http.async.client - Asynchronous HTTP Client - Clojure
http.async.client is the Asynchronous HTTP Client for Clojure. It is promise-based and uses the Asynchronous Http Client for Java for the heavy lifting.
All released artifacts are deployed to Clojars.
TravisCI is used to track the build status of intermediate commits on the following branches:
Declare dependency (using leiningen, in this example):
(defproject your-project "1.0.0-SNAPSHOT" :description "Your project description" :dependencies [[org.clojure/clojure "1.10.0"] [http.async.client "1.3.1"]])
Asynchronous GET request
(ns async-get (:require [http.async.client :as http])) (with-open [client (http/create-client)] (let [response (http/GET client "https://github.com/cch1/http.async.client/")] (-> response http/await http/string)))
(ns ws-client (:require [http.async.client :as http])) (def url "ws://remote-websocket-url:1337") (defn on-open [ws] (println "Connected to WebSocket.")) (defn on-close [ws code reason] (println "Connection to WebSocket closed.\n" (format "[%s] %s" code reason))) (defn on-error [ws e] (println "ERROR:" e)) (defn handle-message [ws msg] (prn "got message:" msg)) (defn -main  (println "Connecting...") (with-open [client (http/create-client)] (let [ws (http/websocket client url :open on-open :close on-close :error on-error :text handle-message)] ; this loop-recur is here as a placeholder to keep the process ; from ending, so that the message-handling function will continue to ; print messages to STDOUT until Ctrl-C is pressed (loop  (recur)))))
It runs with Clojure 1.5.1, 1.6.0, 1.7.0, 1.8.0, 1.9.0 and 1.10.0. Development is against Clojure 1.9.0.
