diane

Server-Side Server-Sent-Event client

Why call it diane?

Because the alternative was server-side-server-sent-event-client, or sssse, or s4e, or some such other terrible name.

Usage

• API Docs

My use case for writing this was to get events from my Spark Core on the server side (this was before they added the functionality to call an arbitrary url when an event is sent):

(require '[clojure.core.async :refer [<!!]])
(require '[diane.client :refer [subscribe]])

(def access-token "xxxxxxxxx")

(let [[events state close] (subscribe "https://api.spark.io/v1/events"
                            {:headers {"Authorization" (str "Bearer " access-token)}})]
  (println (<!! events))
  (println (<!! events))
  (println (<!! events))
  :etc
  (println "Connection state:" (:ready-state @state))
  (println "Reconnection time (in ms):" (:reconnection-time @state))  ;; See client.clj for other state
  (close))

;; Connection state: :open
;; Reconnection time (in ms): 3000
;; {:origin "https://api.spark.io/v1/events, :data  "event data!", :event "an-event-type", :last-event-id  ""}
;; {:origin "https://api.spark.io/v1/events, :data  "more event data!", :event "another-event-type", :last-event-id  ""}
;; {:origin "https://api.spark.io/v1/events, :data  "event data again!", :event "yet-another-event-type", :last-event-id  ""}
