CKEditor 5 SVGs do not build properly

• Laravel Mix Version: 1.7.2
• Node Version: v8.9.4
• NPM Version: 5.6.0
• Yarn Version: 1.3.2
• OS: Fedora release 27

Description:

I am attempting to use the new CKEditor 5 Framework with Mix. As described in the CKEditor Quick Start Guide I have imported CKEditor libs into app.js (and removed everything else) then I built the file. The results seem to show the SVGs are not loaded properly and the icons in the editor toolbar are missing.

https://screenshots.firefox.com/LEYu0SnGQVMaew0E/127.0.0.1

I also receive this error output in the console.

XML Parsing Error: not well-formed
Location: http://127.0.0.1:8000/
Line Number 1, Column 1:
127.0.0.1:8000:1:1

I then attempted to fix the svg loader issue with the webpack config recommended on the guide.

mix.js('resources/assets/js/app.js', 'public/js').webpackConfig({
  module: {
    rules: [{
      test: /ckeditor5-[^/]+\/theme\/icons\/[^/]+\.svg$/,

      use: ['raw-loader']

    }]
  }
});

It produces the same result. I also tried the full webpack config:

mix.js('resources/assets/js/app.js', 'public/js').webpackConfig({
  module: {
    rules: [{
      test: /ckeditor5-[^/]+\/theme\/icons\/[^/]+\.svg$/,

      use: ['raw-loader']

    }, {
      test: /ckeditor5-[^/]+\/theme\/[^/]+\.scss$/,

      use: [
        'style-loader',
        'css-loader',
        'sass-loader'
      ]
    }]
  }
});

But I get errors:

ERROR  Failed to compile with 1 errors                                                                                                                                                                    17:29:16

 @ multi ./resources/assets/js/app.js

Here is the app.js

// app.js
import ClassicEditor from '@ckeditor/ckeditor5-editor-classic/src/classiceditor';
import Essentials from '@ckeditor/ckeditor5-essentials/src/essentials';
import Paragraph from '@ckeditor/ckeditor5-paragraph/src/paragraph';
import Bold from '@ckeditor/ckeditor5-basic-styles/src/bold';
import Italic from '@ckeditor/ckeditor5-basic-styles/src/italic';

ClassicEditor
    .create( document.querySelector( '#editor' ), {
        plugins: [ Essentials, Paragraph, Bold, Italic ],
        toolbar: [ 'bold', 'italic' ]
    } )
    .then( editor => {
        console.log( 'Editor was initialized', editor );
    } )
    .catch( error => {
        console.error( error.stack );
    } );

Without the custom webpack configurations mix says the SVGs are exported. I’m not sure where they are being exported.

Done in 4.47s.

Steps To Reproduce:

1. Create a new Laravel Project
2. Add CKEditor via yarn/npm

yarn && yarn add \@ckeditor/ckeditor5-editor-classic \
    @ckeditor/ckeditor5-essentials \
    @ckeditor/ckeditor5-paragraph \
    @ckeditor/ckeditor5-basic-styles

1. Add the previous app.js and build the js with yarn dev
2. Set the welcome.blade.php file to the following:

<!doctype html>
<html lang="{{ app()->getLocale() }}">

<head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1">

  <title>Laravel</title>

  <!-- Fonts -->
  <link href="https://fonts.googleapis.com/css?family=Raleway:100,600" rel="stylesheet" type="text/css">
</head>

<body>
  <div id="editor">
    <p>Editor content goes here.</p>
  </div>

  <script src="js/app.js"></script>
</body>

</html>

1. Load the project homepage.

Here’s how i ended up overriding the default laravel-mix to correctly compile CKEditor5 without modifying it

• Removed all --config=node_modules/laravel-mix/setup/webpack.config.js in package.json scripts
• Then imported laravel-mix default config and override in webpack.config.js

const defaultConfig = require('laravel-mix/setup/webpack.config.js')
const { styles } = require('@ckeditor/ckeditor5-dev-utils')

const ckeditor5_pattern = {
  svg: /ckeditor5-[^/]+\/theme\/icons\/[^/]+\.svg$/,
  css: /ckeditor5-[^/]+\/theme\/[\w-/]+\.css$/,
}

defaultConfig.module.rules.map(rule => {
  for (let key in ckeditor5_pattern) {
    if (`test.${key}`.match(rule.test)) {
      if (rule.exclude) {
        if (rule.exclude instanceof Array)
          rule.exclude.push(ckeditor5_pattern[key])
        else
          rule.exclude = [rule.exclude, ckeditor5_pattern[key]]
      } else
        rule.exclude = ckeditor5_pattern[key]
    }
  }

  return rule
})

const rules = [
  {
    test: ckeditor5_pattern['svg'],
    use: [ 'raw-loader' ]
  },
  {
    test: ckeditor5_pattern['css'],
    use: [
      {
        loader: 'style-loader',
        options: {
          singleton: true
        }
      },
      {
        loader: 'postcss-loader',
        options: styles.getPostCssConfig( {
          themeImporter: {
            themePath: require.resolve('@ckeditor/ckeditor5-theme-lark')
          },
          minify: true
        } )
      },
    ]
  }
]

defaultConfig.module.rules = defaultConfig.module.rules.concat(rules)

module.exports = defaultConfig
