Quill Setup

Setup

Step 1: Add Comment components

Add the Velt Comments component to the root of your app.
This component is required to render comments in your app.
Set the text mode prop to false to hide the default text comment tool.

React / Next.js
Other Frameworks

<VeltProvider apiKey="API_KEY">
  <VeltComments textMode={false} />
</VeltProvider>

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

Step 2: Install the Velt Quill extension

npm i @veltdev/quill-velt-comments

Step 3: Configure the Quill editor with the Velt Comments module

React / Next.js
Other Frameworks

import { useEffect, useRef, useState } from 'react';
import Quill from 'quill';
import { QuillVeltComments } from '@veltdev/quill-velt-comments';

// Register the module with Quill (once, outside component)
Quill.register('modules/veltComments', QuillVeltComments);

function QuillEditor() {
  const editorRef = useRef(null);
  const [quill, setQuill] = useState(null);

  useEffect(() => {
    if (!editorRef.current) return;

    const quillInstance = new Quill(editorRef.current, {
      theme: 'snow',
      modules: {
        veltComments: {
          persistVeltMarks: true,
        },
      },
    });

    setQuill(quillInstance);
  }, []);

  return <div ref={editorRef} />;
}

import Quill from 'quill';
import { QuillVeltComments } from '@veltdev/quill-velt-comments';

// Register the module with Quill
Quill.register('modules/veltComments', QuillVeltComments);

// Create editor with the module enabled
const quill = new Quill('#editor', {
  theme: 'snow',
  modules: {
    veltComments: {
      persistVeltMarks: true,
    },
  },
});

Step 4: Add a comment button to your Quill editor

Add a button that users can click to add comments after selecting text.

When clicking a button, the browser moves focus to the button which clears the editor selection. You must save the selection on mousedown (before focus changes) and restore it before adding the comment.

React / Next.js
Other Frameworks

import { useCallback, useRef } from 'react';
import { addComment } from '@veltdev/quill-velt-comments';

// Inside your QuillEditor component from Step 3:
const savedSelectionRef = useRef(null);

const handleAddComment = useCallback(() => {
  if (quill) {
    if (savedSelectionRef.current) {
      quill.setSelection(savedSelectionRef.current.index, savedSelectionRef.current.length);
    }
    addComment({ editor: quill });
    savedSelectionRef.current = null;
  }
}, [quill]);

// In your JSX:
<button
  onMouseDown={(e) => {
    e.preventDefault();
    const sel = quill?.getSelection();
    if (sel?.length > 0) savedSelectionRef.current = sel;
  }}
  onClick={handleAddComment}
>
  Add Comment
</button>

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

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

let savedSelection = null;
const btn = document.getElementById('add-comment-btn');

btn.addEventListener('mousedown', () => {
  const sel = quill.getSelection();
  if (sel && sel.length > 0) savedSelection = sel;
});

btn.addEventListener('click', () => {
  if (savedSelection) quill.setSelection(savedSelection.index, savedSelection.length);
  addComment({ editor: quill });
  savedSelection = null;
});

Unlike Tiptap, Quill does not have a built-in bubble menu. You will need to create your own comment button or toolbar item.

Step 5: Call `addComment` to add a comment

Call this method to add a comment to selected text in the Quill editor. You can use this when the user clicks on the comment button or presses a keyboard shortcut.
Params: AddCommentRequest. It has the following properties:
- editor: Instance of the Quill editor.
- editorId: Id of the Quill editor. Use this if you have multiple Quill editors on the same page. (optional)
- context: Add any custom metadata to the Comment Annotation. Learn more. (optional)

React / Next.js
Other Frameworks

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

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

addComment(addCommentRequest);

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

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

addComment(addCommentRequest);

Step 6: Render comments in Quill editor

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

React / Next.js
Other Frameworks

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

const annotations = useCommentAnnotations();

useEffect(() => {
  if (quill && annotations?.length) {
    const renderCommentsRequest = {
      editor: quill,
      editorId: 'EDITOR_ID',
      commentAnnotations: annotations,
    };
    renderComments(renderCommentsRequest);
  }
}, [quill, annotations]);

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

const commentElement = Velt.getCommentElement();
commentElement.getAllCommentAnnotations().subscribe((annotations) => {
  if (quill && annotations?.length) {
    const renderCommentsRequest = {
      editor: quill,
      editorId: 'EDITOR_ID',
      commentAnnotations: annotations,
    };
    renderComments(renderCommentsRequest);
  }
});

Step 7: Persist Velt Comment Marks (optional)

By default, Velt comment marks (<velt-comment-text>) are persisted by the Velt SDK. When the editor loads and the Velt SDK initializes, the marks will be automatically added to the editor.
If you plan to store the contents of the Quill editor on your end with the comment marks already included, you can disable this feature.
Default: true

const quill = new Quill(editorRef.current, {
  theme: 'snow',
  modules: {
    veltComments: {
      persistVeltMarks: false,
    },
  },
});

Step 8: Style the commented text

You can style the commented text by adding CSS for the velt-comment-text element.

velt-comment-text {
  background-color: rgba(255, 255, 0, 0.3);
  border-bottom: 2px solid #ffcc00;
  cursor: pointer;
}

velt-comment-text:hover {
  background-color: rgba(255, 255, 0, 0.5);
}

velt-comment-text.velt-comment-selected {
  background-color: rgba(255, 255, 0, 0.5);
}
