webpack3 jshint-loader does not work

Question

I'm trying to follow this instruction https://webpack.js.org/loaders/jshint-loader/ and get an error:

My config file:

error text:

Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema. - configuration has an unknown property 'jshint'. These properties are valid: object { amd?, bail?, cache?, context?, dependencies?, devServer?, devtool?, entry, externals?, loader?, module?, name?, node?, output?, performance?, plugins?, prof ile?, recordsInputPath?, recordsOutputPath?, recordsPath?, resolve?, resolveLoader?, stats?, target?, watch?, watchOptions? } For typos: please correct them. For loader options: webpack 2 no longer allows custom properties in configuration.

The instructions on their website seem to be outdated as this isn't working indeed. There's an open issue about this on Github.

This configuration should work:

const path = require('path');

module.exports = {
  entry: {
    app: './index.js'
  },
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist')
  },

  module: {
    rules: [{
      test: /\.js$/, // include .js files
      enforce: "pre", // preload the jshint loader
      exclude: /node_modules/, // exclude any and all files in the node_modules folder
      use: [{
        loader: "jshint-loader",
        // more options in the optional jshint object
        options: {  // ⬅ formally jshint property
          camelcase: true,
          emitErrors: false,
          failOnHint: false
        }
      }]
    }]
  },
};
