* `ViewModel class reference`
* [`React`](https://react.dev) component created with [`withViewModel()`](/react/api/with-view-model)
* Anchor component registered via [config `anchors`](/react/api/with-view-model#anchors) or method [`connect()`](/react/api/with-view-model#connectanchor)

```ts
import { ViewModelStoreBase, ViewModelBase } from "mobx-view-model"

const vmStore = new ViewModelStoreBase();


class MyVM extends ViewModelBase {
  constructor() {
    super({ id: '1', payload: {} });
  }
}

const vm = new MyVM();
...
await vmStore.attach(vm) // this is required thing
...
vmStore.get(vm.id) // instance of MyVM
...
```
