Spinners are used to show merchants that your app is loading, or an action is being performed. Generally when a spinner is being used, the user shouldn't be able to interact.


```ts?title: "JavaScript"

import {extend, Spinner} from '@shopify/admin-ui-extensions';

extend('Playground', (root) => {
  const spinner = root.createComponent(Spinner);
  root.appendChild(spinner);

  setTimeout(() => {
    root.removeChild(spinner);
  }, 2000);

  root.mount();
});


```

```tsx?title: "React"

import React from 'react';
import {extend, render, Spinner} from '@shopify/admin-ui-extensions-react';

function App() {
  return <Spinner />;
}

extend(
  'Playground',
  render(() => <App />),
);


```

| Use Spinner to show that content is loading, or an action is being processed | Don’t place Spinners for each loading element. Rather, Spinners should be at the top level of the section they apply to. |
