middleware.Logger() has been deprecated. For request logging, use middleware.RequestLogger() or middleware.RequestLoggerWithConfig().

middleware.RequestLogger() replaces middleware.Logger(), offering comparable configuration while relying on the Go standard library’s new slog logger.

The previous default output format was JSON. The new default follows the standard slog logger settings. To continue emitting request logs in JSON, configure slog accordingly:

:::go
slog.SetDefault(slog.New(slog.NewJSONHandler(os.Stdout, nil)))
e.Use(middleware.RequestLogger())

If you are developing anything more substantial than a demo, use middleware.RequestLoggerWithConfig()
