    "data" : {
        "file": {
            "url" : "https://www.tesla.com/tesla_theme/assets/img/_vehicle_redesign/roadster_and_semi/roadster/hero.jpg",
            "size": 91,

Fields supported by the UI of block:

• title
• size
• extension (if not present, will be extracted from the name)
• url

Providing custom uploading methods

As mentioned at the Config Params section, you have an ability to provide own custom uploading method. It is a quite simple: implement uploadByFile method and pass them via uploader config param. The method return a Promise that resolves with response in a format that described at the backend response format section.

Example:

import AttachesTool from '@editorjs/attaches';

var editor = EditorJS({
  ...

  tools: {
    ...
    attaches: {
      class: AttachesTool,
      config: {
        /**
         * Custom uploader
         */
        uploader: {
          /**
           * Upload file to the server and return an uploaded image data
           * @param {File} file - file selected from the device or pasted by drag-n-drop
           * @return {Promise.<{success, file: {url}}>}
           */
          uploadByFile(file){
            // your own uploading logic here
            return MyAjax.upload(file).then((response) => {
              return {
                success: 1,
                file: {
                  url: response.fileurl,
                  // any data you want
                  // for example: name, size, title
                }
              };
            });
          },
        }
      }
    }
  }
  ...
});

Providing custom download button event handlers

As mentioned at the Config Params section, you have an ability to provide own custom onClick event handler for the download button. It is a quite simple: implement onClick method and pass them via downloadButton config param. This method will be invoked when the download button is clicked.

Example:

import AttachesTool from '@editorjs/attaches';

var editor = EditorJS({
  ...

  tools: {
    ...
    attaches: {
      class: AttachesTool,
      config: {
        /**
         * Custom download button handler
         */
        downloadButton: {
          /**
           * Custom logic to execute when download button is clicked
           * @param {MouseEvent} event - The click event object
           * @param {Object} data - The file data object, containing information such as url, name, size, extension
           */
          onClick: function(event, data) {
            // Prevent the default download behavior
            event.preventDefault();

            // Custom download logic here
            console.log('File download initiated:', data.file.url);
          }
        }
      }
    }
  }
  ...
});
