Middleware registry / lookup

[ikitommi]

It could be useful to be able to reference Middleware by their distinct names instead of instances. Names would be looked from explicit registry. Registry could be a map (name -> middleware) or via a registry construcing function , consuming a vector of Middleware instances. :name of Middleware could be used as a key.

Something like:

(extend-protocol IntoMiddleware
  #?(:clj  clojure.lang.Keyword
     :cljs cljs.core.Keyword)
  (into-middleware [this _ {:keys [middleware-registry]}]
    (into-middleware (middleware-registry this))))

allowing:

(require '[reitit.ring :as ring])

(ring/ring-router
  ["/api" {:middleware [::api-format]}
   ["/ping" (constantly {:status 200, :body {:ping "pong"}})]]
  {:middleware-registry {::api-format ....})
