Can't resolve module/server/api from package in monorepo

[kzotov]

Environment

Operating System: Darwin
Node Version: v18.13.0
Nuxt Version: 3.4.2 (But same with 3.5.1)
Nitro Version: 2.3.3
Package Manager: pnpm@8.4.0

Reproduction

I have a monorepo with custom modules and some packages

modules
|-custom-module-name
   |-src
     |-runtime
       |-server
         |-api
           |-healthcheck.get.ts
packages
|-package-name

At the packages i've using custom module, which contains module/custom-module-name/server/api/healthcheck.get.ts file.

Module setup file modules/custom-module-name/src/module.ts:

import { addServerHandler, defineNuxtModule } from '@nuxt/kit';

export interface ModuleOptions {}

export default defineNuxtModule<ModuleOptions>({
  setup(options, nuxt) {
    addServerHandler({
      route: '/api/healthcheck',
      handler: resolve(runtimeDir, 'server/api/healthcheck.get.ts'),
    });
  },
});

healthcheck.get.ts:

const startTime = new Date();

export default defineEventHandler(() => {
  return {
    status: 'success',
    uptime: process.uptime(),
    upSince: startTime,
    localTime: new Date(),
    env: {
      nodeEnv: process.env.NODE_ENV,
      pid: process.pid,
    },
  };
});

Describe the bug

It works fine at dev environment: http://localhost:3000/api/healthcheck

But when it builds, there is warnings:

"[path]/modules/custom-module-name/dist/runtime/server/api/healthcheck.get.ts" is imported by "virtual:#internal/nitro/virtual/server-handlers", but could not be resolved – treating it as an external dependency.

Additional context

You should not add the .ts extension as this will not be present when you build your module.

[kzotov]

It works fine. Thank you.

This caught me out too, since its that way in the documentation.

@danielroe Must be reopen or addressed somewhere else, as mentioned before, the docs are missleading in this regard.
