Backend response format

This Tool works by following scheme:

1. User select file from the device
2. Tool sends it to your backend
3. Your backend should save file and return file data with JSON at specified format.
4. Image tool shows saved image and stores server answer

So, you can implement backend for file saving by your own way. It is a specific and trivial task depending on your environment and stack.

Response of your uploader should cover following format:

{
    "success" : 1,
    "file": {
        "url" : "https://www.tesla.com/tesla_theme/assets/img/_vehicle_redesign/roadster_and_semi/roadster/hero.jpg",
        // ... and any additional fields you want
    }
}

success - uploading status. 1 for successful, 0 for failed

file - uploaded file data. Must contain an url field with full public path to the uploaded image. Also, can contain any additional fields you want to store. For example, width, height, id etc. All additional fields will be saved at the file object of output data.
