I followed this good tutorial on how to add \(\KaTeX\) to hugo.
Here is an example showing that KaTeX (should) now work. $$\int_{a}^{b} x^2 dx$$
Here are some remarks I have about the original tutorial.
Auto-rendering
Add the following script in the footer
<script defer src="https://cdn.jsdelivr.net/npm/katex@0.10.0-rc.1/dist/contrib/auto-render.min.js" integrity="sha384-yACMu8JWxKzSp/C1YV86pzGiQ/l1YUfE8oPuahJQxzehAjEt2GiQuy/BIvl9KyeF" crossorigin="anonymous" onload="renderMathInElement(document.body);"></script>This will activate the auto rendering
Other remarks
-
{{ end }}is unnecessary, only write the following to include thekatex.htmlpartial.{{ partial "katex.html" . }} - \(\KaTeX\) actually works also with
.orgfiles ! For inline math, you will need to use\( KaTeX \)rather than$$KaTeX$$or$KaTeX$, which seem not to work yet katex: trueis not necessary
