export default class MyPlugin extends LitElement {
    fistUpdated() {
        this.getRootNode().addEventListener('oscd-event', () => { ... });
    }

}

In the code example above, the plugin listens to an OscdEvent dispatched by (for example) another plugin and is listening to this event via the common parent; Open-SCD Core.

• Body
  • OpenSCD
    • Menu Plugin 1
    • Menu Plugin 2
    • Active Editor Plugin

Due to WebApi restrictions, Events that are emitted by one of the plugins are only bubbling up directly (https://www.freecodecamp.org/news/event-bubbling-in-javascript/)Find a (seperate solution) for all problems mentioned.

Pro's:

No new Code needs to be introduced

Con's:

This is only working for HTMLElements (Plugins).

Consequences

Implementing a central event-bus means that current OSCD plugins need some refactoring to dispatch events to the event-bus instead of dispatching events on itself.
