Answer 1

Our straightforward, switchable implementation:

const app = require('express')();
const https = require('https');
const http = require('http');
const next = require('next');
const fs = require('fs');
const path = require('path');

const HTTPS = true;
const server = HTTPS
  ? https.createServer(
      {
        key: fs.readFileSync(path.resolve(__dirname, './server.key')),
        cert: fs.readFileSync(path.resolve(__dirname, './server.cert')),
      },
      app
    )
  : http.createServer({}, app);

const port = parseInt(process.env.PORT, 10) || 3000;
const dev = process.env.NODE_ENV !== 'production';
const nextApp = next({ dev });
const nextHandler = nextApp.getRequestHandler();

nextApp.prepare().then(() => {
  app.get('/api/something', (req, res) => {
    res.json({});
  });

  // ...

  app.get('*', (req, res) => {
    return nextHandler(req, res);
  });

  server.listen(port, (err) => {
    if (err) throw err;
    console.log(`> Ready on http${HTTPS ? 's' : ''}://localhost:${port}`);
  });
});
