[tw5] Anyone Currently Using MathJax with node.js TW

[Kevin Kleinfelter]

Is anyone *currently* using MathJax with the *current* node.js TW? What's
the secret sauce?

When I try http://mathjax-tw5.kantorsite.net/ directly, I get proper
rendering but also an error "Uncaught TypeError: Failed to execute
'observe' on 'MutationObserver': parameter 1 is not of type 'Node'."

When I try https://gist.github.com/kpe/cc0547b318e6f8d4ddaa, I get no
render and "Uncaught TypeError: Failed to execute 'observe' on
'MutationObserver': parameter 1 is not of type 'Node'."

When I try https://gist.github.com/kpe/cc0547b318e6f8d4ddaa plus the fix
suggested in its comments, I get no render and "TypeError: Argument 1
('target') to MutationObserver.observe must be an instance of Node."

TIA

Found a solution:

Use https://gist.github.com/kpe/cc0547b318e6f8d4ddaa
<https://www.google.com/url?q=https%3A%2F%2Fgist.github.com%2Fkpe%2Fcc0547b318e6f8d4ddaa&sa=D&sntz=1&usg=AFQjCNG6AVXYgHyCgA_mwRM_T5ViKSkyqA> plus
the fix suggested in its comments. He describes two ways to install it.
The trick is to use the manually-created files in the plugins directory,
not to create a startup tiddler. It looks to me like maybe there are no
tc-story-river nodes at the time the code is executed as a startup tiddler.

Just out of interest what advantage/ difference is there using mathjax over the katex plugin?

TiddlyWiki switched to katex, since it is 100% offline.

The other factor is that MathJax only runs in the browser, and so can’t be used (for example) under Node.js to generate static HTML pages.

Best wishes
