Tidy HTML for HTML Webpack Plugin

Very bare bones HTML tidy plugin for HTML webpack plugin.

Enhances html-webpack-plugin functionality by using htmltidy after processing HTML

Can be used in conjunction with other plugins for html-webpack-plugin.

Installation

You must be running webpack (1.x, 2.x or 3.x) on node 4+.

Install the plugin with npm:

npm install --save-dev tidy-html-webpack-plugin

Basic Usage

Add the plugin to your webpack config as follows:

plugins: [
  new HtmlWebpackPlugin(),
  new TidyHtmlWebpackPlugin()
]

The order is important - the plugin must come after HtmlWebpackPlugin.

The above configuration will tidy the HTML to the default configuration spec.

Configuration

Configuration offers more granular control:

See full documentation at tidy.sourceforge.net

In general, all options in documentation in the format 'hide-comments', can be used in the 'tidy' property of the config as lower camel case 'hideComments'

eg.

let config = {
  tidy: {
    hideComments: true,
    tabSize: 2
  }
};

Default plugin configuration (also htmltidy's defaults):

{
  tidy: {
    doctype: 'html5',
    hideComments: true,
    indent: true,
    newBlocklevelTags: 'app-root',
    sortAttributes: 'alpha',
    tabSize: 2,
    wrap: 0
  },
  disabled: false,
}

Important

The tidy plugin will remove any unknown html tags from your html, so to prevent this from happening you must add any new tag names to either the 'newBlocklevelTags', 'newInlineTags' or 'newEmptyTags', depending on the tag spec, to the 'tidy' part of the config.

Use case:

If your angular/react app contains the root element as a <app-root></app-root> tag, HtmlTidy won't recognise it as a tag and will remove it.

To prevent this just add it to the config like this and html tidy will format it as such:

plugins: [
  new HtmlWebpackPlugin(),
  new TidyHtmlWebpackPlugin({
    tidy: {
      newBlocklevelTags: 'app-root'
      // or comma separated for multiple
      // 'app-header, app-body, app-footer'
    }
  })
]

Configuration Examples

Change tab size:

plugins: [
  new HtmlWebpackPlugin(),
  new TidyHtmlWebpackPlugin({
    tidy: {
      indent: true,
      tabSize: 2
    }
  })
]

Remove comments:

plugins: [
  new HtmlWebpackPlugin(),
  new TidyHtmlWebpackPlugin({
    tidy: {
      hideComments: true
    }
  })
]

Sort attributes:

plugins: [
  new HtmlWebpackPlugin(),
  new TidyHtmlWebpackPlugin({
    tidy: {
      sortAttributes: 'alpha'
    }
  })
]

Disable plugin (useful for dynamic configuration setups):

plugins: [
  new HtmlWebpackPlugin(),
  new TidyHtmlWebpackPlugin({
    disable: true
  })
]
