@jupyter-kit/mathjax-cdn

MathJax loaded from a CDN at runtime. Tiny bundle (~1KB gz); the actual MathJax SVG renderer (~600KB) is fetched from jsdelivr the first time a math cell renders.

Install

pnpm add @jupyter-kit/mathjax-cdn @jupyter-kit/core

Usage

import { createMathjaxCdnPlugin } from '@jupyter-kit/mathjax-cdn';

createRenderer({
  plugins: [createMathjaxCdnPlugin()],
});

How it works

• remark-math tokenises $...$ early so markdown escape processing can't mangle the LaTeX source.
• A small rehype plugin re-wraps math nodes back into bare $…$ text so MathJax's auto-render finds them.
• The CDN script (mathjax@3/es5/tex-svg.js) is injected once into document.head; subsequent cells reuse it via MathJax.typesetPromise.

Options

createMathjaxCdnPlugin({
  src: 'https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-svg.js', // default
  config: { /* full window.MathJax config (overrides our defaults) */ },
  forceReload: false,
});
