Build won't run with Laravel Mix and hot module reload enabled

[alexpcoleman]

Issue description or question

The build just won't run when using Mix w/ HMR. My guess is that the clean somehow confusing the hot build.

Webpack Config

require('dotenv').config()

let mix = require('laravel-mix')
	.setPublicPath('build/dist')
	.setResourceRoot('/dist');

const webpack = require('webpack')
const { CleanWebpackPlugin } = require('clean-webpack-plugin');

/**
 * Settings.
 */

mix.webpackConfig({
	plugins: [
		// Ignore all locale moment.js files, except for the en one.
		// https://stackoverflow.com/a/25426019
		new webpack.ContextReplacementPlugin(/moment[\/\\]locale$/, /en/),
    ],
    module: {
		// ...
	},
	resolve: {
		// ...
	},
});


// Enable source maps & set hot reload URL for development.
if ( ! mix.inProduction())
{
	mix.sourceMaps()

	mix.webpackConfig({
		devServer: {
			sockHost: 'sm-craft-hot.test',
			sockPort: 443
		},
		plugins: [
			new CleanWebpackPlugin(),
		],
	})

	mix.options({
		hmrOptions: {
			host: 'sm-craft-hot.test',
			port: 443
		},
		processCssUrls: false
	})
}

/**
 * Commands.
 */

// Main Vue app w/ dashboard theme.
mix.js([
	'resources/js/app.js',
	'resources/js/dashboard/theme/main.js',
], 'app.js');

// Dashboard styles.
mix.sass('resources/sass/dashboard/dashboard.scss', 'dashboard.css')
