无法加载通过 ember-auto-import 导入 css 的模块

Question

我正在尝试构建一个 ember 3.25 应用程序，它通过 ember-auto-import

导入 CkEditor

通过将以下内容添加到我的 package.json，我能够让编辑器正常工作：

"@ckeditor/ckeditor5-build-classic": "^27.0.0",

并将以下内容添加到我的 ember 组件中：

import ClassicEditor from '@ckeditor/ckeditor5-build-classic';

...

didInsertElement() {
  var editor = ClassicEditor
    .create( document.querySelector( '#editor' ), {
      ...
    });
}

但是当我尝试通过以下方式添加 ImageResize 模块时：

"@ckeditor/ckeditor5-image": "^27.0.0",

在我的组件中 (as instructed here):

import Image from '@ckeditor/ckeditor5-image/src/image';
import ImageResize from '@ckeditor/ckeditor5-image/src/image-resize';

我最初看到的错误是：'UnhandledPromiseRejectionWarning: Error: webpack returned errors to ember-auto-import 所以我运行 AUTO_IMPORT_VERBOSE=true ember serve

我现在看到 ckeditor 无法 @import 嵌套的错误 .css:

ERROR in ./node_modules/@ckeditor/ckeditor5-ui/theme/components/toolbar/toolbar.css 6:0
Module parse failed: Unexpected character '@' (6:0)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
|  */

> @import "../../mixins/_unselectable.css";

或者使用 ES6 语法：

Module parse failed: Unexpected token (6:0)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

> :root {

以及尝试包含 svg 文件时的错误：

ERROR in ./node_modules/@ckeditor/ckeditor5-widget/theme/icons/drag-handle.svg 1:0
Module parse failed: Unexpected token (1:0)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

基于此消息：

You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

看来我需要向 ember 添加一些 webpack 加载程序，但我真的不确定该怎么做。有人可以帮忙吗？

@ckeditor/ckeditor5-image/src/image imports a CSS file. As CKEditor uses CSS-in-JS and other features not part of ECMAScript specification you need to configure webpack to support it. CKEditor's documentation includes a minimal configuration example:

const CKEditorWebpackPlugin = require("@ckeditor/ckeditor5-dev-webpack-plugin");
const { styles } = require("@ckeditor/ckeditor5-dev-utils");

module.exports = {
  plugins: [
    // ...

    new CKEditorWebpackPlugin({
      // See https://ckeditor.com/docs/ckeditor5/latest/features/ui-language.html
      language: "pl",
    }),
  ],

  module: {
    rules: [
      {
        test: /ckeditor5-[^/\]+[/\]theme[/\]icons[/\][^/\]+\.svg$/,
        use: ["raw-loader"],
      },
      {
        test: /ckeditor5-[^/\]+[/\]theme[/\].+\.css$/,
        use: [
          {
            loader: "style-loader",
            options: {
              injectType: "singletonStyleTag",
              attributes: {
                "data-cke": true,
              },
            },
          },
          {
            loader: "postcss-loader",
            options: styles.getPostCssConfig({
              themeImporter: {
                themePath: require.resolve("@ckeditor/ckeditor5-theme-lark"),
              },
              minify: true,
            }),
          },
        ],
      },
    ],
  },
};

Ember 自动导入允许您提供自定义 webpack 配置作为 autoImport.webpack 配置键：

// ember-cli-build.js

let app = new EmberApp(defaults, {
  autoImport: {
    webpack: {
      // extra webpack configuration goes here
    },
  },
});

请联系 Ember Auto Import's documentation 了解详情。

像这样将两者放在一起应该有效：

// ember-cli-build.js

const CKEditorWebpackPlugin = require('@ckeditor/ckeditor5-dev-webpack-plugin');
const { styles } = require('@ckeditor/ckeditor5-dev-utils');

let app = new EmberApp(defaults, {
  autoImport: {
    webpack: {
      plugins: [
        new CKEditorWebpackPlugin({
          // See https://ckeditor.com/docs/ckeditor5/latest/features/ui-language.html
          language: "pl",
        }),
      ],
      module: {
        rules: [
          {
            test: /ckeditor5-[^/\]+[/\]theme[/\]icons[/\][^/\]+\.svg$/,
            use: ["raw-loader"],
          },
          {
            test: /ckeditor5-[^/\]+[/\]theme[/\].+\.css$/,
            use: [
              {
                loader: "style-loader",
                options: {
                  injectType: "singletonStyleTag",
                  attributes: {
                    "data-cke": true,
                  },
                },
              },
              {
                loader: "postcss-loader",
                options: styles.getPostCssConfig({
                  themeImporter: {
                    themePath: require.resolve(
                      "@ckeditor/ckeditor5-theme-lark"
                    ),
                  },
                  minify: true,
                }),
              },
            ],
          },
        ],
      },
    },
  },
});

