are there any examples of adding watchers to clojurescript mount state?

I'm getting the following error: could not start [#'app.example/config] due to Error: No protocol method IWatchable.-add-watch defined for type mount.core/DerefableState: [object Object]

whereas the clojurescript readme has the following line: States may have watchers which is just an idea at this point, but it could be quite useful

here https://github.com/tolitius/mount/blob/master/doc/clojurescript.md#managing-state-in-clojurescript

@jiangts: when looking at the source, I think it is not implemented yet?

I see: looks like mount states aren't plain old atoms?

You could hack it yourself, by adding a watcher on @#'mount.core/meta-state, or on (-> @#'mount.core/meta-state (.name your-derefable-state) :inst)

@jiangts: true, though it does use plain old atoms in its implementation 🙂

But, maybe @tolitius wants to add "official" support for this 🙂

that'd be preferable, but I'll use the workaround for now. Thanks!

@jiangts: not sure if the workaround works in CLJS though, so I am curious to know your results 🙂

it worked! The representation of @#'mount.core/meta-state is slightly different in clojurescript (so I need to dereference it yet again), but otherwise it works 🙂 Thanks!

Nice!
