Node.js — HTTPS

HTTPS Server

const https = require('https');
const fs = require('fs');

const options = {
    key: fs.readFileSync('private-key.pem'),
    cert: fs.readFileSync('certificate.pem')
};

const server = https.createServer(options, (req, res) => {
    res.writeHead(200);
    res.end('Secure Hello!\n');
});

server.listen(443);

Making HTTPS Requests

const https = require('https');

https.get('https://api.example.com/data', (res) => {
    let data = '';
    res.on('data', chunk => data += chunk);
    res.on('end', () => console.log(JSON.parse(data)));
});

SSL Certificates

Type	Description
Self-signed	For development
Let's Encrypt	Free production certs
Commercial	Paid certificates

Self-Signed Certificate

openssl req -x509 -newkey rsa:2048 -nodes -sha256 \
    -subj '/CN=localhost' \
    -keyout localhost-privkey.pem \
    -out localhost-cert.pem

Environment Variables

const options = {
    key: fs.readFileSync(process.env.SSL_KEY),
    cert: fs.readFileSync(process.env.SSL_CERT)
};

Mini Practice

1. Create an HTTPS server
2. Generate self-signed certificates
3. Make HTTPS requests
4. Configure SSL environment
