'builder:watch' hook isn't released when nuxt.config is updated

[danielroe]

I noticed that the 'builder:watch' hook won't be release after the nuxt.config is updated. As the dev server is restarted, this hook will be registered multiple times.

I don't know if this behavior is expected, but it never happened when I was developing modules three months ago. There may be some similarities between these issues.

Would you be able to provide a 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?

We have a couple of templates for starting with a minimal reproduction:

👉 https://stackblitz.com/github/nuxt/starter/tree/v3-stackblitz
👉 https://codesandbox.io/s/github/nuxt/starter/v3-codesandbox

A public GitHub repository is also perfect. 👌

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