Auto building Clojurescript files for Compojure app - clojure

Question

I have a web application where i'm using Compojure on the server and Clojurescript on the client. I'm using the leing-cljsbuild plugin to automatically compile cljs files to js.
I'm able to generate the required client side files and load them in the browser when I set the optimizations to :whitespace or :simple, but when I set optimizations to none, the js files reference their dependencies using the local file-system path, which leads to the files not loading at all in the browser.
So, my question is how do I make the generated files use server urls instead of local file paths when they are generated by the clojurescript compiler.
Here's my project.clj file
(defproject my-proj-clj "0.1.0-SNAPSHOT"
:description "FIXME: write description"
:url "http://example.com/FIXME"
:dependencies [[org.clojure/clojure "1.5.1"]
[compojure "1.1.6"]
[org.clojure/tools.nrepl "0.2.3"]
[hiccup "1.0.3"]
[com.novemberain/monger "1.5.0"]
[org.clojure/clojurescript "0.0-2127"]
[jayq "2.5.0"]
]
:plugins [[lein-ring "0.8.8"]
[lein-cljsbuild "1.0.1"]
]
:ring {:handler my-proj-clj.handler/app
}
:cljsbuild { :builds
[{
:source-paths ["src/my-proj-clj"]
:compiler {
:output-dir "./resources/public/js"
:output-to "./resources/public/js/cljs-file.js"
:pretty-print true
:source-map "./resources/public/js/cljs-file.js.map"
:optimizations :none
}}]}
:profiles {:dev {:dependencies [[javax.servlet/servlet-api "2.5"]]}}

Answer 1

I believe the only valid optimization values are :whitespace, :simple, or :advanced. See line 96 at https://github.com/emezeske/lein-cljsbuild/blob/1.0.1/sample.project.clj.
Thus I would use :whitespace as the optimization level (at least to get something working).
Per your post, an optimization level of :whitespace works? Thus, perhaps you can elaborate.
What results are you expecting from an optimization level of ":none". How does your expected result differ from what an optimization level of :whitespace produces?
An optimization level of :none means cljsbuild is not generating js from your cljs source (it will generate a few goog.include statements but nothing else). Try using an interactive repl to help you prototype. Try running the following : lein trampoline cljsbuild repl-rhino
Hope that helps.

I have roughly same setup, optimizations set to :none, generated files use local paths. However, browser does load the scripts.
What I have is this in index.html:
<script src="js/development/goog/base.js" type="text/javascript"></script>
<script src="js/development/main.js" type="text/javascript" ></script>
<script type="text/javascript">goog.require("ixtlan.core");</script>
this in project.clj:
:cljsbuild {
:builds [{:id "dev"
:source-paths ["src/cljs"]
:compiler {
:output-to "resources/public/js/development/main.js"
:output-dir "resources/public/js/development"
:optimizations :none
:source-map true}}
...
and routes contain:
(defroutes routes
(GET "/" [] (index))
(route/files "/" {:root "resources/public"}))
Hope, this helps.
