:foreign-libs with module conversion does not works properly if it is used form deps.cljs


  • Type: Defect Defect
  • Status: Closed Closed
  • Priority: Minor Minor
  • Resolution: Completed
  • Affects Version/s: 1.9.36, 1.9.76
  • Fix Version/s: None
  • Component/s: None
  • Environment:
    Linux, openjdk8
  • Patch:


When :foreign-libs is used for consume commonjs (or amd) modules from clojurescript using the `deps.cljs` mechanism, an unexpected "internal compiler error" is raised. When the same configuration is attached on the build script, everything works as expected.

Simple way to reproduce that, create sample directory tree:

mkdir tmp;
cd tmp;
mkdir -p src/testapp
mkdir -p src/vendor
touch src/testapp/core.cljs
touch src/vendor/greeter.js

Download the latest compiler or copy the recently build one from master:


Create the sample cljs file:

;; tmp/src/testapp/core.cljs
(ns testapp.core
  (:require [cljs.nodejs :as nodejs]
            [greeter.core :as g]))


(defn -main
  [& args]
  (println (g/sayHello "Ciri")))

(set! *main-cli-fn* -main)

Create the sample commonjs module:

"use strict";

exports.sayHello = function(name) {
  return `Hello ${name}!`;

Create the build script (that works):

;; tmp/build.clj
(require '[ :as b])

(b/build "src"
 {:main 'testapp.core
  :output-to "out/main.js"
  :output-dir "out"
  :target :nodejs
  :language-in  :ecmascript6
  :language-out :ecmascript5
  :foreign-libs [{:file "vendor/greeter.js"
                  :module-type :commonjs
                  :provides ["greeter.core"]}]
  :verbose true})

And compile this using the following command:

java -cp cljs.jar:src clojure.main build.clj

This will generate successfully the final artifact that can be successufully executed with node:

node out/main.js
# => "Hello Ciri!"

But, if you remove the `:foreign-libs` from the build script and create a new `src/deps.cljs` file
with the following content:

{:foreign-libs [{:file "vendor/greeter.js"
                 :module-type :commonjs
                 :provides ["greeter.core"]}]}

And try compile it:
