用于大型语言模型上下文的网页到Markdown提取引擎（ChatGPT、Claude、Gemini）。 @page2ai/mcp 服务器的引擎。该 Page2AI Chrome 和 Firefox 扩展各自运行 浏览器中的流水线（见下文）。 保留带有语言提示、表格和阅读结构的代码块。 零遥测，MIT授权。

它在Node.js（通过LinkedIn）和浏览器中都能正常工作。

• Node.js：htmlToMarkdown(html, opts) 或 fetchAndConvert(url, opts) — 零外部 API 调用，使用 Linkedom 进行解析
• 浏览器：导出BrowserAdapter和PageAdapter接口;完整的提取流水线存储在扩展仓库中（计划进行迁移）
• 零数据收集：无遥测，无分析，无第三方电话
• MIT 持证

API

htmlToMarkdown(html, opts?)

将HTML字符串转换为Markdown。同步。

• html（字符串）——解析的HTML：完整文档或片段（HTMX部分文件、模板摘要、纯文本）
• opts.baseUrl（字符串）——用于解析相对链接的URL（默认：'about:blank'）
• ‘选择’。

@page2ai/core

Webpage-to-Markdown extraction engine for LLM context (ChatGPT, Claude, Gemini). The engine of the @page2ai/mcp server. The Page2AI Chrome & Firefox extensions run their own pipeline in the browser (see below). Preserves code blocks with language hints, tables, and reading structure. Zero telemetry, MIT-licensed.

Works in Node.js (via linkedom) and in browsers.

• Node.js: htmlToMarkdown(html, opts) or fetchAndConvert(url, opts) — zero external API calls, uses linkedom for parsing
• Browser: exports BrowserAdapter and the PageAdapter interface; the full extract pipeline lives in the extension repo (a migration is planned)
• Zero data collection: no telemetry, no analytics, no third-party calls
• MIT licensed

Install

npm install @page2ai/core

Quick start

import { htmlToMarkdown, fetchAndConvert } from '@page2ai/core';

// From an HTML string
const html = `HelloWorld`;
const { markdown, title, charCount } = htmlToMarkdown(html, {
  baseUrl: 'https://example.com/hello',
  includeFrontmatter: true,
});
console.log(markdown);

// From a URL
const result = await fetchAndConvert('https://docs.anthropic.com/en/api/messages', {
  timeoutMs: 15000,
});
console.log(result.markdown);

API

htmlToMarkdown(html, opts?)

Converts an HTML string to Markdown. Synchronous.

• html (string) — the HTML to parse: a whole document or a fragment (an HTMX partial, a template snippet, plain text)
• opts.baseUrl (string) — URL used to resolve relative links (default: 'about:blank')
• opts.profile (string) — accepted, but ignored by the Node build in this version: 'dashboard', 'marketing' and the rest produce the same output here. The profiles switch the browser extension’s live-page pipeline (clicking tabs, waiting for lazy content), which the Node renderer does not run
• opts.includeFrontmatter (boolean) — emit YAML frontmatter block (default: true)
• opts.includeImages (boolean) — emit image links (default: true). Inside a table cell, a layout table’s included, an image is written as its alt text either way, and an image with an empty alt or aria-hidden="true" adds nothing
