Layout Loader

Wraps markdown files in a jade layout.

How it works

Layout loader works by extending the layout of your choice and injecting the markdown in a :marked filter. See below.

extends ${layout}

block ${block}
  :marked
    ${content}

Installation

Load it in app.js like so:

module.exports = {
  posthtml: (ctx) => {
    return {
      defaults: [
        jade({ filename: ctx.resourcePath })
      ]
    }
  },
  matchers: {
    html: '**/*.(md|jade)',
  },
  module: {
    preLoaders: [
      { test: /\.md$/, loader: 'layout-loader', layout: 'my-layout' }
    ]
  },
}

Configuration

Layout loader has two configuration options.

1. The layout to extend. Defaults to markdown.
2. The block to override. Defaults to content.

Options can ether be a string or a function returning a string (called with the file path). Layout loader will check the following locations for configuration:

1. A property call options on the loader object.
2. The loader object its self.

Examples

The following are valid configurations.

preLoaders: [
  { test: /\.md$/, loader: 'layout-loader', layout: 'my-layout' }
]

preLoaders: [
  { test: /\.md$/, loader: 'layout-loader', layout: (path) => 'bingo' }
]

preLoaders: [
  {
    test: /\.md$/,
    loader: 'layout-loader',
    options: {
      layout: 'layout'
      block: 'text'
    }
  }
]

Using with front matter

Layout Load was primarily built to be used with spike-front-matter. Here is how to integrate the two.

Option 1

const FrontMatter = require('spike-front-matter')
let fm = new FrontMatter()

module.exports = {
  posthtml: (ctx) => {
    return {
      defaults: [
        jade({ filename: ctx.resourcePath, page: fm.page, site: fm.site}),
      ]
    }
  },
  plugins: [
    fm
  ],
  matchers: {
    html: '**/*.(md|jade)',
  },
  module: {
    preLoaders: [
      { test: /\.md$/, loader: 'layout-loader', options: fm.page, layout: 'default' }
    ]
  }
}

Option 2

const FrontMatter = require('spike-front-matter')
let fm = new FrontMatter()

module.exports = {
  posthtml: (ctx) => {
    return {
      defaults: [
        jade({ filename: ctx.resourcePath, page: fm.page, site: fm.site}),
      ]
    }
  },
  plugins: [
    fm
  ],
  matchers: {
    html: '**/*.(md|jade)',
  },
  module: {
    preLoaders: [
      { test: /\.md$/, loader: 'layout-loader', layout: () => fm.page.layout }
    ]
  }
}
