TypeScript + Snippet: Error about using uninitialized variable

[webJose]

Describe the bug

I started the investigation on this because of a different problem with TypeScript in one of my projects at work. While trying to reproduce the error "Cannot find name 'snippet name'. (ts2304)", I stumbled upon this one:

Reproduction

1. npm create vite@latest
2. npm i
3. Add src/lib/Test.svelte.
4. Add the below content to the new file.

<script lang="ts" module>
    export const reusable = _reusable;
</script>

{#snippet _reusable(x: number)}
    <div>{x}</div>
{/snippet}

I am guessing that, while the error is there, the export works fine, as it works fine in my work project with the arguably worse "Cannot find name" error.

Logs

No response

System Info

You can do this instead (see documentation):

<script lang="ts" module>
    export { reusable };
</script>

{#snippet reusable(x: number)}
    <div>{x}</div>
{/snippet}

Or this, if you need to rename the export:

<script lang="ts" module>
    export { reusable_ as reusable };
</script>

{#snippet reusable_(x: number)}
    <div>{x}</div>
{/snippet}
