未定义窗口- react-draft-wysiwyg用于下一个js (ssr)

Question

我正在开发一个富文本编辑器，用于将纯html转换为ssr下一个js的编辑器内容。我得到此错误窗口未定义，因此我搜索此github link的解决方案

它使用了next js的动态导入功能。

而不是直接导入编辑器import { Editor } from "react-draft-wysiwyg";

它使用此代码动态导入编辑器

const Editor = dynamic(
  () => {
    return import("react-draft-wysiwyg").then(mod => mod.Editor);
  },
  { ssr: false }
);

尽管我已经安装了react-draft-wysiwyg模块，但我仍然收到这个错误

ModuleParseError: Module parse failed: Unexpected token (19:9)
You may need an appropriate loader to handle this file type.
| import dynamic from "next/dynamic";
| var Editor = dynamic(function () {
>   return import("react-draft-wysiwyg").then(function (mod) {
|     return mod.Editor;
|   });

这是我的全部代码

import React, { Component } from "react";
import { EditorState } from "draft-js";
// import { Editor } from "react-draft-wysiwyg";
import dynamic from "next/dynamic";

const Editor = dynamic(
  () => {
    return import("react-draft-wysiwyg").then(mod => mod.Editor);
  },
  { ssr: false }
);

class MyEditor extends Component {
  constructor(props) {
    super(props);
    this.state = { editorState: EditorState.createEmpty() };
  }

  onEditorStateChange = editorState => {
    this.setState({ editorState });
  };

  render() {
    const { editorState } = this.state;

    return (
      <div>
        <Editor
          editorState={editorState}
          wrapperClassName="rich-editor demo-wrapper"
          editorClassName="demo-editor"
          onEditorStateChange={this.onEditorStateChange}
          placeholder="The message goes here..."
        />
      </div>
    );
  }
}

export default MyEditor;

请帮帮我。谢谢。

以下是一种解决方法

import dynamic from 'next/dynamic'
import { EditorProps } from 'react-draft-wysiwyg'

// install @types/draft-js @types/react-draft-wysiwyg and @types/draft-js @types/react-draft-wysiwyg for types

const Editor = dynamic<EditorProps>(
  () => import('react-draft-wysiwyg').then((mod) => mod.Editor),
  { ssr: false }
)

使用Next.js和Strapi后端的Draft.js所见即所得，使用图像上传创建和查看文章

import React, { Component } from 'react'
import { EditorState, convertToRaw } from 'draft-js';
import draftToHtml from 'draftjs-to-html'; 
import dynamic from 'next/dynamic';
const Editor = dynamic(
() => import('react-draft-wysiwyg').then(mod => mod.Editor),
{ ssr: false })  

import "react-draft-wysiwyg/dist/react-draft-wysiwyg.css";


export default class ArticleEditor extends Component {

constructor(props) {
    super(props);

    this.state = {
        editorState: EditorState.createEmpty()
    };
}

onEditorStateChange = (editorState) => {
    this.setState({
        editorState,
    });
    this.props.handleContent(
        convertToRaw(editorState.getCurrentContent()
    ));
};

  uploadImageCallBack = async (file) => {
    const imgData = await apiClient.uploadInlineImageForArticle(file);
    return Promise.resolve({ data: { 
      link: `${process.env.NEXT_PUBLIC_API_URL}${imgData[0].formats.small.url}`
    }});
  }

render() {
    const { editorState } = this.state;
    return (
        <>
            <Editor
                editorState={editorState}
                toolbarClassName="toolbar-class"
                wrapperClassName="wrapper-class"
                editorClassName="editor-class"
                onEditorStateChange={this.onEditorStateChange}
                toolbar={{
                    options: ['inline', 'blockType', 'fontSize', 'fontFamily', 'list', 'textAlign', 'colorPicker', 'link', 'embedded', 'emoji', 'image', 'history'],
                    inline: { inDropdown: true },
                    list: { inDropdown: true },
                    textAlign: { inDropdown: true },
                    link: { inDropdown: true },
                    history: { inDropdown: true },
                    image: {
                        urlEnabled: true,
                        uploadEnabled: true,
                        uploadCallback: this.uploadImageCallBack,
                        previewImage: true,
                        alt: { present: false, mandatory: false }
                    },
                }}
            />
            <textarea
                disabled
                value={draftToHtml(convertToRaw(editorState.getCurrentContent()))}
            />
        </>
    )
}

}

尝试在React使用useEffect钩子更新DOM之后返回Editor。例如：

const [editor, setEditor] = useState<boolean>(false)
  useEffect(() => {
    setEditor(true)
  })

  return (
    <>
      {editor ? (
        <Editor
          editorState={editorState}
          wrapperClassName="rich-editor demo-wrapper"
          editorClassName="demo-editor"
          onEditorStateChange={this.onEditorStateChange}
          placeholder="The message goes here..."
        />
      ) : null}
    </>
  )
