postgres-listener.core — de.hhu.cn/postgres-listener 0.2.1

Connect to a postgres-database and wait for a NOTIFY of the database. This notify-event triggers a function, which receives the payload as EDN if the payload was initially encoded as JSON (for example with postgres' function "row_to_json()".

arm-listener clj

(arm-listener f event)

Creates listener for new events in the eventstore. f/1 needs to be a function, which gets one parameter, which is the (transformed) payload published by postgres' trigger. And the event must match with the name of the trigger, e.g. "new_event".

For example: (arm-listener (fn [payload] (println payload)) "new_event")

connect clj

(connect {:keys [host port database user password]})
