cudoc-export writes an HTML site, single HTML pages, review pages, PDF and Word from one collected document set and one set of design tokens.

It is an optional output beside the site you have, for documents written with cudoc's Markdown extensions and document embedding. Keep Next.js, Docusaurus, Nextra, VitePress or Eleventy as the primary documentation host and run cudoc-export beside it on the same collected documents and prepared embeds: no second document set, and no change of host. It also runs on its own, with no application scaffold, and the output deploys to a static server or opens from disk.

Your first site, from an empty directory

Two commands and two documents give you a complete site. You need Node.js 22 or later and npm: no site, no framework, no config file.

npm install @cudoment/cudoc cudoc-export

Write two documents. docs/reference.md holds the facts:

# Reference

## Limits (#limits)

The limit is 100 requests per minute.

## Authentication (#authentication)

Send an access token with each request.

docs/index.md reuses them instead of repeating them:

# Product guide

> [!NOTE] About this guide
> The table below is generated from the reference document.

```cudoc-embed
sources: [reference.md]
select: { depth: 2 }
render: { type: table }
```

Build:

npx cudoc-export build docs --out-dir site

site/index.html is a styled site with navigation, a heading table of contents and a summary table whose rows link into reference.html. The builder collected the documents, resolved the embed and wrote HTML, styles and local assets, with callouts, scrollable tables and highlighted code. Edit a document, run the command again, and every page that references it updates with it.

Share the whole site/ directory or deploy it to any static host: nothing in the output needs a server, a bundler or a CDN, so it opens from file:// as readily as from a URL. To send one page as a single file instead, write it with mode: "standalone". → Three kinds of HTML

Complete examples

Finished exports committed with the repository show every option below in its output. The documents are a six-document handbook for a fictional weather API under examples/export/showcase/, in English with Korean translations of two of them, and npm run showcase inside examples/export builds them four ways:

review-samples/ holds the notes a reader returned on the page to review and the report cudoc-export annotations made from them. The documentation site publishes the first three under showcase/, samples/standalone/ and samples/annotate/, so they open in a browser without a checkout.

Open northlight-handbook.pdf for the bound volume of twenty-eight pages, northlight-handbook.docx for the same volume in Word, and getting-started.pdf or getting-started.docx for one document on its own.

What the samples are made of:

• The documents use what an author writes in Markdown: explicit anchors and badges, callouts including a registered success type, and lists inside table cells with a layout rule that splits the long column. They also use an embed that reads each endpoint's method and path out of the reference into a summary table on the overview page, and an embedded section reworded with replace. The rest are a footnote, an image, request and response samples (in curl, Node.js, Python, HTTP and SQL), a seven-column table and a cudoc-pagebreak fence before an appendix.
• The site configuration turns on all three formats at both granularities, a cover image, a numbered contents page, and a running header and footer with a fixed date. It also turns on printed link addresses, landscape pages for tables of six columns or more, minimum widths for the description and date columns, the theme menu, and an accent colour that reaches all three outputs through tokens.
• The other three configurations import it and change only what their mode needs.

tests/scripts/export-showcase.mjs rebuilds all four and fails when a committed text output differs from what the current packages produce, so no sample lags behind a release.

Three kinds of HTML

mode (or --mode) decides what the HTML output is:

A single page, which standalone writes and annotate writes by default, is one document without the site around it: no navigation, home link or language menu. PDF and Word are written in every mode when formats asks for them.

documents (or repeated --document) picks the documents a single-page run writes, by id or file name, from those the site publishes; without it every published document gets its page. A site writes every page it publishes, so documents there is an error:

npx cudoc-export build docs --out-dir out --mode standalone --document guide.md

What a single page carries

A single page shows the same thing from a download folder, a chat attachment or another machine, because what it shows is inside it:

A run prints what each page needs from outside on standard error, and returns the same list as dependencies:

cudoc-export: guide: needs a file beside it: spec.pdf
cudoc-export: guide: needs a page beside it: reference.md
cudoc-export: guide: needs a remote resource: https://example.com/diagram.png

strict: true (or --strict) turns any of them into an error, for a page that must stand entirely on its own. A resource larger than standalone.maxAssetBytes once written inline (5 MiB by default), or a page larger than standalone.maxPageBytes (20 MiB), stops the build, so a page stays quick to open and small enough to save again with notes in it.

