Astrum

Astrum is nolonger actively maintained. We're fans of Storybook which you should check out as an alternative.

Astrum is a lightweight pattern library designed to be included with any web project.

It's non-opinionated and doesn't expect you to write your markup or code in any particular way.

An Astrum pattern library comprises of components organised into groups. Each component has a markup.html and description.md file which are used to render an example of the component along with a code sample. A group can also have an description and is used for organisational purposes. You also have the option to add pages of content, for example an introduction page and/or coding guidelines specific to your project.

Getting Started

Firstly globally install Astrum:

npm install -g astrum

Then from within your project root initialise Astrum into a publicly accessible folder e.g.:

astrum init ./public/pattern-library

Finally add your first component e.g.:

astrum new buttons/default

Your pattern library should now be up and running though granted it will look a little sparse at this stage.

Note

If you are using an IIS setup to serve Astrum, you'll likely have to add the .md MIME type. Further information can be found in this StackOverflow answer.

How Astrum Works

Astrum is a single page, Vue.js powered, app. As mentioned previously, it comprises of components organised into groups and loads its all important data from a core data.json file.

Folder Structure

app                      // Patterns CSS and JavaScript.
components               // Your components.
  buttons                // Example group folder.
    default              // Example component folder.
      markup.html        // Component markup.
      description.md     // Component description.
    description.md.      // Group description.
pages                    // Your pages.
  intro.md               // Example page.
data.json                // Core data file.
favicon.png              // Astrums default favicon.
index.html               // Patterns app index file.
LICENSE.txt              // MIT licence file.

Each group has its own folder under components and each component has its own sub-folder under its parent group.

The data.json File

The data.json file is central to how Astrum works and should be relatively self explanatory upon opening it. By default it looks like this:

{
    "project_logo": null,
    "project_favicon": "favicon.png",
    "project_name": null,
    "project_url": null,
    "copyright_start_year": null,
    "client_name": null,
    "client_url": null,
    "creators": [
        {
            "name": null,
            "url": null
        }
    ],
    "theme": {
        "border_color": "#E0E6ED",
        "highlight_color": "#F9FAFC",
        "brand_color": "#00585C",
        "background_color": "#FFFFFF",
        "code_highlight_theme": "github",
        "override_code_highlight_bg": "#F9FAFC",
        "sample_dark_background": "#333333",
        "show_project_name": true,
        "show_version": true,
        "max-width": null,
        "titles": {
            "library_title": "Pattern Library",
            "pages_title": "Overview",
            "components_title": "Components"
        }
    },
    "assets": {
        "css": [],
        "js": []
    },
    "font_libraries": {
        "typekit_code": null,
        "typography_web_fonts": null,
        "google_web_fonts": null
    },
    "content": {
        "show_first_page_on_load": true,
        "title": "Overview",
        "pages": [
            {
                "name": "introduction",
                "title": "Introduction",
                "file": "./pages/intro.md"
            }
        ]
    },
    "groups": []
}

Let's break it down in details:

Project Details

{
    "project_logo": "/assets/images/logo.svg",
    "project_favicon": "../favicon.png",
    "project_name": "My Project",
    "project_url": "http://myproject.com",
    "copyright_start_year": 2015,
    "client_name": "Best Client Ltd",
    "client_url": "http://bestclient.com",

The more information you add to your data.json file, the more customised the Astrum UI becomes. For example, if you specify a project_logo (this can be a relative path or a full URL), the logo will appear at the top of the sidebar and/or if you specify a client_name along with a copyright_start_year, copyright information will be automatically generated. This will appear at the bottom of the sidebar.

Creators

    "creators": [
        {
            "name": "Ryan Taylor",
            "url": "http://twitter.com/ryanhavoc"
        },
        {
            "name": "Matt West",
            "url": "http://twitter.com/mattantwest"
        }
    ]

You can specify as many creators as you need. Astrum will automatically format these into a "created by" line that appears at the bottom of the sidebar.

Theming

    "theme": {
        "border_color": "#E0E6ED",
        "highlight_color": "#F9FAFC",
        "brand_color": "#00585C",
        "background_color": "#FFFFFF",
        "code_highlight_theme": "github",
        "override_code_highlight_bg": "#F9FAFC",
        "sample_dark_background": "#333333",
        "show_project_name": true,
        "show_version": true,
        "max_width": null,
        "titles": {
            "library_title": "Pattern Library",
            "pages_title": "Overview",
            "components_title": "Components"
        }
    },

Astrum supports basic theming to help you bring your pattern library in line with your projects branding.

Key	Default	Description
border_color	#E0E6ED	The border color used throughout the pattern library, e.g. separating the nav items and around the component containers.
highlight_color	#F9FAFC	The highlight color used throughout the pattern library, .e.g. the background on nav items and the show code sample buttons.
brand_color	#00585C	The primary brand color for your project, used sparing to signify the active nav item as well as and anchors used in your descriptions.
background_color	#FFFFFF	The background color for the whole pattern library.
code_hightlight_theme	github	Astrum uses highlight.js for its code samples. You can use any style you like: available styles
override_code_highlight_bg	#F9FAFC	Allows you to override a highlight.js styles background color.
sample_dark_background	#333333	The color used for dark background component samples.
show_project_name	true	Show the project name in the sidebar.
show_version	true	Show the Astrum version at the bottom of the sidebar.
max_width	null	A maximum width for the components container element.
titles	object	Customise titles that appear on the sidebar. Set a title to null if you'd prefer for it not to be shown at all.

