Vue 3 introduces the Composition API, which allows you to use functions and reactivity outside of component instances. To access the current component instance from within a standalone function or outside of the setup() function, you can use the getCurrentInstance() function provided by Vue.
To use getCurrentInstance() and create a reactive proxy of the component instance, you can follow these steps:
1. Import the getCurrentInstance function from the @vue/composition-api package:
```javascript
import { getCurrentInstance } from '@vue/composition-api';
```
2. Call getCurrentInstance() within your function or outside of the setup() function to get the current component instance:
```javascript
const currentInstance = getCurrentInstance();
```
3. Use the currentInstance to access the component instance properties or create a proxy of the instance using the toRefs() function:
```javascript
import { toRefs } from '@vue/composition-api';
const { proxy } = toRefs(currentInstance);
```
Now you can use the proxy object to access and modify the reactive properties of the component instance.
Please note that the Composition API is an optional feature and needs to be installed separately using the @vue/composition-api package.
