## Backend response format

Response of your uploader **should** cover following format:

}
}

## 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](#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:

```js
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
}
};
});
},
}
}
}
}
...
});
```
