A quick hack to "embed" MathJax into an html file as SVGs. Actually, it doesn't embed anything, but renders the page in jsdom & prints the result to stdout. The resulting file doesn't require JavaScript to render itself.

$ npm i -g mathjax-embed
$ mathjax-embed -V
mathjax-embed/s (2.0.0 Linux) mathjax/x86_64 domjs/4.0.0 nodejs/27.0.0 v22.20.0

Usage

Convert an html chunk to a standalone html file:

echo '<p>Function $y = \sin(x)$.</p>' | mathjax-embed > 1.html

A markdown file with TeX formulas:

$ pandoc -s test/data/example02.md -t html --mathjax | mathjax-embed > 2.html

In the default pandoc (3.8.1) configuration, the math delimiters are $$...$$ for displayed mathematics, and $...$ for in-line.

Run mathjax-embed --config-print to print the default mathjax configuration. Use -c file.json option to provide your own.
