πŸŽ› Extending Controller

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

import ScrollTo from 'stimulus-scroll-to'

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

  // You can set default options in this getter for all your anchors.
  get defaultOptions() {
    return {
      offset: 100,
      behavior: 'auto',
    }
  }
}

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.

Compatibility

The Window.scrollTo() method is used under the hood.

It's basically compatible with every modern browsers. For now, Safari does not provide smooth behavior scroll support.

See https://caniuse.com/mdn-api_scrolltooptions_behavior.

You can easily add it with this polyfill: smoothscroll-polyfill.
