mdast
Status: open/active · Aliases: unist
Definition
Section titled “Definition”The markdown AST specification of the unified/remark ecosystem — the de-facto
TypeScript-side standard, extending unist (every node optionally carries
position: {start, end} as {line, column, offset}). The ecosystem’s WASM surface
projects a read-only mdast-compatible JSON view from the internal CST so remark-era
tooling and mental models transfer for free, without constraining the internal
lossless representation. markdown-rs mirrors the same shape in Rust.
