Callback services not typed correctly #89
Description
The definitions for InvokeCallback and InvokeCreator are currently:
export type InvokeCallback<
TEvent extends EventObject = AnyEventObject,
TSentEvent extends EventObject = AnyEventObject
> = (
callback: Sender<TSentEvent>,
onReceive: Receiver<TEvent>
) => (() => void) | Promise<any> | void;
export type InvokeCreator<
TContext,
TEvent extends EventObject,
TFinalContext = any
> = (
context: TContext,
event: TEvent,
meta: InvokeMeta
) =>
| PromiseLike<TFinalContext>
| StateMachine<TFinalContext, any, any>
| Subscribable<EventObject>
| InvokeCallback<any, TEvent>;
xstate-codegen narrows the event type down to the event that caused the transition and invoked the service. This makes the event type for the Sender in the InvokeCallback the same. It should be able to send any of the machine's events back to it, regardless of what event caused the service to be invoked.
