The story so far... We already have our Nuxt application up and running on a Windows 2019 server, and we have IIS configured as a reverse proxy. So when you go to http://example.com/nuxtApp - the correct page is served. Awesome.
So "all" there is left to do is get Node running in the background. Enter PM2:
We're going to attempt to drive this using pm2-installer
Note you'll need to run these commands as a windows administrator
And that really was all it took :)
