import { useHover } from 'stimulus-use'

export default class extends Controller {
  
  connect() {
    useHover(this, { element: this.element });
  }
  
  mouseEnter() {
    // ...
    this.element.classList.add('active')
  }

  mouseLeave() {
    // ...
    this.element.classList.remove('active')
  }
}
