rpclibrary offers a special type of call that can be used with callbacks. The callback **has to be the last argument** and **may be the only passed function**.

The uuid, as the name implies, is used to uniquely identify the callback for a given invocation and also dictates the name given to the client-side RPC. Unless you got a preferred way of generating these (e.g. using some kind of unique information important to your task) we recommend [uuid](https://www.npmjs.com/package/uuid) for this purpose.
