TinyMCE Setup

The TinyMCE integration renders comment highlights as view-only overlay elements positioned over the commented text. It does not modify your TinyMCE content, schema, undo history, or saved HTML.

Setup

Step 1: Add Comment components

Add the Velt Comments component to the root of your app. This component is required to create and render comments in your app.
Authenticate the user with authProvider and set the Velt document before users add comments.
Set the textMode prop to false to hide the default Velt text comment tool. TinyMCE selections are handled by @veltdev/tinymce-velt-comments.
Add VeltCommentsSidebar if you want a Google Docs-style comment sidebar.

React / Next.js
Other Frameworks

import { VeltComments, VeltCommentsSidebar, VeltProvider, useSetDocument } from '@veltdev/react';

const user = {
  userId: 'user-1',
  organizationId: 'org-1',
  name: 'User One',
  email: 'user@example.com',
};

function VeltSetup() {
  useSetDocument('document-id', { documentName: 'Document name' });
  return null;
}

function App() {
  return (
    <VeltProvider apiKey="API_KEY" authProvider={{ user }}>
      <VeltSetup />
      <VeltComments textMode={false} />
      <VeltCommentsSidebar />
      {/* Your app content */}
    </VeltProvider>
  );
}

<body>
  <velt-comments text-mode="false"></velt-comments>
</body>

Step 2: Install the Velt TinyMCE extension

React / Next.js
Other Frameworks

npm i @veltdev/tinymce-velt-comments @tinymce/tinymce-react tinymce

npm i @veltdev/tinymce-velt-comments @veltdev/client tinymce

tinymce is a peer dependency and must be provided by your TinyMCE app. Import the self-hosted TinyMCE assets used by your editor so @tinymce/tinymce-react and the Velt plugin use the same TinyMCE instance.

Step 3: Configure the TinyMCE editor with the Velt Comments plugin

Add VeltCommentsPlugin to the TinyMCE plugins list and set velt_comments_editor_id in the editor init options. Capture the TinyMCE editor instance from onInit or the init event, then render Velt comment annotations into the editor with renderComments.

React / Next.js
Other Frameworks

import { useEffect, useState } from 'react';
import { Editor as TinyMCEReact } from '@tinymce/tinymce-react';
import { useCommentAnnotations } from '@veltdev/react';
import type { Editor as TinyMCEEditor } from 'tinymce';
import { VeltCommentsPlugin, renderComments } from '@veltdev/tinymce-velt-comments';

import 'tinymce';
import 'tinymce/icons/default';
import 'tinymce/themes/silver';
import 'tinymce/models/dom';
import 'tinymce/plugins/lists';
import 'tinymce/plugins/link';
import 'tinymce/skins/ui/oxide/skin.min.css';
import contentUiCss from 'tinymce/skins/ui/oxide/content.min.css?raw';
import contentCss from 'tinymce/skins/content/default/content.min.css?raw';

const EDITOR_ID = 'my-editor';

function TinyMCEEditor() {
  const [editor, setEditor] = useState<TinyMCEEditor | null>(null);
  const annotations = useCommentAnnotations();

  useEffect(() => {
    if (!editor) return;

    renderComments({
      editor,
      editorId: EDITOR_ID,
      commentAnnotations: annotations ?? [],
    });
  }, [editor, annotations]);

  return (
    <TinyMCEReact
      licenseKey="gpl"
      initialValue="<p>Select text, then add a comment.</p>"
      init={{
        license_key: 'gpl',
        skin: false,
        content_css: false,
        content_style: `${contentUiCss}\n${contentCss}`,
        plugins: ['lists', 'link', VeltCommentsPlugin],
        toolbar: 'undo redo | bold italic | bullist numlist | link | addveltcomment',
        velt_comments_editor_id: EDITOR_ID,
      }}
      onInit={(_event, nextEditor) => setEditor(nextEditor)}
    />
  );
}

import tinymce from 'tinymce';
import { VeltCommentsPlugin } from '@veltdev/tinymce-velt-comments';

let editor;

tinymce.init({
  selector: '#editor',
  license_key: 'gpl',
  plugins: [VeltCommentsPlugin],
  toolbar: 'undo redo | bold italic | addveltcomment',
  velt_comments_editor_id: 'my-editor',
  setup: (nextEditor) => {
    nextEditor.on('init', () => {
      editor = nextEditor;
    });
  },
});

The package registers a TinyMCE plugin named veltcomments. You can pass the exported VeltCommentsPlugin constant in plugins, or use the string 'veltcomments' after the package has been imported. It also registers a TinyMCE toolbar button named addveltcomment.

Step 4: Add a comment button to your TinyMCE editor

Add a button that users can click to add comments after selecting text in the TinyMCE editor. Important: Use onMouseDown with preventDefault() so the browser does not move focus away from the editor before addComment reads the current selection. Keep the actual addComment call in onClick.

