Rails - How do I check if js file exists before requiring it in application.js?

I forked the plutus gem (https://github.com/mbulat/plutus) and it has a requirement of jquery.ui.datepicker. rails-jquery-ui gem 5.0 changed folder name to jquery-ui (previous jquery.ui). Hence, this returns a Sprockets::FileNotFound for my app which depends on rails-jquery-ui 5.0.

How do I conditionally include jquery.ui.datepicker or jquery-ui/datepicker in plutus application.js so that the gem is usable by people who may have any gem version.

Is my approach correct or is there a better way to do this?

You could rename the application.js to application.js.erb and include any ruby conditional in there.

Once you rename it to application.js.erb you could write something like the following:

<% if Jquery::Ui::Rails::VERSION >= '5.0' %>
  //= require jquery-ui/datepicker
<% else %>
  //= require jquery.ui.datepicker
<% end %>

I have not checked the actual file names or folder structure. Above code is just a pseudo code, adapt it to your need/requirement.
