      ...context,
      position: event.position,
    }),
  },
});

// Create a selector for the position
const position = store.select((context) => context.position);

// Get current value
console.log(position.get()); // { x: 0, y: 0 }

// Subscribe to changes
position.subscribe((position) => {
  console.log('Position updated:', position);
});

// When position updates, only position subscribers are notified
store.trigger.positionUpdated({ position: { x: 100, y: 200 } });
// Logs: Position updated: { x: 100, y: 200 }

</template>
```

--------------------------------

### Create Store Logic with fromStore

Source: https://stately.ai/docs/xstate-store

Demonstrates the basic usage of `fromStore` to define store logic, which is then used to create a store actor via `createActor`. This is a simplified alternative to XState's `createMachine` for less complex state management needs.

```typescript
import { fromStore } from '@xstate/store';

// Instead of:
// const store = createStore({
const storeLogic = fromStore({
  context: {
    // ...
  },
  on: {
    // ...
  },
});

// Create the store (actor)
const storeActor = createActor(storeLogic);
```

    },
  },
}).with(validateSchemas());
```

--------------------------------

### Migrate undoRedo to extension form with .with()

Source: https://stately.ai/docs/xstate-store/migration

The `undoRedo` functionality is now an extension. Use `.with(undoRedo())` when creating the store instead of passing it directly to `createStore`.

```javascript
- const store = createStore(
-   undoRedo({
-     context: { count: 0 },
-     on: {
-       inc: (context) => ({ count: context.count + 1 })
-     }
-   })
- );
+ const store = createStore({
+   context: { count: 0 },
+   on: {
+     inc: (context) => ({ count: context.count + 1 })
+   }
+ }).with(undoRedo());
```

- **store** (object) - A component-scoped XState Store instance.
```

--------------------------------

### Migrate createStore from (context, transitions) to config object

Source: https://stately.ai/docs/xstate-store/migration

The `createStore` API has been updated. Use the config object form with `context` and `on` properties instead of separate context and transitions arguments.

```javascript
- const store = createStore(
-   { count: 0 },
-   {
-     inc: (context) => ({ count: context.count + 1 })
-   }
- );
+ const store = createStore({
+   context: { count: 0 },
+   on: {
+     inc: (context) => ({ count: context.count + 1 })
+   }
+ });
```

--------------------------------

### Selector with Custom Equality Function (X Coordinate)

Source: https://stately.ai/docs/xstate-store

Provide a custom equality function to `store.select()` to control notification triggers. This example only notifies subscribers if the 'x' coordinate changes.

```javascript
const position = store.select(
  (context) => context.position,
  // Only notify if x coordinate changes
  (prev, next) => prev.x === next.x,
);
```

--------------------------------

### Forcing Immediate Storage Write

Source: https://stately.ai/docs/xstate-store/persist

Demonstrates how to force an immediate write to storage using `flushStorage`, typically used before a page unload.

```typescript
import { flushStorage } from '@xstate/store/persist'; 

window.addEventListener('beforeunload', () => {
  flushStorage(store);
});
```

--------------------------------

### Create XState Actor from Store Logic

Source: https://stately.ai/docs/xstate-store

Use `fromStore` to create XState-compatible store logic. This logic can then be passed to `createActor` to instantiate a store actor. This is useful for integrating simple store logic into existing XState applications.

```typescript
import { fromStore } from '@xstate/store';
import { createActor } from 'xstate';

// Instead of:
// const store = createStore( ... };
const storeLogic = fromStore({
  context: { count: 0, incremented: false /* ... */ },
  on: {
    inc: {
      count: (context, event) => context.count + 1,
      // Static values do not need to be wrapped in a function
      incremented: true,
    },
  },
});

const store = createActor(storeLogic);
store.subscribe((snapshot) => {
  console.log(snapshot);
});
store.start();

store.send({
  type: 'inc',
});
```

--------------------------------

### Use Store Logic with Input in React Hook

Source: https://stately.ai/docs/xstate-store

Demonstrates how to use `useStore` hook from `@xstate/store-react` with store logic that requires input for initialization.

```javascript
import { createStoreLogic, useStore } from '@xstate/store-react';

const counterLogic = createStoreLogic({
  context: (input: { initialCount: number }) => ({
    count: input.initialCount,
  }),
  on: {
    inc: (context) => ({
      count: context.count + 1,
    }),
  },
});

function Counter() {
  const store = useStore(counterLogic, { initialCount: 0 });
}
```

--------------------------------

### Provide Input to Store Actor Logic

Source: https://stately.ai/docs/xstate-store

Utilize a context function within `fromStore` to dynamically initialize the actor's context based on provided input. This allows for parameterized store actors, where initial state depends on external values passed during actor creation.

```typescript
import { fromStore } from '@xstate/store';

const storeLogic = fromStore({
  context: (initialCount: number) => ({
    count: initialCount,
  }),
  on: {
    // ...
  },
});

const actor = createActor(storeLogic, {
  input: 42,
});
```

--------------------------------

### Create Store Logic with Input for Context

Source: https://stately.ai/docs/xstate-store

Define store logic where the initial context is determined by an input object. This allows for flexible initialization of store instances.

