Ns form with imports work

(ns index
  (:require ["fs" :as fs]
            ["url" :refer [fileURLToPath]]))

(prn (subs (fs/readFileSync (fileURLToPath js/import.meta.url) "utf-8")
           0 100))

(defn foo [{:keys [a b c]}]
  (+ a b c))

(js/console.log (foo {:a 1 :b 2 :c 3}))

So one thing I'm contemplating: should functions with (defn foo ...) be automatically exported with:

export { foo }

set the channel topic: https://github.com/borkdude/cherry 🍒

how do js bundlers handle this? (this = renaming)

what renaming exactly?

how do they decide what names to keep stable and what to rename?

I think keeping the names is good for now, this probably compresses pretty well with gzip

oh that. I think once you are bundling, you can rename everything

since that's a final file

shouldn't matter right?

@mkvlr My thoughts weren't about renaming, it was about generating exports automatically for every defn, or only when marked as exported

I'll go with automatic for every defn for now

@borkdude what’s the export for?

isn’t that only for closure?

ES6 modules work with exports: you can't import what isn't exported

ah right

in js that’s explicit, right?

yes

automatic for public vars sounds like a good start

ok, export now working in version 0.0.0-alpha.17

(ns exports)

(def foo (fn [] "Hello"))

import { foo } from './exports.mjs';

console.log(foo());

I think we also need a way to do the default export, to be able to write this (bun) example:

export default {
  port: 3000,
  fetch(request) {
    return new Response("Welcome to Bun!");
  },
};

Not sure what syntax would be appropriate for that. Perhaps shadow-cljs already has something for this

Went with (def default ...) :)

I think a bun cherry run serve.cljs command would be good, which compiles + also runs
