Compression (i.e. gzip) not working

Technology overview

Fastify web server
- HTTPS enabled (with junk cert/key)
- HTTP/2 enabled
- HTTP/2 push enabled via node-fastify-auto-push
  - "It can be thought as a replacement of the fastify-static plugin that supports automatic server-push."
Webpack for client-side bundling

You'll either wanna trust the cert at server/certs/cert.pem (which is just from node-fastify-auto-push) or generate your own with tls-keygen (per the advice here).
- Trusting certs can be tricky. Refer to tls-keygen#browser-support for some insights for your operating system and browser.

	app.register(
	fastifyAutoPush.staticServe, {
	root: STATIC_DIR,
	prefix: publicPath,
	},
	);

	app.get('/*', (req, reply) => {
	reply.sendFile('index.html') // from STATIC_DIR
	});
