Types

type Option added in v1.2.0 

type Option func(server *http.Server)

type Server 

type Server struct {
	Signals []os.Signal
	Mux     http.Handler
	Addr    string
}

func (*Server) ListenAndServe 

func (s *Server) ListenAndServe(ctx context.Context, options ...Option) error

ListenAndServe listens on the TCP network address s.Addr and then calls Serve to handle requests on incoming connections.

Farther it listens context Done channel and then calls Shutdown for the http server

Example 
srv := Server{
	Mux:  http.NewServeMux(),
	Addr: ":8111",
}
srv.SetSignals(os.Interrupt, syscall.SIGTERM)

c := make(chan os.Signal, 1)
signal.Notify(c, os.Interrupt, syscall.SIGTERM)

// starting server
go func() {
	_ = srv.ListenAndServe(context.Background())
}()

// sending the signal
time.Sleep(time.Microsecond * 200)
_ = syscall.Kill(syscall.Getpid(), syscall.SIGTERM)

<-c

Output:

func (*Server) SetSignals 

func (s *Server) SetSignals(sig ...os.Signal)

SetSignals sets list of signals to be notified

Example 
server := Server{}
server.SetSignals(os.Interrupt, syscall.SIGTERM)
