Blades natively supports rendering LaTeX formulas into MathML.
Sadly, Chromium-based browsers don’t support it.
This plugin renders the formulas into HTML using KaTeX.
Formulas delimited by
$ are rendered in inline mode and by in display mode.
Be aware there is a Rust version that does the same, but faster.
This plugin can be installed as
yarn global add https://github.com/grego/blades-katex
Then, it can be used in Blades as
[plugins] transform = "blades-katex"
This plugin is basically a stripped-down version of auto-render extension for KaTeX.
