> enforce specific casing for slot names

## :book: Rule Details

This rule enforces proper casing of slot names in Vue components.

<eslint-code-block :rules="{'vue/slot-name-casing': ['error']}">

```vue
<template>
  <!-- ✓ GOOD -->
  <slot name="foo" />
  <slot name="fooBar" />

  <!-- ✗ BAD -->
  <slot name="foo-bar" />
  <slot name="foo_bar" />
  <slot name="foo:bar" />
</template>
```

</eslint-code-block>

## :wrench: Options

```json
{
  "vue/slot-name-casing": ["error", "camelCase" | "kebab-case" | "singleword"]
}
```

- `"camelCase"` (default) ... Enforce slot name to be in camel case.
- `"kebab-case"` ... Enforce slot name to be in kebab case.
- `"singleword"` ... Enforce slot name to be a single word.
