I'm using useSyncExternalStore to tap into an atom. I was curious how it re-renders and I forced a not stable snapshot of data with merge (the commented version) and got multiple renders error. So: Can I conclude that a deref on the atom that is backed by a map is a stable reference? It appears so and that is cool, and the consequence of it: exposing it to react appears to be simple. Can you share your thoughts on this ?

(def ^:private cache (atom {}))

(def ^:private notifiers (atom #{}))
(add-watch cache :logger
          (fn [_key _atom _old-state _new-state]
            (doseq [notify @notifiers]
              (notify))))

(defn ^:private subscribe
  [notify]
  (swap! notifiers conj notify)
  (fn [] (swap! notifiers disj notify)))

(defn use-paginated-query-cache
  [query-name ]
  (useSyncExternalStore subscribe (fn [] (get @cache query-name)))
  ; (useSyncExternalStore
  ;   subscribe
  ;   (fn []
  ;    (merge {} (get @cache query-name))))
  )

Hei guys, I’m trying to integrate Supabase (firebase competitor) but I get stuck trying to call a nested object function signUp (https://supabase.com/docs/reference/javascript/auth-signup) From the docs: Create client:

import { createClient } from '@supabase/supabase-js'

// Create a single supabase client for interacting with your database 
const supabase = createClient('', 'public-anon-key')

const { user, session, error } = await supabase.auth.signUp({
  email: '',
  password: 'example-password',
})

(defonce ^SupabaseClient supabase-client (create-client supabase-url supabase-key))


(defn sign-up
  [email password]
  (let [sign-up-fn (-> supabase-client .-auth .-signUp)]
    (sign-up-fn (clj->js {:email email :password password}))))

(comment
  (-> (sign-up "" "pass123omg_crazy")
      (.then js/console.log)))
