I’m new to ember, but if you can use ember-cli instead of the starter kit, this older post should help out a lot: Ember CLI + Express.js - #5 by claudiocro macoto_'s reply to that post (third from the bottom) contains a good link, which has the source code as well from the looks of it.
If you need to migrate to ember-cli there seems to be something to help with that: GitHub - fivetanley/ember-cli-migrator: migrate your files to the standard ember-cli structure, preserving git history I did not personally test this. Please backup everything before this.
And if for some reason you can’t install ember-cli (i.e. ram ~ 512mb), I think digital ocean has a guide for creating a swap file for the install process. Although I think you can just deploy to a server.
Ember-cli is the official scaffolding/building/+ tool to use for projects now.
I hope some of this was helpful
