clojurescript-openwhisk

Making it easier to write OpenWhisk functions using ClojureScript

Background

This is a very small library that is intended to do two things:

1. wrap your ClojureScript code, so that it can be executed in OpenWhisk's Node.js runtime
2. make some of the functions of the OpenWhisk npm package available in ClojureScript

Installing

[trieloff/clojurescript-openwhisk "0.1.1"]

(:require [openwhisk.wrap :as o])

Usage

(defn echo [params]
  (identity params))

(o/wrapfn echo)

Building with Leiningen

(defproject myproject "0.1.0-SNAPSHOT"
  :dependencies [[org.clojure/clojurescript "1.9.521" :exclusions [org.apache.ant/ant]]
                 [trieloff/clojurescript-openwhisk "0.1.0"]
                 [org.clojure/clojure "1.8.0"]]
  :plugins [[lein-cljsbuild "1.1.6"]]
  :clean-targets ^{:protect false} ["target", "main.js"]
  :hooks [leiningen.cljsbuild]
  :cljsbuild {
    :builds [{:id "server"
              :source-paths ["src/cljs"]
              :jar true
              :compiler {:main mypriject.core
                         :output-to "main.js"
                         :language-in  :ecmascript5
                         :language-out :ecmascript5
                         :pretty-print true
                         :closure-output-charset "US-ASCII"
                         :hashbang false
                         :optimizations :simple ;; notice this!
                         :target :nodejs }}]})

Then run lein compile to build, and deploy the resulting main.js to OpenWhisk.

The :closure-output-charset is set to "US-ASCII" to work around an encoding shortcut in the Google Closure compiler that is causing interoperability challenges in OpenWhisk.
