plugin-node-uiextension v1.0.0-alpha

UI Extension Plugin for Pattern Lab Node

The UI Extension plugin allows users to customize the Pattern Lab frontend style guide without having to fork styleguide-assets-default. It is intended for styling overrides and navigation additions. If you need anything further, it's suggested that you for the styleguide-assets-default repo and consume your own custom frontend.

Installation

To add the UI Extension Plugin to your project using npm type:

npm install plugin-node-uiextension --save

Or add it directly to your project's package.json file and run npm install

During installation, the plugin is added as a key to the plugins object in your main Pattern Lab project's patternlab-config.json file

If you don't see this object, try running npm run postinstall within the root of your project.

Configuration

Post-installation, you will see the following in your patternlab-config.json:

Example:

"plugins": {
  "plugin-node-uiextension": {
    "enabled": true,
    "initialized": false,
    "options": {
      "stylesheets": [
        "../../../css/pattern-scaffolding.css"
      ],
      "navLinks": {
        "before": [],
        "after": []
      },
      "gearLinks": {
        "before": [],
        "beforeSearch": []
      }
    }
  }
}

CSS

Note the defaulted pattern-scaffolding.css file, which is relative to the installation location within the /public/ output.

At this time, loading external CSS is not supported.

This file is already responsible for meta-styling of your patterns, and is usually only scoped to the viewer <iframe/>. With this default, you now have a useful CSS file for altering both the Pattern Lab UI inside the ish <iframe/>`` as well as the main frontend. You can use a [mockup of Pattern Lab on Codepen](http://codepen.io/bmuenzenmeyer/pen/791da488b2a73909a58eacf801af83d4) to alter the look and feel, and then export or append the **compiled css** back intopattern-scaffolding.css`.

Here's a Pattern Lab light theme quickly created using the CodePen above.

This is also a good way to build custom pattern states and have their colors represented on the UI.

Adding Links

A navLinks and gearLinks object are also initialized post-installation, and allow you to add arbitrary anchor tags to the front end in various locations.

For example, adding the following snippet:

...
"navLinks": {
  "before": [
    { "text": "Voice and Tone", "url": "http://example.com/writing-guide", "class": ""}
  ],
  "after": [
    { "text": "Contribute", "url": "http://example.com/contribute", "class": ""},
    { "text": "Downloads", "url": "http://example.com/resources", "class": ""}
  ]
},
...

would add a link to the Voice and Tone before the main navigation, with a Contribute and Downloads link to follow.

Enabling / Disabling the Plugin

After install, you may manually enable or disable the plugin by finding the plugin-node-uiextension key within your main Pattern Lab project's patternlab-config.json file and setting the enabled flag. In the future this will be possible via CLI.
