Add the root certificate we just generated to your list of trusted certificates. This step depends on the operating system you're running:

• Mac OS: open Keychain Access, choose System from the left navigation bar, choose "Import items..." from the File app menu and select the file. Then double-click on the certificate and select always-trust in the Trust panel.
• Linux: Depending on your Linux distribution, you can use trust, update-ca-certificates or another command to mark the generated root certificate as trusted.

1. Edit server.js:
   • serve static files with app.use(express.static('<path-to-serve>'))
   • use express as backend, i.e.: app.get('/', (req, res) => res.send('Hello World!'))
2. Install dependency with npm install
3. Run with sudo npm start or sudo node serve.js (root required to use port 443)
