When I run (js/require "") in repl terminal I see next error:

repl/invoke error, [ReferenceError: Can't find variable: require]
- node_modules\react-native\Libraries\YellowBox\YellowBox.js:59:8 in error

require is a compile-time construct in react-native. it is not a function you can call at runtime, so it cannot be used from the REPL

Is there other way to require file?

just don't do it at the REPL. it works in regularly compiled files that react-native metro has processed

Aha so lets say a user will paste url to my app, and I create next function:

(defn download [url] (js/require url))

no

use js/fetch for that

or whatever react-native has for network requests. I don't develop react-native apps so I'm not actually sure

okay thank you, I forgot about fetch

Another thing which I don't understand is why do I have error when I try to load audio from a URL. I use expo-va and my code is pretty simple:

(ns example.views.notification
  (:require
   ["expo" :as ex]
   ["react-native" :as rn]
   ["expo-file-system" :as fs]
   ["expo-asset" :refer (Asset)]
   ["expo-av" :refer (Audio)]))

(defn test []
(.catch (.then (.createAsync (.-Sound Audio) {:uri ""})(fn [x] (prn "Loaded"))) #(prn % " error")))

#object[Error Error: Cannot load an AV asset from a null playback source] " error"

Couod it be because the map with uri in need to be a js object

#js {:uri "..."}

@danieleneal yeah I was thinking about same issue, I'll try to use #js {:uri "..."} tomorrow, thank you
