service

Golang library that handle the complexity of running long-living goroutines (like a http server).

func main() {
    ctx := context.Background()

	listener1, err := net.Listen("tcp", ":8080")
	if err != nil {
		panic(fmt.Errorf("unable to create listener: %v", err))
	}

	server1 := netservice.Serve(
		&http.Server{Handler: http.HandlerFunc(func(rw http.ResponseWriter, r *http.Request) {
			rw.WriteHeader(http.StatusTeapot)
		})},
		listener1,
		netservice.ServerWithServeErrorTransformer(func(err error) error {
			if errors.Is(err, http.ErrServerClosed) {
				return nil
			}
			return err
		}),
	)

	listener2, err := netservice.NewListener(ctx, ":9090")
	if err != nil {
		panic(fmt.Errorf("unable to create listener: %v", err))
	}

	server2 := netservice.Serve(
		&http.Server{Handler: http.HandlerFunc(func(rw http.ResponseWriter, r *http.Request) {
			rw.WriteHeader(http.StatusOK)
		})},
		listener2,
		netservice.ServerWithServeErrorTransformer(func(err error) error {
			if errors.Is(err, http.ErrServerClosed) {
				return nil
			}
			return err
		}),
	)

	if err := service.Run(ctx, server1, server2); err != nil {
		panic(fmt.Errorf("unable to run services: %v", err))
	}
}
