Please make sure that in every time we mention source we mean it only for the server side of the callbacks only.

lib.promise.on

name: Name of the server callback to define.
func: Function to execute when callback is triggered (always receives source as first parameter).

return: boolean, if the callbacks successfuly defined will return true, if not it will return false.

debug: (default: false)
- Enable debug logging for this callback.
- Debug mode logs callback's triggers, returns, and timeouts that went during that callback's trip.
timeout: (default: 10000)
- How much time in milliseconds to await for the client side before timing-out the callback and breaking it.
- You can ignore it to use the default time.
name:
- Name of the registered client callback to await for.
source: (server only)
- The client player server's ID to await from.
...varargs :
- Additional arguments to pass to the callback.

⚠️

All registered callbacks are not unique identifiers for the callback, you need to pass the resource name and the side.
e.g lib.promise.on('getData'). instead you need to define it like this: lib.promise.on('tr_kit:server:getData'). the callbacks are designed to be global and any one else can call them.

Runtime errors are caught and logged automatically.
Automatically handles nil returns and multiple return values.
Awaiting from the js will not block the runtime, you need to use the native await attr and synchronousing the function you are in.
