## reactivelyReactivityAdapter (`default`)

```js
import { reactive } from '@reactively/core'
import { Collection } from '@signaldb/core'
import reactivelyReactivityAdapter from '@signaldb/reactively'

const posts = new Collection({
  reactivity: reactivelyReactivityAdapter,
})

reactive(() => {
  console.log(posts.find({ author: 'John' }).count())
})
```

Reactivity adapter for usage with [@reactively/core](https://github.com/modderme123/reactively).

The API of Reactively doesn't allow [reactive scope checking](/reactivity/#reactivity-libraries).
You must manually disable reactivity when making calls outside a reactive scope to avoid memory leaks. You can do this by passing `{ reactive: false }` to your options (e.g. `<collection>.find({ ... }, { reactive: false })`).
