I've found this troublesome too when starting out. The compiler does catch the obvious cases but there's still many that slip through. I found that I'm more careful now and overall don't find it too troublesome anymore. I guess you just get used to it. It would be nice if the compiler could warn

Re: [ClojureScript] (newbie) om - clarity question: do I need to unsubscribe async channels?

Yes, you should terminate the go block in will-unmont, otherwise if your component is mounted multiple times, you will end up with multiple go blocks consuming from the channel. If you are transacting on a cursor, then this will just eat up resources, but if you are accessing owner (eg to get/set

Re: [ClojureScript] Best way to structure components in Om

I personally like keeping the incidental local state local to components and keep the app state purely for domain data. Therefore I would use the local state like you said and use the cursor only to point at the tag list being modified. As for how to manage the local state with sub components,

Re: [ClojureScript] Om / React : preserving identity across renders with key

:key is a keyword which is used to look up app state (as pointed to by the cursor passed to build) and the value found there is then used as the react key. :react-key is a value (eg a string) which is used as the react key directly. For example: (om/build my-component {:foo hello} {:key :foo})

Re: [ClojureScript] [Om] TodoMVC question

You can put seqs in IFF you don't rely on them being cursors later. I find it easier and safer to make sure they're always cursors. A place this has caught me out is transferring seqs over Websocket and putting them in app state. Now I always call vec (or use mapv or other alternatives as

Re: [ClojureScript] Can I make any updates to a Clojurescript Om component in the InitState?

I personally avoid doing anything impure in IInitState. To me it seems that it should be a pure function returning a map of the local state. IWillMount is a better place to do things. Could you perform the updates in the parent? On 5 September 2014 10:23, Zubair Quraishi zuba...@gmail.com

Re: [ClojureScript] Consequences of not closing channels in browser?

Daniel. I can confirm that cljs.core.async.impl.channels.ManyToManyChannel.closed gets set to true after my component is unmounted and (! subscriber-ch)subsequently returns nil, so it looks to be working as expected! Cheers, Dhruv Bhatia On Aug 31, 2014, at 8:48 PM, Daniel Kersten dkers
