Extending Controller

You can use inheritance to extend the functionality of any Stimulus component:

app/javascript/controllers/reveal_controller.js
import Reveal from "@stimulus-components/reveal"

export default class extends Reveal {
  connect() {
    super.connect()
    console.log("Do what you want here.")
  }
}

This controller will automatically have access to targets defined in the parent class.

If you override the connect, disconnect or any other methods from the parent, you'll want to call super.method() to make sure the parent functionality is executed.
