How to auto refresh browser with webpack on change?

I have a this file backend-dev.js which is mostly webpack configuration. I use it to run my express server from the bundled file. It stays on and restarts the server on any change. Is there any possible configuration can be added to auto refresh the browser too whenever I change the code? This is what I have in the backend-dev.js:

const path = require('path');
const webpack = require('webpack');
const spawn = require('child_process').spawn;
const HtmlWebpackPlugin = require('html-webpack-plugin');

const compiler = webpack({
    // add your webpack configuration here
    entry: './app.js',
    output: {
      path: path.resolve(__dirname, 'dist'),
      filename: "bundle.js"
    },
    module: {
      rules: [
        {
          test: /\.js$/,
          exclude: /node_modules/,
          use: {
            loader: 'babel-loader',
            options: {
              presets: ['env', 'es2015', 'stage-2']
            }
          }
        }
      ]
    },
    /*plugins: [
      new HtmlWebpackPlugin({
            title: 'Project Demo',
            hash: true,
            template: './views/index.ejs' // Load a custom template (ejs by default see the FAQ for details)
      })
    ],*/
    node: {
        __dirname: false
    },
    target: 'node'
});

const watchConfig = {
    // compiler watch configuration
    // see https://webpack.js.org/configuration/watch/
    aggregateTimeout: 300,
    poll: 1000
};

let serverControl;

compiler.watch(watchConfig, (err, stats) => {
    if (err) {
        console.error(err.stack || err);
        if (err.details) {
            console.error(err.details);
        }
        return;
    }

    const info = stats.toJson();

    if (stats.hasErrors()) {
        info.errors.forEach(message => console.log(message));
        return;
    }

    if (stats.hasWarnings()) {
        info.warnings.forEach(message => console.log(message));
    }

    if (serverControl) {
        serverControl.kill();
    }

    // change filename to the relative path to the bundle created by webpack, if necessary(choose what to run)
    serverControl = spawn('node', [path.resolve(__dirname, 'dist/bundle.js')]);

    serverControl.stdout.on('data', data => console.log(data.toString()));
    serverControl.stderr.on('data', data => console.error(data.toString()));
});
