The other day I had to figure out how to create private NPM packages for plugins, some of them used in Ionic 3/4 projects, hosted using a private Nexus server.

Here are some of the information that ended up learning quite a bit from.

• Use ng-packagr to create a plugin
  • Might be an issue for Ionic
• Scoped NPM packages
• Nexus private registry setup
• How to make Angular libraries like a pro
• Angular Package Format
• Peer dependencies12 in NPM
• semantic-release with CLI vs standard

Modules in Angular

• Feature modules in Angular
  • Use forRoot() to make singleton services from inside modules.
