preact-ssr.js
// This file is a slightly modified SSR build from https://github.com/Munawwar/preact-mpa-template
// The added differences are:
// 1. I import 'preact-render-to-string' in the SSR build (this is a bit of additonal bloat for client side code though)
// 2. I do not "externalize" preact either when doing the build. With node.js externalizing was needed to prevent two copies
// of preact being used, as 'preact-render-to-string' pulls it's own node.js copy of preact.
// node_modules/preact/dist/preact.module.js

Looks like my previous approach of keeping the process open is slightly slower than evaluating using --eval flag and allowing the process to exit. This is less messier and shorter code as well.

Output of the above:

<div style="display: flex; max-width: 900px; margin: auto;"><div style="padding: 20px; flex-shrink: 0; display: flex; flex-direction: column; align-items: center; line-height: 1.8em;"><div style="margin-top: 20px; margin-bottom: 10px;"><a href="/"><img src="/public/preact-logo-NGGHNJPX.svg" height="64" width="64" alt="logo" /></a></div><a class="navitem is-active" href="/">Home</a><a class="navitem" href="/about">About</a></div><div id="page-content" style="padding: 20px; padding-bottom: 50px; border-left: 2px solid #eee; min-height: 100vh;"><h1>Welcome</h1>This page is:<ul><li>Rendered to HTML.</li><li>Interactive. <button type="button">Counter 10</button></li></ul></div></div>
