Lumo

Fast, cross-platform, standalone ClojureScript environment. Lumo is a standalone ClojureScript environment that runs on Node.js and the V8 JavaScript engine. It starts up instantaneously and provides out-of-the-box access to the entire Node.js ecosystem, including a ClojureScript REPL. 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. 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. Enter lumo at the command line to launch the ClojureScript REPL.
