Support for math-blocks with Katex/MathJax

Hi, I think Retype would be well suited to create websites about mathematical topics, but for that to be feasible it would need proper support for some kind of HTML Math rendering, of which I couldn't find any documentation or examples for (so I assume it's not supported as of yet). The two most popular in that area would be Katex and MathJax (although I personally much prefer Katex). Would it be possible to include support for these?

Being able to do something like $s_n = \sum_{k = 0}^{n} a_k$ inside the markdown source and get a nice Katex-rendered math formula in the website would be a great addition I believe.

Thanks for the feature request. We should be able to easily add MathJax. We've had an open issue for MathJax for a while, so I'm not sure why we haven't added this integration already. The work required for us to add MathJax integration will be almost identical to the recently added Mermaid diagraming library.

Katex might take a little more work. They have a nice pre-rendering feature that would be good for Retype to take advantage of, then the diagrams could be pre-rendered during the Retype build phase instead of repeatedly on the client.

We will investigate and try our best to get them both into the v1.9.0 release.

KaTex support has been added to Retype and will be included in the upcoming v1.10.0 release.

Both inline and block syntax will now be possible:
