The second line is the Clojure declare usage:

(declare client send-message)

The on-connect function makes use of the send-message function before it is actually defined, so we do an ahead declaration so the Compiler does not complain about a missing symbol.

The rest of the code is now rather easy-going, so here comes the frontend.app namespace in full:

(ns frontend.app

(:require

[cljsjs.paho]

[frontend.utils :as utils]))

(declare client send-message)

(def topic "/cljsjs/paho")

(defn on-connect []

(println "Connected")

(.subscribe client topic #js {:qos 0})

(println "Subscribed")

(send-message "Hello MQTT!" topic 0)

(println "Sent message."))
