@snowpack/plugin-webpack

Use Webpack to bundle your application for production.

Install

npm install --save-dev @snowpack/plugin-webpack

Usage

Add @snowpack/plugin-webpack to snowpack.config.json:

{
  "plugins": [
    [
      "@snowpack/plugin-webpack",
      {
        /* see "Plugin Options" below */
      }
    ]
  ]
}

or to snowpack.config.js:

module.exports = {
  plugins: [
    [
      '@snowpack/plugin-webpack',
      {
        /* see "Plugin Options" below */
      },
    ],
  ],
};

The options object is optional.

Default Build Script

{
  "scripts": {"bundle:*": "@snowpack/plugin-webpack"}
}

Plugin Options

• sourceMap: boolean - Enable sourcemaps in the bundled output.
• outputPattern: {css: string, js: string, assets: string} - Set the URL for your final bundled files. This is where they will be written to disk in the build/ directory. See Webpack's output.filename documentation for examples of valid values.
• extendConfig: (config: WebpackConfig) => WebpackConfig - extend your webpack config, see below.
• manifest: boolean | string - Enable generating a manifest file. The default value is false, the default file name is ./asset-manifest.json if setting manifest to true. The relative path is resolved from the output directory.
• htmlMinifierOptions: boolean | object - See below.

Extending The Default Webpack Config

The extendConfig option is a function that you can provide to configure the default webpack config. If you provide this function, the plugin will pass its return value to webpack.compile(). Use this to make changes, add plugins, configure loaders, etc.

Note that this requires you use a snowpack.config.js JavaScript config file. JSON configuration cannot represent a function.

// snowpack.config.js
module.exports = {
  plugins: [
    [
      '@snowpack/plugin-webpack',
      {
        extendConfig: (config) => {
          config.plugins.push(/* ... */);
          return config;
        },
      },
    ],
  ],
};

Minify HTML

With htmlMinifierOptions you can either disable the minification entirely or provide your own options.

// snowpack.config.js
module.exports = {
  plugins: [
    [
      '@snowpack/plugin-webpack',
      {
        htmlMinifierOptions: false, // disabled entirely,
      },
    ],
  ],
};

The default options are:

{
  collapseWhitespace: true,
  removeComments: true,
  removeEmptyAttributes: true,
  removeRedundantAttributes: true,
  removeScriptTypeAttributes: true,
  removeStyleLinkTypeAttributes: true,
}