Export alongside an existing site

Export reads the library your host's collector wrote, so the site and the export share one collection. Run the collector from your host guide first: it captures the actual host compiler's output and prepares the embeds. Then install cudoc-export in that project and create site.config.mjs:

export default {
  sourceRoot: "docs", // "content" in the Nextra guide
  library: ".cudoc/documents",
  outDir: "shared-html",
  title: "Product documentation",
  links: "host",
  hostUrl: "https://docs.example.com/project/",
  assetDirs: ["public"], // Docusaurus usually uses "static"
}

npm run collect
npx cudoc-export build --config site.config.mjs

The host build and the export both read the collection and run in either order after it. library reuses the stored AST, native heading IDs, routes and prepared embeds, including replacements compiled by asynchronous hosts, and reads the library without rebuilding or modifying it. Give the main site and the export separate output directories.

Keep syntax, component mappings and compiler configuration in the collector, and do not repeat them in this configuration when library is set. Recollect and prepare after editing documents, routes or compiler settings: export reads the collected snapshot, not unsaved or newly edited source. A document without embeds needs no prepared-embed file; a document with embeds requires it.

For a single command after collection:

npx cudoc-export build docs --library .cudoc/documents --out-dir shared-html \
  --links host --host-url https://docs.example.com/project/ --asset-dir public

PDF and Word

The same collected documents export as PDF and as Word from one call:

import { buildExport } from "cudoc-export"

await buildExport({
  sourceRoot: "docs",
  outDir: "out",
  title: "Product documentation",
  formats: ["html", "pdf", "docx"],
  granularity: "both",
})

or from the command line:

npx cudoc-export build docs --out-dir out \
  --format html --format pdf --format docx --granularity both

Every run writes the HTML output, so formats names what to add to it: pdf, docx or both. The default, ["html"], writes what buildSite writes, and "html" beside the others changes nothing.

granularity decides what a run produces: documents writes one file per document, volume one bound file holding every document in navigation order, and both writes each. Both exist because a cross-document link resolves only inside a bound file; in per-document output it points at the sibling file instead.

Every format reads one set of design tokens, so a PDF is the site's stylesheet printed rather than a second design, and Word takes the same palette, type scale and spacing translated into Word styles. A callout is the same colour in all three: WARNING in the warning colour, CAUTION and a registered danger or error type in the danger colour, and every other type in the accent. The tokens keys are listed in the adapter reference.

The bound volume

The bound file opens with a cover page carrying the title, then a contents page listing every document with the page it starts on, then the documents, each starting on a new page. The default language's documents come in navigation order, then the hidden ones. volume.order moves the documents it names to the front, in its order. volume names the file and shapes that front matter:

await buildExport({
  sourceRoot: "docs",
  outDir: "out",
  formats: ["pdf", "docx"],
  granularity: "volume",
  volume: {
    fileName: "handbook", // handbook.pdf, handbook.docx, handbook.print.html
    cover: { image: "design/cover.png" }, // false for no cover page
    contents: { title: "Contents", pageNumbers: true }, // false for none
    order: ["overview.md"], // first, then the rest in navigation order
  },
})

cover.image is a local PNG, JPEG, GIF or BMP file, printed behind the title and filling the page's content box; the title sits on a paper-coloured band so it reads over any picture. SVG is refused, because Word cannot carry one.

The contents page numbers are exact in the PDF, measured by printing each document. In Word they are a live table-of-contents field that Word fills when it updates fields on opening, so other viewers show the titles without numbers until then. contents.pageNumbers: false skips the measuring print and the number column in both.

The page

Paper defaults to A4 portrait with 20mm margins, 22mm at the bottom, and every paginated format reads the same page options:

await buildExport({
  sourceRoot: "docs",
  outDir: "out",
  formats: ["pdf", "docx"],
  page: {
    paper: "Letter",
    margin: { top: "25mm" },
    header: "{title}",
    footer: { left: "{date}", right: "{page} / {pages}" },
    date: "2026-09-16",
    breakBefore: 1,
    linkUrls: true,
  },
})

Lengths take mm, cm, in, pt or px, and a bare number means millimetres; each is converted to millimetres once, so the PDF and Word lay out the same page.

header and footer are the running lines the PDF prints in the margins and the Word file carries in its header and footer. They accept {page}, {pages}, {title} and {date}, either as one centred string or as left, center and right slots, and false prints none. {date} prints only a date you supply as page.date: cudoc never reads the clock, so the same input always produces the same output.

