The browser devtools should reload it for you automagically when it changes on disk, if you use the built-in server and whatnot
I know how to configure a build with my own index.html that includes my CSS. I would like to avoid that for a simple project, and just include the CSS in the default browser REPL page
I see. Seemingly, it won't know if files on disk has changed unless you have some devtool connection between the browser and the clojure process that shadow-cljs runs its builds from. Would be a lot of additional setup to get that running.
You could manually remove/add link
tags in your DOM I guess and point it to the CSS file on disk, trigger that action on change somehow
I don't think you need any fancy "hot reload" but can simply reload the entire file at once without any concern
I wonder how shadow-cljs reloads the CSS. is it just adding/removing the link tags?
yes, looking for link tags and replacing them https://github.com/thheller/shadow-cljs/blob/e9093aed586d5fb49efd94555787f0bef08fb164/src/main/shadow/cljs/devtools/client/browser.cljs#L119-L147
but browser-repl is nothing but a regular :browser
build so technically it would be easy to add. there just aren't any options for it
