Hi! I saw you recently added LaTeX support, which is awesome! However, I saw that it was not yet integrated with the Next plugin. I tried my hand at it myself a bit, but couldn't get it to work with the react loader for some reason.

And some other things, such as adding @orgajs/rehype-latex to the package.json.

Building the project and then trying to run the Next starter yields this error.

Let me know if I can do anything more to help!

Sorry about the lack of documentation, I am working on them right now. But I just tried on top of the next example. You don't have to tweak the next plugin for this. You just add it in the next.config.js file, like so:

const latex = require('@orgajs/rehype-latex').default
const withOrga = require('@orgajs/next').default({
  // other configs ...
  rehypePlugins: [ latex ],
})

Remember to add the style in your layout component, or directly in the _app.tsx. Something similar to this:

    <>
      <Head> // 👈 this is next/head
        <link
          rel="stylesheet"
          href="https://cdn.jsdelivr.net/npm/[email protected]/dist/katex.min.css"
          integrity="sha384-zTROYFVGOfTw7JV7KUu8udsvW2fx4lWOsCEDqhBreBwlHI4ioVRtmIvEThzJHGET"
          crossOrigin="anonymous"
        />
      </Head>
      ...
    </>

Let me know if it works on your project, I just tried it in the monorepo, not a standalone repo, there might be some issues.
