ColdBox Elixir has a few helper methods when working in a ContentBox app.

const elixir = require("coldbox-elixir");
​
module.exports = elixir(mix => {
    mix.themes();
    mix.contentbox();
});

These two methods work just like a call to mix.modules with some different defaults set.

For a refresher on how mix.modules and elixir-module.js files work, see the modules docs.​

mix.themes

This method will look inside the modules_app/contentbox-custom/_themes directory for any folders with a elixir-theme.js file. The elixir-theme.js file is identical to a elixir-module.js file.

mix.contentbox

This method will look inside the modules_app/contentbox-custom/_modules directory for any folders with a elixir-module.js file.
