v4-without-jquery EventHandler?

Created by: ghost

v4-without-jquery has a Modal class.

How do I go about listening to events? E.g. show, hide, etc.

From looking at the source code, it seems I need to access EventHandler. It is not exported. Should it be exported? I went ahead and added it to index.js, and recompiled:

import Alert from './alert'
import Button from './button'
import Carousel from './carousel'
import Collapse from './collapse'
import Dropdown from './dropdown'
import Modal from './modal'
import Popover from './popover'
import ScrollSpy from './scrollspy'
import Tab from './tab'
import Toast from './toast'
import Tooltip from './tooltip'
import Util from './util'
import EventHandler from './dom/eventHandler'

/**
 * --------------------------------------------------------------------------
 * Bootstrap (v4.2.1): index.js
 * Licensed under MIT (https://github.com/twbs/bootstrap/blob/master/LICENSE)
 * --------------------------------------------------------------------------
 */

export {
  Util,
  Alert,
  Button,
  Carousel,
  Collapse,
  Dropdown,
  Modal,
  Popover,
  ScrollSpy,
  Tab,
  Toast,
  Tooltip,
  EventHandler
}

Not sure if this is the correct approach?
