Cybersecurity Policy Document Editor (React + Next.js)

A proof-of-concept web app that shows how a cybersecurity policy (for example an Information Security Policy) can be authored, validated, reviewed and exported inside the browser with the Syncfusion React Document Editor.

On start-up the app generates a complete, styled policy document (title page, table of contents, seven policy sections, header and footer with page numbers). A side panel then exposes programmatic operations on that document:

• Word-like editing, with DOCX and PDF export
• Template-based content insertion
• Content extraction, search and compliance validation
• Comments and track changes for review and approval

Tech stack: Next.js (App Router), React, TypeScript, @syncfusion/ej2-react-documenteditor, @syncfusion/ej2-pdf-export, Syncfusion Tailwind 3 theme.

Features

All snippets come from app/Editor.tsx and app/policy.ts. In them, editor() is shorthand for container.current!.documentEditor.

1. Setup and license registration

The Document Editor container is registered with its toolbar module. The Syncfusion license key is read from an environment variable.

registerLicense(process.env.NEXT_PUBLIC_SYNCFUSION_LICENSE_KEY ?? '');
DocumentEditorContainerComponent.Inject(Toolbar);

2. Policy generation from a template

SECTIONS in policy.ts is a map of section title to body text. generatePolicy opens a blank document and builds the title, table of contents, sections, header and footer. It runs automatically when the editor is created.

<DocumentEditorContainerComponent
  ref={container}
  height="100%"
  enableToolbar={true}
  created={() => generatePolicy(editor())}
  serviceUrl="https://document.syncfusion.com/web-services/docx-editor/api/documenteditor/"
/>

export function generatePolicy(editor: DocumentEditor) {
  editor.openBlank();
  applyStyle(editor, 'Title');
  editor.editor.insertText('Information Security Policy');
  // ... table of contents, page breaks, sections
  Object.keys(SECTIONS).forEach((title) => insertSection(editor, title));
  editor.editor.updateToc();

  editor.selection.goToFooter();
  editor.editor.insertText('Confidential | Version 1.0 | Page ');
  editor.editor.insertPageNumber();
  editor.editor.insertText(' of ');
  editor.editor.insertPageCount();
}

3. Insert individual sections

One button is generated per entry in SECTIONS. Each appends a Heading 1 plus body paragraph at the end of the document. applyStyle creates built-in styles (Title, Heading 1) when the blank document lacks them.

export function insertSection(editor: DocumentEditor, title: string) {
  editor.selection.moveToDocumentEnd();
  applyStyle(editor, 'Heading 1');
  editor.editor.insertText(title);
  editor.editor.onEnter();
  applyStyle(editor, 'Normal');
  editor.editor.insertText(SECTIONS[title]);
  editor.editor.onEnter();
}

Available sections: Scope, Purpose, Responsibilities, Access Control Policy, Incident Response Policy, Compliance Requirements, Review Cycle.

4. Save as DOCX, export to PDF, print, update TOC

DOCX is saved with the built-in API. PDF is built client-side by rendering each page to an image and placing it on a PDF page.

editor().save('Information Security Policy', 'Docx');

const exportPdf = async () => {
  const pdf = new PdfDocument();
  pdf.pageSettings.margins.all = 0;
  for (let i = 1; i <= editor().pageCount; i++) {
    const image = editor().exportAsImage(i, 'Jpeg');
    await new Promise((resolve) => (image.onload = resolve));
    const page = pdf.pages.add();
    const { width, height } = page.getClientSize();
    page.graphics.drawImage(new PdfBitmap(image.src.replace('data:image/jpeg;base64,', '')), 0, 0, width, height);
  }
  pdf.save('Information Security Policy.pdf');
};

editor().print();
editor().editor.updateToc();

5. Read content

Selects the whole document, reads the text, and reports word count and serialized (SFDT) size.

editor().selection.selectAll();
const text = editor().selection.text;
const words = text.split(/\s+/).filter(Boolean).length;
const sfdtLength = editor().serialize().length;

6. Search and policy validation

Search looks for key terms. Validation checks that required sections exist and shows ✅ or ❌ for each.

const REQUIRED = ['Scope', 'Purpose', 'Responsibilities', 'Incident Response', 'Review Date'];

const found = (term: string) => {
  editor().search.findAll(term);
  const count = editor().search.searchResults.length;
  editor().search.searchResults.clear();
  return count > 0;
};

const validate = () =>
  setOutput(['Policy Validation Result', ...REQUIRED.map((t) => `${found(t) ? '✅' : '❌'} ${t}`)]);

7. Comments

Add a comment at the current selection and summarize open versus resolved comments.

editor().editor.insertComment(text);

const comments = editor().getComments();
const resolved = comments.filter((c) => c.commentProperties?.isResolved).length;
// `${comments.length - resolved} Open Comments`, `${resolved} Resolved Comments`

8. Versioning and approval (track changes)

Toggle track changes, move between revisions, and accept or reject them.

editor().enableTrackChanges = !trackChanges;
editor().selection.navigatePreviousRevision();
editor().selection.navigateNextRevision();
editor().revisions.acceptAll();
editor().revisions.rejectAll();

How to Run the Sample

Prerequisites

• Node.js 18.18 or later (Node 20+ recommended) and npm
• A Syncfusion license key. You can get a free Community License or a trial key. Without one, the editor shows a license banner.

Steps

1. Install dependencies:

   npm install

2. Create your environment file and add your license key:

   cp .env.example .env.local

   NEXT_PUBLIC_SYNCFUSION_LICENSE_KEY=your_license_key_here

3. Start the development server:

   npm run dev

4. Open http://localhost:3000. The policy document loads automatically and the left panel shows the actions.

Production build

npm run build
npm start

Notes

• Operations that require server-side processing, such as file imports, use Syncfusion's public demo service configured through the serviceUrl property in Editor.tsx. For production environments, host your own Document Editor web service and update the serviceUrl accordingly. For more information, refer to the documentation: Import in React DOCX Editor | Syncfusion.
• Dependencies are declared as * / latest. Pin versions in package.json for reproducible builds.

Suggested walkthrough

1. Click Validate Policy to confirm the required sections exist.
2. Click Track Changes: Off to turn it on, edit some text, then use Next Revision and Accept All.
3. Select text, click Add Comment, then Comment Summary.
4. Click Save DOCX or Export PDF to download the result.
