@xstate/svelte@6.0.0-alpha.4

Patch Changes

• 5b6df81: xstate is now a required peer dependency of @xstate/react, @xstate/vue, @xstate/svelte, and @xstate/solid. Package managers now warn when xstate is missing instead of letting the adapter fail at runtime.

  useActorRef(), useActor(), and useMachine() in @xstate/react no longer write implementations provided on a later render onto the machine passed on the first render. A module-level machine shared by several components keeps its own implementations:

  const machine = createMachine({
    actions: { notify: () => {} },
    on: { DO: ({ actions }, enq) => enq(actions.notify) }
  });
  
  function Custom({ onNotify }) {
    // Only this component's actor uses `onNotify`.
    useActorRef(machine.provide({ actions: { notify: onNotify } }));
    return null;
  }
  
  function Plain() {
    // Still uses the original `notify`.
    useActorRef(machine);
    return null;
  }
