我一直在阅读这篇文章：https ://www.codementor.io/@vuejsdevelopers/critical-css-and-webpack-automatically-minimize-render-blocking-css-aaifvn8vw

我希望自动构建一个内联到我的 application.html.erb 视图文件中的关键 CSS 文件。

问题是我不确定如何将 Webpack 插件集成到我的应用程序中。我不确定要修改哪个文件以及如何修改该文章与 Webpacker 无关。

我拥有的文件是：

webpacker.yml：

# Note: You must restart bin/webpack-dev-server for changes to take effect

default: &default
  source_path: app/javascript
  source_entry_path: packs
  public_root_path: public
  public_output_path: packs
  cache_path: tmp/cache/webpacker
  check_yarn_integrity: false
  webpack_compile_output: true

  # Additional paths webpack should lookup modules
  # ['app/assets', 'engine/foo/app/assets']
  resolved_paths: ['../node_modules']

  # Reload manifest.json on all requests so we reload latest compiled packs
  cache_manifest: false

  # Extract and emit a css file
  extract_css: false

  static_assets_extensions:
    - .jpg
    - .jpeg
    - .png
    - .gif
    - .tiff
    - .ico
    - .svg
    - .eot
    - .otf
    - .ttf
    - .woff
    - .woff2
    - .webp

  extensions:
    - .mjs
    - .js
    - .sass
    - .scss
    - .css
    - .module.sass
    - .module.scss
    - .module.css
    - .png
    - .svg
    - .gif
    - .jpeg
    - .jpg

development:
  <<: *default
  compile: true

  # Verifies that correct packages and versions are installed by inspecting package.json, yarn.lock, and node_modules
  check_yarn_integrity: true

  # Reference: https://webpack.js.org/configuration/dev-server/
  dev_server:
    https: false
    host: localhost
    port: 3035
    public: localhost:3035
    hmr: false
    # Inline should be set to true if using HMR
    inline: true
    overlay: true
    compress: true
    disable_host_check: true
    use_local_ip: false
    quiet: false
    pretty: false
    headers:
      'Access-Control-Allow-Origin': '*'
    watch_options:
      ignored: '**/node_modules/**'


test:
  <<: *default
  compile: true

  # Compile test packs to a separate directory
  public_output_path: packs-test

production:
  <<: *default

  # Production depends on precompilation of packs prior to booting for performance.
  compile: false

  # Extract and emit a css file
  extract_css: true

  # Cache manifest.json for performance
  cache_manifest: true

webpack/development.js：

process.env.NODE_ENV = process.env.NODE_ENV || 'development'

const environment = require('./environment')

module.exports = environment.toWebpackConfig()

webpack/environment.js：

const { environment } = require('@rails/webpacker')

environment.config.merge({
  devtool: 'cheap-source-map',
  performance: {
    hints: false
  }
})

module.exports = environment

const webpack = require('webpack')
environment.plugins.prepend('Provide',
  new webpack.ProvidePlugin({
    $: 'jquery/src/jquery',
    jQuery: 'jquery/src/jquery'
  })
)

webpack/production.js：

process.env.NODE_ENV = process.env.NODE_ENV || 'production'

const environment = require('./environment')

module.exports = environment.toWebpackConfig()

谁能指出我正确的方向以及如何实现这一目标？

提前致谢！
