Path aliasing doesn't work in +config.ts files

[w7it]

Description

I'm trying to use absolute import with path aliasing that I successfully enabled (it works properly in regular components):

import type { Config } from 'vike/types';
import { SITE_NAME } from '~/constants.js';

export default {
    title: SITE_NAME
} satisfies Config;

But it doesn't work in +config file:

> vite build

error during build:

As a workaround I've switched to relative imports, but itsnot convenient honestly :)

Define your path aliases at package.json#imports as described in https://vike.dev/path-aliases.

Also see #1547.

@brillout thanks, but it doesn't work :(

I've added imports like this:

  "imports": {
    "#*": "./src/*"
  },

and change my import to this:

import { SITE_NAME } from '#constants.js';

VScode resolves it perfectly, BUT vike doesn't:

if I change extension to .mjs vike works well! BUT VScode doesn't ¯\_(ツ)_/¯

import { SITE_NAME } from '#constants.mjs';

maybe you know how to fix it? I've found only one solution: rename constants.ts to constants.mjs and enable allowJs in typescript

Can you create a minimal reproduction?
