Fast solution to replace the node-spdy package using with the express.js on the node v12. Development purposes only!

instructions.txt

1. npm uninstall spdy
2. npm install http2-proxy finalhandler
3. replace the code

import spdy from 'spdy';

spdy.createServer(HTTP2_OPTIONS, app).listen(HTTP2_PORT, (error) => { ... 

with

import proxy from 'http2-proxy';
import finalhandler from 'finalhandler';

const defaultWebHandler = (err, req, res) => {
  if (err) {
    console.error('proxy error', err);
    finalhandler(req, res)(err);
  }
};

/** optional code, requires import os from 'os'; */
const addresses = [];
const interfaces = os.networkInterfaces();
for (const k in interfaces) {
  for (const k2 in interfaces[k]) {
    const address = interfaces[k][k2];
    if (address.family === 'IPv4' && !address.internal) {
      addresses.push(address.address);
    }
  }
}

const expressServer = http.createServer(app);
expressServer.listen(0, (error) => {
  if (error) {
    console.error(error);
    return process.exit(1);
  }

  const { port } = expressServer.address();
  console.log(`Serving http/1.1 server on http://localhost:${ port }`);
  console.log(`Serving http/1.1 server on http://${ addresses[0] }:${ port }`, '\n');

  const http2server = http2.createSecureServer({ ...HTTP2_OPTIONS, allowHTTP1: true });

  http2server.on('request', (req, res) => {
    proxy.web(req, res, {
      hostname: 'localhost',
      port,
      onReq: (_req, { headers }) => {
        if (_req.headers.host) {
          headers['x-forwarded-for'] = _req.socket.remoteAddress;
          headers['x-forwarded-proto'] = _req.socket.encrypted ? 'https' : 'http';
          headers['x-forwarded-host'] = _req.headers.host;
        }
      },
    }, defaultWebHandler);
  });

  http2server.listen(HTTP2_PORT, void 0, (http2error) => {
    if (http2error) {
      console.error(http2error);
      return process.exit(1);
    }
    console.log('Serve http/2 server on https://localhost');
    console.log(`Serve http/2 server on https://${ addresses[0] }`, '\n');
    console.log('Don\'t forget to allow insecure localhost chrome://flags/#allow-insecure-localhost');
    console.log('Mac OS trust instructions http://www.robpeck.com/2010/10/google-chrome-mac-os-x-and-self-signed-ssl-certificates/#.XD7yJM8zaDc', '\n');
    return true;
  });

  return true;
});
