xstate@6.0.0-alpha.15

Patch Changes

• 37d3254: Setup-bound invoke transition callbacks now validate target state context requirements for onDone, onError, onSnapshot, and onTimeout. onDone also infers output from the invoked actor logic.

  import { createAsyncLogic, setup } from 'xstate';
  import { z } from 'zod';
  
  const machine = setup({
    actorSources: {
      loadUser: createAsyncLogic({
        run: async () => ({ name: 'Ada' })
      })
    },
    states: {
      loading: {},
      success: {
        schemas: {
          context: z.object({
            user: z.object({ name: z.string() })
          })
        }
      }
    }
  }).createMachine({
    context: {},
    initial: 'loading',
    states: {
      loading: {
        invoke: {
          src: 'loadUser',
          // Type-safe return value for invoke callbacks
          onDone: ({ event }) => ({
            target: 'success',
            context: { user: event.output }
          })
        }
      },
      success: {}
    }
  });
