Authoring with Drizzle

Creating Resources

Drizzle builds static HTML output from source resource files.

  • Pages are compiled against a page layout template and output as HTML files.
  • Patterns are parsed into collections, which are compiled against a collection layout template and output as HTML files.
  • Data files can be used to provide data to patterns and pages.

Front Matter, YAML and JSON

Pages and patterns can use YAML front matter to override defaults, set particular attributes or provide arbitrary local data for the resource during template compilation. In general, data defined in front matter is made available at the top level of compilation (template) context for that resource.

Reserved Properties

Certain properties are reserved at the top level for Drizzle use. Each resource has its own reserved keys as well, but the following keys should not be used in front matter for any resource:

  • contents: Used by Drizzle to store parsed and rendered contents for resources.
  • data: Used for storing pattern- and page-specific data in global objects.
  • drizzle: The drizzle property is reserved for global context during template compilation.
  • outputPath: Used by Drizzle to record where the resource should be output to the file system.
  • path: Used by Drizzle to retain the path to the original resource source file.

Formats and Parsing

Keys and Object Structure

Pages

Each file that matches the pages glob (options.src.pages.glob) will generate an HTML page.

Special Properties
  • layout: Specify the layout template to use for this page resource (default layout templated is defined in options.layouts.page).

Patterns

Special Properties
  • name: Override default naming for the pattern, which is based on filename.
  • hidden: A truthy value will "hide" this pattern, making it available as data, but not rendered on its collection's page.
  • order: Numeric value for where this pattern should appear in its collection's list of patterns. Defaults to alphabetical by filename.
Reserved Properties
  • collection: Used by Drizzle to attach some metadata about this pattern's collection.

Collections

Collections are "meta" resources. Each directory within the glob match for options.src.patterns.glob that contains at least one matching pattern file is considered a "collection." By default, collections are named based on their directory name. One output HTML page is generated per collection.

Collection Metadata (Special Properties)

Creating a file named collection.yaml, collection.yml or collection.json in a pattern directory allows you to override data about that collection. Accepted properties are:

  • name {String}: Override default directory-based naming
  • hidden : An Array of {String} pattern ids to hide in the collection's output (base filename without extension)
  • order: An Array of {String} pattern ids in the order you'd like them to display

hidden and order values can also be defined in individual patterns' front matter. Local pattern data will override data in collection metadata files.

Unlike other resources, properties in collection metadata files that are not one the properties listed here will be ignored.

Reserved Properties
  • items: Used by Drizzle to store all of the patterns in this collection (even hidden ones)
  • patterns: Used by Drizzle to store all of the visible, ordered patterns in this collection.

Data

Files that match options.src.data.globs will be parsed and made available to templates. See documentation about global scope in the templates section.

Templates

Context

The context available to resources during template compilation is a combination of a shared global context and a local context specific to the resource.

Global Context

Templates receive a drizzle data at the top level of their context. Top-level keys on this object are:

  • data: Structured object of parsed data files
  • options: Object of options that drizzle is using
  • pages: Structured object of all page data
  • patterns: Structured object of all patterns
  • templates: Structured object of all templates (partials, layouts) and their contents
Local Context

handlebars-layouts

Default Templates

API

drizzle([options])

  • options {Object}
  • return: Promise resolving to {Object} of build data

options

All options are optional.

beautifier

{Object} of options to pass to js-beautify, which is used to pretty-fy source code.

Default:

beautifier: {
  indent_size: 1,
  indent_char: '	',
  indent_with_tabs: true
}

debug

{Object}

Default:

debug: {
  logFn: console.log
}
  • logFn {Function} that takes a msg argument. Defaults to console.log. You could change this if you wanted messages and errors to go somewhere else.

dest

{Object} of {String} paths for outputting drizzle pages and pattern collection HTML files.

Can be relative to project root.

Default:

dest: {
  pages   : './dist',
  patterns: './dist/patterns'
}

layouts

An {Object} associating different drizzle output page types with their default layout (template). Currently relevant for page and collection. String values correspond to the filename (minus extension) of the layout under the src.templates directory/glob.

Defaults to:

layouts: {
  page      : 'default',
  collection: 'collection'
}

parsers

An {Object} of parser objects for parsing different kinds of source files. Any passed here will extend the default parsers.

@TODO: More docs here

parsers       : parsers

src

{Object} source globs and "basedirs" for different types of drizzle resources.

The glob property is probably more straightforward: that's a glob to match files of that type of resource. The basedir property is directory level to start keying the associated object from—sort of like a "relative path" to use as a root for keying the resources. It should be a {string} that matches one of the directories in the glob expression.

The default value of the src.patterns property, e.g.:

patterns: {
  glob: 'src/patterns/**/*.html',
  basedir: 'patterns'
}

indicates, e.g., that we should consider all pattern resources "relative" to the directory "patterns" and start the keying of the patterns object from there. Note: You can leave basedir alone unless you make significant changes to globs from default.

src properties include:

  • data: data files that contain (typically) YAML or JSON data to make available on drizzleData global context.
  • pages: source page files (typically Handlebars with YAML frontmatter) to transform into HTML pages.
  • patterns: patterns.
  • templates: Handlebars source files—layouts and partials—to be registered as partials on Handlebars. Also made available on the templates property of global data.

Default:

src: {
  data    : {
    basedir: 'src/data',
    glob: 'src/data/**/*'
  },
  pages   : {
    basedir: 'src/pages',
    glob: 'src/pages/**/*'
  },
  patterns: {
    basedir: 'src/patterns',
    glob: 'src/patterns/**/*.html'
  },
  templates: {
    basedir: 'src/templates',
    glob: 'src/templates/**/*'
  }
}

drizzleData

drizzle() returns a Promise resolving to an Object (drizzleData) representing the data about the build.

Properties

  • options: The options the build was ultimately created with.
  • data: Parsed data from data source files.
  • pages: Contents of parsed page source files and their metadata.
  • patterns: Hierarchical structure of patterns, their containing collections and metadata.
  • templates: Contents of parsed layouts and partials.

Development

Useful npm scripts

  • npm build: babel-ize src into dist
  • npm test: build, then run mocha tests
