User · Answer

If you need it only locally for local development, I've created utility exactly for this task - https://github.com/pie6k/easy-https

import { createHttpsDevServer } from 'easy-https';

async function start() {
  const server = await createHttpsDevServer(
    async (req, res) => {
      res.statusCode = 200;
      res.write('ok');
      res.end();
    },
    {
      domain: 'my-app.dev',
      port: 3000,
      subdomains: ['test'], // will add support for test.my-app.dev
      openBrowser: true,
    },
  );
}

start();

It:

Will automatically add proper domain entries to /etc/hosts
Will ask you for admin password only if needed on first run / domain change
Will prepare https certificates for given domains
Will trust those certificates on your local machine
Will open the browser on start pointing to your local server https url

Update  Use Let s Encrypt via Greenlock js  Original Post  I noticed that none of these answers show that adding a Intermediate Root CA to the chain  here are some zero-config examples to play with to see that    https   github com solderjs nodejs-ssl-example http   coolaj86 com articles how-to-create-a-csr-for-https-tls-ssl-rsa-pems  https   github com solderjs nodejs-self-signed-certificate-example   Snippet   var options          this is the private key only   key  fs readFileSync path join  certs    my-server key pem        this must be the fullchain  cert   intermediates    cert  fs readFileSync path join  certs    my-server crt pem        this stuff is generally only for peer certificates     ca    fs readFileSync path join  certs    my-root-ca crt pem         requestCert  false     var server   https createServer options   var app   require    my-express-or-connect-app   create server   server on  request   app   server listen 443  function        console log  Listening on     server address   address         server address   port        var insecureServer   http createServer    server listen 80  function        console log  Listening on     server address   address         server address   port         This is one of those things that s often easier if you don t try to do it directly through connect or express  but let the native https module handle it and then use that to serve you connect   express app   Also  if you use server on  request   app  instead of passing the app when creating the server  it gives you the opportunity to pass the server instance to some initializer function that creates the connect   express app  if you want to do websockets over ssl on the same server  for example

The Express API doc spells this out pretty clearly    Additionally this answer gives the steps to create a self-signed certificate   I have added some comments and a snippet from the Node js HTTPS documentation   var express   require  express    var https   require  https    var http   require  http    var fs   require  fs        This line is from the Node js HTTPS documentation  var options       key  fs readFileSync  test fixtures keys agent2-key pem      cert  fs readFileSync  test fixtures keys agent2-cert cert          Create a service  the app object is just a callback   var app   express        Create an HTTP service  http createServer app  listen 80      Create an HTTPS service identical to the HTTP service  https createServer options  app  listen 443

I found following example   https   web archive org web 20120203022122 http   www silassewell com blog 2010 06 03 node-js-https-ssl-server-example    This works for node v0 1 94 - v0 3 1  server setSecure   is removed in newer versions of node   Directly from that source   const crypto   require  crypto      fs   require  fs      http   require  http     var privateKey   fs readFileSync  privatekey pem   toString    var certificate   fs readFileSync  certificate pem   toString     var credentials   crypto createCredentials  key  privateKey  cert  certificate     var handler   function  req  res      res writeHead 200    Content-Type    text plain       res end  Hello World n        var server   http createServer    server setSecure credentials   server addListener  request   handler   server listen 8000

You can use also archive this with the Fastify framework   const   readFileSync     require  fs   const Fastify   require  fastify    const fastify   Fastify     https        key  readFileSync    test asset server key        cert  readFileSync    test asset server cert          logger    level   debug        fastify listen 8080     and run openssl req -nodes -new -x509 -keyout server key -out server cert to create the files if you need to write tests

Found this question while googling  node https  but the example in the accepted answer is very old - taken from the docs of the current  v0 10  version of node  it should look like this   var https   require  https    var fs   require  fs     var options       key  fs readFileSync  test fixtures keys agent2-key pem      cert  fs readFileSync  test fixtures keys agent2-cert pem       https createServer options  function  req  res      res writeHead 200     res end  hello world n       listen 8000

To enable your app to listen for both http and https on ports 80 and 443 respectively  do the following  Create an express app   var express   require  express    var app   express      The app returned by express   is a JavaScript function  It can be be passed to Node   s HTTP servers as a callback to handle requests  This makes it easy to provide both HTTP and HTTPS versions of your app using the same code base   You can do so as follows   var express   require  express    var https   require  https    var http   require  http    var fs   require  fs    var app   express     var options       key  fs readFileSync   path to key pem      cert  fs readFileSync   path to cert pem       http createServer app  listen 80   https createServer options  app  listen 443     For complete detail see the doc

The minimal setup for an HTTPS server in Node js would be something like this    var https   require  https    var fs   require  fs     var httpsOptions         key  fs readFileSync  path to server-key pem        cert  fs readFileSync  path to server-crt pem       var app   function  req  res      res writeHead 200     res end  hello world n       https createServer httpsOptions  app  listen 4433     If you also want to support http requests  you need to make just this small modification    var http   require  http    var https   require  https    var fs   require  fs     var httpsOptions         key  fs readFileSync  path to server-key pem        cert  fs readFileSync  path to server-crt pem       var app   function  req  res      res writeHead 200     res end  hello world n       http createServer app  listen 8888   https createServer httpsOptions  app  listen 4433

The above answers are good but with Express and node this will work fine   Since express create the app for you  I ll skip that here   var express   require  express       fs   require  fs       routes   require    routes     var privateKey   fs readFileSync  cert key pem   toString    var certificate   fs readFileSync  cert certificate pem   toString          To enable HTTPS var app   module exports   express createServer  key  privateKey  cert  certificate
