Sorry for the delay @thheller! http://shadow-cljs.org/ -> Beginner Guide (== https://medium.com/@jiyinyiyong/a-beginner-guide-to-compile-clojurescript-with-shadow-cljs-26369190b786)

hi, I'm trying to setup code splitting with below config. I have app.main which is an spa router and 2 pages (home & todo)

:modules {:shared {}
                          :main {:entries [app.main]
                                 :depends-on #{:home :todo}}
                          :home {:entries [app.pages.home]}
                          :todo {:entries [app.pages.todo]}}

@gnhuy91 you need to specify a shared module. so its probably the reverse. :home depends-on #{:main} as well as todo depends on #{:main}

app.main will always be loaded and home and todo on demand. so they depend on :main

arh thanks! so I misunderstood it there 👌

hi, on "loading code dynamically", how can I access to the loaded module? (loader/load "extra") resolver only indicate loaded/failed status and does not return the module itself. (in webpack it is import(() => "./foo").then(foo => foo.default))

well thats where it gets a bit tricky

the namespaces that are part of the module you loaded are accessible

but the compiler doesn't handle this very nicely

you can use resolve to get to a function you defined

((resolve 'your.ns/foo) 1 2 3)

would basically call (your.ns/foo 1 2 3)

let me try, thanks!

mindblow 🤯 , it works

more tricky than i thought, was building a loadable component wrapper to handle dynamic rum components

thank alots 🙏

yeah closure handles modules statically so it works a bit differently than in webpack

is there any analyzer metadata I can get out of a bootstrapped environment?

I’m trying to get line number and position of a particular token (e.g. a path into a map)

you can modify cljs.tools.reader to do what you need

it doesn't keep line/col metadata on keywords by default

does it keep line/col metadata on other values?

edn reader no. cljs reader yes

not on keywords, numbers, strings, bools

maybe this helps. I tried something related a while ago https://dev.clojure.org/jira/browse/TRDR-42

:thinking_face: is there something I’m doing wrong here?

(-> (reader/read-string "{:foo 5
                          :bar [1 2 3]}")
    (meta))

you are using the EDN reader

(require ...
            [cljs.tools.reader :as reader])
