Velite

Velite is a content framework that transforms Markdown/MDX, YAML, JSON, and other files into a type-safe data layer for applications. Version 0.3.1 (released February 2025) requires Node ^18.20.0 || >=20.3.0. It provides a CLI and API to define schemas using TypeScript/Zod, generating fully typed data for frontend usage. Compared to Contentlayer, Velite is actively maintained, offers a simpler setup, and supports more file types out of the box. It uses esbuild for fast builds and is designed for modern JavaScript/TypeScript projects.
