How to use prettier/standalone in the browser with Rails app and Webpacker

I need to format css in a wysiwyg editor in the browser. I want to use Prettier for this. The app is Rails 5.2 that uses Webpacker and Vue.

I am following the documentation here:

I run yarn add prettier

Then, in my .js file I have:

import prettier from 'prettier';
import parserCss from 'prettier/parser-postcss';

prettier.format(".foo{color: red;}", {
  parser: "css",
  plugins: [parserCss],

This works in my local development environment, but when I try to deploy the application, the build fails during Webpack compile.

I think I need to configure my webpack or something. If you need more information just let me know and I will update the question.
