Parses and validates Markdown frontmatter (YAML) to file.data.frontmatter.

Validation is done by revalidator.

Built for Remark 12, won't work with Remark 13. Requires remark-frontmatter.

Example

example.js:

const processor = remark()
  .use(require("remark-frontmatter"))
  .use(require("remark-parse-frontmatter"))
  .freeze();

const file = processor.processSync(`
---
title: Hello, World!
---
`);

console.log(file.data.frontmatter);

Output:

{
  title: "Hello, World!"
}
