Browser not refreshing when using the Node API

[peripateticus]

Do you want to request a feature or report a bug? Bug

What is the current behavior?
The code is compiling correctly, however, the browser does not refresh when updating source code. I must manually refresh the browser. I've tried various options with no luck (hot, polling, etc).

When I run using the CLI with the same .conf file, the browser does refresh automatically.

If the current behavior is a bug, please provide the steps to reproduce.

Pretty straightforward code:

Code to start webpack-dev-server

const WDS = require('webpack-dev-server');
const path = require('path');
const webpack = require('webpack');

/**
 * Start webpack dev server.
 */
const wpds = () => {

  const conf = require('./webpack.dev.conf.js');
  const compiler = webpack(conf);
  const port = 8080;
  const cwd = process.cwd();

  const server = new WDS(compiler, {
    port,
    contentBase: path.resolve(cwd, '..', 'dest'),
    publicPath: '/dest/',
  });
  server.listen(port, '127.0.0.1', () => {
    console.log(`Starting server on http://localhost:${port}`);
  });
};


wpds();

webpack.dev.conf.js

const path = require('path');

module.exports = {

  entry: {
    app: path.resolve(__dirname, '../entry.js'),
  },

  output: {
    path: path.resolve(__dirname, '../dest'),
    filename: '[name].bundle.js',
  },

  // I comment out the devServer entry out when running via the node API.
  //devServer: {
  //  contentBase: path.resolve(__dirname, '../dest'),
  //  publicPath: '/dest/',
  //  compress: true,
  //  port: 9000,
  // open: true,
  //  openPage: '',
  //},
};

What is the expected behavior?
Browser updates when source code changes.

If this is a feature request, what is motivation or use case for changing the behavior?

Please mention your webpack and Operating System version.
webpack v3.2.0 (wasn't working in v3.1.0 either)
webpack-dev-server 2.5.1
MacOS Sierra 10.12.5

The solution to this seems to be related to this stack overflow question/answer: https://stackoverflow.com/questions/43747636/live-reloading-in-webpack-dev-server-when-using-node-js-api

and

https://github.com/webpack/webpack-dev-server/blob/master/examples/node-api-simple/webpack.config.js

So, the entry that I used to get this working was:

entry: {
    app: [
      'webpack-dev-server/client?http://localhost:8080',
      path.resolve(__dirname, '../entry.js'),
    ],
  },
