XState 6.0.0-alpha.49

Minor Changes

• 501c5e3: Add the self-contained xstate/fsm entry point for compact flat finite state machines. It exports createFSM and createFSMActor without including the full statechart actor runtime.

  import { createFSM, createFSMActor } from 'xstate/fsm';
  
  const logic = createFSM({
    initial: 'inactive',
    states: {
      inactive: { on: { toggle: { target: 'active' } } },
      active: { on: { toggle: { target: 'inactive' } } }
    }
  });
  
  const actor = createFSMActor(logic).start();
  

  The FSM runtime also supports guarded transitions, context, actions, eventless transitions, final states, child actors, delayed events, and snapshot persistence for state, context, and self-directed timers. Live inline children and timers targeting other actors are rejected at the persistence boundary because the compact runtime has no registered actor-source registry.
