has anyone used crdt data types in cljs?


i’m considering using in a project but not sure how much of a pain it would be mixing these data structures


Have not used it myself, but this is related and may be useful:


Hi everybody! Maybe this has been already asked but, has anybody managed to use vim-fireplace with clojurescript? I’ve been trying with shadow-cljs and figwheel but got no luck 😞

I feel your pain. Not with that specifically but I feel like most people after trial and error find some setup that works and then just stick with that for about 5ish years at least haha. I know I should probably switch to shadow-cljs but I only figured out how to use figwheel-main with emacs after several months of trial/effort lol

With shadow, if you are running the dev server you can :Connect to the port it starts the nrepl server on, and then :Piggieback {your shadow app name} to it after that. Not ideal but does work


I tried that, I have ran shadow-cljs watch app and in vim I run the :Connect 3333: (nrepl port is configured to be the 3333), after that I do the`Piggieback :app` and I get “No application has connected to the REPL server. Make sure your JS environment has loaded your compiled ClojureScript code.”


My shadow-cljs.edn file looks like this:

{:source-paths ["src"]
 :dependencies [[cider/cider-nrepl "0.21.1"]]
 :nrepl {:port 3333}
 :dev-http {8080 "resources/public/"}
 :builds {:app {:target :browser
                :output-dir "target/browser"
                :modules {:main {:init-fn example.core/main!}}
                :devtools {:after-load example.core/reload!}}}}

are you loading the app in your browser?


It was a lein figwheel initialized project which I was trying on. I created an example app using npx create-cljs-project and got it easily working as you stated. Thanks a lot @UMP2T9H7Y

Does anyone have a recommendation to an automated testing alternative to lein doo (using deps.edn and/or shadow-cljs)?

Lone Ranger14:02:32

(preferably deps.edn cause I haven't learned shadow-cljs yet :face_with_rolling_eyes: )


what kind of app are you testing?

Lone Ranger14:02:38

but not the components, just regular clojurescript functions

Lone Ranger14:02:04

I've been running tests from repl/browser and that's fine but want to get a ci/cd thing going. Travis or the like

Lone Ranger14:02:32

will use lein doo if necessary but I've been enjoying the minimalism of deps.edn


kinda in the same boat myself, been looking at lein doo for integration testing of a re-frame app as well


though I like cljs-test-display and might just use that along with re-frame-test for the clojurescript stuff


mostly just testing event handlers and want to quickly inspect the feedback

Lone Ranger14:02:55

ok great I'll check that out

Lone Ranger14:02:07

yeah I hear ya


also check out figwheel-main's testing features


i haven't started using figwheel main in my apps yet due to some problems with legacy setup, but it has provisions for integrations CLJS tests to CI

Lone Ranger14:02:41

out of curiosity is it an issue converting project.clj to deps.edn?


It depends on how much you're relying on lein features

Lone Ranger14:02:21

true, lein has a lot of good features that it's hard to get away from. I still use it for library projects because it's great for shipping
