Extract YAML front matter from strings.

This modules does not do any IO (file loading or reading), only extracting yaml front matter from strings.

This concept that was originally introduced to me through the jeykll blogging system and is pretty useful where you want to be able to easily add metadata to content without the need for a database. YAML is extracted from the the top of a file between matching separators of "---" or "= yaml =".

So you have a file example.md:

---
title: Just hack'n
description: Nothing to see here
---

This is some text about some stuff that happened sometime ago

Then you can do this:

var fs = require('fs')
  , fm = require('front-matter')

fs.readFile('./example.md', 'utf8', function(err, data){
  if (err) throw err

  var content = fm(data)

  console.log(content)
})

And end up with an object like this:

{ attributes: { title: 'Just hack\'n'
  , description: 'Nothing to see here'
  }
, body: 'This is some content'
}

var fm = require('front-matter')

Return a content object with two properties:

• content.attributes contains the extracted yaml attributes in json form
• content.body contains the string contents below the yaml separators

With npm do:

npm install front-matter
