(<sub app query)

Subscribe and deref a subscription, returning its value, not a reaction.

cache-lookup clj/s

(cache-lookup datasource cache-key)

clear-handlers clj/s

(clear-handlers _db)

(clear-handlers _db id)

clear-sub clj/s

(clear-sub registry query-id)

clear-subscription-cache! clj/s

(clear-subscription-cache! registry)

Removes all subscriptions from the cache.

deflayer2-sub clj macro

(deflayer2-sub meta-sub-kw sub-name ?path)

Only supports use cases where your datasource is a hashmap.

Takes a symbol for a subscription name and a way to derive a path in your datasource hashmap. Returns a function subscription which itself returns a Reagent RCursor. Supports a vector path, a single keyword, or a function which takes the arguments map passed to subscribe and must return a path vector to use as an RCursor path.

Examples:

(deflayer2-sub my-subscription :a-path-in-your-db)

(deflayer2-sub my-subscription [:a-path-in-your-db])

(deflayer2-sub my-subscription (fn [sub-args-map] [:a-key (:some-val sub-args-map])))

sub-fn clj/s

(sub-fn meta-fn-key f)

Takes a function that returns either a Reaction or RCursor. Returns a function that when invoked delegates to f and derefs its output. The returned function can be used in subscriptions.

(subs-state-path k)

subscribe clj/s

(subscribe app query)

Given a query vector, returns a Reagent reaction which will, over time, reactively deliver a stream of values. Also known as a Signal.

To obtain the current value from the Signal, it must be dereferenced
