Wants to be Jekyll for Dart

Before you read on - check out this video:


Example #

  • Install SiteGen pub global activate sitegen
  • Clone the example from
  • run sitegen -w
  • open another console window and run pub run build_runner serve --delete-conflicting-outputs --live-reload

Play with the sample files...

Support for https-connection!

This is absolutely mandatory if your REST-Server uses HTTP Strict Transport Security (HSTS)

Here you can see the necessary configuration for HTTPS-Support
Generate a self-signed certificate, name it dart.cert and dart.key, place it under

Support for SASS_PATH

Understanding and Using Sass Load Paths

These settings in your .sitegen/site.yaml ()

    sasscompiler: sass
      - "package:zengen"
      - "package:mdl"

generate generate the following SASS_PATH:

sitegen -s

        Loglevel:                  info
        SASS compiler:             sass
        SASS_PATH (only for sass): /Users/mikemitterer/.pub-cache/hosted/

As you can see the first path is resolved to .pub-cache, the second path is resolve to my local working dir where the mdl-library resides

Now you can define your SASS-Import as follows:

    // Imports package:mdl/lib/assets/styles/button/variables
    @import "assets/styles/button/variables";

What it does #

SiteGen is a static site generator in Dart, webserver included. With extra assets-folder and partials-support.
You can write your pages in HTML or Markdown. For Templates Mustache is supported.

A webserver for a quick review is included. On Mac you also get automatic page refresh. On other platforms you could try LivePage chrome extension for maximum productivity.

Here you can see a typical site structure.

Under you can see the result!

Check out the sample! or download the sample as .TGZ.

.sitegen: This is where your (optional) site.yaml lives
This folder is also used to store autgenerated scripts - in the case above you can see the script to refresh Chromium on Mac.

.sitegen/html/_content: This is where SiteGen will look for your files to generate the site from. The following file-formats are supported:

  • .md
  • .markdown
  • .dart
  • .js
  • .json
  • .html
  • .scss
  • .css

.sitegen/html/_data: [optional] This is the place where you can store your data-files.
The following file-formats are supported:

  • .yaml
  • .json

SiteGen injects your data into a global _data variable. Here is a sample how to use such data:


.sitegen/html/_assets: [optional] Additional assets that you don't want to have in _content. For example .scss or .jpg files.

.sitegen/html/_templates: The directory containing your HTML+Mustache templates.

web: Following Dart conventions - this is your default output directory.

site.yaml #

Optional YAML file that stores your global values and config options. Values set here can be accessed from all templates and markdown files.

  author: Mike Mitterer

Can be used in your template (default.html) as


You can also use site.yaml to overwrite your SiteGen default configuration.
Supported vars:

  • content_dir: .sitegen/html/_content
  • template_dir: .sitegen/html/_templates
  • data_dir: .sitegen/html/_data
  • partials_dir: .sitegen/html/_partials
  • assets_dir: .sitegen/html/_assets
  • output_dir: web
  • workspace: .
  • date_format: dd.MM.yyyy
  • yaml_delimeter: ~~~
  • use_markdown: true
  • default_template: default.html
  • sasscompiler: sassc
  • usesass: true
  • autoprefixer: true
  • browser: Chromium
  • talktome: true (on OSX, false on all the other OSs)
  • watchfolder1, watchfolder2 and watchfolder3

Markdown #

SiteGen lets you use markdown to write your site content. At the beginning of each markdown file, you have the option to use a YAML block to define custom values that you can inject into your templates. Example:

title: A Blog Post
published: 01/01/2014
category: example
    - StillShot
    - Rants
    - Etc.
Normal Markdown content here...

As you can see, a line of tildes (~) is used to designate your YAML block. You can access/inject your values into your pages using mustache template syntax. You can do this either inside your dedicated HTML/mustache templates:


Or, you can embed your values within the markdown file itself:

  - __{{.}}__

so you can take advantage of templating and markdown at the same time.

Simply place all your files in your content_dir and SiteGen will generate your site accordingly.
If your markdown file has a .md extension it will be renamed to .html.

Templates #

As mentioned above, you can access any variables set within your markdown files from your templates using mustache. Options set from your site.yaml / site_options can be accessed through the _site variable, like so:


where author is a property defined in your site.yaml / site_options. You can access these values from your markdown or from your html files.

Every page and template has access to the following values:

  • title: title, usually set inside each markdown file, but is set to the name of markdown file if left blank
  • _site: site.yaml values
  • _date: the post/markdown file's last modified date
  • _content: converted markdown content (only accessible from templates)
  • _page.relative_to_root: will be replaced with some '../' depending on the nesting level of your page (check about/index.html)

The default template is 'default.html' but you can overwrite this behavior if you add a 'template' var to the yaml-block of your content file.

template: info_page

Partials #

Files / Directories in your _partials-Folder will be translated into partials-names.
For example: _partials/category/ translates into {{>}}
A partial can be either a .md or a .html file

You can also use partials in the files yaml block:

template: default.html    
dart: ->usage.badge.dart  


If SiteGen finds a .scss file in your output dir (web) it compiles it to the corresponding .css file.
Install instruction for SASS can be found here
In short it's gem install sass and gem install sassc

You can turn off SASS either with --no-usesass or with the appropriate setting in site.yaml

Or - event better, install sassc: brew install sassc

Autoprefixer #

After compiling .SCSS to .CSS SiteGen calls autoprefixer

You can turn off Autoprefixer either with --no-useapfx or with the appropriate setting in site.yaml

Install #


    pub global activate sitegen


    # activate sitegen again
    pub global activate sitegen


    pub global deactivate sitegen

    'Generates all basic files and folders:                'sitegen -i'
    'Observes the default dirs and serves the web-folder:  'sitegen -w --serve'
    'Observes the default dirs and serves the web-folder:  'sitegen -x'
    'Generates the static site in your 'web-folder':       'sitegen -g'

Go to your project root (this is where your pubspec.yaml is) and type:

sitegen -i

This creates a basic file structure for you.

Now type

sitegen -w --serve

This servers your files under http://localhost:8000/

If you are using Chromium on Mac you will get a automatic page refresh for free!

Hints #

  • Just serve a local dir on port 8000 without generating something:
    sitegen --serve --docroot .

  • Sitegen observes automatically it's basefolders like content, web aso. but if you want additional folders that should be observed so that sitegen automatically regenerates it's file - set watchfolder[1-3] in you site.yaml

  • Test your App with Chrome and use sitegen as server (MAC + Linux only)
    pub build && cd build/web && sitegen --serve --port 9000 --docroot . || cd -

    Runs "pub build" - if this runs without errors cd to "build/web" In "build/web" run sitegen as server on port 9000 and set docroot to . (current dir (default would be "web"))
    || means if the prev command ends with an error (Ctrl + C to cancel sitegen)
    jump back where you came from. You should be back in your base folder (where your pubspec.yaml is)
