webpack-handle-css-loader

This is a short-hand module for adding css and extracting css support.

Install

yarn add webpack-handle-css-loader

# If you want to extract CSS
# Install this plugin as well
yarn add mini-css-extract-plugin

Usage

const HandleCSSLoader = require('webpack-handle-css-loader')
const MiniCssExtractPlugin = require('mini-css-extract-plugin')

const isProd = process.env.NODE_ENV === 'production'

const handleLoader = new HandleCSSLoader({
  minimize: isProd,
  extract: isProd,
  sourceMap: false,
  cssModules: false
})

module.exports = {
  module: {
    rules: [
      // Handle .css files with css-loader & postcss-loader
      handleLoader.css(),
      // Handle .sass files
      // Similar to above but add sass-loader too
      handleLoader.sass()
    ]
  },
  plugins: [
    isProd && new MiniCssExtractPlugin({
      // Options similar to the same options in webpackOptions.output
      // both options are optional
      filename: "[name].css",
      chunkFilename: "[id].css"
    })
  ].filter(Boolean)
}

Note:

We add postcss-loader to each rule, which means in handleLoader.css() you got something like ['style-loader', 'css-loader', 'postcss-loader'], see here for how to disable it or set options for it.
