node-signal clj/s

(node-signal {:keys [context graph initial-graph]} node-key signal-key)

Trigger a signal through a node, assumes dependencies have been run. Subsequent signal calls is supported, but it should be handled in it's implementation. For example, http server component checks that it already started and does nothing to prevent port taken error or it can restart itself by taking recalculated properties from deps. Static nodes just recalculates its values. If node does not support signal then do nothing.

normalize clj/s

(normalize {:keys [context graph initial-graph]
            :or {context default-context}
            :as gx-map})

Given a graph definition and config, return a normalised form. Idempotent. This acts as the static analysis step of the graph. Returns tuple of error explanation (if any) and normamized graph.

normalize-node-def clj/s

(normalize-node-def {:keys [context initial-graph]} node-key node-definition)

Given a component definition,

normalize-signal-def clj/s

(normalize-signal-def signal-def)

selector-with-deps clj/s

(selector-with-deps {:keys [graph context] :as gx-map} signal-key node-key)

Returns a node with its dependencies as a list of keys for a specific selector (signal-key + node-key)

signal clj/s

(signal gx-map signal-key)

(signal gx-map signal-key selector)

Send signal to the graph or to its subset if selectors are passed. Selectors is a set of top level graph keys, signal will be executed on selectors and its dependencies according to signal ordering.

states clj/s

(states gx-map)

topo-sort clj/s

(topo-sort {:keys [context graph]} signal-key)

Sorts graph nodes according to signal ordering, returns vector of [error, sorted-nodes]

validate-props clj/s

(validate-props schema props)

values clj/s

(values gx-map)

with-context-failures clj/s

(with-context-failures {:keys [context] :as gx-map})

Validates context against schema and checks signal dependency errors
