Source

This function is useful for executing transition logic and resolving the resulting state in a state machine. It supports both direct state transitions and transition handlers for flexible state management.

export function resolveExitState<FC extends FactoryMachineContext<any>>(
  transition: FactoryMachineTransition<FC["states"]> | undefined,
  ev: ResolveEvent<FactoryMachineEvent<FC>>,
  states: FC["states"]
) {
  if (!transition) {
    return undefined;
  }

  if (typeof transition === "function") {
    const stateOrFn = transition(...ev.params);
    return typeof stateOrFn === "function" ? (stateOrFn as any)(ev) : stateOrFn;
  }

  return states[transition as keyof typeof states](...ev.params) as any;
}
