NextJS项目中需要使用CkEditor5作为富文本编辑器，按照官网React CkEditor5手册使用出现如下错误：

node_modules/@ckeditor/ckeditor5-react/dist/index.js (5:242) @ eval
 ⨯ ReferenceError: self is not defined

还是因为nextjs的服务器端渲染造成的错误，富文本编辑器一般用在表单提交页面，没有使用ssr的必要，想要解决上面问题，动态导入组件，禁用ssr就可以解决。

1、封装ckeditor组件

"use client"

import { CKEditor } from '@ckeditor/ckeditor5-react';
import ClassicEditor from '@ckeditor/ckeditor5-build-classic';

export function CustomCkEditor(props: {data: string, onChange: (content: string)=>void}) {
  
  const editorConfiguration = {
    toolbar: [
      'heading', //类型
      '|',
      'bold', //加粗
      'italic', //斜体
      'link', //超链接
      'bulletedList',// 无序列表
      'numberedList', //有序列表
      '|',
      'indent', //左缩进
      'outdent', //右缩进
      '|',
      'imageUpload', //图片上传
      'blockQuote', //引用
      'insertTable', //插入图标
      //'mediaEmbed', //视频上传
      'undo', //撤销
      'redo'//重做
    ]
  };

  return (
    <CKEditor
        config={ editorConfiguration }
        editor={ ClassicEditor }
        data={ props.data }
        onReady={ editor => {
            // You can store the "editor" and use when it is needed.
            console.log( 'Editor is ready to use!', editor );
        } }
        onChange={ ( event, editor ) => {
            const data = editor.getData();
            props.onChange(data)
            console.log( { event, editor, data } );
        } }
        onBlur={ ( event, editor ) => {
            console.log( 'Blur.', editor );
        } }
        onFocus={ ( event, editor ) => {
            console.log( 'Focus.', editor );
        } }
      />
  )
}

2、动态导入的Form组件

"use client"

import React from "react";
import { CustomCkEditor } from "@/components/app/custom-ckeditor";
import { Input } from "@/components/ui/input"
import { Label } from "@/components/ui/label"

export function ReleaseForm(props: {}) 
{

  const [title, setTitle] = React.useState("");
  const [content, setContent] = React.useState("");
  
  const buildCkEditor = () => {
    return (
      <div className="release-ckeditor w-full overflow-visible text-black">
        <CustomCkEditor data={content} onChange={(data: string)=>setContent(data)}/>
      </div>
    )
  }

  const handleSubmit = () => {
    
  }

  return (
    <>
      <div className="mx-auto mt-5 lg:w-4/5 overflow-visible p-10 bg-white dark:bg-gray-900">
        <div className="text-lg font-bold">发布帖子</div>
        <div className="w-full mt-5">
          <Label className=" text-base ">标题 <span className="ml-2 text-xs">(最多60字)</span></Label>
          <Input value={title} placeholder="请输入标题" className="mt-1 focus-visible:ring-0" onChange={(e)=>{setTitle(e.target.value)}}/>
          <div className="h-4 text-red-600 text-xs mt-1"></div>
        </div>
 
        <Label className=" text-base">内容</Label>
        <div className=" h-1"></div>
        {
          buildCkEditor()
        }

        <div className="w-full text-center">
          <Button className="mt-8 w-28" onClick={handleSubmit}>提交</CustomButton>
        </div>
      </div>
    </>
  )
}

3、导入Form、禁用ssr

"use client"
import React from "react";
import { Input } from "@/components/ui/input"
import { Label } from "@/components/ui/label"
import { CustomButton } from "@/components/app/custom-button";
import { ReleasePropsDialog } from "./(components)/release-props-dialog";

import dynamic from 'next/dynamic'
import { KeyPair } from "@/define/type";
//import { ReleaseForm } from "./(components)/release-form";

export default function ForumReleasePage({ params }: { params: { topic: string } }) {
  
  //动态导入，禁用ssr，否则报错ReferenceError: self is not defined
  const ReleaseForm = dynamic(() => import('./(components)/release-form').then((mod) => mod.ReleaseForm), { ssr: false })

  return (
    <>
      <ReleaseForm/>
    </>
  )
}

注意：这里之所以把所有表单界面和表单业务操作封装到ReleaseForm组件内，是因为测试发现如果只是直接动态导入CustomCkEditor，当绑定的内容改变，动态组件就会重新加载刷新出现闪烁现象
