Edit
package.json to include a scripts section:

"js-flags": "--expose-gc",
"window": {
"title": "",
"toolbar": false,
"width": 816,
"height": 624,
"icon": "icon/icon.png"
},
"scripts": {
"start": "http-server -c-1 -p 8081 --cors"
},
"dependencies": {
"http-server": "^0.12.3"
}
}
Back in Terminal:
npm start
Open the resultant address reported e.g.
You must be registered to see the links
and play the bestest weirdest sexiest game ever!