Assets

    "assets": {
        "css": [
            "../assets/css/styles.css"
        ],
        "js": [
            "../assets/js/vendor.js",
            "../assets/js/main.js"
        ]
    },

This is where you specify the CSS and JavaScript for your project, these will be included in your pattern library to render your components.

Font Libraries

    "font_libraries": {
        "typekit_code": null,
        "typography_web_fonts": null,
        "google_web_fonts": null
    },

If your project requires a font service you can specify this here.

Note: For TypeKit you only need to specify the unique code for example: https://use.typekit.net/**dxp5bzu**.js

Content Pages

    "content": {
        "show_first_page_on_load": true,
        "title": "Overview",
        "pages": [
            {
                "name": "introduction",
                "title": "Introduction",
                "file": "./pages/intro.md"
            }
        ]
    },

Astrum includes an introduction page by default.

Key	Default	Description
show_first_page_on_load	true	Display the first page in the `pages` array on load.
title	Overview	The title that appears above the pages navigation in the sidebar.

Add your pages to the pages array, each item requires:

Key	Description
name	The page name, should be lowercase with no spaces. This value is used to set the page’s ID.
title	The page title, this appears in the page navigation in the sidebar.
file	Either created `.md` file in the pages directory and enter the relative path to it or specify a full Url to a markdown file, for example a `README.md` file in a Git repository.

Note: If you don’t require any pages in your pattern library simple set the content key value to null.

Adding Components

The simplest way to add a component to your pattern library is by using the Astrum command-line tool which will ask you a series of questions on how you want the component to be configured. For example:

astrum new navigation/primary

This result of this in your data.json file would be:

    "groups": [
        {
            "name": "navigation",
            "title": "Navigation",
            "components": [
                {
                    "group": "navigation",
                    "name": "primary",
                    "title": "Primary Navigation"
                }
            ]
        }
    ],

The necessary files required for the new component are created for you automatically so now you can add your markup and a component description ready to be displayed in your pattern library.

Component Types

Astrum currently supports two component types. The default component and a colors type. The colors type lets you include a color palette in your pattern library and to include it you use the --type option:

astrum new branding/color-palette --type colors

The result of this in your data.json file would be:

    "groups": [
        {
            "name": "branding",
            "title": "Branding",
            "components": [
                {
                    "group": "branding",
                    "name": "primary-palette",
                    "title": "Primary Color Palette",
                    "type": "colors",
                    "colors": []
                }
            ]
        },
   ],

You’ll need to edit your data.json file further to add your color values, for example:

"colors": [
    "#4c4c4c",
    "#7d8284",
    "#a6b1b5",
    "#e6eaf2",
    "#FFFFFF"
]

You can also add complimentary colors by comma separating the values e.g.:

"colors": [
    "#7da9f9,#507ed3",
    "#f469a7,#c14c80",
    "#60ceb8,#3fa18d",
    "#f5d13f,#f5a63f",
    "#e199e5,#c776cb"
]

Special Options

Components can also have special options that alter their behaviour. To use these add an options key to the component, for example:

{
    "group": "navigation",
    "name": "primary",
    "title": "Primary Navigation",
    "options": {
	      "sample_dark_background": true,
	      "disable_code_sample": true
    }
}

The available options are:

Key	Value	Description
sample_dark_background	boolean	Set the background of the component sample area to be a dark color.
sample_background_color	string	Override sample background color. This option take precident over the dark background color.
sample_min_height	integer	Astrum detects if a component is hidden at desktop or mobile resolutions by detecting the components rendered height. When it’s hidden in your project CSS, Astrum shows a message to this effect. If the component is absolutely positioned, it has no height so you can set a min-height with this option to ensure it is shown properly and Astrum messaging is shown correctly.
sample_overflow_hidden	boolean	Apply `overflow: hidden;` to the component sample.
disabled_auto_sample_hiding	object	Astrum automatically detects if you've hidden a component at mobile or desktop resolutions in your stylesheets. You can disable this feature using this option. Add `show_on_mobile` and `show_on_desktop` keys to the object with boolean values to set how the component should behave.
disable_code_sample	boolean	Don't display the component code sample.

Editing Components

To edit a component use the edit command:

astrum edit branding/primary-palette

Editing Groups

You can also edit a group using the --group option:

astrum edit --group branding

Note: If you change a groups name, Astrum automatically updates all of the groups components.

Listing Components

To see a list of all of the components in your pattern library, you can use the list command:

astrum list

Deleting Components

To delete a component use the delete command:

astrum delete navigation/utility

Deleting Groups

You can also delete an entire group along with all its components using the --group option:

astrum delete --group navigation

Updating Astrum

Firstly update the Astrum package:

npm update -g astrum

Navigate to the route of your project and then update your Astrum instance e.g.:

astrum update

You will receive feedback that the update is complete.

There is also a --force option that you can use to force an update in the event that your Astrum instance is already on the current version. This is if you need to restore your Astrum instance core files.
