/**

 * @param {Blob} blob
 * @param {String} fullname
 */
export default function Downloader(blob, fullname) {
  if (typeof window.navigator.msSaveBlob !== 'undefined') {
    // IE workaround for "HTML7007: One or more blob URLs were
    // revoked by closing the blob for which they were created.
    // These URLs will no longer resolve as the data backing
    // the URL has been freed."
    window.navigator.msSaveBlob(blob, fullname);
  } else {
    var blobURL = window.URL.createObjectURL(blob);
    var tempLink = document.createElement('a');

    tempLink.style.display = 'none';
    tempLink.href = blobURL;
    tempLink.setAttribute('download', fullname);

    // Safari thinks _blank anchor are pop ups. We only want to set _blank
    // target if the browser does not support the HTML5 download attribute.
    // This allows you to download files in desktop safari if pop up blocking
    // is enabled.
    if (typeof tempLink.download === 'undefined') {
      tempLink.setAttribute('target', '_blank');
    }

    document.body.appendChild(tempLink);
    tempLink.click();
    document.body.removeChild(tempLink);
    window.URL.revokeObjectURL(blobURL);
  }
}
