Patch Changes

• #3040 18dc2b3e2 Thanks @davidkpiano! - The AnyState and AnyStateMachine types are now available, which can be used to express any state and state machine, respectively:

  import type { AnyState, AnyStateMachine } from 'xstate';
  
  // A function that takes in any state machine
  function visualizeMachine(machine: AnyStateMachine) {
    // (exercise left to reader)
  }
  
  function logState(state: AnyState) {
    // ...
  }

• #3042 e53396f08 Thanks @suerta-git! - Added the AnyStateConfig type, which represents any StateConfig<...>:

  import type { AnyStateConfig } from 'xstate';
  import { State } from 'xstate';
  
  // Retrieving the state config from localStorage
  const stateConfig: AnyStateConfig = JSON.parse(
    localStorage.getItem('app-state')
  );
  
  // Use State.create() to restore state from config object with correct type
  const previousState = State.create(stateConfig);
