mdx-formatter Documentation Site

Documentation site built with zudo-doc 5.2.1 — a zfb-based documentation framework with MDX, Tailwind CSS v4, and Preact islands. This project is intentionally minimal: one config file (zfb.config.ts) plus markdown content — layout, chrome, and islands all ship from @takazudo/zudo-doc in node_modules. Node.js >= 22 is required.

Tech Stack

  • zfb — documentation build framework

  • MDX — content format, authored under src/content/

  • Tailwind CSS v4 — compiled by zfb's embedded Tailwind engine (no @tailwindcss/vite plugin, no tailwindcss dependency); src/styles/global.css imports tailwindcss/preflight + tailwindcss/utilities and zfb's internal resolver serves both

  • Preact — for interactive islands only (with compat mode for React API)

  • zfb semantic highlighting — native build-time fenced-code rendering plus lazy @takazudo/zfb-md-wasm for HtmlPreview; both emit hi-* classes resolved through --zd-syntax-* design tokens

  • @takazudo/zudo-doc — the package that owns everything: layout, chrome, islands, default @theme design tokens, and (via packageOwnedRoutes, on by default) the doc routes themselves

Commands

  • pnpm dev — runs the zfb dev server (port 4321) and the doc-history API server (port 4322) concurrently via run-p (pnpm dev:zfb / pnpm dev:history individually)

  • pnpm dev:network — same, but zfb binds --host 0.0.0.0 for LAN access (pnpm dev:zfb:network individually); the doc-history server stays loopback-only and LAN clients reach it through zfb's /doc-history/* dev proxy

  • Trusted networks only: this also serves your git doc-history — including UNPUBLISHED local commits — to anyone on the LAN via the /doc-history/* proxy

  • run-p swallows trailing args, so other zfb flags don't forward through pnpm dev — pass them directly instead: pnpm run dev:zfb -- <flags>

  • pnpm build — runs zfb build for a static HTML export to dist/

  • pnpm check — runs zfb check for type and content checking

  • pnpm preview — runs zfb preview to serve the built dist/

The formatter playground loads project-owned WASM files from public/wasm/. From the repository root, run pnpm build:wasm:doc before using the playground locally. The docs CI action performs this step before zfb build.

Key Directories

zfb.config.ts             # THE one config file — zudoDoc({ ...only fields you chose })
pages/
├── index.tsx             # 1-line re-export of the package home route
└── docs/[[...slug]].tsx  # self-contained doc-route stub (required for `pnpm dev`)
  [locale]/docs/[[...slug]].tsx  # same, for non-default locales
src/
├── chrome-bindings.tsx   # optional typed primary chrome / named header / MDX bindings
├── content/

└── styles/
    └── global.css        # @import chain + a token-override slot — that's it

Everything else — layout, header, sidebar, footer, doc chrome, islands, and the default design tokens — lives in node_modules/@takazudo/zudo-doc. For supported markup replacement, create src/chrome-bindings.tsx with defineChromeBindings, set chromeBindingsModule, and use the primary Header / Footer / Sidebar / Toc / Breadcrumb / DocPager slots or the named headerRightComponents registry. The generated default, locale, and doc-history route shapes already consume the same binding object; do not fork a route stub for presentational customization. npx zudo-doc eject <component> only copies source: heed its primary, nested-chrome, or content-layer remediation before expecting the copy to render. Settings you didn't set explicitly in zfb.config.ts use the package's documented defaults — hover zudoDoc's ZudoDocConfig argument in your editor to see every field and its @default.

Content Conventions

Frontmatter

  • Required: title (string)

  • Optional: description, sidebar_position (number), category

  • Sidebar order is driven by sidebar_position

Admonitions

Available in all MDX files without imports, via directive syntax: :::note, :::tip, :::info, :::warning, :::danger, :::caution, :::details. Each accepts an optional bracketed title: :::note[Custom Title].

Docusaurus-style {title="..."} is NOT supported. MDX parses the braces as a JS expression, so it either fails the build with ReferenceError: title is not defined or is silently ignored. Always use the bracketed form.

Headings

Do NOT use h1 (#) in doc content — the page title from frontmatter is rendered as h1. Start content headings from h2 (##).

Built-in MDX components

@takazudo/zudo-doc ships a few globally-available MDX components — usable in any .mdx file with no import. The Japanese overview index uses one:

  • <CategoryNav category="..." /> — a card-grid list of the pages in a docs category (used by src/content/docs-ja/overview/index.mdx).

  • <CategoryTreeNav category="..." /> — the same listing as a compact nested tree, better for deeper hierarchies.

  • <SiteTreeNavDemo /> — a full-site documentation tree (the MDX-available wrapper of the SiteTreeNav island).

Admonitions (above), tabbed content (<Tabs> / <TabItem>, <CodeGroup>), and block math (<MathBlock>) work the same way — no import. Full reference: https://zudo-doc.takazudomodular.com/docs/components/

i18n

  • English (default): /docs/... — content in src/content/docs/

  • Japanese: /ja/docs/... — content in src/content/docs-ja/

  • Japanese docs should mirror the English directory structure

  • Both pages/docs/[[...slug]].tsx and pages/[locale]/docs/[[...slug]].tsx are self-contained doc-route stubs shipped by the generator — required so pnpm dev doesn't 404 on doc pages (a zfb dev-mode limitation on package-injected dynamic routes). Don't delete them.
