Quick start

First, install the build from npm:

npm install --save ckeditor5-build-classic-dna

Use CKEditor as React component:

import React, { Component } from "react";
import PropTypes from "prop-types";
import { CKEditor } from "@ckeditor/ckeditor5-react"; //starting from ckeditor5-react v3, we should use { CKEditor }
// import CKEditor from "@ckeditor/ckeditor5-react"; // for ckeditor5-react v2
import ClassicEditor from "ckeditor5-build-classic-dna";

class CKEditor5 extends Component {
  static get propTypes() {
    return {
      value: PropTypes.string,
      onChange: PropTypes.func,
    };
  }

// NOTE: You can customize toolbar using "config", here are avaliable Toolbar Items:
// "heading",
// "bold",
// "italic",
// "link",
// "bulletedList",
// "numberedList",
// "indent",
// "outdent",
// "insertImage",
// “insertImageFromUnsplash”,
// "code",
// "codeBlock",
// "blockQuote",
// "insertTable",
// "mediaEmbed",
// "undo",
// "redo"

  render() {
    return (
      <CKEditor
        editor={ClassicEditor}
        config={{
          table: {
            customClass: ["ui", "table", "celled"], // Important!!! need to be array
          },
          image: {
          	customClass: ["ui", "fluid", "image"], // Use whatever class names defined in your theme
          },
          toolbar: [
            "heading",
            "|",
            "bold",
            "italic",
            "link",
            "bulletedList",
            "numberedList",
            "|",
            "indent",
            "outdent",
            "|",
            "codeBlock",
            "blockQuote",
            "insertTable",
            "mediaEmbed",
            "undo",
            "redo",
          ],
        data={this.props.value}
        onInit={(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();
          this.props.onChange(data);
        }}
      />
    );
  }
}
export default CKEditor5;

Or use it in your website:

<div id="editor">
  <p>This is the editor content.</p>
</div>
<script src="./node_modules/ckeditor5-build-classic-dna/build/ckeditor.js"></script>
<script>
  ClassicEditor.create(document.querySelector("#editor"))
    .then((editor) => {
      window.editor = editor;
    })
    .catch((error) => {
      console.error("There was a problem initializing the editor.", error);
    });
</script>

Or in your JavaScript application:

import ClassicEditor from "ckeditor5-build-classic-dna";

// Or using the CommonJS version:
// const ClassicEditor = require( 'ckeditor5-build-classic-dna' );

ClassicEditor.create(document.querySelector("#editor"))
  .then((editor) => {
    window.editor = editor;
  })
  .catch((error) => {
    console.error("There was a problem initializing the editor.", error);
  });

Or in React With SSR (for example: NextJS)

import { useState } from "react";
// For SSR, you cannot import CKEditor directly since it needs client functions to run.
// import CKEditor from "components/Common/CKEditor";
import dynamic from "next/dynamic";
const CKEditor = dynamic(() => import("components/Common/CKEditor"), {
  ssr: false,
});

const CKEditorDemo = () => {
  const [content, setContent] = useState("");
  return <CKEditor value={content} onChange={setContent} />;
};

export default CKEditorDemo;
