Hi. `svelte2tsx` maintainer here. `svelte2tsx` uses TypeScript API to parse script tag content so I don't think it'll work if you don't have TypeScript. Also, we don't recommend using AST...

To type the prop you need to type the props object and not individual props. https://svelte-5-preview.vercel.app/docs/runes#$props The `unknown` part is generated by language-tools. But without that, it will still be...

The problem is that this is treated as implicit props so no virtual variable is generated for the snippet. Instead, it's directly passed to SomeCommponent as props. So yes. making...

Behind the scenes, a virtual ts is generated so TypeScript can understand the svelte file. What I meant is that because it is an implicit prop. The generated snippet is...

Note for self, one advantage of inlining the snippet as Component props is that the type is inferred. If we always transform this as a variable the parameter type won't...
