    "file": {

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.

Method	Arguments	Return value	Description
uploadByFile	File	{Promise.<{success, file: {url}}>}	Upload file to the server and return an uploaded file data

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
                }
              };
            });
          },
        }
      }
    }
  }
