How to use Express server with `http2.createSecureServer` for HTTP/2?

[khteh]

Description

I previously used spdy for HTTP/2. However, due to spdy-http2/node-spdy#403 and the repo is inactive, I would like to consider using node native HTTP/2 but there are some caveats. The express app uses a lot of interfaces which work with other third-party libraries like app.use, app.set, app.enable in order to use view engines, setting the views and static artifacts folder, etc. How to achieve this using the http2.createSecureServer? I don't see that in https://nodejs.org/api/http2.html

Minimal Reproduction

import fs from 'fs';
import { app } from './index.js';
import http2 from 'http2';

const options = {
  key: fs.readFileSync('server.key'),
  cert: fs.readFileSync('server.crt')
};

app.set('port', port);
const server = http2.createSecureServer(options, app);

Express doesn't support HTTP/2 yet. There's a bit more information in expressjs/discussions#407 and #5462.
