1. Reactive db
db is atom there are views - (aka re-frame subs) as a pure function of paths in db
(defn my-sub
{:z/paths
{:user [:user],
:data [:my :data]}
:z/subs
{:osub #'other-sub}}
[state]
......)
There are db transaction effects like:
:assoc-in :dissoc :update-in
While zen applies transaction - it calculates which views may change and re-evaluate them.
For example we do tx assoc :key and re-evaluate views with paths [:key ...]
2. render layer
render is dumb - i.e. no calculations in render
(def my-page
{z/views {:key #'view}
z/render
{:tag :div
:text :view/key
:on-click :view/key
:child {:when :view/key :html :v/key}
:if?
:for-each?
}
)
