Webpack 3.11 - ExtractTextPlugin - You may need an appropriate loader to handle this file type - Unexpected token

Question

I like the error messages, they are very helpful (irony off)

Error-Message:

webpack.config.js, example code taken from webpack.js.org v3.11

const ExtractTextPlugin = require('extract-text-webpack-plugin');

// Create multiple instances
const extractCSS = new ExtractTextPlugin('stylesheets/[name]-one.css');
const extractLESS = new ExtractTextPlugin('stylesheets/[name]-two.css');

module.exports = {
  module: {
    rules: [
      {
        test: /\.css$/,
        use: extractCSS.extract([ 'css-loader', 'postcss-loader' ])
      },
      {
        test: /\.less$/i,
        use: extractLESS.extract([ 'css-loader', 'less-loader' ])
      },
    ]
  },
  plugins: [
    extractCSS,
    extractLESS
  ]
};

It looks like it's failing on `index.ts`. Have you tried adding a rule for `ts-loader`? E.g., `{test: /\.ts$/, use: 'ts-loader'}`. More details on the [GitHub page](https://github.com/TypeStrong/ts-loader). — Mike Hill, Feb 14 '18 at 23:10
the `.ts` file is fine, it is something with the configuration... the error messages are misleading. It could also spit out "New York, the weather is shiny", this would be the equivalent of the above error message... — Legends, Feb 15 '18 at 00:06

Works with Webpack v3.11

I made some changes to the webpack.config.js, take a look below:

const {
    join
} = require('path')


const webpack = require('webpack');
var ExtractTextPlugin = require("extract-text-webpack-plugin")

const extractLESS = new ExtractTextPlugin({
    filename: 'stylesheets/[name]-two.css',
    disable: false,
    allChunks: true
});
const extractCSS = new ExtractTextPlugin('stylesheets/[name]-one.css');

module.exports = {

    devtool: 'inline-source-map',

    entry: join(__dirname, 'src/index'),

    plugins: [
        extractCSS,
        extractLESS 
    ],

    devtool: "source-map",

    output: {
        path: join(__dirname, 'dist'),
        filename: 'bundle.js',
        chunkFilename: '[name].bundle.js',
        publicPath: "/dist/",
        devtoolModuleFilenameTemplate: '[absolute-resource-path]'
    },

    resolve: {
        extensions: ['.ts', '.js', '.json', '.css', '.less']
    },

    module: {
        rules: [{
                test: /\.css$/,
                use: extractCSS.extract({
                    fallback: 'style-loader',
                    use: ['css-loader']
                })
            }, {
                test: /\.less$/i,
                use: extractLESS.extract(['css-loader', 'less-loader'])
            },
            {
                test: /\.ts$/,
                loaders: ['ts-loader']
            }             
        ],

    }
}

And in my index.ts file, I reference my less/css file(s):

Index.ts

   import "./css/style.css"
   import "./css/test.less"
