mdast is a specification for representing Markdown as an abstract syntax tree, extending the unist syntax tree format. It supports multiple Markdown flavors such as CommonMark and GitHub Flavored Markdown, with a rich ecosystem of JavaScript utilities.

Use cases

• parse markdown into a syntax tree
• transform markdown documents programmatically
• represent CommonMark or GFM as structured data
• build markdown linting or analysis tools
• convert markdown to HTML or other formats
• write custom markdown extensions or plugins

When to choose

• you need a standardized, well-specified AST for markdown
• you are building tools in the unified/remark ecosystem
• you need to inspect, transform, or generate markdown programmatically
• you want TypeScript types for markdown syntax trees

When to avoid

• you just need to render markdown to HTML with no tree manipulation
• you need a parser for a non-markdown format
• you want a ready-made CLI rather than a specification and library ecosystem
