CKEDITOR has incorrect basepath when using NPM & Laravel Mix

When I attempt to include CKEDITOR into my new Laravel 5.5 project using NPM, I get the following error in Chrome Console (using laravel Valet for the local.dev):

app.js:16991 GET http://ift.tt/2wyIxEZ 
app.js:16991 GET http://ift.tt/2vCW80I 
app.js:16991 GET http://ift.tt/2wyPSE8 

My Laravel Mix setup looks like this:

mix.js('resources/assets/js/app.js', 'public/js')
  .babel(['resources/assets/js/libraries/*.js'], 'public/js/vendor.js')
  .version();

My CKEDITOR installation is located in:

/vendor/ckeditor/ckeditor

I am able to access the CKEDITOR instance when the site has loaded. However, as displayed above, when I navigate to https://local.dev/chart, CKEDITOR now looks for the config, skin, and lang files with /chart appended to it's basepath.

I did some research, and found some related issues and was able to change the base_path using asset() successfully. The related stackOverflow questions can be found here and here.

What I would like to do is pull CKEDITOR in through NPM, use Laravel Mix to combine, version, and minify my scripts (one for vendor libraries, one for my app-specific JS), and then output those two.js files to these directories in the laravel app:

 /public/js/vendor.js
 /public/js/app.js

Laravel mix produces these two files, builds successfully, and all other libraries play nicely. However, CKEDITOR loses it's base path and throws errors looking for skins / langs / config.js -- any idea how I can adjust CKEDITOR's basePath to point to the vendor files so that it'll stop squaking these errors and work correctly?

Thanks you in advance for any assistance you can provide!
