metalsmith-permalinks

npm version code style: prettier metalsmith: plugin

Build Status

A Metalsmith plugin that applies a custom permalink pattern to files, and renames them so that they're nested properly for static sites (converting about.html into about/index.html).

Installation

$ npm install metalsmith-permalinks

Usage

var Metalsmith = require('metalsmith');
var permalinks = require('metalsmith-permalinks');
 
var metalsmith = new Metalsmith(__dirname).use(
  permalinks({
    pattern: ':title'
  })
);

The pattern can contain a reference to any piece of metadata associated with the file by using the :PROPERTY syntax for placeholders.

If no pattern is provided, the files won't be remapped, but the path metadata key will still be set, so that you can use it for outputting links to files in the template.

The pattern can also be a set as such:

var Metalsmith = require('metalsmith');
var permalinks = require('metalsmith-permalinks');
 
var metalsmith = new Metalsmith(__dirname).use(
  permalinks({
    // original options would act as the keys of a `default` linkset,
    pattern: ':title',
    date: 'YYYY',
 
    // each linkset defines a match, and any other desired option
    linksets: [
      {
        match: { collection: 'blogposts' },
        pattern: 'blog/:date/:title',
        date: 'mmddyy'
      },
      {
        match: { collection: 'pages' },
        pattern: 'pages/:title'
      }
    ]
  })
);

Dates

By default any date will be converted to a YYYY/MM/DD format when using in a permalink pattern, but you can change the conversion by passing a date option:

metalsmith.use(
  permalinks({
    pattern: ':date/:title',
    date: 'YYYY'
  })
);

It uses moment.js to format the string.

Custom 'slug' function

If you do not like filenames, you can replace slug function. For now only js version of syntax is supported and tested.

metalsmith.use(
  permalinks({
    pattern: ':title',
    slug: require('transliteration').slugify
  })
);

There are plenty on npm for transliteration and slugs. https://www.npmjs.com/browse/keyword/transliteration, better than default slug-component.

Relative Files

When this plugin rewrites your files to be permalinked properly, it will also duplicate sibling files so that relative links like /images/cat.gif will be preserved nicely. You can turn this feature off by setting the relative option to false.

For example for this source directory:

src/
  css/
    style.css
  post.html

Here's what the build directory would look like with relative on:

build/
  post/
    index.html
    css/
      style.css
  css/
    style.css

And here's with relative off:

build/
  post/
    index.html
  css/
    style.css

relative can also be set to folder, which uses a strategy that considers files in folder as siblings if the folder is named after the html file.

For example using the folder strategy with this source directory:

src/
  post.html
  post/
    image.jpg

Here's what the build directory would look like with relative set to folder:

build/
    index.html
    image.jpg

Skipping Permalinks for a file

A file can be ignored by the metalsmith-permalinks plugin if you pass the permalink: false option to the yaml metadata of a file. This is useful for hosting a static site on AWS S3, where there is a top level error.html file and not an error/index.html file.

For example, in your error.md file:

---
template: error.html
title: error
permalink: false
---

Slug Options

slug is used for slugifying strings and it's set to lower-case mode by default.

You can pass custom slug options:

metalsmith.use(
  permalinks({
    slug: {
      replacement: '_',
      lower: false
    }
  })
);

Overriding the permalink for a file

Using the permalink property in a file's front-matter, its permalink can be overridden. This can be useful for transferring projects over to Metalsmith where pages don't follow a strict permalink system.

For example, in one of your pages:

---
title: My Post
permalink: "posts/my-post"
---

CLI

You can also use the plugin with the Metalsmith CLI by adding a key to your metalsmith.json file:

{
  "plugins": {
    "metalsmith-permalinks": {
      "pattern": ":title"
    }
  }
}
