webpack-hot-middleware throws error on HMR update - status.hot is undefined (cannot read property 'status' of undefined)

2.3k Views Asked by At

This is driving me nuts. I'm trying to set up HMR with hapi/hapi-webpack-plugin and webpack-hot-middleware. My set up is an APS.NE MVC 5 application (serving the data) and Aurelia as a front-end framework.

HMR seems to start properly: enter image description here

Then when I make a change on any of my js/html files a rebuild is fired properly, again: enter image description here

but I'm receiving an error in process-update.js where module.hot is undefined and naturally it will error out when it checks for module.hot.status()

enter image description here

Here are the relevant files: webpack-dev-server.js

/* eslint no-console: 0 */
import {Server} from 'hapi';
import H2o2 from 'h2o2';
import yargs from 'yargs';
import Webpack from 'webpack';
import WebpackPlugin from 'hapi-webpack-plugin';
import webpackConfig from './webpack.config.babel';

const argv = yargs.argv;

const isNumeric = n => !isNaN(parseFloat(n)) && isFinite(n);

if (!isNumeric(argv.port)) {
 console.log(`Port must be numeric`);
 process.exit(-1);
}

const compiler = new Webpack(webpackConfig);

const server = new Server();

server.connection({ host: 'localhost', port: 6789, labels: 'proxy-server' });

const assets = {
 publicPath: webpackConfig.output.publicPath,
 hot: false,
 noInfo: true,
 quiet: false,
 host: 'localhost',
 port: 6790,
 stats: {
  colors: true,
 },
};

const hot = {
 log: console.log,
 path: '/__webpack_hmr',
 heartbeat: 10 * 1000,
};

server.register([
  {
   register: H2o2,
  },
  {
   register: WebpackPlugin,
   options: { compiler, assets, hot },
  },
], error => {
 if (error) {
  return console.error(error);
 }

 server.route({
  method: ['GET', 'POST'],
  path: '/{path*}',
  handler: (request, reply) => {
   if (/^Content\/bundles\/[A-Za-z0-9\-]+\.css/.test(request.params.path)) {
    const response = reply('// This is a fake CSS content... :)');
    response.type('text/css');
    return response;
   }

   return reply.proxy({
    host: 'localhost',
    port: argv.port,
    passThrough: true,
   });
  },
 });

 server.start(() => console.log(`Server running on ${server.info.uri}`));
});

Am I missing something in the config that leaves module.hot property undefined?
