# useSubscription

Use an RxJS [`Subscription`](https://rxjs.dev/guide/subscription) without worrying about unsubscribing from it or creating memory leaks.

## Usage

<!-- TODO: import rxjs error if enable twoslash -->

```ts no-twoslash
import { useSubscription } from '@vueuse/rxjs';
import { interval } from 'rxjs';

const count = ref(0);

// useSubscription call unsubscribe method before unmount the component
useSubscription(
  interval(1000).subscribe(() => {
    count.value++;
    console.log(count);
  }),
);
```

## Type Declarations

```ts
export declare function useSubscription(subscription: Unsubscribable): void;
```
