Clojurians Log v2

Good morning, I am tripping on the mutation data flow, for example:

#?(:cljs
    ;; client-side
    (m/defmutation delete-employee [{id :employee/id :as params}] ; 
      (action [{:keys [app state] :as env}]          ; 
        (swap! state update :employee/id dissoc id))
      (remote [env] true)                            ; 
      (result-action [{:keys [app state result]}]        ; 
        (println "Did it work?"))))  ; can I use result from server here?
  :clj
    ;; server-side
  (pc/defmutation delete-employee [env {id :employee/id :as params}] ; 
    {::pc/params #{:employee/id}}
    (db/delete-employee id))

;; the db/delete-employee returning

(defn delete-employee [id]
  (comment returns {:delete/result "OK"} if employee id is found)
  (comment returns {:delete/result "FAILED"} if employee id is not found))

(get-in env [:result :body `delete-employee])

You should read about result-action though. (https://book.fulcrologic.com/#_result_action) Then you can decide if you want to use ok-action, which is (per default) called when the network request has the status 200, or if you want to augment result-action to call ok-action only when {:delete/result "OK"}.

@mroerni, Thank you and honestly, I have a hard time reading the Fulcro book, there are soooo many angles to everything. The pointed answer is like hours and hours of reading.

I understand that. 🙂 @holyjak has written a blog post about error handling. https://blog.jakubholy.net/2020/error-handling-in-fulcro/ But I have to admit that it isn't very beginner-friendly as well.
