see https://code.thheller.com/blog/shadow-cljs/2019/08/25/hot-reload-in-clojurescript.html

I did, but this is not explaining the interactions between reitit and reloading.

it probably is. see the gotchas?

most likely you are keeping some reitit state in your app db. ie. a render function, this function is not updated on hot-reload and as such you don't see any changes?

if you want to share some code I can probably point you to it

otherwise I'm just guessing

here is my example:

https://github.com/andrzejsliwa/shadow-cljs-tailwind/blob/main/src/main/app/routes.cljs

no matter if I define match state as defonce or def

where I’m changing some style in “interactive” view, changes are not reloaded, until I refresh browser manually

for example in this line https://github.com/andrzejsliwa/shadow-cljs-tailwind/blob/d516487b5c3b152fbef4e929a231b7d960e65c10/src/main/app/tailwind.cljs#L331

you can change class of color

when I’m rendering interactive component as root, everything working like expected, but when router is involved it’s not refreshing

you can also change the text in href or header

ok, I found it, the problem was that (router-start!) was in

(defn ^:export init
  []
  (router-start!)
  (start))

when I move it to

(defn ^:dev/after-load start
  []
  (router-start!)
  (d/render
   [current-page]
   (.getElementById js/document "app")))

then it’s working

thx @U05224H0W for pushing me in a good direction.

that is precisely the mentioned "Holding Code references in State" gotcha

you are putting function into a map, those functions are not updated by hot-reload

so you see old code, unless you re-create this map (which I assume the router-start! does
