Noop duct logger

local.edn

{
  ... ...
  :mocks.boundary.adapter.logger/noop {}
  :duct.middleware.web/log-requests {:logger #ig/ref :mocks.boundary.adapter.logger/noop}
  ... ...
 }

noop.clj

(ns mocks.boundary.adapter.logger.noop
  (:require [duct.logger :as logger]
            [integrant.core :as ig]))

(defrecord TestLogger []
  logger/Logger
  (-log [_ level ns-str file line id event data]))

(defmethod ig/init-key
  :mocks.boundary.adapter.logger/noop
  [_ spec]
  (->TestLogger))

I could simply use this instead:
tail -f app/logs/dev.log | grep -Ev '(INFO|ragtime|jetty)'
