Hello There, I have a quick question, I am new in clojure How do I use png file in cljs? I have a shadow cljs application for example "./icons/marker.png I’ve tried using this but it’s not loading

how are you embedding it? this is not a CLJS question really, more HTML specific. if you use ./ in the path it'll be relative to the page you are on. you need to make sure the path is correct.

Hi, how can I name the file something other than main.js?

this caught me too, the key in the map decides

Aha

thank you @ashnur

Hi there. Is it possible to invalidate the node_modules cache without restarting npx shadow-cljs watch app ? Any option?

invalidate why? I mean what do you expect that to achieve?

I put some console.log on npm package for debugging.

you can touch node_modules/that-package/package.json to trigger a recompile

I don't have any output, so I supposed that's because Shadow cache.

Oh perfect, thx!

yeah I removed individual file watching for node_modules files because some projects used like 5000 files from there and that was causing some performance issues

but it still watches package.json files in cause you npm install stuff or so

touching the package.json will invalidate the entire package

Yeah I understand, very good reason performance wise. Thanks Thomas.

Is there a reason I should defonce my app-db in a re-frame project from a hot-reload perspective?

yes, without it the hot-reload will just replace it with a new atom when you modify the file

defonce is needed if you want to keep your state

The state seems to be kept in the re-frame.db/app-db ratom. I notice no difference when I use def on my app-db. hot reload seems to work the same.

then I don't understand your question. when using re-frame you don't have your own app-db?

I am asking because I am going to present ClojureScript app development on a meetup Wednesday. And I had sort of planned to mention defonce as a protector of the app-db, but when I tested it I noticed that that part of the demo doesn’t seem to hold. Looking in re-frame.db then, it’s app-db is also just (def app-db (ratom {})) . I just want to understand a bit better how it really works. Even if I realize I should stay away from the subject during the demo. 😃

well you don't modify the re-frame.db namespace so it is never reloaded and never has this issue

Ah. Thanks!

if you have this is your main namespaces that is constantly getting reloaded you will lose your state every time without defonce 😉

Yeah, I can totally get it to happen with a local atom and such. Which added to my confusion.
