@modern-js/mdx-rs-binding

This is a Node.js binding for MDX compliation of Modern.js Doc which is a modern documentation tool based on Rspack.

It can be 10x+ faster than compiler in pure JavaScript version.The benchmark result of @modern-js/mdx-rs-binding vs @mdx-js/mdx is as follows:

| Tool | Time Spend |
| ------------------------- | ---------- |
| @modern-js/mdx-rs-binding | 163 ms |
| @mdx-js/mdx | 3288 ms |

We forked mdxjs-rs, the Rust version of mdx compiler and customize it for Modern.js Doc, adding the following features:

| Crate | Description |
| ----------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| mdx_rs_binding | 🔥 Add Node.js binding so that we can use it in Node.js. |
| mdx_plugin_container | Implement container grammar like :::tip in @modern-js/remark-container. |
| mdx_plugin_toc | Generate table of contents. |
| mdx_plugin_frontmatter | Parse frontmatter and export it in the esm module. |
| mdx_plugin_external_link | Add target="_blank" and rel="noopener noreferrer" to external link. |
| mdx_plugin_header_anchor | Add anchor for every header. |
| mdx_plugin_normalize_link | Normalize link to complete url base on current filepath. |
| mdx_plugin_html | Serialize hast to html string |
| slugger | Generate slug for header, port from github-slugger. |

Install

``bash


npm

npm install @modern-js/mdx-rs-binding

yarn

yarn add @modern-js/mdx-rs-binding

pnpm

pnpm install @modern-js/mdx-rs-binding
`

Usage

`js
import { compile } from "@modern-js/mdx-rs-binding";

async function main() {
const value =
# Hello World

This is a demo of @modern-js/mdx-rs-binding
;

const result = await compile({
// The mdx content
value,
// File path of the mdx file, the compiler will determine the different syntax(md/mdx) based on the file extension
filepath: "xxx.mdx",
// Whether to enable development mode, default is false
development: true,
// Current working directory, can be empty string
root: "",
});

console.log(result);
}
`

Of course, you can also the compileSync function to compile mdx synchronously, which is not recommended because it will block the event loop and slow down the compile process.

`js
import { compileSync } from "@modern-js/mdx-rs-binding";

function main() {
const value =
# Hello World

This is a demo of @modern-js/mdx-rs-binding
;

const result = compileSync({
// The mdx content
value,
// File path of the mdx file, can be empty string
filepath: "",
// Whether to enable development mode, default is false
development: true,
// Current working directory, can be empty string
root: "",
});

console.log(result);
}
``
