Package Exports

front-matter

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (front-matter) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

front-matter

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 =".

Install

With npm do:

npm install front-matter

Example

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 text about some stuff that happened sometime ago'
}

Methods

var fm = require('front-matter')

fm(string)

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

fm.test(string)

Check if a string contains a front matter header of "---" or "= yaml =". Primarily used internally but is useful outside of the module.

Returns true or false

fm.test(string) #=> true || false
