Nested Uploads

When supplised with a fullPath key, nested uploads will retain their paths on upload:

  // File Uploads
  try {
    // https://docs.dropzone.dev/configuration/basics/configuration-options
    Dropzone.options.fileupload = {
      paramName: 'file',
      withCredentials: true,
      init: function init() {
        // Allow dropping a folder to upload all files.
        this.hiddenFileInput.setAttribute('webkitdirectory', true);
      },
    };

    const dropzone = new Dropzone('.dropzone');

    // Add more information to the file uploads.
    dropzone.on('sending', (file, _xhr, formData) => {
      formData.append('fullPath', file.fullPath || '');
      formData.append('filesize', file.size || 0);
      formData.append('lastModified', file.lastModified || Date.now());
    });

    // Read the upload path from the elements data-upload attribute and escape any text sent back from the server.
    dropzone.on('success', (file, responseText) => {
      // Create the correct type of Markdown link.
      let linkToUploadedFile = `[${file.name}](${encodeURI(responseText)})`;
      if (file.type.startsWith('image/')) {
        linkToUploadedFile = `![${file.name}](${encodeURI(responseText)})`;
      } else if (file.type.startsWith('video/')) {
        linkToUploadedFile = `<video controls playsinline muted src="${responseText}"></video>`;
      }

      // Copy to clipboard.
      navigator.clipboard.writeText(linkToUploadedFile).then(() => {
        console.log('Async: Copying to clipboard was successful!');
      }, (error) => {
        console.error('Async: Could not copy text: ', error);
      });

      // Append to the content.
      /** @type {HTMLTextAreaElement | null} */
      const textarea = document.querySelector('textarea#editing');
      if (textarea) {
        textarea.value = `${textarea.value}\n${linkToUploadedFile}\n`;
        textarea.dispatchEvent(new Event('input'));
      }
    });
  } catch (error) {
    console.error('Dropzone Error:', error);
  }
