Sync any Notion database to local markdown, MDX, or JSON files.

• One command sync. Point nts at a Notion database and get structured content files with full frontmatter.
• All block types. Paragraphs, headings, images, callouts, columns, tables, equations, toggles, synced blocks, bookmarks, video, audio, file, PDF, embeds.
• Incremental updates. Track what changed since the last sync. Only re-fetch updated pages.

Install

npm install -g notion-to-site

Quick start

1. Create a Notion integration

Go to notion.so/my-integrations and create an internal integration. Copy the API key.

2. Share your database

Open your Notion database, click the ... menu, then "Connections", and add your integration.

3. Create a config file

nts init

This creates nts.config.js in your project. Open it and set your database ID:

// nts.config.js
export default {
  database: 'your-database-id-here',
  output: './content',
  adapter: 'markdown',
  author: 'Your Name',
  linkPrefix: '/blog',
  images: { download: true, outputDir: './public/images', format: 'webp', quality: 80 },
  schema: { strict: false },
  sync: { concurrency: 5, deletions: true },
  content: { toc: false, stripBackLinks: true },
}

4. Set your API key and sync

export NOTION_API_KEY=ntn_your_key_here
nts sync

Your content files will appear in ./content.

Each synced page produces a file with YAML frontmatter and rendered content. Here is a sample:

Frontmatter fields

• id -- The slug, derived from the page title or a custom Slug property in Notion.
• path -- Relative file path in the output directory.
• type -- From the Type/Kind property in Notion, defaults to post.
• created / last_updated -- Dates from Notion page metadata.
• source.page_id -- The original Notion page ID for traceability.
• meta.seo_title -- From an SEO Title property, or falls back to the page title.
• meta.description -- From a Description property, or auto-extracted from the first paragraph.
• meta.language -- From a Language property, or auto-detected from the content.
• meta.reading_time -- Estimated minutes to read (200 words/minute).
• meta.word_count -- Total word count of the content body.

Framework guides

Next.js

Place your config output in ./content and use a library like gray-matter to parse frontmatter at build time. If you use contentlayer or next-mdx-remote, set adapter: 'mdx' and point the output to your content directory. Images go in ./public/images by default, so they are served statically.

Astro

Astro's content collections work well with the markdown adapter. Set output to ./src/content/blog and define a matching collection schema in src/content/config.ts. Astro will pick up the frontmatter fields automatically. Use adapter: 'mdx' if your pages use components.

SvelteKit

Use mdsvex for markdown processing. Set output to a directory your routes can import from, and parse frontmatter with gray-matter in your +page.ts load function. The JSON adapter (adapter: 'json') is also a good fit if you prefer to load content as data rather than rendered markup.

How it works

nts connects to the Notion API, fetches every page in your database, and converts each one to markdown using custom block-type renderers. It extracts metadata from Notion page properties (title, tags, status, author, etc.), builds structured frontmatter, resolves internal links between pages, and writes the result to your chosen output format.

Environment variables

You can set this in a .env or .env.local file in your project root. Both are loaded automatically.
