Running an Angular2 app on EC2 - node.js

Question

I'd like to run a basic Angular 2 app on an Ubuntu EC2 instance.
In my case, I installed Angular CLI, and created a new site in /var/www
ng new test
then
ng serve --port 8080
It looks like my basic Angular2 app is running fine

I know port 8080 is open in my security groups, because I just ran a basic Node JS app a few minutes ago in /var/www. When I try to go to http://[Public DNS]:8080, Safari says it can't connect. There's also nothing in my apache logs.

Turns out the real issue is this:

I've tried editing the server.js file and running with the --publicHost option, but those aren't working. I'm using non CLI Angular with the default port 3000 and that's working on EC2 (after adding the security group settings).
