HTTPs Server with Node.js and Express

NodeHTTPs1.js

var express = require('express');
var app = express();
var fs = require('fs');

NodeHTTPs2.js

var key = fs.readFileSync('encryption/private.key');
var cert = fs.readFileSync( 'encryption/primary.crt' );
var ca = fs.readFileSync( 'encryption/intermediate.crt' );

NodeHTTPs3.js

var options = {
  key: key,
  cert: cert,
  ca: ca
};

NodeHTTPs4.js

var https = require('https');
https.createServer(options, app).listen(443);

NodeHTTPs5.js

var http = require('http');
http.createServer(app).listen(80);

NodeHTTPs6.js

app.use(function(req, res, next) {
    if (req.secure) {
        next();
    } else {
        res.redirect('https://' + req.headers.host + req.url);
    }
});

Followed these instructions and got this ...

host:web localuser$ ls
apps.js mydomain.csr private.key
host:web localuser$ node apps.js
module.js:529
throw err;
^
Error: Cannot find module 'express'

Which isn't really ideal, running ...

host:web localuser$ uname -r
16.7.0
host:web localuser$ node -v
v8.7.0
host:web localuser$ npm -v
5.4.2

Also did this ..

npm i express -g

• express@4.16.2

"npm i express -g" installs to "global" scope and hence require('express') doesn't work
You need to install express like this:
npm i express

My implementation of this procedure has failed, though a parallel implementation with Nginx succeeded. With Node/Express I get a handshake failure that I have not yet managed to diagnose.
