remark-metadata

Adds meta data about a Markdown file to a Markdown file, formatted as Front Matter.

The following meta data is added:

• lastModifiedAt using one of the following heuristics:
  1. the vFile has the property data.lastModifiedAt defined
  2. if git exists, the commit time of the file
  3. the mtime reported by Node's stat method.

Installation

$ npm install remark-metadata

Requires remark-frontmatter.

Usage

Given a file, example.md, which contains the following Markdown:

---
title: Example
---

# Example

This is an example

Using remark like follows:

var vfile = require('to-vfile');
var remark = require('remark');
var frontmatter = require('remark-frontmatter');
var metadata = require('remark-metadata');

var example = vfile.readSync('example.md');

remark()
  .use(frontmatter)
  .use(metadata, { git: true })
  .process(example, function (err, file) {
    if (err) throw err;
    console.log(String(file))
    })
  });

This will output the following Markdown:

---
title: Example
lastModifiedDate: 'Tue, 28 Nov 2017 02:44:25 GMT'

---
