This is the Cumulocity module federation plugin. Plugins can be developed like any Cumulocity application, but can be used at runtime by other applications. Therefore, they export an Angular module which can then be imported by any other application. The exports are defined in package.json:

"exports": [
  {
     "name": "Example widget plugin",
     "module": "WidgetPluginModule",
     "path": "./widget/widget-plugin.module.ts",
     "description": "Adds custom widget"
  }
]

How to start Run the command below to scaffold a widget plugin.

c8ycli new <yourPluginName> widget-plugin

As the app.module is a typical Cumuloctiy application, any new plugin can be tested via the CLI:

npm start -- --shell cockpit

In the Module Federation terminology, widget plugin is called remote and the cokpit is called shell. Modules provided by this widget will be loaded by the cockpit application at the runtime. This plugin provides a basic custom widget that can be accessed through the Add widget menu.

Note that the --shell flag creates a proxy to the cockpit application and provides WidgetPluginModule as an remote via URL options.

Also deploying needs no special handling and can be simply done via npm run deploy. As soon as the application has exports it will be uploaded as a plugin.
