Lumo is a standalone ClojureScript environment that runs on Node.js and the V8 JavaScript engine. It starts up instantaneously and has out-of-the-box access to the entire Node.js ecosystem.
Lumo also provides a ClojureScript build API, making it possible to compile ClojureScript projects entirely without the JVM, thanks to the experimental JavaScript version of the Google Closure Compiler.

npm is a package runner that comes with node6+. You can try lumo "without install" with:
npx -p lumo-cljs lumo
$ npm install -g lumo-cljs
If you get a permission failure, try this:
$ npm install -g lumo-cljs --unsafe-perm
Note: the installed binary will be named lumo rather than lumo-cljs
$ brew install lumo
Note: If you want to install a binary built from master, run brew install --HEAD lumo
(at your own responsibility).
$ docker pull anmonteiro/lumo:latest
$ docker run -it anmonteiro/lumo
$PATH.Enter lumo at the command line to launch it.
Check out lumo -h for usage instructions and supported command line options.
Lumo can compile ClojureScript code as of version 1.2.0. See the introductory
blog post.
It is still considered experimental, given the relatively new Google Closure
Compiler port to JavaScript,
but it aims to be at feature parity with the JVM ClojureScript compiler.
The build API mirrors the ClojureScript one. Please reference its
Quick Start and the
Compiler Options. You
can basically just replace the namespace with lumo.build.api:
(require 'lumo.build.api)
(lumo.build.api/build "src" {:output-to "out/main.js"})
The following example also shows how to use multiple source folders.
(require '[lumo.build.api :as b])
(b/build
(b/inputs "src1" "src2") ;; variadic
{:output-to "out/main.js"})
To build Lumo from source:
boot release.build/lumo (or build\lumo.exe if you're
on Windows).See CONTRIBUTING.md.
