Is any way to convert .mdx to .html without nextjs?

[zfben]

I found most of mdx packages are convert .mdx to js code, how should I convert it to static HTML for SEO? (And if I don't use Next.js)

Thank you.

There are many ways. Which way works for you, depends on what you do use.

I see the Site generators section in the document, but they use 3rd packages.
Can I generate static HTML without these 3rd tools?

Please properly read the “Quick start” section. In particular, see the list following “You can also use MDX if you’re not using a bundler:” Then, see the following subsection too: “JSX”.

To summarize: you can import MDX in Node or use evaluate from mdx-js/mdx. You have to choose a JSX runtime though. React, Preact, Svelte, Vue, etcetera.

My problem is mdx-js/mdx generate javascript code, not html code. I want to generate HTML code for better SEO.

No it doesn’t. importing in Node and evaluate do not return code. They compile and evaluate code. they return components. You can render those components to get HTML.

@wooorm Thanks a lot. Finally, I know how to generate HTML.

import remarkGfm from 'remark-gfm'
import rehypeHighlight from 'rehype-highlight'
import { renderToString } from 'react-dom/server'
import * as runtime from 'react/jsx-runtime.js'
import { evaluateSync } from '@mdx-js/mdx'
import { createElement } from 'react'

export function generate (body: string) {
  const mdx = evaluateSync(body, {
    ...runtime as any,
    remarkPlugins: [remarkGfm],
    rehypePlugins: [rehypeHighlight]
  }).default

  return renderToString(createElement(mdx))
}
