Reproduction

Public github repo:

https://github.com/juanpscotto/nuxt-4-module-starter-types-issue

Stackblitz:

https://stackblitz.com/github/juanpscotto/nuxt-4-module-starter-types-issue?file=src%2Fruntime%2Fcomponents%2FNavigationComponent.vue%3AL29

In stackblitz wait until the project is setup. Or run this command npm run dev:prepare && npm run prepack if running locally.

Once it has finished check the dist/runtime/components/NavigationComponent.d.vue.ts file, the slot type is missing.

Additional context

There is one component NavigationComponent that has a named slot content with a data prop array of type NavigationItem[]. That type is carried over as any in both NavigationComponent.d.vue.ts and NavigationComponent.vue.d.ts files

NavigationComponent.vue:

NavigationComponent.d.vue.ts

Describe the bug

The slot props types are not being carried over to the generated .ts files of the .vue components. I expect the type of the data props to be recognized.

Would you be able to provide a minimal reproduction? 🙏

More info

Why do I need to provide a reproduction?

Reproductions make it possible for us to triage and fix issues quickly with a relatively small team. It helps us discover the source of the problem, and also can reveal assumptions you or we might be making.

What will happen?

If you've provided a reproduction, we'll remove the label and try to reproduce the issue. If we can, we'll mark it as a bug and prioritize it based on its severity and how many people we think it might affect.

If needs reproduction labeled issues don't receive any substantial activity (e.g., new comments featuring a reproduction link), we'll close them. That's not because we don't care! At any point, feel free to comment with a reproduction and we'll reopen it.

How can I create a reproduction?

Please use a template below to create a minimal reproduction

A public GitHub repository is also perfect. 👌

Please ensure that the reproduction is as minimal as possible. See more details in our guide.
