What's the replacement for webpack-dev-server in Webpack 4? : <p>I've noticed that installing <code>webpack-dev-server@webpack/webpack#next</code> actually installs webpack (without any warning). However, there's no <code>webpack-dev-server</code> executable any more.</p>

<p>Is there a replacement for this in Webpack 4, or do I need a separate web server?</p>

<p>It was really convenient to quickly spin up a web server with hot reloading. What's the recommended way to do that in Webpack 4?</p>

<p>(Why I'm bothering with Webpack 4 at all? Because it supports native .mjs modules)</p>
