I am trying to use a npm package in cljs called "https://github.com/sebhildebrandt/systeminformation" most of its function are async and some are non-async but I am unable to use async function, everything else work fine
RELATED IMPORTS
[clojure.core.async :as async]
["systeminformation" :as systeminformation]
Code I am trying to run
(comment
(systeminformation/version) // WORKS FINE
(async/go
(async/<! (systeminformation/cpu))) // Gives me error
)
ERROR:

Async functions from javascript are functions which return a javascript Promise.
async.core
would require a clojurescript core.async channel to work.
With promises you can work as normally with js promises or use a helper library like https://github.com/funcool/promesa
yes but I wanted to avoid any library use this works too:
(.then (js/Promise.resolve (systeminformation/cpu))
#(log/spy (js->clj %)))
Why do you use .resolve? Unwrap the call to
(.../cpu)`.
(-> (systeminformation/cpu) (.then (fn [result] ...)))
