What are the mapping rules between Angular component and custom element?

The Component properties and logic maps directly into HTML attributes and the browser's event system. Let us describe them in two steps,

  1. The createCustomElement() API parses the component input properties with corresponding attributes for the custom element. For example, component @Input('myInputProp') converted as custom element attribute my-input-prop.
  2. The Component outputs are dispatched as HTML Custom Events, with the name of the custom event matching the output name. For example, component @Output() valueChanged = new EventEmitter() converted as custom element with dispatch event as "valueChanged".
