```ts

```

Defined in: [react-pacer/src/async-queuer/useAsyncQueuer.ts:49](https://github.com/TanStack/pacer/blob/main/packages/react-pacer/src/async-queuer/useAsyncQueuer.ts#L49)

Reactive state that will be updated and re-rendered when the queuer state changes

Use this instead of `queuer.store.state`

***

### ~~store~~

```ts
readonly store: Store<Readonly<AsyncQueuerState<TValue>>>;
```

Defined in: [react-pacer/src/async-queuer/useAsyncQueuer.ts:55](https://github.com/TanStack/pacer/blob/main/packages/react-pacer/src/async-queuer/useAsyncQueuer.ts#L55)

#### Deprecated

Use `queuer.state` instead of `queuer.store.state` if you want to read reactive state.
The state on the store object is not reactive, as it has not been wrapped in a `useStore` hook internally.
Although, you can make the state reactive by using the `useStore` in your own usage.

***

### Subscribe()

```ts
Subscribe: <TSelected>(props) => ReactNode | Promise<ReactNode>;
```

Defined in: [react-pacer/src/async-queuer/useAsyncQueuer.ts:40](https://github.com/TanStack/pacer/blob/main/packages/react-pacer/src/async-queuer/useAsyncQueuer.ts#L40)

A React HOC (Higher Order Component) that allows you to subscribe to the queuer state.

This is useful for opting into state re-renders for specific parts of the queuer state
deep in your component tree without needing to pass a selector to the hook.

#### Type Parameters

##### TSelected

`TSelected`

#### Parameters

##### props

###### children

`ReactNode` \| (`state`) => `ReactNode`

###### selector

(`state`) => `TSelected`

#### Returns

`ReactNode` \| `Promise`\<`ReactNode`\>

#### Example

```ts
<queuer.Subscribe selector={(state) => ({ size: state.size, isRunning: state.isRunning })}>
  {({ size, isRunning }) => (
    <div>Queue: {size} items, {isRunning ? 'Processing' : 'Idle'}</div>
  )}
</queuer.Subscribe>
```
