Nodejs basic auth with https - node.js

Question

I have a nodjs app running that uses basic auth with the password details in a file generated by htpasswd. This is working fine.
What I'd like to do is run it over https. I can get it working with https fine, but can't seem to work out how to get the two working together, https + basic auth.
This is for a browser going to the server and sending a variable in the url. I've found a few solutions but many seem to focus on the server doing a outbound call to something else with basic auth.
This is the basic auth one.
// Authentication module.
const auth = require('http-auth');
const basic = auth.basic({
realm: "REALM.",
file: __dirname + "/users.htpasswd"
});
const http = require('http');
const fs = require('fs');
var url = require('url');
const hostname = '0.0.0.0';
const port = 80;
const server = http.createServer(basic, (req, res) => {
var url_parts = url.parse(req.url, true);
var key = url_parts.query["name"];
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
fs.readFile(__dirname + '/basic.json', function (err, data) {
if (err) {
throw err;
}
table = JSON.parse(data.toString());
var value = table[key];
res.end(JSON.stringify({"group" : value}));
});
});
server.listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
});
And this is the https bit without the basic auth.
const https = require('https');
const fs = require('fs');
var url = require('url');
const hostname = '0.0.0.0';
const port = 443;
const options = {
key: fs.readFileSync('star.pkey'),
cert: fs.readFileSync('star.pem'),
};
const server = https.createServer(options, (req, res) => {
var url_parts = url.parse(req.url, true);
var key = url_parts.query["name"];
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
fs.readFile(__dirname + '/basic.json', function (err, data) {
if (err) {
throw err;
}
table = JSON.parse(data.toString());
var value = table[key];
res.end(JSON.stringify({"group" : value}));
});
});
server.listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
});
Any help appreciated.
