I’ve been trying to make a devcard for an Om component, but it requires a target element. I’ve tried to use the dom-node macro. Anybody know how to pass it to Om? Here’s my code: (defcard-om campaign-countdown (om/root timer/countdown-timer timer-state {:target (dom-node)}))

@sventechie: Hi Sven, see this:

(defcard
    (om/mock-root reconciler YourDataScriptBackedComponent))

Another example, less powerful:

(def input-nam-letters (om/factory InputNamLetters))

(defcard
  (fn [init-data _]
    (input-nam-letters @init-data))
  {:nam-letters "Blah"}
  {:inspect-data true
   :history true})

Hmm, I still get the error: "Card has not mounted DOM node."

In both cases I didn't need to pass the target node (but I may have misundestood your need on that level)

What version of devcards?

Mine: 0.2.1-2

OK, looks like maybe you’re using om.next?

oh, yes, sorry! And I never used Om.current

I’m trying to integrate this example countdown timer: http://madhuvishy.in/posts/2014/04/devlog-week-9-getting-started-with-om.html

I’d be happy to port it to om.next but not sure how involved that’d be.

Here’s the source: https://github.com/madhuvishy/cheating-countdown/blob/master/src/cheating_countdown/core.cljs

ok, then try

(defcard-om campaign-countdown
            (fn [init-data node]
              (om/root timer/countdown-timer timer-state
                       {:target node})))

Also look at Bruce's examples: https://github.com/bhauman/devcards/blob/master/example_src/devdemos/om.cljs http://rigsomelight.com/devcards/#!/devdemos.om

Yeah, I looked at Bruce’s examples but he never uses the macros I think I’d need.

I’m still getting "Card has not mounted DOM node.” with your example.

Where did you get the argument list?

Found it back from the github repo's README: http://rigsomelight.com/devcards/#!/devdemos.defcard_api

Also check the bottom of the page.

Hmm, thanks, Google searches did not turn up those documents.

node appears to be a React element, rather than a DOM element. I wonder if that’s a problem.

ok so the bottom of that page will tell you how to reach a DOM element.

Note: I haven't looked at if you really need the low-level of a DOM element for that counter.

Thanks! I’m asking the more general question in the #om channel now.

No problem!
