API Reference

🖥️

Truly Headless

Runs anywhere Node.js (≥ 18) or Bun runs — servers, CI, edge functions. No browser or Puppeteer required.

📐

Deterministic Layout

Same Markdown always produces pixel-identical output across machines and runs.

⚡

Fast at Scale

PNG at ~99 ms/page, SVG at ~6 ms/page. Batch hundreds of pages per second with parallel rendering.

🔢

LaTeX Math

Block and inline formulas rendered server-side via MathJax. Colors follow the active theme automatically.

🎨

10 Built-in Themes

Light and dark themes including GitHub, Nord, Dracula, Solarized, and more. Full override API for custom themes and gradient backgrounds.

✨

Syntax Highlighting

Fenced code blocks highlighted by Shiki. Theme auto-detected from page background — dark pages get dark code themes.

📄

Pagination Built-in

Automatically paginates content into fixed-size pages, or renders everything into a single tall image.

🤖

Agent-ready CLI

JSON output mode makes the CLI easy to use from scripts and AI agents. Install the Claude Code skill for marknative-aware agents.

Quick Start

CLINode.js / Bun

bash

# Install globally
npm install -g marknative

# Render a file → page-01.png, page-02.png … next to the source
marknative README.md

# Dark theme, single image
marknative README.md -t dark --single-page -o preview.png

# JSON output for scripts / agents
marknative README.md --json

import { renderMarkdown } from 'marknative'

const pages = await renderMarkdown(`
# Hello, marknative

Produces **paginated PNG pages** without a browser.
`)

for (const [i, page] of pages.entries()) {
  await Bun.write(`page-${i + 1}.png`, page.data)
}
