How to run renderMathInElement without the CDN?

I’m building an electron app so I don’t want to use the CDN. Is there any way around this?

Secondly, how do I render a math block with multiple lines of code? the documentation only gives an example of rendering one like of code.

I tried rendering this,

\begin{vmatrix}
   a & b \\
   c & d
\end{vmatrix}

but the following does’t work.

        katex.render("\begin{vmatrix} a & b \\ c & d\end{vmatrix}", theorem, {
            throwOnError: false,
            displayMode: true
    });

If you’re using a build system like webpack or parcel you should be able to do

import katex from "katex";
import "katex/dist/katex.min.css";
import renderMathInElement from "katex/dist/contrib/auto-render.js";

in one of your source files. With webpack you’ll need to set up css-loader for this to work properly. While I’ve done this for just KaTeX, I haven’t tried this for auto-render yet.
