Answer 1

You could to configure your router to allow in route to your server port.

If you have a fix IP, you don't need more things. If your IP vary along the days, you can to configure your router to use a dynamic IP.

I use https://www.dtdns.com/ , a free dynamic dns provider, to allow an external URL to access my home "server" (a Raspberry PI).

But, already, it starts at configure your router, or, also, using the tunnel listed after, by I believe configuring your modem it's more fast to access (more kb/s) than using tunnel.

Better to have Linux based operating system

1. Write NodeJS app (or download ready one somewhere)
2. Install Nginx - This app will reply and handle all incoming connections
3. Install Phusion Passenger ( Free version ) - This app will make sure your NodeJS application is up and running
4. Copy your application to /var/www/yourappname on Linux and ~/Sites on Mac
5. Configure Phusion Passenger
6. If you have fixed (static) IP-address - you're good to go. Just type your static address and port ( if different from :80 ) into browser
7. If you have dynamic IP-address - You will need a service called Dynamic DNS, I can recommend this one but is is paid service. I'm sure after a bit of Googling you can find a free similar service

If you're doing this - first time, it may looks a bit tricky and can take a day or two. But after few server setups - you will be able to do same operations with closed eyes.
