optimus-jsx Build Status

A React JSX asset loader for Optimus.


  • Add [optimus-jsx "0.1.1"] to :dependencies in your project.clj.
  • It requires Optimus version minimum 0.13.6.


Add (:require optimus-jsx.core) to the namespace declaration where you're loading assets.

The load-jsx-asset function will be declared as a custom loader for .jsx files with Optimus' load-asset multimethod. This is in turn used by load-assets, load-bundle and load-bundles - so everything works like before, but now it also supports JSX files.


The .jsx files are immediately transpiled into .js files. This means you can safely bundle JS and JSX files together. It also means that the bundle identifier has to be .js. Like so:

(assets/load-bundle "public"


Yes, please do.

If you're looking to add other transpilers, I think that would be best in a separate project. But please do let me know about it, so I can link to it in the Optimus README. :-)

Remember to add tests for your feature or fix, or I'll certainly break it later.

Installing dependencies

You need npm installed to fetch the JavaScript dependencies. The actual fetching is automated however.

Running the tests

lein midje will run all tests.

lein midje :autotest will run all the tests indefinitely. It sets up a watcher on the code files. If they change, only the relevant tests will be run again.