更新

这个解决方案几乎有效，但有几点需要注意：

正在从“@ckeditor/ckeditor5-image/src/image-resize”导入 ImageResize； '@ckeditor/ckeditor5-build-classic' 中的 ClassicEditor 并没有起作用！显然这会导致重复模块错误。

因此，请按照有关如何 build from source after doing that, I found that the ckeditor styling was not loading in ember until I followed the instructions on extracting CSS 的说明进行操作，然后一切正常！

以下是我的 package.json:

还有我的 ember-cli-build.js 文件：

  const CKEditorWebpackPlugin = require("@ckeditor/ckeditor5-dev-webpack-plugin");
  const { styles } = require("@ckeditor/ckeditor5-dev-utils");
  const MiniCssExtractPlugin = require( 'mini-css-extract-plugin' );


  module.exports = function (defaults) {
    let app = new EmberApp(defaults, {

     cssModules: {
       includeExtensionInModulePath: true,
     },

      sassOptions: {

            new MiniCssExtractPlugin( {
              filename: 'ckeditor.css'
            } )
          ],
          module: {

                  'css-loader',
                  {
                    loader: "postcss-loader",
                    options: styles.getPostCssConfig({

                      ),
                    },
                    minify: true,
                  }),
                },
              ],
            },
          ],
        },
      },
    },
  });


  return app.toTree();
};

还有我的 ck-editor.js 文件（我将其保存在与我的组件相同的目录中）：

import ClassicEditorBase from '@ckeditor/ckeditor5-editor-classic/src/classiceditor';
import EssentialsPlugin from '@ckeditor/ckeditor5-essentials/src/essentials';
import UploadAdapterPlugin from '@ckeditor/ckeditor5-adapter-ckfinder/src/uploadadapter';
import AutoformatPlugin from '@ckeditor/ckeditor5-autoformat/src/autoformat';
import BoldPlugin from '@ckeditor/ckeditor5-basic-styles/src/bold';
import ItalicPlugin from '@ckeditor/ckeditor5-basic-styles/src/italic';
import BlockQuotePlugin from '@ckeditor/ckeditor5-block-quote/src/blockquote';
// import EasyImagePlugin from '@ckeditor/ckeditor5-easy-image/src/easyimage';
import HeadingPlugin from '@ckeditor/ckeditor5-heading/src/heading';
import ImagePlugin from '@ckeditor/ckeditor5-image/src/image';
import ImageCaptionPlugin from '@ckeditor/ckeditor5-image/src/imagecaption';
import ImageStylePlugin from '@ckeditor/ckeditor5-image/src/imagestyle';
import ImageToolbarPlugin from '@ckeditor/ckeditor5-image/src/imagetoolbar';
import ImageUploadPlugin from '@ckeditor/ckeditor5-image/src/imageupload';
import LinkPlugin from '@ckeditor/ckeditor5-link/src/link';
import ListPlugin from '@ckeditor/ckeditor5-list/src/list';
import ParagraphPlugin from '@ckeditor/ckeditor5-paragraph/src/paragraph';
import ImageResize from '@ckeditor/ckeditor5-image/src/imageresize';

export default class ClassicEditor extends ClassicEditorBase {}

ClassicEditor.builtinPlugins = [
    EssentialsPlugin,
    UploadAdapterPlugin,
    AutoformatPlugin,
    BoldPlugin,
    ItalicPlugin,
    BlockQuotePlugin,
    // EasyImagePlugin,
    HeadingPlugin,
    ImagePlugin,
    ImageCaptionPlugin,
    ImageStylePlugin,
    ImageToolbarPlugin,
    ImageUploadPlugin,
        ImageResize,
    LinkPlugin,
    ListPlugin,
    ParagraphPlugin
];

ClassicEditor.defaultConfig = {
    toolbar: {
        items: [
            'heading',
            '|',
            'bold',
            'italic',
            'link',
            'bulletedList',
            'numberedList',
            'uploadImage',
            'blockQuote',
            'undo',
            'redo'
        ]
    },
    image: {
        toolbar: [
            'imageStyle:full',
            'imageStyle:side',
            '|',
            'imageTextAlternative'
        ]
    },
    language: 'en'
};

现在，从我的组件中，我可以调用：

import ClassicEditor from './ck-editor';

...

didInsertElement() {
  var editor = ClassicEditor
    .create( document.querySelector( '#editor' ), {
      ...
    });
}

无法加载通过 ember-auto-import 导入 css 的模块

Can't load module that imports css via ember-auto-import

javascript

webpack

ember.js

ckeditor