```javascript
import { createStoreLogic } from '@xstate/store';

const counterLogic = createStoreLogic({
  context: (input: { initialCount: number }) => ({
    count: input.initialCount,
  }),
  on: {
    inc: (context) => ({
      count: context.count + 1,
    }),
  },
});

const store = counterLogic.createStore({ initialCount: 0 });
```

--------------------------------

### Use useStore with Store Logic

Source: https://stately.ai/docs/xstate-store/preact

Creates a component-scoped store instance using createStoreLogic and subscribes to its state with useSelector. The store logic requires an input for initial context.

```javascript
import { createStoreLogic, useSelector, useStore } from '@xstate/store-preact'; 

const counterLogic = createStoreLogic({
  context: (input: { initialCount: number }) => ({
    count: input.initialCount,
  }),
  on: {
    inc: (context) => ({ count: context.count + 1 }),
  },
});

function Counter() {
  const store = useStore(counterLogic, { initialCount: 0 });
  const count = useSelector(store, (state) => state.context.count);

  return <button onClick={() => store.trigger.inc()}>{count}</button>;
}
```

--------------------------------

### Compute Next State from Initial Snapshot

Source: https://stately.ai/docs/xstate-store

Determine the next state and effects from the store's initial state using `store.getInitialSnapshot()` and `store.transition()`.

```javascript
const initialSnapshot = store.getInitialSnapshot();

const [nextState, effects] = store.transition(initialSnapshot, {
  type: 'inc',
  by: 1,
});
```

--------------------------------

### Injecting Store State as Angular Signals

Source: https://stately.ai/docs/xstate-store/angular

Demonstrates how to use `injectStore` to create Angular signals from XState store state. Shows selection of specific properties and custom comparison functions.

```typescript
import { Component } from '@angular/core';
import { injectStore } from '@xstate/store-angular'; 

@Component({
  selector: 'app-counter',
  template: `<div>Count: {{ count() }}</div>`,
})
export class CounterComponent {
  count = injectStore(store, (state) => state.context.count);

  user = injectStore(
    store,
    (state) => state.context.user,
    (prev, next) => prev.id === next.id
  );

  snapshot = injectStore(store);
}
```

--------------------------------

</script>

<div>Count: {$count}</div>
```
```

--------------------------------

### Compute Next State and Effects with store.transition

Source: https://stately.ai/docs/xstate-store

Use `store.transition(state, event)` to compute the next state and effects without changing the store's actual state. Useful for debugging and testing.

```javascript
const store = createStore({
  context: { count: 0 },
  schemas: {
    emitted: {
      incremented: z.object({ by: z.number() }),
    },
  },
  on: {
    inc: (context, event: { by: number }, enqueue) => {
      enqueue.emit.incremented({ by: event.by });

      enqueue.effect(() => {
        setTimeout(() => {
          console.log('incremented');
        }, 1000);
      });

      return {
        ...context,
        count: context.count + event.by,
      };
    },
  },
});

const snapshot = store.getSnapshot();

const [nextState, effects] = store.transition(snapshot, {
  type: 'inc',
  by: 1,
});

console.log(nextState.context);
// => { count: 1 }

console.log(effects);
// => [
//   { type: 'incremented', by: 1 },
//   Function
// ]

// The store's state is unchanged
console.log(store.getSnapshot().context);
// => { count: 0 }
```

--------------------------------

### Migrate createStoreWithProducer to createStore with Immer

Source: https://stately.ai/docs/xstate-store/migration

The `createStoreWithProducer` API is removed. Use the `createStore` API and call your producer (e.g., Immer's `produce`) inside transition handlers. When using Immer, return `undefined` from the transition before calling `produce(...)` if the event should not result in a transition.

```javascript
- import { createStoreWithProducer } from '@xstate/store';
+ import { createStore } from '@xstate/store';
  import { produce } from 'immer';

- const store = createStoreWithProducer(produce, {
+ const store = createStore({
    context: { count: 0 },
    on: {
-     inc: (context) => {
-       context.count++;
-     }
+     inc: (context) =>
+       produce(context, (draft) => {
+         draft.count++;
+       })
    }
  });
```

--------------------------------

### Use useStore to create a component-scoped XState Store in Svelte

Source: https://stately.ai/docs/xstate-store/svelte

  } from '@xstate/store-svelte';

  const counterLogic = createStoreLogic({
    context: (input: { initialCount: number }) => ({
      count: input.initialCount,
    }),
    on: {
      inc: (context) => ({ count: context.count + 1 }),
    },
  });

  const store = useStore(counterLogic, { initialCount: 0 });
  const count = useSelector(store, (state) => state.context.count);
</script>

<button on:click={() => store.trigger.inc()}>{$count}</button>
```

--------------------------------

### Update import path for framework packages

Source: https://stately.ai/docs/xstate-store/migration

```javascript
- import { useSelector } from '@xstate/store/react';
+ import { useSelector } from '@xstate/store-react';
```

--------------------------------
