 | 14 | +## :book: Rule Details  | 
 | 15 | + | 
 | 16 | +This rule enforces a consistent style for handling Vue 3 Composition API props, allowing you to choose between requiring destructuring or prohibiting it.  | 
 | 17 | + | 
 | 18 | +By default, the rule requires you to use destructuring syntax when using `defineProps` instead of storing props in a variable and warns against combining `withDefaults` with destructuring.  | 
 | 19 | + | 
 | 20 | +<eslint-code-block :rules="{'vue/define-props-destructuring': ['error']}">  | 
 | 21 | + | 
 | 22 | +```vue  | 
 | 23 | +<script setup>  | 
 | 24 | +  // ✓ GOOD  | 
 | 25 | +  const { foo } = defineProps(['foo'])  | 
 | 26 | +  const { bar = 'default' } = defineProps(['bar'])  | 
 | 27 | +
  | 
 | 28 | +  // ✗ BAD  | 
 | 29 | +  const props = defineProps(['foo'])  | 
 | 30 | +  const propsWithDefaults = withDefaults(defineProps(['foo']), { foo: 'default' })  | 
 | 31 | +
  | 
 | 32 | +  // ✗ BAD  | 
 | 33 | +  const { baz } = withDefaults(defineProps(['baz']), { baz: 'default' })  | 
 | 34 | +</script>  | 
 | 35 | +```  | 
 | 36 | + | 
 | 37 | +</eslint-code-block>  | 
 | 38 | + | 
 | 39 | +The rule applies to both JavaScript and TypeScript props:  | 
 | 40 | + | 
 | 41 | +<eslint-code-block :rules="{'vue/define-props-destructuring': ['error']}">  | 
 | 42 | + | 
 | 43 | +```vue  | 
 | 44 | +<script setup lang="ts">  | 
 | 45 | +  // ✓ GOOD  | 
 | 46 | +  const { foo } = defineProps<{ foo?: string }>()  | 
 | 47 | +  const { bar = 'default' } = defineProps<{ bar?: string }>()  | 
 | 48 | +
  | 
 | 49 | +  // ✗ BAD  | 
 | 50 | +  const props = defineProps<{ foo?: string }>()  | 
 | 51 | +  const propsWithDefaults = withDefaults(defineProps<{ foo?: string }>(), { foo: 'default' })  | 
 | 52 | +</script>  | 
 | 53 | +```  | 
 | 54 | + | 
 | 55 | +</eslint-code-block>  | 
 | 56 | + | 
 | 57 | +## :wrench: Options  | 
 | 58 | + | 
 | 59 | +```js  | 
 | 60 | +{  | 
 | 61 | +  "vue/define-props-destructuring": ["error", {  | 
 | 62 | +    "destructure": "always" | "never"  | 
 | 63 | +  }]  | 
 | 64 | +}  | 
 | 65 | +```  | 
 | 66 | + | 
 | 67 | +- `destructure` - Sets the destructuring preference for props  | 
 | 68 | +  - `"always"` (default) - Requires destructuring when using `defineProps` and warns against using `withDefaults` with destructuring  | 
 | 69 | +  - `"never"` - Requires using a variable to store props and prohibits destructuring  | 
 | 70 | + | 
 | 71 | +### `"destructure": "never"`  | 
 | 72 | + | 
 | 73 | +<eslint-code-block :rules="{'vue/define-props-destructuring': ['error', { destructure: 'never' }]}">  |
