cocoon-js

Contains the Javascript dependency for the cocoon rubygem. The existing gem has a dependency on JQuery that requires you loading JQuery manually via the asset pipeline. JQuery is no longer added by default in Rails 5, and manually adding it back breaks some rails-ujs functionality. This package contains the cocoon.js code, and installs jQuery via npm

• Install the cocoon rubygem as usual
• In a JS file that relies on the cocoon javascript, import cocoon-js at the top of the file

For example, if you're using webpacker and have an application.js entrypoint, you can do:

// app/javascript/packs/application.js
import "cocoon-js";
