Is it ok to read component's arguments in a trait? How can I idiomatically extract them from a state?
cheatex 2018-12-07T08:19:50.013700Z
I've ended up having few helper functions looking like:
(defn focus-when-selected [{args :rum/args :as state}]
(let [[item _] args]
(when (:selected item)
(.focus (rum/ref-node state ::name-input))))
state)
cheatex 2018-12-07T08:20:51.014300Z
use them like
(rum/defcs edit-c <
{ :did-mount focus-when-selected,
:did-update focus-when-selected }
[state item actions]

A quick improvement idea. Emit warning when a trait function returns nil

hello guys! i'am pretty new to rum 🙂 I tried using cursors and found that view (rum/static, rum/reactive) seems not to be updated when i modify meta of cursor data with vary-meta. is it ok? or what am i doing wrong?

i am trying to use meta data to store things like loading and error flags, etc.

you shouldn't be using metadata for that.
2018-12-08T16:19:11.020400Z
why not?
2018-12-08T16:21:58.020600Z
it's convinient to put such things in meta other then have tree like {:users {:data [...], :loading? false, has-more? true}}. Does not it?

If your UI cares about those things, that's a sign to me that it should be data, not metadata. I find it's better to avoid using metadata unless you're doing some crazy macro stuff.

makes sense
