Vue Prop Konverter

Convert Vue defineProps() object-style definitions into type-safe, destructured TypeScript automatically in VS Code.

---

[!WARNING]
This extension is currently in beta. Some features may not work perfectly. For example:

• Callback props may not be correctly inferred
• Extremely dynamic or computed prop definitions
• Certain nested default values or unusual object syntax
  Please report any issues on the GitHub repository.

Features

• Converts object-style defineProps to TypeScript generic + destructuring syntax
• Automatically replaces props.propName usages with destructured variables
• Supports:
  • Default values
  • Required props
  • PropType<T> for arrays, objects, or custom types
• Works only in typescript blocks (<script lang="ts">)
• QuickFix via the VS Code lightbulbundefined

Demo

undefinedBefore:undefined

const props = defineProps({
  title: {
    type: String,
    default: 'Untitled',
  },
  isPublished: {
    type: Boolean,
    required: true,
  },
  tags: {
    type: Array as PropType<string[]>,
    default: () => ['vue', 'typescript'],
  },
  metadata: {
    type: Object as PropType<{ author: string; date: string }>,
    default: () => ({ author: 'Unknown', date: new Date().toISOString() }),
  },
  maxItems: {
    type: Number,
    default: 10,
  },
  callback: {
    type: Function as PropType<() => void>,
  },
})

undefinedAfter conversion:undefined

const {
  title = 'Untitled',
  isPublished,
  tags = (['vue', 'typescript']),
  metadata = ({ author: 'Unknown', date: new Date().toISOString() }),
  maxItems = 10,
} = defineProps<{
  title?: string
  isPublished: boolean
  tags?: string[]
  metadata?: { author: string; date: string }
  maxItems?: number
}>()
