Clojurians Log v2

I implemented a rudimentary slash-handler for my front-end. Front-end is an SPA, and there are places where the backend has to allow whatever *path , which negates the ring slash handler. So I'm doing this:

(defn start! []
  (rfe/start!
   (reitit/router routes {:conflicts nil})
   #(rf/dispatch [::handle-navigate %])   ;; <--- on-navigate callback dispatches reframe navigation-handling event
   ...opts...))

(rf/reg-event-fx
 ::handle-navigate
 (fn [{:keys [db]} [_ new-match]]
   (let [href (.-href js/location)]
     (if (str/ends-with? href "/")        ;; <--- naïvely detect a trailing slash
       {:fx [[::replace-href (subs href 0 (dec (count href)))]]}
       {:db (assoc db ::route new-match ::controllers (some->> new-match (rfc/apply-controllers (::controllers db))))}))))

(rf/reg-fx
 ::replace-href
 (fn [url] (.replace js/location url)))

I'm not planning on publishing url's with trailing slashes, and I use url-constructing functions everywhere, so I shouldn't be accidentally generating any. How needful will this be, maybe for the odd user who is attempting to type in a url from memory? But anyway, it works.
