Rafa_F · August 12, 2015, 8:21pm

0.4.1 (2015-08-12)

New Feature: Coroutine based socket supports unix domain socket
New Feature: APIs for Embedding Nginx-Clojure into a standard
Clojure/Java/Groovy App (issue #86). This feature makes debug/test with
Nginx Clojure/Java/Groovy handlers very easy.
New Feature: Autodetect jvm_path (issue #85)
New Feature: Support to use annotation to mark a class or method to be
suspenable in coroutine context (issue #84)
Enhancement: Auto send error when meets a non websocket request with
auto_upgrade_wsis on
Enhancement: Add websocket-upgrade! to server channel API
Enhancement: Add WholeMessageAdapter to make handling small websocket
messages easier.
Bug Fix: NginxHttpServerChannel.write(ByteBuffer buf) does not reset the
buffer’s position (issue #83)
Bug Fix: No access to tomcat server 8.24 from nginx-clojure (issue #82)
Binaries Distribution: Including some java sources for easy debug.
Build Script: Autodetect JNI header files

Below are some simple examples about embedding Nginx-Clojure and we can
try
them with lein repl or debug them in a Java IDE.

[nginx-clojure/nginx-clojure-embed “0.4.1”]

For Clojure

;;(1) Start it with ring handler and an options map
;;my-app can be a simple ring hanler or a compojure router.
(run-server my-app {:port 8080})

;;(2) Start it with a nginx.conf file
(run-server “/my-dir/nginx.conf”)

;;(3) Start it with a given work dir
(binding [nginx-work-dir my-work-dir]
(run-server …))

;;(4) Stop the server
(stop-server)

For Java

//Start it with ring handler and an options map
NginxEmbedServer.getServer().start(“my.HelloHandler”,
ArrayMap.create(“port”, “8081”));

//Start it with with a nginx.conf file
NginxEmbedServer.getServer().start(“/my-dir/nginx.conf”);

//Start it with a given work dir
NginxEmbedServer.getServer().setWorkDir(my-work-dir);
NginxEmbedServer.getServer().start(…);

//Stop the server
NginxEmbedServer.getServer().stop();
default options:

      "error-log", "logs/error.log",
      "max-connections", "1024",
      "access-log", "off",
      "keepalive-timeout", "65",
      "max-threads", "8",
      "host", "0.0.0.0",
      "port", "8080",

There 's an example about compojure routing and websocket example in the
unit tests source :

Clojure:

        [nginx.clojure.embed]

  (:require [compojure.core :as comp :refer (defroutes GET POST)])
  (:require [clj-http.client :as client]
            [gniazdo.core :as ws]))

(defroutes my-app
  (GET "/hello" req {:status 200 :body "Hello, Nginx & Clojure!"})
  (GET "/websocket-echo" req 
       (let [ch (hijack! req true)]
          (when (websocket-upgrade! ch true)
            (add-listener! 
             ch 
             {:on-open (fn [ch] (println "on-open!"))
              :on-message (fn [ch msg rem?] 
                            (println "on-message:" msg) 
                            (send! ch msg (not rem?) false))
              :on-close (fn [ch reason] (println "on-close:" reason))
