dulcet-extract-text-webpack-plugin

extract text plugin for webpack

Usage example with css

var ExtractTextPlugin = require("extract-text-webpack-plugin");
module.exports = {
	module: {
		loaders: [
			{ test: /\.css$/, loader: ExtractTextPlugin.extract("style-loader", "css-loader") }
		]
	},
	plugins: [
		new ExtractTextPlugin("styles.css")
	]
}

It moves every require("style.css") in entry chunks into a separate css output file. So your styles are no longer inlined into the javascript, but separate in a css bundle file (styles.css). If your total stylesheet volume is big, it will be faster because the stylesheet bundle is loaded in parallel to the javascript bundle.

Advantages:

• Fewer style tags (older IE has a limit)
• CSS SourceMap (with devtool: "sourcemap" and css-loader?sourceMap)
• CSS requested in parallel
• CSS cached separate
• Faster runtime (less code and DOM operations)

Caveats:

• Additional HTTP request
• Longer compilation time
• Complexer configuration
• No runtime public path modification
• No Hot Module Replacement

API

new ExtractTextPlugin([id: string], filename: string, [options])

• id Unique ident for this plugin instance. (For advanded usage only, by default automatic generated)
• filename the filename of the result file. May contain [name], [id] and [contenthash].
  • [name] the name of the chunk
  • [id] the number of the chunk
  • [contenthash] a hash of the content of the extracted file
• options
  • allChunks extract from all additional chunks too (by default it extracts only from the initial chunk(s))
  • disable disables the plugin

The ExtractTextPlugin generates an output file per entry, so you must use [name], [id] or [contenthash] when using multiple entries.

ExtractTextPlugin.extract([notExtractLoader], loader, [options])

Creates an extracting loader from a existing loader.

• notExtractLoader (optional) the loader(s) that should be used when the css is not extracted (i. e. in a additional chunk when allChunks: false)
• loader the loader(s) that should be used for converting the resource to a css exporting module.
• options
  • publicPath override the publicPath setting for this loader.

There is also a extract function on the instance. You should use this if you have more than one ExtractTextPlugin.