The running lines have two limits. A margin narrower than 15mm cannot hold one and is an error rather than a clipped header. A header naming the current section is not possible, since Chrome implements no CSS mechanism for it, so a per-document file's header is that document's title and a bound volume's is the volume title.

The other page options decide page breaks, printed addresses and wide tables:

• breakBefore: 1 starts a new page before every first-level heading, 2 before second-level headings too, up to 3; a document already starts on a new page in the volume.
• linkUrls: true prints an external link's address after its text, for readers holding paper.
• authoredBreaks: false makes the paginated outputs ignore ```cudoc-pagebreak fences, for a run where the author's breaks were placed for another paper size.
• wideTables: { minColumns: 6 } puts every table with at least that many columns on a landscape page of its own, in the PDF and in Word alike; without it a wide table shrinks to the portrait column. A table that is a document's very first block, or one inside another table's cell, stays on the portrait page.
• A cudoc-pagebreak fence directly before or after a table that gets its own landscape page is dropped, since that page already starts and ends there. A fence that opens a document is dropped too, since the document starts on a page already. A break anywhere else stays.

How the PDF is made

A site always writes print-ready HTML, <document>.print.html and <volume>.print.html beside its pages plus cudoc-print.css, whether or not a browser is installed, and single pages write it when a PDF is asked for. You can open and print those yourself. When you ask for pdf, cudoc prints them with a headless Chromium, in one browser session.

That browser is installed with the package: only the 187MB headless shell rather than a full browser suite. CUDOC_SKIP_BROWSER_DOWNLOAD=1 keeps an install from fetching it (any value other than an empty one, 0 or false, spelled exactly so, skips it, as PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD does), and npx cudoc-export install-browser installs it later.

npm 12 and later run a dependency's install script only once the project approves it, so there run npm install-scripts approve cudoc-export and install again, or use npx cudoc-export install-browser, which works either way. A PDF asked for without a browser is an error naming that command; the run writes nothing and the previous output stays. A run without pdf writes the print-ready HTML, which you can print yourself. To use a browser you already have, pass its path as pdf.executablePath.

Links in the paginated outputs

The link policy from Choose hyperlink behavior applies to the print HTML, the PDF and the Word file exactly as to the site, and each spells the same target its own way:

A published document the bound volume does not hold, a translation or a home the navigation leaves out, is linked at its site page, or its deployed page under host. A per-document file drops the fragment because neither a PDF viewer nor Word addresses a heading inside another file reliably. A fragment stays inside the file under every policy, including host: on paper the target is a later page, not a website.

With host and linkUrls: true, a link from one document of the volume to another still prints the deployed address after its text in the PDF, as that document's own PDF does. Each document therefore fills the same pages in the volume as alone, and the contents numbers hold.

What Word carries, and what it does not

The Word document is styled through named styles alone. Headings, body text, quotes, code, tables, captions, footnotes, the running header and footer, the cover, the contents and each callout type has a style of its own. Nothing in the body carries a colour, font, size, shading or border directly. A reader can therefore restyle the whole document from Word's styles pane, and a document handed to someone can be reshaped to their own template.

The one exception is the table cell, where OOXML keeps rules and tints. A table follows the site, with a rule under the header, a soft rule between rows, every other body row tinted and no vertical grid. Its grid spans the content width, split evenly except for a column whose header asks for a minimum width. A viewer that lays tables out from the grid, such as Pages or Quick Look, therefore shows a table as wide as Word does.

What each part of a document becomes in Word, and what is dropped:

Every drop is reported in the result's diagnostics and on the CLI's standard error, naming the document.

Four things of the site's design do not survive, and are dropped rather than approximated:

• Rounded corners: OOXML borders are square.
• The reading-measure bound: expressed once, as page margins.
• The dark theme: a .docx carries one theme.
• The CSS font stacks: Word takes one family per script from tokens.word, Calibri, Consolas and Malgun Gothic by default, faces Office installs on Windows and macOS alike. A document therefore opens in the face it was set in rather than in Word's substitute for a web font.

tokens.word also holds the template's spacing. Each of these is one key: the space after a paragraph, before a heading, around a block and after a list item; the list and quote indents; and the padding of boxes and cells. A document that reads too loose or too tight in Word is therefore tuned without touching the site. The keys, their defaults and where each is applied are listed under Word template.

