How to add https security for Node js

Question

I am writing a chaincode and I want all the services in this to be https secure. I have followed https://www.linuxhelp.com/how-to-install-and-update-openssl-on-ubuntu-16-04/ to generate certificate and private key. Now I have this following code and I want to know how to add https security.

#!/usr/bin/env node

var app = require('../app');

var fs = require('fs');

var http = require('http');

var https = require('https');

require("dotenv").config();

var privateKey = fs.readFileSync('key.pem').toString();

var certificate = fs.readFileSync('cert.pem').toString();

var port = normalizePort(process.env.PORT || '8080');

app.set('port', port);

var hostname = process.env.HOSTNAME;

function normalizePort(val) {

  var port = parseInt(val, 10);

  if (isNaN(port)) {

    // named pipe

    return val;

  }

  if (port >= 0) {

    // port number

    return port;

  }

  return false;

}

https.createServer(function (req, res) {

  res.writeHead(200, {'Content-Type': 'text/plain'});

  res.write('Hello World!');

  res.end();

}).listen(8080);

Answer 1

You need to add the key and cert to the createServer function.

const options = {

    key: fs.readFileSync('key.pem').toString();

    cert: fs.readFileSync('cert.pem').toString();

}

https

.createServer(options, function (req, res) {

  res.writeHead(200);

  res.end("hello world\n");

})

.listen(443, function(){

    console.log("Server listening on localhost:443");

});

This will make your services https secure.
