TOAST UI Editor : KaTeX Plugin

This plugin adds KaTeX rendering for $$latex ... $$ blocks and inline $...$ math.

Install

npm install --save @techie_doubts/editor-plugin-katex

Usage

import { Editor } from '@techie_doubts/tui.editor.2026';
import katexPlugin from '@techie_doubts/editor-plugin-katex';

const editor = new Editor({
  el: document.querySelector('#editor'),
  initialEditType: 'markdown',

Notes

• Inline rendering in WYSIWYG uses decoration overlays only (no nodeviews or document mutation).
• KaTeX stylesheet is required for proper rendering.
