Package Electron app for local testing

Hi, I’ve just started using Electron to build macOS apps and I’m struggling to find out how to package it up as a proper Mac app so I can test it locally. I’m not worried about distributing it properly just yet.

I started with electron/electron-quick-start as my base and have checked out a few of the packagers/builders but I’m just a bit stuck.

How can I convert it into a .app with a fancy icon and use it as a proper Mac app?

Thank you
