goji

GojiMiddleware shows how you would create a default middleware factory and use it to create a Goji compatible middleware.

// Create our middleware factory with the default settings.
mdlw := middleware.New(middleware.Config{
	Recorder: metrics.NewRecorder(metrics.Config{}),
})

// Create our Goji instance.
mux := goji.NewMux()

// Add our middleware.
mux.Use(gojimiddleware.Handler("", mdlw))

// Add our handler.
mux.HandleFunc(pat.Get("/"), http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
	w.WriteHeader(http.StatusOK)
	_, _ = w.Write([]byte("Hello world"))
}))

// Serve metrics from the default prometheus registry.
log.Printf("serving metrics at: %s", ":8081")
go func() {
	_ = http.ListenAndServe(":8081", promhttp.Handler())
}()

// Serve our handler.
log.Printf("listening at: %s", ":8080")
if err := http.ListenAndServe(":8080", mux); err != nil {
	log.Panicf("error while serving: %s", err)
}
