Notion as a CMS

Language: JavaScript

Version: 2.0.0

Overview

Notion-as-CMS is a lightweight, edge-ready middleware library that allows developers to use Notion as a fully-featured headless Content Management System. By wrapping the official Notion API, this project abstracts away the complexities of block parsing, pagination, and rate-limiting, delivering clean, structured JSON payloads directly to frontend applications like React, Vue, or Svelte.

Core Problem Solved

Notion provides an incredible, collaborative editing experience that non-technical users love. However, using the Notion API directly in production frontends is fraught with issues: the API responses are heavily nested (requiring complex recursive parsing to render rich text), it is subject to strict rate limits, and fetching a single page often requires multiple waterfall network requests.

This project solves this by providing a unified fetching and parsing layer. It traverses Notion's block tree, converts it into a simplified AST (Abstract Syntax Tree) or direct HTML/Markdown, and implements aggressive caching strategies suitable for Edge environments (like Cloudflare Workers or Vercel Edge Functions).

Key Features

Block-to-HTML/Markdown Parser: Automatically converts complex Notion blocks (paragraphs, headings, toggles, callouts, code blocks, and images) into semantic HTML or clean Markdown.
Database Querying Wrapper: Simplifies database filtering and sorting, allowing developers to query Notion tables just like a traditional SQL/NoSQL database.
Edge Caching: Designed to run in serverless environments with built-in support for stale-while-revalidate caching patterns, completely neutralizing the Notion API's latency and rate limits.
Image Optimization Handling: Intercepts Notion's expiring AWS S3 image URLs and proxies them, allowing frontend frameworks to optimize and cache the assets permanently.

Technologies Used

JavaScript / TypeScript: Core middleware logic.
@notionhq/client: Official Notion API SDK.
Serverless / Edge Compute: Architected specifically for deployment on Vercel, Netlify, or Cloudflare Workers.
