# Spinner

A loading indicator that displays a rotating animation to communicate that content is loading or a background process is in progress.

## Import

```tsx
import { Spinner } from '@coinbase/cds-web/loaders/Spinner'
```

## Examples

### Basics

The `size` prop is required and controls the spinner dimensions. The value is in pixels and determines the font size from which the width (10em), height (10em), and border width (1.1em) are calculated.

```jsx live
<Spinner size={2} />
```

### Buttons

Use `loading` on [Button](/components/inputs/Button) and [IconButton](/components/inputs/IconButton) to show a spinner during async operations. The button becomes non-interactive while preserving its dimensions.

```jsx live
function LoadingButtons() {
  const [isLoading, setIsLoading] = useState(false);

  const handleClick = useCallback(() => {
    setIsLoading(true);
    setTimeout(() => setIsLoading(false), 2000);
  }, []);

  return (
    <HStack gap={2} alignItems="center">
      <Button onClick={handleClick} loading={isLoading}>
        Submit
      </Button>
      <Button onClick={handleClick} loading={isLoading} variant="secondary">
        Save
      </Button>
      <IconButton
        onClick={handleClick}
        loading={isLoading}
        name="refresh"
        accessibilityLabel="Refresh"
      />
    </HStack>
  );
}
```

### Styling

#### Color

Use the `color` prop to customize the spinner's color. The default is `fgMuted`. Any valid CDS design token color can be used.

```jsx live
<HStack gap={3} alignItems="center">
  <Spinner size={3} color="fgMuted" />
  <Spinner size={3} color="fgPrimary" />
  <Spinner size={3} color="fgPositive" />
  <Spinner size={3} color="fgNegative" />
</HStack>
```

##### On Colored Backgrounds

When placing a spinner on a colored background, choose a color with sufficient contrast.

```jsx live
<HStack gap={2}>
  <Box
    background="fgMuted"
    borderRadius={200}
    padding={2}
    display="flex"
    alignItems="center"
    justifyContent="center"
  >
    <Spinner size={3} color="fg" />
  </Box>
  <Box
    background="fgPrimary"
    borderRadius={200}
    padding={2}
    display="flex"
    alignItems="center"
    justifyContent="center"
  >
    <Spinner size={3} color="fg" />
  </Box>
  <Box
    background="fgPositive"
    borderRadius={200}
    padding={2}
    display="flex"
    alignItems="center"
    justifyContent="center"
  >
    <Spinner size={3} color="fg" />
  </Box>
  <Box
    background="fgNegative"
    borderRadius={200}
    padding={2}
    display="flex"
    alignItems="center"
    justifyContent="center"
  >
    <Spinner size={3} color="fg" />
  </Box>
</HStack>
```

#### Sizing

Use different sizes to match the context - smaller spinners work well inline or within buttons, while larger spinners are appropriate for page or section loading states.

```jsx live
<HStack gap={3} alignItems="center">
  <Spinner size={2} />
  <Spinner size={3} />
  <Spinner size={4} />
  <Spinner size={6} />
</HStack>
```

### Accessibility

Use `accessibilityLabel` to provide context for screen readers. The spinner uses `role="status"` and `aria-live="polite"` to announce the loading state.

```jsx live
<Spinner size={3} accessibilityLabel="Loading your account details" />
```

| Prop | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `size` | `number` | Yes | `-` | The font size of the spinner in pixels - used to calculate the width, height, and borderWidth. Width and height are 10em while borderWidth is 1.1em. |
