Feature: Publish mdxjs-rs to npm with native bindings

[jp-knj]

Summary

I'd like to propose adding npm package distribution for mdxjs-rs to make it easier to integrate into Node.js projects like Astro, Next.js, and other build tools.

Background

Currently, mdxjs-rs is an excellent Rust implementation of MDX, but it requires custom bindings to use from Node.js. This creates barriers for adoption:

• Each project needs to create their own bindings
• Maintenance burden is duplicated across projects
• Performance benefits are not easily accessible

Use Case

At Astro, we're working on integrating mdxjs-rs to provide 5-15x faster MDX compilation for large sites (PR #14080). However, we need to either:

1. Create custom bindings (maintenance burden)
2. Use third-party packages like @rspress/mdx-rs (which appears unmaintained)

Proposal

Would you consider:

1. Publishing official npm package with pre-built binaries for major platforms

   • Similar to how @swc/core or @parcel/watcher work
   • Using N-API for stability across Node versions

2. Minimal API surface to start:

   import { compile, compileSync } from 'mdxjs-rs';
   
   const result = await compile(mdxContent, {
     filepath: 'example.mdx',
     development: true
   });

There's some related discussion at wooorm/markdown-rs#6

It’s open, yeah.
I’d also think a separate isomorphic project that uses either JS or RS based on config. Based on plugins. Maybe a good idea.

plugin-based approach... sounds good.
