astro-rehype-relative-markdown-links v0.14.1

astro-rehype-relative-markdown-links

This is a rehype plugin built for Astro that aims to transform relative links in MD and MDX files into their final output paths.

🚨 This is experimental and build exclusively for Astro. I have made a couple assumptions. They are:

1. You are rendering a static site (i.e. not using SSR)
2. You have a content collection residing at src/content/<content_collection>
3. You have a page that renders the above content collection at src/pages/<content_collection>/[...slug].astro

Example Functionality

If you have a markdown files at src/content/blog/post.md with the content of:

[relative link](./other-markdown.md)

The resulting HTML should be:

<a href="/blog/other-markdown">relative link</a>

It supports links with Query Strings and Hashes (e.g. [relative link](./other-markdown.md?query=test#hash)).

OS Support

Tested with Node.js v18 and Astro 2.x.

• MacOS (Ventura)
• Windows (Windows 11)
• Linux (Debian 11)

Notes

• I'm currently using this in my blog. Use it as an example if it's easier!
• This rehype plugin was called rehype-astro-relative-markdown-links in the past. I've changed this due to rehype's naming guidelines.
