remark-parse-yaml

This remark plugin takes markdown with yaml frontmatter and parses the yaml into an object.

Usage

const unified = require('unified')
const markdown = require('remark-parse')
const frontmatter = require('remark-frontmatter')
const parseFrontmatter = require('remark-parse-yaml');

let processor = unified()
    .use(markdown)
    .use(frontmatter)
    .use(parseFrontmatter)

When the processor is run, yaml nodes will now have an additional key, parsedValue, attached to its data key.
Say that we have this markdown string:

``` markdown

metadata: this is metadata tags:

- one
- two

---

When parsed, this will produce a `yaml` node with a `data` object that looks like this:

```javascript
data: {
    parsedValue: {
        metadata: "this is metadata",
        tags: ["one", "two"]
    }
}
