Hi,
Following code cause an error, because NodeList doesn't extend
ISeqable.
(doseq [u (goog.dom/getElementsByClass "myclass")]
...)
Uncaught Error: No protocol method ISeqable.-seq defined for type
object: [object NodeList]
So I implemented ISeqable for NodeList.

You'd want to use one of the insert functions for that:

(sql/with-connection db

So there's pinot, but I've come to a relatively similar conclusion to

There are several JavaScript libraries that can probably be wrapped,
but a ClojureScript library should be great. I noticed a short
