sse-fx

sse-fx provides a set of re-frame fx and cofx handlers for working with EventSource objects and Server-Sent Events.

Usage

(ns re-frame-app.events
  (:require [re-frame.core :as re-frame]
            [com.yetanalytics.sse-fx.events :refer [register-all!]]
            [com.yetanalytics.sse-fx.event-source :as event-source]
            ))

;; Register all fx/cofx
(register-all!)

;; Just the event source handlers
;; (event-source/register!)

;; Use one in a handler
(re-frame/reg-event-fx
 ::init-event-source
 (fn [{:keys [db] :as ctx} _]
   {::event-source/init
    {:uri "/query"
     ;; handle-* args are re-frame event handlers
     :handle-open [::sse-open] ;; re-frame app handler to dispatch
     ;; messages are transit-decoded by default
     ;; supply your own with :decode-msg-fn
     :handle-message [::sse-message]
     ;; Errors can be actual EventSource errors, or handling/dispatch errors.
     ;; either way, they're wrapped in an ex-info
     :handle-error [::sse-error]
     ;; This isn't an event, but rather fires when you close the EventSource with the ::event-source/close fx handler
     :handle-close [::sse-close]}}))
