Since we're focusing on writing JavaScript logic in this tutorial, I won't dive into customizing our components. You can find the final markup and styles in my repository. Next, we will concentrate on the part directly related to implementing drag-and-drop functionality.

But where does the data go now? By default, the form data is sent to the URL of the page containing the form — the current page, actually. Generally, all the data should be sent to a server to store and be handled. We can set up a server like Next.js, but it's a big separate topic to discover. You can learn more about it in our tutorial. In this post, I suggest concentrating on uploading staff and using httpbin — a simple OSS HTTP Request & Response Service.
