site VS KaTeX

Jumping on the bandwagon of the guy that jumped on the bandwagon, because you mentioned potentially re-doing your own code at some point so might be interested: my personal site [0] looks very much like this (and is also written in Rust), but uses the comrak [1] crate to convert blog posts from Markdown to HTML on the fly before formatting with the header/footer theme. Using comrak lets you write in-line HTML (so you're not stuck with only Markdown syntax if you want to do something fancier like code blocks or ), and the whole site is <100 LoC, including route definitions.

It handled the one potential HN hug-of-death event I've had without issues while running on the smallest DO droplet offered, and has basically been issue-free since I got it up and running.

I want to resolve this KaTeX issue, so in order to test my ideas, is there some LaTeX test file with just a lot of equations, preferably inline (since this issue is related to inline math) but without fancy libraries or stuff not included in KaTeX?

> Could you elaborate on why you switched away from it?

I started using KaTeX sometime after 2015 because it promised to be fast (the fastest! [1]). I had to change the representation of a bunch of expressions because KaTeX didn't support some environments, whilst MathJax did. It was a trade-off I was willing to accept at the time.

Many years later, I started writing a personal static-site generator. I wanted comparatively lightweight pages, so rendering server-side was an option. I re-evaluated MathJax vs KaTeX again and this time I leaned towards MathJax, as speed was no longer an issue for me. It looks like KaTeX has broader support now [2].

Another alternative: Create a WebView by using UIViewRepresentable and Webkit together with MathJax or Katex where Katex is the better option. Here is a link to katex: https://katex.org/

This isn't a LaTeX question. It's a web dev question. Probably best directed at folks who make (or use) KaTeX.

If you want to make it from scratch, go with https://www.slatejs.org/examples/richtext, then use something like https://katex.org/ for rendering the LaTeX, and maybe Mathjs.org for plotting.

The speed of KaTeX is great, but the lack of support for diagrams (a la tikz-cd) is what makes KaTeX unsuitable for general adoption by mathematicians (e.g., mathoverflow.net and all online mathematical wiki I know use MathJax). KaTeX has some rudimentary support for diagrams though the {CD} environment, but something more fully fledged akin to tizk-cd or xymatrix is needed. There's been some discussion on their github (https://github.com/KaTeX/KaTeX/issues/219), but I wouldn't hold my breath.

Haven't personally used it, but have heard of KaTeX
