Steps to reproduce

defineEmits stopped typing after updating to typescript v5.5.2

I think just create component with defineEmits and you must see an issue.

Link to minimal reproduction

No response

Any additional comments?

Interesting that inside VSCode defineEmits are shown by Vue Official (version v2.1.0-insiders.13) 🤔

Component is shadcn-vue PinInput

Error only received after vue-tsc --noEmit script running on simple-git-hooks pre-commit

When making reproduction everything works fine with simple components, maybe issue inside Radix library, I don't know 🫠

Confirmed, there is an issue with vue-tsc when upgrading to typescript@5.5.2. Same happens when you install 5.5.2 and use the workspace's typescript version rather than the one from vscode:

Issues

• Typedefs of certain components won't be written (haven't figured out the underlying reason yet)
• Syntax highlight is broken (imported components are marked as unrecognized)

Steps to reproduce

• pnpm create vite@latest
• pnpm update
• Point TS version to workspace
• Create files and restart LSP:

App.vue

<template>
    <HelloWorld msg="asdf" />
</template>

<script setup lang="ts">
import HelloWorld from './HelloWorld.vue'
</script>

HelloWorld.vue

<script setup lang="ts" >
defineProps<{ msg: string }>()
</script>

<template>
  <div></div>
</template>

Workaround

Make sure to pin your typescript dependency to ~5.4.0 and to use the typescript version shipped with vscode.

UPD: yeah, when change VS Code version of typescript to workspace v5.5.2, error shows in editor too

Maybe this is somehow related to: microsoft/TypeScript#58960

True, please pin typescript to v5.4 for now
