Hi Aaron,
I took this idea from yogthos blog and the whole session namespace contains an
freactive atom plus some helpers:
(ns de.sveri.dockerui.session
(:refer-clojure :exclude [get])
(:require [freactive.core :refer [atom]]))
(def state (atom {}))
(defn get [k & [default]]
(clojure.core/get @state k default))
(defn put! [k v]
(swap! state assoc k v))
(defn update-in! [ks f & args]
(clojure.core/swap!
state
#(apply (partial update-in % ks f) args)))
So I am assuming that I can nest (rx ...) calls and only the part that changes
will get updated. Is that right?
This is basically what I am trying to achieve right now.
Best Regards,
Sven