The css option reaches the HTML pages only: the print HTML, and so the PDF, is styled from tokens, and Word reads no CSS. Use tokens for anything that should hold across formats.

Three choices belong to the Word writer alone and sit under docx:

import { Paragraph, TextRun } from "docx"

await buildExport({
  sourceRoot: "docs",
  outDir: "out",
  formats: ["docx"],
  docx: {
    rawHtml: "text", // keep raw HTML as a code block instead of dropping it
    calloutStyle: "table", // box each callout in a single shaded cell
    components: {
      ProductMark: () => [new TextRun({ text: "Product", bold: true })],
      Steps: (node) => [
        new Paragraph({ text: `${node.children.length} steps` }),
      ],
    },
  },
})

rawHtml: "text" writes the HTML source as a code block, and reports each occurrence as html-as-text rather than dropped-html. calloutStyle: "table" is closer to the site's box, at the price of the tint and the rule living in the cell's own properties rather than in a named style.

A component renderer is called with the node and returns docx objects: paragraphs and tables where the component stands as a block, runs where it stands inside text; a paragraph returned inline is an error. It is the Word counterpart of renderOptions.components in Assets and custom components.

Choose hyperlink behavior

links (or --links) decides what every hyperlink in the output becomes; the policy is one of three:

The policy applies to authored links, raw HTML, embedded sections and tables, and the generated navigation and footnotes. The contents beside a page link within the page under relative and host, and none removes them like any link. Local images and styles remain available under every policy: none removes clickable anchors, not rendering resources such as the stylesheet's <link> element, and copies no file that only a removed hyperlink referenced.

A target that is not in the output is handled per policy; a stopped build names the resource and the document that carries it:

In host mode, set hostUrl to the full deployment URL including its base path. With https://docs.example.com/project/ and a collected route /docs/start, both start.md#setup and /docs/start#setup become https://docs.example.com/project/docs/start#setup, and an already-prefixed route does not get a second /project/. Query strings and fragments are preserved, a fragment-only link targets the current document on the deployed site, and other local paths resolve against the deployment and the current document's route.

A link to a file that is not collected, such as a source file, opens it in the repository when sourceLinks names one, under relative and host alike. → Files that are not documents

Set custom slugs and routes in the collector to match the primary site's URLs: HTML export does not infer routing from host configuration. links controls exported hyperlinks and is separate from syntax.link, which controls syntax normalization during collection.

Configure the site

Create site.config.mjs:

export default {
  sourceRoot: "docs",
  outDir: "site",
  title: "Product documentation",
  navigation: "docs/nav.yml",
  locales: { en: "English", ko: "한국어" },
  header: {
    links: [{ title: "GitHub", url: "https://github.com/owner/repo" }],
  },
  toc: { depth: 3 },
  syntax: { headingAnchor: "cudoc", callout: "cudoc" },
  links: "relative",
  // css: ["theme/brand.css"],
}

npx cudoc-export build --config site.config.mjs

A configuration may also be JSON or YAML (.json, .yml, .yaml); only callback options, renderOptions, docx.components and extractors, need an ES module. Paths in it are read from the directory the command runs in, and an option cudoc does not know is an error, so a misspelt key never passes silently. This configuration collects Markdown directly; to reuse an existing host library, add library and remove the collection options such as syntax.

The navigation

navigation is the list on the left, and also what the site publishes. A document the navigation does not list and hidden does not name is written by no format, so a draft stays out of the site, the PDF and the Word file alike. The one exception is the home page, which is published whether or not the navigation lists it. Without navigation, every document is listed, folder by folder, index.md first. The result's omitted names each document left out and why.

Write the navigation in a YAML file and give its path, or write the same entries in the configuration:

# docs/nav.yml
items:
  - index.md # a file: that document alone
  - guides # a folder: every document in it, its subfolders as groups
  - folder: reference # a folder with settings
    title: { en: Reference, ko: 레퍼런스 }
    page: README.md # the document the folder's title opens
    exclude: [draft-*.md] # left out of this folder
    order: [overview, ...] # these first, then the rest by title
    depth: 1 # levels drawn as groups; deeper documents are listed flat
    collapsed: true # the group starts closed
  - title: Tools # a group of entries, in the order written
    items: [cli.md, api.md]
  - title: Status # a link out
    url: https://status.example.com/
hidden: # published, but not listed
  - legal/privacy.md

