clj-socko

A Clojure wrapper for the Akka-based Socko web server.
Uses Okku as the Akka wrapper.

Streaming and websocket coming soon.

Usage

Basic Ring serving:

(ns your.app
  (:use clj-socko.core))

(defn app [req]
  {:status 200
   :headers {"Content-Type" "application/json"}
   :body "{\"hello\": \"world\"}"})

(run-server {:http (actor-handler (ring-actor app))} {:port 8080})

With some routing:

(ns your.app
  (:use clj-socko.core))

(defn app-one [req]
  {:status 200
   :headers {"Content-Type" "text/plain"}
   :body "Hello World"})

(defn app-two [req]
  {:status 200
   :headers {"Content-Type" "text/plain"}
   :body "Hello POST"})

(defn not-found [req]
  {:status 404
   :headers {"Content-Type" "text/plain"}
   :body "Not found"})

(run-server
  {:http (cond-handler
           (every-pred get?  (path "/hello")) (ring-actor app-one)
           (every-pred post? (path "/testpost")) (ring-actor app-two)
           not-found? (ring-actor not-found))}
  {:port 8080})

This example routes GET /hello to app-one, POST /testpost to app-two, everything else to not-found.

cond-handler performs cond matching before sending the message to the actor. That means you can route requests to non-Clojure actors. clj-socko expects Props of the actor, not the class.

every-pred is a standard Clojure function. not-found? is a predicate that always returns true, no magic there.

Note: you shouldn't use this as your app's main routing thing. Leave that to server-independent libraries like Compojure. But this is useful for eg. routing static file requests to Socko's StaticContentHandler.

Performance

On a completely unrealistic benchmark (instantly return a response), 2x slower than http-kit. On a more realistic benchmark ((Thread/sleep 75)), about the same.
