Project organization and cljsbuild config to require namespace

Question

How do I organize my project structure and configure cljsbuild to require my own namespace? For example in my project/src-cljs folder I have:

└── project
    ├── file1
    │   └── file1.cljs
    ├── file2
    │   └── file2.cljs
    └─── required
        └── required.cljs

I'd like file1.cljs (namespaced as file1.file1 ) and file2.cljs (namespaced as file2.file2 ) to require required.cljs (namespaced as required.required ).

My :cljsbuild looks like:

:cljsbuild {:builds
            [{:source-paths ["src-cljs/project/file1"]
              :compiler {:output-to "resources/public/js/file1.js"}}
             {:source-paths ["src-cljs/project/file2"]
              :compiler {:output-to "resources/public/js/file2.js"}}]}

When I (:require [required.required :as required]) and compile I get the exception:

Caused by: clojure.lang.ExceptionInfo: No such namespace: required.required, could not locate required/required.cljs, required/required.cljc, or Closure namespace "required.required" at line 1 src-cljs/project/file1/file1.cljs

You don't usually want a separate js output file and cljsbuild profile for each namespace. You want one single cljsbuild profile including all of your namespaces. Something like:

:cljsbuild {:builds
            [{:source-paths ["src-cljs/project"]
              :compiler {:output-to "resources/public/js/project.js"}}]}

Not only that: you might want to have ["src-cljs"] as :source-paths and then name your namespaces like project.ns1.sub-ns1 . But you can do it without the project ns prefix just fine.

You can find an example of this simple layout in the simple example project from lein-cljsbuild

Looking to the cljsbuild README, it seems like you were taking the path of "Multiple build configurations" . In practice this is mostly used to have separate build profiles for your main code and the tests working against that code. That's shown in the advanced example .
