create-dmg 
Create a good-looking DMG for your macOS app in seconds
Discuss it on Product Hunt and Twitter.
This tool is intentionally opinionated and simple. I'm not interested in adding lots of options.
Install
$ npm install --global create-dmg
Usage
$ create-dmg --help
Usage
$ create-dmg <app>
Example
$ create-dmg 'Lungo.app'
DMG
The DMG requires macOS 10.11 or later and has the filename appName-appVersion.dmg, for example Lungo-1.0.0.dmg.
It will try to code sign the DMG, but the DMG is still created and fine even if the code signing fails, for example if you don't have a developer certificate.
