Markdown

The MD class provides a set of utilities to work with Markdown and frontmatter text.

The parser also supports markdown variants like MDX.

frontmatter

Extracts and parses the frontmatter text from a markdown file. Returns undefined if no frontmatter is found or if parsing fails. The default format is yaml.

const frontmatter = MD.frontmatter(text, "yaml")

content

Extracts the markdown source without the frontmatter.

const content = MD.content(text)

updateFrontmatter

Merges frontmatter values into the existing markdown file. Use null value to delete fields.

const updated = MD.updateFrontmatter(text, { title: "New Title" })
