Hello @U050986L9 Thanks for getting, I had solved that problem. I was getting nil as value for the following. I was just using (= feature.source "selected-item") so it turns out if supposed to be like (= (.-source ^js feature) "selected-item") I am JavaScript developer so I thought maybe we can use . in objects.

you can use libraries like https://github.com/applied-science/js-interop or https://github.com/binaryage/cljs-oops for cases like that

Thanks for sharing
