  let target = document.querySelector(elem)
  const config = {
    attributes: true // this is to watch for attribute changes.
  }

  function template(data) {

    `
  }

  // create an observer instance
  var observer = new MutationObserver(function (mutation) {
    
    console.log('mutation', mutation)

    // template(mutation)
  })

  observer.observe(target, config)
})();
