Minify and Beautify Plugin for Pattern Lab Node

The Minify HTML Plugin allows Pattern Lab Node users to minify and beautify the HTML template of all patterns. If the right options are passed, HTML errors like empty attributes can be prevented (id="" and class="") and the production code size can be reduced.

Installation

To add the Tab Plugin to your project using npm type:

npm install plugin-node-minify-html --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:

"plugin-node-minify-html": {
    "enabled": true,
    "initialized": false,
    "options": {
        "minify": { },
        "beautify": { },
        "pluginOptions": {
            "verbose": false
        }
    }
}

Minification

The generated HTML will be minified using html-minifier. The following options can be used as an example:

"options": {
  "minify": {
    "removeEmptyAttributes": true,
    "preserveLineBreaks": true,
    "keepClosingSlash": true,
    "removeComments": true,
    "conservativeCollapse": true,
    "collapseWhitespace": true,
    "preserveLineBreaks": true
  },
  ...
},

To use custom html-minifier options pass an object to minify

To disable minification during production mode set the minify option to false.

Beautification

The generated HTML will be beautified using js-beautify. The following options can be used as an example:

"options": {
    ...
    "beautify": {
        "intent_size": 4,
        "end_with_newline": true,
        "inline": true
    }
},

To use custom js-beautify options pass an object to beautify

To disable beatification during production mode set the beautify option to false.

Enabling / Disabling the Plugin

After install, you may manually enable or disable the plugin by finding the plugin-node-minify-html 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.
