Simple controller mechanism for Pedestal applications.
The main idea behind controllers is to define a set of handlers that shares the same interceptors/ settings, making the entire process less error-prone and easy to maintain.
(defcontroller Product
(interceptors [common-interceptors
[auth :only [:create]]
[json-body :except [:search]]])
(handler create
(fn [request]
(let [{{data :data} :params} request]
(ring-resp/response (build-product! data)))))
(handler search
(fn [request]
(let [{{query :query} :params} request]
(ring-resp/response (render (search query)))))))
(interceptors Product) ;; [default auth]
(handlers Product) ;; {:create (fn ...) :search (fn ...)}
(handler Product :create) ;; (fn ... )With the controllers, it's possible to add routes without defining interceptors configuration:
(def routes
(remap-routes
#{["/products" :post Product :create]
["/products/search" :get Product :search]
;; Although it's not mandatory and the old "syntax" still valid.
["/about" :get (conj common-interceptors `about-page)]}))Copyright © 2019 Thiago Lewin
