Clojurians Log v2

You'll want to use regular strings as keys. Your keywords are likely getting coerced to something like [Object object] and everything comparing the same.

Ahha ok

I thought

(pr-str key)

This is what I use. So I thought even if I send in :saved-db it would be made into ":saved-db" string and it would work. Have you implemented this differently?

pr-str should be good.

The weird thing is that my functions are not getting errors or anything. They are running successfully and it seems like things are getting extracted correctly from the storage while the app is running. But when the app shutsdown and I start it up again, the same keys return empty. 😮

(ns reagent-app-project.db
  (:require ["@react-native-community/async-storage" :default AsyncStorage]
            [cljs.reader :refer [read-string]]))

(def ^:private async-storage AsyncStorage)

I am also using (read-string result) to make it into clojure map from string 😮

Is the problem perhaps how I am getting the async-storage on startup? How do you connect back to the same async storage on startup of app? 😮

Hmmm.. I see. I will try to make changes on my end see if it works then. Thank you so much! 🙂 You are ignoring the errors from the methods I see. Is this for performance reasons or just not interesting and usually it works flawlessly?

I don't ignore them, but they're handled downstream. AsyncStorage is pretty reliable though

What does it mean to handle them downstream? I am a scientist more than a programmer so there are things I am not familiar with 😮

I handle errors differently each time I call async-storage/get-edn - since it's a promise, I handle errors in a callback depending on what is appropriate to do for that specific failure. If that makes sense

Downstream = in other parts of the code

Ah! I understand! Thanks for explaining! ^^

@jimberlage, are you doing something like this in your init function:

(rf/dispatch-sync [:initialize-db (if-let [storage (get-edn :saved-db)]
                                    storage
                                    default-db)])

?

I am not quite sure how to work with promise objects :x

Is it just wrapping it in try catch or?

I really don't understand how to deref #object[Promise [object Object]]. :x

I found the problem! It could not read React Native Animation object.

Got to figure out how to add such an object to the edn reader. :x

That's a tricky one. JS objects are tough to print well. To tell you the truth, I don't use re-frame anymore, I just know how to use it from past experience. Your call to get-edn looks OK, but you probably need to have it be an effect since it's not going to return immediately

I don't know if this is the best way of doing it, but what I am doing is that I am loading the app-db, then I am sending it into a function that sets all the animation values to the value they should be, then the app starts up. What do you guys think? Is this a good way of doing it? I am basically saving the actual values in the DB and letting the animated value objects be (r/atoms).

(defn init-animations [db]
  (let [current-opacity (get-in db [:animation :bottom-modal-bg-fade :opacity])]
    (animation/set-value @bottom-fade-val current-opacity)
    db))

So everytime a animation is fired, I am saving the value of that animation in the db (fade-to 1) saving 1 but leaving the actual object be some global variable. Hmm ;x
