Can ActiveAdmin load javascript bundled by webpack? - Rails 5.1

Question

I've upgraded from rails 4.2.6 to rails 5.1, and then started to use webpack.
All set up for using webpack have done, but I can't figure out how to load javascript files on the ActiveAdmin page.
ActiveAdmin loads app/assets/javascripts/active_admin.js.coffee by default.
Is there a way to load javascript files which is bundled by webpack on the ActiveAdmin page?

Answer 1

Webpack is not yet officially supported. The approach we are using for now is to monkey patch ActiveAdmin::Views::Header to include tags to load the generated output of Webpack, eg.

class ActiveAdmin::Views::Header < Component
  def build(namespace, menu)
    ...
    render "application/custom_header_tags"
  end
end

In our case our custom_header_tags.erb uses React On Rails but substitute whatever integration you prefer.
