Access yaml frontmatter

[strass]

Is it possible to access the yaml frontmatter? I'd like to be able to set some details and tags up there

You mean like loading a markdown file or something that contains YAML frontmatter and extracting that part?

I know a lot of markdown or other markup-like parsers can do that, not sure if js-yaml can. If there is a way to do that without introducing too many dependencies, I think it would be useful.
