This will be fine.

Example

<script lang="ts">

</script>

<script setup lang="ts">
interface Props {
  // zoom?
  a?: string;
}
const props = withDefaults(defineProps<Props>(), {
  a: "a",
});
</script>

this has nothing to do with zoom thing.

@liulinboyi
But Volar (VSCode extension) complains about the Props

Moving the interface is recommended by Volar creator:

You're right, it doesn't on the playground. However on my local it does

I noticed this bug too, is the PR submitted by @edison1105 ready to be merged? I see that all checks passed, is it waiting for a specific approval?

Fixed by naming prop primary something else

[alperkay]

This problem still seems to exist. Any news on how to solve this?

[azamat-sharapov]

This is a documented feature and not working. I wonder why the fix still not merged, it has been 8 months..

Fixed by naming prop primary something else

Can you give more details? const primary = defineProps<Props>() didn't help. Also tried const primarySomething = ....

@azamat-sharapov I think I meant prop itself, not the variable. I think it should be called const props = defineProps<Props>()
