comp-middleware^cljs

(comp-middleware v)

Given a vector of middleware, filter out any nils, and use "comp" to compose the elements. v can have nested vectors, and will be flattended before "comp" is applied. For convienience, if v a function (assumed to be middleware already), just return it. Filtering out nils allows us to create Middlewhere conditionally like this: (comp-middleware [pure (when debug? debug)]) ;; that 'when' might leave a nil

handle^cljs

(handle event-v)

Given an event vector, look up the handler, then call it. By default, handlers are not assumed to be pure. They are called with two paramters:

the app-db atom and
the event vector The handler is assumed to side-effect on the given atom, the return value is ignored. To write pure handlers, use the "pure" middleware when registering the handler.

(register-base event-id handler-fn)

(register-base event-id middleware handler-fn)

register a handler for an event. This is low level and it is expected that "register-handler" would generally be used, see re-frame.core.
