HTML

The @tanstack/markdown/html entry exports the HTML renderer without React.

import {
  renderBlock,
  renderDocument,
  renderHtml,
  renderInline,
} from '@tanstack/markdown/html'

renderHtml

function renderHtml(
  input: MarkdownInput,
  options?: RenderOptions,
): string

Parses string input when necessary and renders all document children joined by newlines.

renderDocument

function renderDocument(
  document: MarkdownDocument,
  options?: RenderOptions,
): string

Renders an existing document. This is an alias with a narrower input type.

renderBlock

function renderBlock(
  node: BlockNode,
  options?: RenderOptions,
): string

Runs extension HTML hooks, then renders one block node.

renderInline

function renderInline(
  node: InlineNode,
  options?: RenderOptions,
): string

Runs extension HTML hooks, then renders one inline node.

Render options

RenderOptions includes every ParseOptions field plus:

Option	Default	Behavior
highlighter	none	Return trusted HTML for code contents
codeLineNumbers	unset	Forward the line-number preference to the highlighter
headingAnchors	false	Append default or configured links to headings with IDs

When rendering a pre-parsed document, parse-only options do not retroactively change its AST. Renderer options and extension renderHtml hooks still apply.
