Support for nodejs

[rukor]

Is there planned support for cljs running under nodejs (in a server environment) ?

Thanks

[r0man]

No, noting planned. Patch welcome!

Thanks, I will take a look.

Assuming the presence of the "xmlhttprequest" NPM package (e.g. via lein-npm), then this works fine: https://gist.github.com/moea/63d7a882e4ad333f3b5a

Performing that kind of global adjustment is obviously a less-good idea in a library intended for reuse. If there was interest in including something similar, I think the lowest-impact approach would be to include an xhr-factory function, which takes in a function, and returns a class like the one linked above, with the input parameter serving as the implementation of the createInstance method. Additionally, requests could support something like a :cljs-http/xhr-factory key in request maps, which will pass the option to XhrIo. And/or a (cljs-http.core/set-xhr-factory!) function which sets the factory for all requests originating via cljs-http. The code for a Node user would be something like:

(require '[cljs.nodejs :as nodejs])
(require '[cljs-http.core :as http])

(def xhr (.-XMLHttpRequest (nodejs/require "xmlhttprequest"))

(http/set-xhr-factory! (http/xhr-factory #(xhr.)))

;; use library normally

Which isn't too bad, and doesn't require there to be anything vaguely Node-specific in cljs-http.

I would find an implemented version of this very useful as well. HTTP(S) + Node + CLJS seems like a pretty common/powerful usecase?

@vikeri Maybe this is helpful meanwhile https://github.com/nervous-systems/kvlt

I managed to get it working. But kvit seems to be a great project! I'm starting to work with React Native so this possibly comes in handy there :)
