xstate@5.19.0

Minor Changes

• #4954 8c4b70652acaef2702f32435362e4755679a516d Thanks @davidkpiano! - Added a new transition function that takes an actor logic, a snapshot, and an event, and returns a tuple containing the next snapshot and the actions to execute. This function is a pure function and does not execute the actions itself. It can be used like this:

  import { transition } from 'xstate';
  
  const [nextState, actions] = transition(actorLogic, currentState, event);
  // Execute actions as needed

  Added a new initialTransition function that takes an actor logic and an optional input, and returns a tuple containing the initial snapshot and the actions to execute from the initial transition. This function is also a pure function and does not execute the actions itself. It can be used like this:

  import { initialTransition } from 'xstate';
  
  const [initialState, actions] = initialTransition(actorLogic, input);
  // Execute actions as needed

  These new functions provide a way to separate the calculation of the next snapshot and actions from the execution of those actions, allowing for more control and flexibility in the transition process.
