Initializer

Initializer is a simple library to initialize main go service.

go get github.com/worldline-go/initializer

Usage

Default logger is zerolog, use initializer.WithLogger(initializer.Slog) to use standard log.

var (
	version = "v0.0.0"
	commit  = "-"
	date    = "-"
)

func main() {
	// run the application
	initializer.Init(
		run,
		initializer.WithMsgf("awesome-service version:[%s] commit:[%s] date:[%s]", version, commit, date),
		// if you want to close the application after a certain time without waiting the waitgroup
		// initializer.WithWaitTimeout(0),  // 0 means no timeout as default (time.Duration)
		initializer.WithOptionsLogz(
			logz.WithCaller(false),
			logz.WithLevel(zerolog.LevelDebugValue),
		))
}

func run(_ context.Context, _ *sync.WaitGroup) error {
	// Do something here.
	log.Info().Msg("Hello World!")

	return fmt.Errorf("something went wrong")
}
