# Additional debugging information

To get better understanding on what is changing what `react-state-rxjs` supports state `messages` or `actionType`. In order to set additional debugging information you need to pass an object as a third parameter to `store.update` method.

```typescript
 addTodo(item: TodoModel) {
    this.store.update(state => {
        state.push(fromJS(item));
    }, false, { message: "Item Added" })
}
```

Complete message would look like:

{% hint style="info" %}
'${statePath} - {message || actionType}'
{% endhint %}
