I am trying to port a lib and in Clojure the author extends clojure.lang.Seqable. What would be the equivalent in Cljs?

ISeqable would not work because it is a protocol and I don't think I can extend a protocol in cljs? not sure though

I guess my question is similar to this one: https://stackoverflow.com/questions/34700857/how-to-extend-protocols-to-clojurescript-collections-generically#34701074

what does the :externs ["react/externs/react.js"] in lein's project.clj clojurescript compiler options when using reagent do? I can't find it being documented somewhere

I understand what :externs does, I just don't understand where the "react/externs/react.js" path comes from

:externs point to a file that allows the closure google compiler to figure out what it can and cannot prune when doing an advanced compilation

it's usually pointing relative to the resource-path(?)

It could be wrt to the asset-path, I can't remember

maybe someone else can confirm

yeah it's the classpath & current dir

Do any existing clojurescript documentation generators support reading from the compiled code? I am playing around with creating a cljs aws sdk (á la amazonica, but using node underneath) which generates a ton of functions dynamically.
