node-cljs

Run compiled ClojureScript code with node.js. Skip :target :nodejs and (set! *main-cli-fn* ...) and call any exported function from the command line.

Install

npm install -g node-cljs

Usage

usage: node-cljs :output-to [-m namespace.main_fn [arg...]]
       node-cljs :output-dir :output-to [-a] [-r namespace]... [-m namespace.main_fn [arg...]]

Namespaces and functions need to use the munged form, that is, cemerick.cljs.test.run_all_tests, not cemerick.cljs.test.run-all-tests.

Unless one of the namespaces you'll load has a side effect (why would you do this?!), specify the function to call with -m.

Unoptimized

When compiled with :optimizations :none, the first argument points to :output-dir (the directory containing goog/base.js) and the second is :output-to.

The -r option will load a namspace, and the -a option will load all namespaces. This is useful when the main function you are calling depends on other namespaces without requiring them, like cemerick.cljs.test.run-all-tests. If you compile with optimization, all your tests will be included in the :output-to file, but without optimization they will need to be explicitly required.

Optimized

For all other :optimization levels, you only need to specify the single file :output-to.

Examples

Given this lein-cljsbuild configuration:

# require all namespaces and run all tests for an unoptimized build
node-cljs target/cljs/unoptimized target/cljs/unoptimized.js -a -m cemerick.cljs.node.run_all_tests

# run cemerick.cljs.test.basic with a build optimized with :advanced
node-cljs target/cljs/advanced.js -m cemerick.cljs.node.run_tests cemerick.cljs.test.basic

# require cemerick.cljs.test.fixtures and run all tests for an unoptimized build
node-cljs target/cljs/unoptimized target/cljs/unoptimized.js -r cemerick.cljs.test.fixtures -m cemerick.cljs.node.run_all_tests
