[phongyewtong]

I was trying to import the package that i download from online builder. Am i doing it correctly? How should I import it?

1. npm install from the folder.
2. npm build from the folder.

Error: Module not found: Can't resolve 'ckeditor5-custom-build'

import Editor from 'ckeditor5-custom-build';

Error: Attempted import error: 'ckeditor5-custom-build/build/ckeditor' does not contain a default export (imported as 'Editor').

import Editor from 'ckeditor5-custom-build/build/ckeditor';

import React, { Component, Fragment, useEffect } from 'react';
import CKEditor from '@ckeditor/ckeditor5-react';
// import ClassicEditor from '@ckeditor/ckeditor5-build-classic';
import Editor from '../../ckeditor5/build/ckeditor';
// import Base64UploadAdapter from '@ckeditor/ckeditor5-upload/src/adapters/base64uploadadapter';

const TEditor = ({onEditorStateChange, defaultValue}) => {
    const onChange = (event, editor ) => {
      const data = editor.getData();
      console.log(  data  );
      onEditorStateChange(data)
    };

    const onBlur = (event, editor) => {
      console.log( 'Blur.', editor );
    };

    const onFocus = (event, editor) => {
      console.log( 'Focus.', editor );
    };

    const onInit = (editor) => {
      console.log( 'Editor is ready to use!', editor );
    };

    const editorConfiguration = {
      plugins: [ 'Base64UploadAdapter' ]
    };

    return (
        <div className="editor">
            {/* <h2>Using CKEditor 5 build in React</h2> */}
            <CKEditor
                editor={Editor}
                config={editorConfiguration}
                data={defaultValue ? defaultValue : ""}
                onInit={onInit}
                onChange={onChange}
                onBlur={onBlur}
                onFocus={onFocus}
            />
        </div>
    );
}

export default TEditor;
