Metalsmith

An extremely simple, pluggable static site generator.

In Metalsmith, all of the logic is handled by plugins. You simply chain them together.

How does it work?

Metalsmith works in three simple steps:

  1. Read all the files in a source directory.
  2. Invoke a series of plugins that manipulate the files.
  3. Write the results to a destination directory!

Each plugin is invoked with the contents of the source directory, and each file can contain YAML front-matter that will be attached as metadata, so a simple file like…

---
title: A Catchy Title
date: 2014-12-01
---

An informative article.

…would be parsed into…

{
  'path/to/my-file.md': {
    title: 'A Catchy Title',
    date: new Date('2014-12-01'),
    contents: new Buffer('An informative article.')
  }
}

…which any of the plugins can then manipulate however they want. And writing the plugins is incredibly simple, just take a look at the example drafts plugin.

Of course they can get a lot more complicated too. That’s what makes Metalsmith powerful; the plugins can do anything you want!

The secret…

We keep referring to Metalsmith as a “static site generator”, but it’s a lot more than that. Since everything is a plugin, the core library is actually just an abstraction for manipulating a directory of files.
