Mdast

Mdast is a Markdown Abstract Syntax Tree (AST) specification and ecosystem for parsing, transforming, and serializing Markdown content in JavaScript. It provides a structured tree representation of Markdown documents, enabling programmatic manipulation and analysis. The ecosystem includes parsers, compilers, and plugins to work with Markdown in a flexible and extensible way.

Also known as: Markdown AST, mdast-js, mdast ecosystem, mdast spec, Markdown abstract syntax tree

Why learn Mdast?

Developers should learn Mdast when building tools that process Markdown, such as static site generators, documentation systems, or content management systems, as it allows for precise control over Markdown parsing and output. It is particularly useful for tasks like linting, formatting, or converting Markdown to other formats (e.g., HTML, PDF) with custom transformations.
