Solid-jsx NPM | npm.io

solid-jsx

What?

This module is ESM only, due to mdx and xdm being ESM only.

Adding

"type": "module"

in package.json is one option.

Installation

pnpm install --save-dev solid-jsx

Usage

This library can be used alongside version 2 of @mdx-js, or xdm by setting the jsxImportSource property to 'solid-jsx'.

You can use their official integration with various bundlers, and frameworks, below is an @mdx-js configuration sample for Vite, which supports rollup plugins.

import { defineConfig } from 'vite';
import solid from 'vite-plugin-solid';
import mdx from '@mdx-js/rollup';
import remarkGfm from 'remark-gfm';

export default defineConfig({
  plugins: [mdx({ jsxImportSource: 'solid-jsx', remarkPlugins: [remarkGfm] }), solid()],
  build: {
    target: 'esnext',
  },
});

Draw math with xdm and mathjax

import solid from 'vite-plugin-solid';
import xdm from 'xdm/rollup.js';
import remarkMath from 'remark-math';
import uno from 'unocss/vite';
import remarkMath from 'remark-math';
import rehypeMathJaxSVG from 'rehype-mathjax/svg.js';

export default defineConfig({
  plugins: [
    xdm({
      jsxImportSource: 'solid-jsx',
      remarkPlugins: [remarkMath],
      rehypePlugins: [rehypeMathJaxSVG],
    }),
    solid(),
    uno(),
  ],
});

More information -> Integrations.

All markdown tags and custom components replacement are supported.

However, since the code goes through the @mdx-js/xdm compiler and not through the solid-js compiler, inline components will not be reactive.

export const Counter = () => {
  const [count, setCount] = createSignal(0);
  return (
    <>
      <button onClick={() => setCount(count() + 1)}>Increment</button>
      <p>{count}</p>
    </>
  );
};
<Counter />;

This limitation is minor, since writing components inline is just one option, and by far the worst one of them all, with limited syntax and language support.

You can always import directly TypeScript/JavaScript components inside .mdx

import Counter from './Counter';

<Counter />

or pass the component to markdown directly

Hello <Counter />

import Message from './message.mdx';

<Message components={{ Counter }} />;

To have dynamic tags, use solid-js Dynamic component.

const options: Record<string, Component> = {
  red: RedThing,
  green: GreenThing,
  blue: BlueThing,
};
<Message
  components={{
    h2: 'h6',
    h1: () => <div>Test</div>,
    Planet: () => <Dynamic component={options[selected()]} />,
  }}
/>;

When nesting MDX files, importing components at the top or repeating the same set of those as parameters can become cumbersome.
You can use MDXProvider to avoid this:

import { MDXProvider } from 'solid-jsx';

render(() => (
  <MDXProvider components={{ Tweet }}>
    <App />
  <MDXProvider>
  )
);

The package also provides Typescript support, the types can be referenced as "solid-jsx/types". In tsconfig.json:

{
  "compilerOptions": {
    "types": ["vite/client", "solid-jsx/types"]
  }
}
