		DisableStderr: true,
	})

	if err != nil {
		log.Fatal(err)
	}

	handler, err := logx.NewHandler(writer, &logx.HandlerOptions{
		Level:      slog.LevelInfo,
		TimeFormat: time.TimeOnly,
	})

	logger, err := logx.New(
		logx.WithHandlers(handler),
	)

	if err != nil {
		log.Fatal(err)
	}

	// register close hooks
	logger.OnClose(func() error {
		return writer.Close()
	})

	defer logger.Close()

	slog.SetDefault(logger.Slog())

	slog.Info("hello world")
}

package main

import (
	"github.com/ginx-contribs/logx"

func main() {
	err := sentry.Init(sentry.ClientOptions{

		EnableTracing: false,
	})
	if err != nil {
		log.Fatal(err)
	}

	logger, err := logx.New(
		logx.WithHandlers(
			slog.NewJSONHandler(os.Stderr, nil),
			slogsentry.Option{Level: slog.LevelDebug}.NewSentryHandler(),
		),
	)
	if err != nil {
		log.Fatal(err)
	}
	defer logger.Close()

	logger.OnClose(func() error {
		return sentry.Flush(2 * time.Second)
	})

	slog.SetDefault(logger.Slog())

	slog.Info("hello world")
