Include Assets extension for the HTML Webpack Plugin

Enhances html-webpack-plugin functionality by allowing you to specify js or css assets to be included.

When using a plugin such as copy-webpack-plugin you may have assets output to your build directory that are not detected/output by the html-webpack-plugin.

This plugin allows you to force some of these assets to be included in the output from html-webpack-plugin.

Installation

You must be running webpack on node 4.x or higher

Install the plugin with npm:

$ npm install --save-dev html-webpack-include-assets-plugin

Basic Usage

Require the plugin in your webpack config:

var HtmlWebpackIncludeAssetsPlugin = require('html-webpack-include-assets-plugin');

Add the plugin to your webpack config as follows:

plugins: [
  new HtmlWebpackPlugin(),
  new HtmlWebpackIncludeAssetsPlugin({ assets: [], append: true })
]  

Options

The available options are:

• assets: string or array

  Assets that will be output into your html-webpack-plugin template.

  Only assets ending in .js or .css are supported. The presence of assets that do not end in these extensions will cause an error.

• append: boolean

  Specifying whether the assets should be prepended (false) before any existing assets, or appended (true) after them.

• publicPath: boolean or string

  Specifying whether the assets should be prepended with webpack's public path or a custom publicPath (string).

  A value of false may be used to disable prefixing with webpack's publicPath, or a value like myPublicPath/ may be used to prefix all assets with the given string. Default is true.

• hash: boolean

  Specifying whether the assets should be appended with webpack's compilation hash. This is useful for cache busting. Default is false.

• files: string or array

  Files that the assets will be added to.

  By default the assets will be included in all files. If files are defined, the assets will only be included in specified file globs.

Example

Using HtmlWebpackIncludeAssetsPlugin and CopyWebpackPlugin to include assets to html-webpack-plugin template :

plugins: [
  new CopyWebpackPlugin([
    { from: 'node_modules/bootstrap/dist/css', to: 'css/'},
    { from: 'node_modules/bootstrap/dist/fonts', to: 'fonts/'}
  ]),
  new HtmlWebpackPlugin(),
  new HtmlWebpackIncludeAssetsPlugin({
    assets: ['css/bootstrap.min.css', 'css/bootstrap-theme.min.css'],
    append: false
  })
]  

Appending and prepending at the same time :

plugins: [
  new CopyWebpackPlugin([
    { from: 'node_modules/bootstrap/dist/css', to: 'css/'},
    { from: 'node_modules/bootstrap/dist/fonts', to: 'fonts/'}
  ]),
  new HtmlWebpackPlugin(),
  new HtmlWebpackIncludeAssetsPlugin({
    assets: ['css/bootstrap.min.css', 'css/bootstrap-theme.min.css'],
    append: false
  }),
  new HtmlWebpackIncludeAssetsPlugin({
    assets: ['css/custom.css'],
    append: true
  })
]

Using custom publicPath :

plugins: [
  new CopyWebpackPlugin([
    { from: 'node_modules/bootstrap/dist/css', to: 'css/'},
    { from: 'node_modules/bootstrap/dist/fonts', to: 'fonts/'}
  ]),
  new HtmlWebpackPlugin(),
  new HtmlWebpackIncludeAssetsPlugin({
    assets: ['css/bootstrap.min.css', 'css/bootstrap-theme.min.css'],
    append: false,
    publicPath: 'myPublicPath/'
  })
]

Using hash option :

plugins: [
  new CopyWebpackPlugin([
    { from: 'node_modules/bootstrap/dist/css', to: 'css/'},
    { from: 'node_modules/bootstrap/dist/fonts', to: 'fonts/'}
  ]),
  new HtmlWebpackPlugin(),
  new HtmlWebpackIncludeAssetsPlugin({
    assets: ['css/bootstrap.min.css', 'css/bootstrap-theme.min.css'],
    append: false,
    hash: true
  })
]

Specifying specific files

plugins: [
  new CopyWebpackPlugin([
    { from: 'node_modules/bootstrap/dist/css', to: 'css/'},
    { from: 'node_modules/bootstrap/dist/fonts', to: 'fonts/'}
  ]),
  new HtmlWebpackPlugin({
    filename: 'a/index.html'
  }),
  new HtmlWebpackPlugin({
    filename: 'b/index.html'
  }),
  new HtmlWebpackIncludeAssetsPlugin({
    files: ['a/**/*.html'],
    assets: ['css/a.css'],
    append: true
  }),
  new HtmlWebpackIncludeAssetsPlugin({
    files: ['b/**/*.html'],
    assets: ['css/b.css'],
    append: true
  })
]
