Minor Changes

• #4806 f4e0ec48c Thanks @davidkpiano! - Inline actor logic is now permitted when named actors are present. Defining inline actors will no longer cause a TypeScript error:

  const machine = setup({
    actors: {
      existingActor: fromPromise(async () => {
        // ...
      })
    }
  }).createMachine({
    invoke: {
      src: fromPromise(async () => {
        // Inline actor
      })
      // ...
    }
  });

Minor Changes

• #4822 f7f1fbbf3 Thanks @davidkpiano! - The clock and logger specified in the options object of createActor(logic, options) will now propagate to all actors created within the same actor system.

  import { setup, log, createActor } from 'xstate';
  
  const childMachine = setup({
    // ...
  }).createMachine({
    // ...
    // Uses custom logger from root actor
    entry: log('something')
  });
  
  const parentMachine = setup({
    // ...
  }).createMachine({
    // ...
    invoke: {
      src: childMachine
    }
  });
  
  const actor = createActor(parentMachine, {
    logger: (...args) => {
      // custom logger for args
    }
  });
  
  actor.start();

  import { createStore } from '@xstate/store';
  
  const store = createStore(
    // initial context
    { count: 0, greeting: 'hello' },

    {
      inc: {
        count: (context) => context.count + 1
      },
      updateBoth: {
        count: () => 42,
        greeting: 'hi'
      }
    }

Minor Changes

• #4746 b570ba20d Thanks @davidkpiano! - The new emit(…) action creator emits events that can be received by listeners. Actors are now event emitters.

  import { emit } from 'xstate';
  
  const machine = createMachine({
    // ...
    on: {
      something: {
        actions: emit({
          type: 'emitted',
          some: 'data'
        })
      }
    }
    // ...
  });
  
  const actor = createActor(machine).start();
  
  actor.on('emitted', (event) => {
    console.log(event);
  });
  
  actor.send({ type: 'something' });
  // logs:
  // {
  //   type: 'emitted',
  //   some: 'data'
  // }
