Handlebars Loader with Webpack 4

I have been looking at examples of how to use the handlebars-loader with webpack but none seem to be working with webpack 4.

Error

ERROR in ./src/templates/property-list-item.hbs Module build failed: TypeError: Cannot read property 'handlebarsLoader' of undefined at getLoaderConfig (/Users/Sam/Desktop/mettamware/Public/js/node_modules/handlebars-loader/index.js:24:37) at Object.module.exports (/Users/Sam/Desktop/mettamware/Public/js/node_modules/handlebars-loader/index.js:32:15) @ ./src/property-list.js 5:0-58 40:23-31 @ ./src/app.js

When I look in node_modeules/handlerbars-loader/index.js, the offending function is this

function getLoaderConfig(loaderContext) {
  var query = loaderUtils.getOptions(loaderContext) || {};
  var configKey = query.config || 'handlebarsLoader';
  var config = loaderContext.options[configKey] || {};
  delete query.config;
  return assign({}, config, query);
}

My webpack.config.js

const path = require('path');

module.exports = {
  entry: './src/app.js',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'bundle.js'
  },
  module: {
    rules: [
      {
        test: /\.hbs$/,
        use: [{
          loader: "handlebars-loader",
          options: {
            helperDirs: path.resolve(__dirname, "./src/helpers")
          }
        }]
      }
    ]
  },
  node: {
    fs: 'empty'
  }
};

If anyone can help I would greatly appreciate it. I've been searching for hours for a solution and have tried lots to things but am not getting anywhere.

In Webpack 4 loaderContext.options has been replaced with loaderContext.rootConfig.

This commit has already been made to the handlebars-loader package to make it compatible with Webpack 4 however this has not been released yet.

For the time being I have uninstalled handlebars-loader and am using this fork.

The following steps have solved my problem:

Run these two commands.
npm uninstall handlebars-loader
npm install @icetee/handlebars-loader

In webpack.config.js, replace

loader: "handlebars-loader"

with

loader: "@icetee/handlebars-loader"
