The interesting project although it might end up with quite complicated API to cover all cases that XState supports.

As for unions, usually, I do the following when it's hard to have correctly typed one end. It will correctly type-check like that without the need for verbose enum.

export const makeEvent = (name: TLightSwitchEvent) => name

// in the component

send(makeEvent('TOGGLE'))

Not sure why send is not currently typed in this regard. It should ideally be able to infer from the machine itself.

And matches are obvious bigger nut to crack with nesting. I am not sure if TS allows for it dynamically.
