Extending Controller

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

app/javascript/controllers/color_picker_controller.js
import ColorPicker from "@stimulus-components/color-picker"

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

    // Pickr instance
    this.picker
  }

  // Callback when the color is saved
  onSave(color) {
    super.onSave(color)
  }

  // You can override the components options with this getter.
  // Here are the default options.
  get componentOptions() {
    return {
      preview: true,
      hue: true,

      interaction: {
        input: true,
        clear: true,
        save: true,
      },
    }
  }

  // You can override the swatches with this getter.
  // Here are the default options.
  get swatches() {
    return [
      "#A0AEC0",
      "#F56565",
      "#ED8936",
      "#ECC94B",
      "#48BB78",
      "#38B2AC",
      "#4299E1",
      "#667EEA",
      "#9F7AEA",
      "#ED64A6",
    ]
  }
}

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.