• A document is written with its extension, guide.md; a name without one is a folder, and . is the whole collection.
• A document is listed once. An entry that names it wins over a folder that would bring it in. Naming it twice, or naming a private document, is an error that gives the file and line.
• In a folder, setup.md stands for the folder setup/ beside it, and otherwise setup/index.md does, as in a tree embed; a folder nothing stands for is a group under its own name. A README.md stands for its folder only when page names it.
• A folder's entries sort by title. order lists names to put first, and ... stands for every name not listed, so [..., changelog] puts one name last.
• An order or exclude name that matches nothing, and a document without a translation, are reported in the result's diagnostics (unmatched-navigation-order, unmatched-navigation-exclude, missing-translation) and on standard error.
• A link to a document the site does not publish is an error under relative links, since the page it points at would not exist; the message names the document and the way out.

The showcase navigation and the documentation site's navigation are both written this way.

Languages

locales names the languages the documents are written in, the default first:

locales: { en: "English", ko: "한국어" }

The default language's files carry no suffix, and every other language's end in .<code>.md, so guide.ko.md is the Korean guide.md. Write the navigation with the default language's files: each language draws its own list from the translations and leaves out a document that has none.

Every page links to the same document in the other languages from a drop-down menu in the header, or to that language's home when there is no translation; the menu needs no script, and a click elsewhere closes it. A page's <html lang> is its language's code, or the document's front matter lang when that makes the code more specific, such as ko-KR; front matter naming another language is an error, since the file name already decides it.

A language can take another suffix and its own words for the page's controls: { ja: { label: "日本語", suffix: ".jp", ui: { documents: "ドキュメント" } } }. cudoc has the words for English and Korean, and uses the English ones for any word another language does not set; the keys are listed in the adapter reference. The bound volume holds the default language; with granularity documents or both, a translation is written as its own PDF and Word file.

Home, header and contents

The site opens on index.md, or on the document home names, such as home: "README.md", which is then written as index.html and its translations as index.<code>.html. A home must exist in every language, and an index.md beside another home is refused, since both would be written to index.html. Without either, a landing page listing the navigation is generated.

header.links adds links beside the site title, each with a title that may name one text per language like a navigation title. The contents on the right list headings down to the level toc.depth names, from 2 to 6 and 6 by default; toc: false leaves them out everywhere, and front matter toc: false on one page. A page with no heading to list has none, and a home document lists its contents like every other page.

Look

The built-in stylesheet follows the viewer's light or dark system setting, needs no script to do so, and keeps every colour in a custom property that both themes define.

themeSwitch: true (or --theme-switch) adds a theme menu to the header with Light and Dark, a drop-down drawn like the language menu rather than the browser's own control. Until the reader chooses, the page follows the system setting and the menu shows which one it is, and the browser remembers a choice. It is the one small script the site loads besides the review-note runtime, and the default output stays without it.

css names one stylesheet or a list, loaded after the built-in one. A site links each as its own file under cudoc-css/, and copies an image or font it loads to cudoc-css/files/ under a name taken from the file's content; a single page carries its text and those files inline. To restyle the site, redefine the custom properties rather than rewriting the rules; the full token list is in the adapter reference:

/* theme/brand.css, loaded after the built-in stylesheet */
:root {
  --accent: #7c4dff;
  --accent-soft: #ece7fb;
  --measure: 78ch;
  --font-sans: "Inter", system-ui, sans-serif;
}
/* Not on a page the reader set to Light with themeSwitch. */
@media (prefers-color-scheme: dark) {
  :root:not([data-theme="light"]) {
    --accent: #b39dff;
    --accent-soft: #2a2244;
  }
}
/* With themeSwitch, a reader may choose Dark on a light system: repeat the
   dark values here. */
:root[data-theme="dark"] {
  --accent: #b39dff;
  --accent-soft: #2a2244;
}

Files that are not documents

A guide often links to something that is not a page: a source file, an example's configuration, a folder of samples. Two options say where those live:

export default {
  roots: [{ dir: "docs", base: "docs" }],
  outDir: "site",
  sourceLinks: {
    root: ".",
    url: "https://github.com/owner/repo/blob/v1.2.0/",
  },
  mounts: [{ from: "examples/output", to: "examples" }],
}

sourceLinks sends a link to a file that exists under root but is not collected to url followed by its path, so [the CLI](../src/cli.ts#L10) opens on GitHub at that commit. The library's paths are read from root, which is why the documents above are collected under the base docs. It applies under relative and host alike, and a link this way to a private document's file is an error.

mounts copies each folder into the output as it is and points every link into from at its copy under to. A mount is part of a site with relative links: single pages and host or none links refuse one, as does a mount that overlaps a collection root, an asset directory, the library or another mount.

