Golang MiddleWare chaining (github.com)

Superb timing as I'm just now implementing some web services in Go and using http.Handler compatible middlewares.

As an alternative there is also Alice[1] but I don't like it's implementation style. Coming from JS and using connect / express what I'd really like is something more like this:

  func helloWorld() http.Handler {
  	return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
  		w.Write([]byte("Hello world!"))
  	})
  }

  func main() {

  	// Wrap the app in Middleware
  	app := SomeMiddlewareLibrary(helloWorld)

  	// Run the middleware in this order
  	app.Use(app.Logger("HELLO-WORLD"))
  	app.Use(app.CORS("*"))
  	app.Use(app.Delay("1s"))

  	// Give the app up to be served
  	http.ListenAndServe(":8080", app)

  }
