Reproduction

Describe the bug

The defineEventHandler() function used in the ~/server/api folder is marked as undefined.

Error message: Cannot find name 'defineEventHandler'.(2304) any

Additional context

As stated in the documentation,

Nuxt exposes every auto-import with the #imports alias that can be used to make the import explicit if needed

import { defineEventHandler } from '#import'; returns an error too: Cannot find module '#import' or its corresponding type declarations.

Logs

No response

managed to get it working by adding h3 as a dependency and calling it explicitly:

in server/api/middleware/log.js

import { defineEventHandler } from 'h3';

export default defineEventHandler((ev) => console.log(ev.req.url));

I believe this is caused by the fact that stackblitz hides the .nuxt folder. Let’s see what the team there might be able to do.
