mdorigin is a markdown-first publishing engine.

It treats markdown as the only source of truth, serves raw .md directly for agents, renders HTML for humans from the same directory tree, and can expose the same content to both browsers and tools through stable routes.

mdorigin is not meant to become a template system.

Its core is:

• routing rules
• markdown tree normalization
• document, index, asset, search, and site semantics
• stable page models derived from the same content tree

That means mdorigin should own content semantics, while page rendering remains extensible. In practice, this is the direction for advanced customization: users should be able to replace page-level rendering with code, without replacing the routing and content kernel itself.

• markdown stays directly accessible at .md routes
• extensionless routes render human-friendly HTML from the same files
• README.md, index.md, and SKILL.md all fit into one routing model
• the same core works in local preview and Cloudflare Workers
• optional search is powered by indexbind

npm install -g mdorigin

Then run it directly:

mdorigin dev --root docs/site

If you prefer a project-local install instead, use npm install --save-dev mdorigin and run it with npx --no-install mdorigin ....

mdorigin dev --root docs/site
mdorigin build index --root docs/site
mdorigin build cloudflare --root docs/site

That is enough to preview a site locally, keep directory indexes up to date, and generate a Cloudflare Worker bundle.

mdorigin now supports a code config alongside mdorigin.config.json.

Use mdorigin.config.ts when you want to customize rendering or indexing with code instead of asking for a template system:

export default {
  siteTitle: "My Site",
  plugins: [
    {
      name: "custom-footer",
      renderFooter() {
        return '<footer class="custom-footer">Built with mdorigin</footer>';
      },
    },
  ],
};

Current stable hooks are:

• transformIndex(entries, context)
• renderHeader(context)
• renderFooter(context)
• renderPage(page, context, next)
• transformHtml(html, context)

All render hooks that receive a RenderHookContext (renderHeader, renderFooter, renderPage, and transformHtml) can read the normalized markdown frontmatter for the current document via context.page.meta, including custom fields such as syndication.

The intended boundary is:

• mdorigin owns routing and normalized content semantics
• plugins may replace page rendering
• plugins do not replace the request kernel itself

mdorigin can build a local retrieval bundle through the optional indexbind package. For the retrieval engine itself, see the indexbind docs: https://indexbind.jolestar.workers.dev.

npm install indexbind
mdorigin build search --root docs/site
mdorigin search --index dist/search "cloudflare deploy"

build search now defaults to the higher-quality model2vec backend. If you need a smaller or faster fallback, you can opt back into hashing:

mdorigin build search --root docs/site --embedding-backend hashing

To expose the same search bundle from the site runtime:

mdorigin dev --root docs/site --search dist/search
mdorigin build cloudflare --root docs/site --search dist/search

For media-heavy sites that would exceed Worker bundle limits, build in external binary mode instead:

mdorigin build cloudflare --root docs/site --binary-mode external
mdorigin sync cloudflare-r2 --dir dist/cloudflare --bucket <bucket-name>
mdorigin init cloudflare --dir . --r2-bucket <bucket-name>

In this mode, markdown and other text stay embedded in the Worker bundle, smaller binaries are staged for Workers Static Assets, and oversized binaries are staged for R2.

mdorigin ignores dotfiles and dot-directories during content traversal. .gitignore is not used to decide publish visibility.