The documentation site links its source files and publishes the export samples this way; see its configuration.

Assets and custom components

Source-relative images are resolved under the collection roots: sourceRoot, or the same roots list collection used. assetDirs: ["public", "static"] (or repeated --asset-dir) adds URL-root asset directories, so /img/logo.svg can be copied from public/img/logo.svg; with hostUrl configured, the resolver also accepts its base prefix, such as /project/img/logo.svg.

Referenced local images and styles are copied and linked relatively even when hyperlinks use host or none, and so are each srcset candidate, a video's poster, an <object>'s data and the files an inline SVG's <image> or <use> points at. Each file is copied once however many pages and formats use it. Authored external resources remain external.

Normalized native callouts, headings, links and tables render from the collected AST; React and Vue component code is not executed. A custom component that remains in the AST needs an explicit HTML callback, in ESM config or the buildSite API:

const renderOptions = {
  components: {
    ProductMark: () => '<strong class="product-mark">Product</strong>',
  },
}

Add this renderOptions to the site options. Component callbacks return HTML, and the chosen link policy also applies to their output; rendering contracts gives the node and child arguments. An unsupported component fails rather than being silently omitted, and cudoc sanitizes neither source HTML nor renderer output.

Collect feedback on the exported site

mode: "annotate" (or --mode annotate) writes pages that carry a small review-note runtime, so the people who receive a page can send back a wrong sentence or a missing step. The other modes carry none, and the default output has no script at all.

export default {
  sourceRoot: "docs",
  outDir: "review",
  mode: "annotate",
  documents: ["guide.md"],
}

By default each document becomes a single page that carries the runtime as it carries its styles, to send as a file (What a single page carries). For a review that readers open on a static host instead, annotate.target: "hosted" writes a site with the runtime beside its pages:

export default {
  sourceRoot: "docs",
  outDir: "review-site",
  mode: "annotate",
  annotate: {
    target: "hosted",
    reviewId: "guide-review-2026-10",
    inbox: {
      github: {
        repo: "owner/docs",
        template: "cudoc-review.yml",
        field: "notes",
      },
    },
  },
}

reviewId is required there. It names this review's notes in each reader's browser, which keeps them across rebuilds of the site and apart from another review on the same host. A single page derives one from the title and the documents unless it is given.

For the reader. A note is made on a selection or on a block. Select text and press the note button beside the selection, or hover a paragraph, list item, table row or code block and press the + that appears beside it, then type. The note button goes away when you click elsewhere, press Escape or clear the selection, and Tab reaches it from the keyboard.

The speech-bubble button at the bottom right shows how many notes the page has and opens the panel, which lists them with their quotes. A note can be edited, answered, resolved or deleted, and the name field at the top is optional. The panel is in English unless you pick another language in its header, and by default it narrows the page rather than covering the sidebar; both settings are remembered by the browser.

When done, copy a share token for a short list, or open More to download the notes (<page>.annotations.json) or save a copy with notes (<page>.annotated.html). A copy of a single page opens with its styles and notes from any folder; a copy of a hosted page loads its styles only from the folder the original is in. Notes stay in the browser between visits where the browser allows it; Firefox does not for local files, so download before closing.

Sending notes from a hosted review. A static host cannot receive anything, so the notes travel through a place the reader already has. With inbox.github, the panel's Compose on GitHub first says what will be sent: the note text, the quoted passages and the reader's name travel to GitHub in the address, and on a public repository the issue is public. It then opens the repository's new-issue page with the notes filled into the issue form's field (notes by default), and the reader submits the issue there.

Copy the sample issue form into the repository's .github/ISSUE_TEMPLATE/ and name it in template. More notes than an address can hold, past 6,000 characters, are downloaded as JSON instead, to attach to the issue.

