog.Warn("warning message")
}

In this configuration:

• log files store:
  • INFO
  • WARN
  • ERROR
• terminal output displays:
  • DEBUG
  • INFO
  • WARN
  • ERROR

Example terminal output:

2026-05-11 11:42:18 DBG debug message
2026-05-11 11:42:18 INF application started
2026-05-11 11:42:18 WRN warning message

Example file output:

{
  "time": "2026-05-11T11:42:18.102391+02:00",
  "level": "INFO",
  "msg": "application started"
}

If ConsoleMinLevel is not specified, terminal output automatically uses the same level as MinLevel.

This separation is especially useful for:

• local debugging
• development environments
• production observability
• reducing noise in persisted logs