React / Next.js
Other Frameworks

import { addComment } from '@veltdev/tinymce-velt-comments';

const handleAddComment = () => {
  if (!editor) return;

  void addComment({
    editor,
    editorId: EDITOR_ID,
  });
};

<button
  onMouseDown={(event) => event.preventDefault()}
  onClick={handleAddComment}
>
  Add Comment
</button>

<button id="add-comment">Add Comment</button>
<div id="editor"></div>

import { addComment } from '@veltdev/tinymce-velt-comments';

const addCommentButton = document.querySelector('#add-comment');

addCommentButton.addEventListener('mousedown', (event) => {
  event.preventDefault();
});

addCommentButton.addEventListener('click', () => {
  void addComment({ editor, editorId: 'my-editor' });
});

Step 5: Call `addComment` to add a comment

Call this method to add a comment to selected text in the TinyMCE editor.
Params: AddCommentRequest. It has the following properties:
- editor: TinyMCE Editor instance.
- editorId: Id of the editor. Use this if you have multiple TinyMCE editors on the same page. (optional)
- context: Add custom metadata to the Comment Annotation. Learn more. (optional)

React / Next.js
Other Frameworks

import { addComment } from '@veltdev/tinymce-velt-comments';

const addCommentRequest = {
  editor,
  editorId: 'EDITOR_ID',
  context: {
    storyId: 'story-id',
    storyName: 'story-name',
  },
};

void addComment(addCommentRequest);

import { addComment } from '@veltdev/tinymce-velt-comments';

const addCommentRequest = {
  editor,
  editorId: 'EDITOR_ID',
  context: {
    storyId: 'story-id',
    storyName: 'story-name',
  },
};

void addComment(addCommentRequest);

The library automatically writes context.textEditorConfig with the selected text, its 1-based occurrence index in the document, and the editor ID when one is provided. If the editor is inside an element with data-velt-location-id, that value is sent to Velt as the annotation location.

Step 6: Render comments in TinyMCE editor

Get the comment data from Velt SDK and render it in the TinyMCE editor.
Params: RenderCommentsRequest. It has the following properties:
- editor: TinyMCE Editor instance.
- editorId: Id of the editor. Use this if you have multiple TinyMCE editors on the same page. (optional)
- commentAnnotations: Array of Comment Annotation objects.

React / Next.js
Other Frameworks

import { useEffect } from 'react';
import { useCommentAnnotations } from '@veltdev/react';
import { renderComments } from '@veltdev/tinymce-velt-comments';

const commentAnnotations = useCommentAnnotations();

useEffect(() => {
  if (!editor) return;

  renderComments({
    editor,
    editorId: 'EDITOR_ID',
    commentAnnotations: commentAnnotations ?? [],
  });
}, [editor, commentAnnotations]);

import { renderComments } from '@veltdev/tinymce-velt-comments';

const commentElement = Velt.getCommentElement();
commentElement.getAllCommentAnnotations().subscribe((annotations) => {
  renderComments({
    editor,
    editorId: 'EDITOR_ID',
    commentAnnotations: annotations,
  });
});

renderComments filters annotations by context.textEditorConfig.editorId. Resolved comments with status.type === 'terminal' are hidden unless they are currently selected in Velt.

Step 7: Re-apply TinyMCE comment highlights (optional)

TinyMCE renders comment highlights as view-only overlay elements in the outer document.
The integration does not write Velt comment marks into your TinyMCE content or undo history.
Save your TinyMCE content normally. After you recreate the editor or replace content with editor.setContent(...), call renderComments again.

const html = editor.getContent();
// Save html to your backend.

renderComments({
  editor,
  editorId: 'EDITOR_ID',
  commentAnnotations,
});

Step 8: Style the commented text

You can style the commented text by adding CSS for the velt-comment-text element.
TinyMCE highlights are overlay elements in the outer document, not inside the editor iframe, so add this CSS to your page stylesheet instead of content_style.

velt-comment-text {
  background-color: rgba(255, 212, 0, 0.4);
  border-bottom: 2px solid #ffd400;
  cursor: pointer;
}

velt-comment-text:hover {
  background-color: rgba(255, 212, 0, 0.6);
}

velt-comment-text[comment-selected="true"],
velt-comment-text.velt-comment-selected {
  background-color: rgba(255, 212, 0, 0.7);
}

Using TinyMCE without React

For a vanilla TinyMCE app, initialize Velt with @veltdev/client, add the Velt comments web component to the page, and subscribe to annotations through the Velt comment element.

