Contentlayer is a content SDK that validates and transforms Markdown, MDX, and CMS content into type-safe JSON data you can import directly into your JavaScript/TypeScript application. It offers deep Next.js integration via the next-contentlayer plugin, with a CLI and pluggable content sources such as local files and Notion.

Use cases

• build a type-safe blog with markdown in Next.js
• import MDX content as typed data in my app
• validate frontmatter and generate TypeScript types for content
• use Notion as a CMS for a Next.js site
• speed up static site builds with incremental content processing
• turn local markdown files into queryable JSON documents

When to choose

• you build a Next.js (or similar JS) site with local Markdown/MDX content
• you want type-safe, validated content without learning a query language
• you need fast incremental builds and live reload for content-heavy sites

When to avoid

• you need a framework other than Next.js - Remix, Astro, SvelteKit, and Vite support is only 'considered'
• you need production CMS sources like Contentful or Sanity, which are experimental or planned
• you need a project under heavy active development - the project is in beta/maintenance with known problems
