parser-front-matter

Front matter parsing middleware based on gray-matter, providing a callback-oriented API for parsing YAML-like front matter from strings or file objects. Version 1.6.4 is the latest stable release, with no major updates since 2019. It supports both async (parse) and sync (parseSync) methods, and is designed for use with build tools like assemble, verb, or generate. Unlike direct gray-matter usage, this package integrates via middleware conventions, but it is slow, unmaintained, and lacks TypeScript definitions.
