Sometimes you need to get access to the underlying DOM element and use the browser APIs directly.

To get from a visual Noodl node to a DOM element we'll connect a visual node to a Script node. The input type should be `"reference"` (or `"*"` to accept all types). This example uses a Group, but any visual node will work.

```js
Script.Inputs = {
    group: 'reference',
}
```

Once we have the reference to a Noodl node we can get the DOM element reference with `getDOMElement()` on the Noodl node.

A visual node might be unmonted, or haven't had a chance to render yet. To make sure there's a DOM element we'll use the **Did Mount** output from the Noodl node. This makes sure we'll get the latest DOM reference, and that our code won't run until the visual node is actually rendered.

```js
Script.Inputs = {
    group: 'reference',
}

Script.Signals = {
    didMount() {
        const domElement = Script.Inputs.group.getDOMElement()
        //domElement.addEventListener(...)
    },
    willUnmount() {
        // const domElement = Script.Inputs.group.getDOMElement();
        // domElement.removeEventListener(...)
    },
}
```