npm install @veltdev/client

<velt-comments text-mode="false"></velt-comments>
<button id="add-comment-btn">Add Comment</button>
<div id="editor"></div>

import { initVelt } from '@veltdev/client';
import tinymce from 'tinymce';
import {
  VeltCommentsPlugin,
  addComment,
  renderComments,
} from '@veltdev/tinymce-velt-comments';

const EDITOR_ID = 'my-editor';

const velt = await initVelt('YOUR_API_KEY');

await velt.identify({
  userId: 'user-1',
  organizationId: 'org-1',
  name: 'User One',
  email: 'user@example.com',
});

velt.setDocument('document-id', { documentName: 'Document name' });

const [editor] = await tinymce.init({
  selector: '#editor',
  license_key: 'gpl',
  plugins: [VeltCommentsPlugin],
  toolbar: 'bold italic | addveltcomment',
  velt_comments_editor_id: EDITOR_ID,
});

document.getElementById('add-comment-btn')?.addEventListener('mousedown', (event) => {
  event.preventDefault();
});

document.getElementById('add-comment-btn')?.addEventListener('click', () => {
  void addComment({ editor, editorId: EDITOR_ID });
});

velt.getCommentElement()?.getAllCommentAnnotations().subscribe((annotations) => {
  renderComments({ editor, editorId: EDITOR_ID, commentAnnotations: annotations });
});

Multiple TinyMCE editors

When using multiple editors on the same page, provide a unique editorId to TinyMCE’s velt_comments_editor_id init option, addComment, and renderComments.

const [editor1] = await tinymce.init({
  target: document.querySelector('#editor-1') as HTMLElement,
  license_key: 'gpl',
  plugins: [VeltCommentsPlugin],
  toolbar: 'addveltcomment',
  velt_comments_editor_id: 'editor-1',
});

const [editor2] = await tinymce.init({
  target: document.querySelector('#editor-2') as HTMLElement,
  license_key: 'gpl',
  plugins: [VeltCommentsPlugin],
  toolbar: 'addveltcomment',
  velt_comments_editor_id: 'editor-2',
});

await addComment({ editor: editor1, editorId: 'editor-1' });
await addComment({ editor: editor2, editorId: 'editor-2' });

renderComments({
  editor: editor1,
  editorId: 'editor-1',
  commentAnnotations,
});

renderComments({
  editor: editor2,
  editorId: 'editor-2',
  commentAnnotations,
});

TypeScript support

The package includes TypeScript definitions. Key type exports:

import type {
  AddCommentRequest,
  RenderCommentsRequest,
  TinymceVeltCommentsConfig,
  CommentAnnotationContext,
} from '@veltdev/tinymce-velt-comments';
import type { CommentAnnotation } from '@veltdev/types';

Runtime exports:

import {
  VeltCommentsPlugin,
  registerVeltCommentsPlugin,
  addComment,
  renderComments,
} from '@veltdev/tinymce-velt-comments';

Complete Example

APIs

VeltCommentsPlugin

The registered TinyMCE plugin name ('veltcomments') that powers Velt comments. Importing the library registers it; add it to the TinyMCE editor’s plugins list. Init options:

velt_comments_editor_id?: string - Unique identifier for this editor instance.
velt_comments_persist_marks?: boolean - Reserved for API parity; highlights are always rendered as view-only overlays.

React / Next.js
Other Frameworks

import { VeltCommentsPlugin } from '@veltdev/tinymce-velt-comments';

<TinyMCEReact
  licenseKey="gpl"
  init={{
    license_key: 'gpl',
    plugins: ['lists', 'link', VeltCommentsPlugin],
    toolbar: 'bold italic | addveltcomment',
    velt_comments_editor_id: 'my-editor',
  }}
/>

import { VeltCommentsPlugin } from '@veltdev/tinymce-velt-comments';

tinymce.init({
  selector: '#editor',
  license_key: 'gpl',
  plugins: [VeltCommentsPlugin],
  toolbar: 'bold italic | addveltcomment',
  velt_comments_editor_id: 'my-editor',
});

registerVeltCommentsPlugin()

Explicitly registers the veltcomments plugin with a TinyMCE instance. Importing the package auto-registers the plugin when a TinyMCE instance is available; use this method when TinyMCE is loaded or provided later. Parameters:

instance?: TinyMCE - TinyMCE instance to register against.

Returns: void

import tinymce from 'tinymce';
import { registerVeltCommentsPlugin } from '@veltdev/tinymce-velt-comments';

registerVeltCommentsPlugin(tinymce);

addComment()

Creates a Velt comment annotation for the currently selected TinyMCE text.

Signature: async (request: AddCommentRequest) => Promise<void>
Params: request: AddCommentRequest
Returns: Promise<void>

React / Next.js
Other Frameworks

import { addComment } from '@veltdev/tinymce-velt-comments';

const handleAddComment = () => {
  if (!editor) return;

  Comment
</button>

import { addComment } from '@veltdev/tinymce-velt-comments';

void addComment({
  editor,
  editorId: 'my-editor',
  context: { customData: 'value' },
});

renderComments()

Resolves Velt comment annotations back to TinyMCE DOM ranges and renders stable <velt-comment-text> overlay elements for the visible comments.
