Minor Changes

• #4082 13480c3a9 Thanks @davidkpiano! - You can now inspect actor system updates using the inspect option in createActor(logic, { inspect }). The types of inspection events you can observe include:

  • @xstate.actor - An actor ref has been created in the system
  • @xstate.event - An event was sent from a source actor ref to a target actor ref in the system
  • @xstate.snapshot - An actor ref emitted a snapshot due to a received event

  import { createMachine } from 'xstate';
  
  const machine = createMachine({
    // ...
  });
  
  const actor = createActor(machine, {
    inspect: (inspectionEvent) => {
      if (inspectionEvent.type === '@xstate.actor') {
        console.log(inspectionEvent.actorRef);
      }
  
      if (inspectionEvent.type === '@xstate.event') {
        console.log(inspectionEvent.sourceRef);
        console.log(inspectionEvent.targetRef);
        console.log(inspectionEvent.event);
      }
  
      if (inspectionEvent.type === '@xstate.snapshot') {
        console.log(inspectionEvent.actorRef);
        console.log(inspectionEvent.event);
        console.log(inspectionEvent.snapshot);
      }
    }
  });

Patch Changes

• #4336 17da18692 Thanks @Andarist! - Invoked actors will no longer be automatically started (added to .children) when those children are missing in the persisted state.
