Duct ClojureScript Module

A Duct module that adds support for compiling ClojureScript for use in web applications.

Installation

Add the following dependency to your deps.edn file:

org.duct-framework/module.cljs {:mvn/version "0.6.0"}

Or to your Leiningen project file:

[org.duct-framework/module.cljs "0.6.0"]

Usage

Add the :duct.module/cljskey to your configuration and set the main namespace and the JavaScript output file:

{:duct.module/cljs {:main example.client, :output-file "client.js"}}

This configuration will generate a file target/cljs/client.js from the example.client namespace. The target/cljs directory will be added to the web application's static file handler, :duct.handler/file. This will make the generated JavaScript accessible at /cljs/client.js.

The module can be configured further with the options:

• :output-dir - the directory to put the compiled JavaScript in (defaults to "target/cljs")
• :asset-path - the web server path where the compiled JavaScript can be accessed (defaults to "/cljs")

When run in under the REPL profile, a server will be started that will update the compiled JavaScript each time the environment is (reset).

When run in under the main profile, the ClojureScript will be compiled for production. This will be slower, but produce a smaller output.
