What would you like to do?
rails + webpacker + webpack-dev-server + vue + remote dev vps and nginx

Process goes something like this:

bundle update webpacker
rails webpacker:binstubs
yarn upgrade @rails/webpacker@4.0.0-pre.2 # or 'add' instead of upgrade
yarn upgrade webpack-dev-server@"'3.1.4'  # or 'add' instead of upgrade
yarn add webpack-cli

bundle exec rails webpacker:install # don't do this! the scrpit seems to overwrite the @rails/webpacker version to 3.5.3

Contents of files in result:

# gemfile
gem 'webpacker', github: 'rails/webpacker', branch: 'master'
# or gem 'webpacker', '>= 4.0.x' # since we don't always know what 'master' will be on
# gemfile.lock
  revision: 191099e682b7c0d8a64effd14f31e9ee7423eb27
  branch: master
    webpacker (4.0.0.pre.pre.2)
# config/initializers/content_security_policy.rb
# maybe both of these needed?
policy.connect_src :self, :https, "http://localhost:3035", "ws://localhost:3035" # for webpack-dev-server
policy.connect_src :self, :https, "http://REMOTE_URL_HERE", "ws://REMOTE_URL_HERE" # for webpack-dev-server
// config/webpack/loaders/vue.js
const { environment } = require('@rails/webpacker')
const webpack = require('webpack')
const { VueLoaderPlugin } = require('vue-loader')

  new VueLoaderPlugin()
