import bisectImageToFiles from 'bisect-image-to-files'
const fileInput = document.createElement('input')
fileInput.type = 'file'
fileInput.accept = 'image/*'
fileInput.onchange = async event => {
  const file = event.target.files[0]
  if (file) {
    const files = await bisectImageToFiles(file)
    console.log(files)
  }