For the author. Load the returned .json (or .annotated.html) into your own copy of the site through the load button under More, or append a returned token to your copy's address. The notes then appear where they were made, or marked as position uncertain or not found when the document has changed since. A returned copy whose notes were damaged on the way still opens, says it could not load them, and shows none of them.

cudoc-export annotations maps the notes to the source, to work through them there:

npx cudoc-export annotations review.annotations.json --library .cudoc/documents --out review.md

It writes a Markdown report: for each note the document, the heading, the source line numbers with those lines quoted, and the reviewer's text. A share token, including one from an issue, goes in as --token '<token>' instead of, or next to, the files, and --json gives the same facts as JSON. The report made from the sample shows the layout.

The report is facts only. It contains no instructions of its own, so it can be pasted under your own prompt to an assistant, with the reviewer's words labelled as data rather than as requests; what to do with them stays in your prompt.

What to know before sharing. Five facts to know before sharing and before loading what comes back:

• The page uploads nothing: the runtime has no network access and the page forbids it (connect-src 'none'), so the only way out is the GitHub page a reader opens and submits. On a hosted deployment, add a Content-Security-Policy header such as default-src 'self'; script-src 'self'; style-src 'self'; style-src-attr 'unsafe-inline'; img-src 'self' data:; object-src 'none'; base-uri 'none'; form-action 'none'; connect-src 'none'; frame-ancestors 'none'. style-src-attr keeps the style attributes a page carries, such as a column's min-width from tableColumnWidths.
• A share token carries the note text and names in the address; the panel says so, and on a local file it copies only the #cudoc-notes=… part, never your path.
• Notes stored in the browser include the quoted passages.
• A returned .annotated.html is an HTML file from someone else: open it as you would any attachment that can run code, or load the .json instead.
• Text pulled in by cudoc-embed is not in the embedding document's Markdown, so a note on it is reported as not found.

The file format, the anchoring rules and the report's contract are in the adapter reference.

Share or deploy

A site is a directory: open site/index.html, copy the whole site/ directory to another machine, or upload it to a static host. Choose relative for navigation within the shared directory, host to direct readers to the primary site, or none for reading without clickable links; stylesheets and copied local assets use relative paths either way.

The generated shell needs no client-side fetch, JavaScript or CDN; themeSwitch: true and a hosted review each add local scripts and still no network access. To hand over one page instead, write it with mode: "standalone": the file is the whole page.

Each document page carries a <meta name="description">: the document's front matter description, or its first paragraph that is more than a row of links or an image, cut to 160 characters.

siteUrl (--site-url) tells the build where the site will be served, including any base path. With it every site page names its own address as <link rel="canonical">, a document page in more than one language lists each version under hreflang, and sitemap.xml lists every page. A generated home, which lists a language's documents, has the canonical link and no description or hreflang. siteUrl is this site's address, not the primary site's hostUrl, and applies to mode: "site" only: single pages and review pages have no address of their own, so giving it with another mode is an error.

export default {
  sourceRoot: "docs",
  outDir: "site",
  siteUrl: "https://docs.example.com/manual/",
}

Run the build again to update the output. Keep outDir separate from source, library and asset directories, and use an output directory owned by cudoc. A build that fails leaves the previous output as it was, and a successful one replaces it whole, so no file from an earlier mode or an earlier page is left behind.

Without library, the generated document library is a separate output, by default .cudoc/documents under the output directory's parent (site → .cudoc/documents). With library, that input stays unchanged.

Checks for your deployment

Four checks before sharing, for what the exporter does not verify on its own:

• Confirm collected routes, custom slugs, base paths and hostUrl against the primary site's deployed URLs. The exporter rewrites links but does not check remote availability.
• Copy the whole output directory to a different location and open it with file:// in the browsers your readers use. Check navigation, images, styles, embedded tables and printing. For a single page, open it alone from an empty folder, and build it with strict: true when it must need nothing beside it.
• Inspect host-specific widgets and assets. Dynamic React/Vue code needs an explicit HTML renderer. A css file's url() files are copied or carried inline, but its @import is refused: list each stylesheet in css instead.
• Keep the primary build and HTML output separate. Recollect and prepare before exporting changed documents. Review what the navigation publishes and the result's omitted list before sharing; the navigation decides what is written, but it is not a publication-permission filter for what the documents themselves contain.

The repository's host-library export check verifies all three link policies against five real host libraries and hashes all source, library and primary output files to verify they remain unchanged.

The programmatic API is in buildSite options and behavior.
