Any particular reason for using cljsjs? I know shadow-cljs allows you to directly consume npm libraries and I thought other cljs build tools did too.

Pretty new to cljs, so there is no clear reason. I'll try shadow-clj. Thank for the help :))

Regular JS interop. (.then promise (fn [result] ...)) and all that.

okay

the problem i'm facing is sequence of promises

You haven't really described the problem. What are you trying to do?

i have a vector with objects which describes an http request

i want to execute them serially

Create a function that calls (.then response-promise (fn [result] ...)) and calls itself with (next parameters) somewhere in the ....

Maybe Promesa has something specifically for this scenario, I don't know. I would still use regular interop.

okay, well promesa seems to tidy things a bit

I use this https://github.com/athos/kitchen-async

This worked for me:

(:require
    [cljs.core.async :refer [go]]
    [cljs.core.async.interop :refer-macros [<p!]])


(go
      ; wait for the promise to complete before continuing
      (let [result (<p! (fn-returns-a-promise))]
        (println "Result" result)
        (do-next-thing))
      )

Thanks, I will check that.
