Installed Discourse on subdomain via DigitalOcean Droplet. How do I add node/Vue.js on main domain?

Thanks Jay,
I guess my question is more on the DigitalOcean side. Seemed like a lot of Discourse users went the same route I did (Following github tutorial to setup Discourse on $5 DO Droplet on a subdomain).

Just can’t find any good tutorials out there on after a user installs on a subdomain, let’s now setup a node/git repo workflow on the main domain.

Discourse led me to DigitalOcean, so not really experienced with either of these technologies yet.
I’ll keep digging. :wink:
