TikzJax Support

TikZJax converts script tags (containing TikZ code) into SVGs.Therefore, we do not need to refactor tikz, we only need to support tikzjax so that everyone can use various plugins (such as chemfig, which is essential for organic chemistry)

There is also a project called Node-TikZJax
--A port of TikZJax runs on pure Node.js and WebAssembly.
Node-TikZJax lets you render LaTeX and TikZ diagrams to SVG images without the need to install LaTeX toolchain to the environment. You can render graphs, figures, circuits, chemical diagrams, commutative diagrams, and more.

In conclusion, support for tikz is very important and many people need it.

The issue names TikZJax script tags and Node-TikZJax, but no KaTeX files, tests, or entry point. Compare those integration paths first, then define the supported TikZJax behavior and tests that demonstrate SVG output and compatibility with plugins such as chemfig.
