# Devtools - EventrixDebugger

You can use debugger with [eventrix-devtools](https://github.com/mprzodala/eventrix-devtools) (chrome extension) or only print data in browser console. 

![Eventrix devtools chrome extension](/files/-MdOTaNcgnTVB-gufhIz)

{% tabs %}
{% tab title="Javascript" %}

```javascript
import { Eventrix, EventrixDebugger } from 'eventrix'

const eventrix = new Eventrix({});

const eDebugger = new EventrixDebugger(eventrix);
eDebugger.start();

export default eventrix;
```

{% endtab %}
{% endtabs %}

Now all emitted events and state changes will be saved in debugger. You can print this info in console or use [eventrix-devtools](https://github.com/mprzodala/eventrix-devtools).
