const upload = new Upload(context);
const folderRelativeUrl = `/${context.siteUrl.split('/').slice(3).join('/')}/${folderUrl}`;

let progress: ProgressBar = null;
upload
  .addChunked(folderRelativeUrl, filePath, (data) => {
    if (!progress) {
      progress = new ProgressBar(`Uploading ${filePath} [:bar] ${data.fileSize} KB`, { total: data.totalBlocks });
    }
    progress.tick();
