# useProxySlot

useProxySlot allows you to observe the nodes assigned to a slot and reassign them to another slot dynamically, example:

**Input**: Suppose we have a component that observe the slot\[name="slide"] node

```html
<my-component>
    <img slot="slide" src="slide-1"/>
    <img slot="slide" src="slide-1"/>
    <img slot="slide" src="slide-1"/>
</my-component>
```

**output**: thanks to useProxySlot you will be able to modify the assignment of the list nodes without losing the nodes in the process as normally happens with useSlot, example:

```html
<my-component>
    <img slot="slide-1" src="slide-1"/>
    <img slot="slide-2" src="slide-1"/>
    <img slot="slide-3" src="slide-1"/>
</my-component>
```

### Syntax and example

```jsx
import { useRef } from "atomico";
import { useProxySlot } from "@atomico/hooks/use-slot";

function component() {
  const ref = useRef();
  const children = useProxySlot(ref);

  return (
    <host shadowDom>
      <slot name="slide" ref={ref} />
      {children.map((child, index) => (
        <slot name={(child.slot = "slide-" + index)} />
      ))}
    </host>
  );
}
```

{% hint style="info" %}
All redirected hooks must exist under a slot
