is there a library for state management along the lines of reagent/re-frame without the UI pieces?

Some folks at nilenso wrote this small lib recently: https://github.com/nilenso/wscljs. Thoughts?

I spent the night trying to figure out how cross-module code motion works with cljs 1.9.908 but I can't solve my problem and need some help. I have a simple build with two modules as in :

{:output-dir    "resources/public/js/out"
 :asset-path    "/js/out"
 :optimizations :whitespace
 :modules        {:core  {:entries   #{app.core}
                          :output-to "resources/public/js/out/core.js"}
                  :pages {:entries   #{app.pages}
                          :output-to "resources/public/js/out/pages.js"}}}

does defmethod belong in the clj portion of the code or the cljs?

I think it depends

so confusing

@gfredericks if I understand your question correctly, you can use defmulti/`defmethod` both in clj and cljs. It works the same way. What do you find confusing in this feature ?

@ggaillard I'm dealing with something more subtle. If I understand it correctly, cljs.test/assert-expr is a clj multimethod, so it has to be extended from clj code in the same place that you put macros. And this is problematic for a cljc project where you can't assume cljs.test exists

I think I fixed it with dynamicity, but it's unfortunate to have to resort to that

:thinking_face: indeed. cljs.test/assert-expr is defined in a cljc file, it will be expanded during the compilation phase (phase 1, clojure side) into cljs code that will then be compiled to js (phase 2). If you try to implement macros on top of it you can put them in a cljc file and use reader conditionals #?{:clj …, :cljs …}. This way you can ensure that cljs.test exist.

I don't think reader conditionals works

you have to put everything in the :clj side

to be clear my code has (defmethod cljs.test/assert-expr ...) in it, and that needs to go on the :clj side

I think this is the same as the more traditional problem of macros that are sensitive to which environment you're in

but apparently requires more tricks to solve
