[Bug]: 'type' declaration inside package.json is missing, causing it to be considered a CommonJS module

[greybaron]

Expected Behavior

Importing the module works as it does in StackBlitz SvelteKit example

Current Behavior

After importing the dependency, multiple errors are thrown about cookieconsent being a CommonJS module:

SyntaxError: [vite] Named export 'run' not found. The requested module 'vanilla-cookieconsent' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'vanilla-cookieconsent';
const {run} = pkg;

[multiple similar errors...]

the workarounds provided by the error messages are ineffective.

Steps to reproduce

Generate a new SvelteKit 2.x project, using Node 20.x
Recreate the StackBlitz example

Proposed fix or additional info.

Since this is an ES module, the following property should be set inside package.json:
"type": "module",
Without this property, Node considers this to be a CommonJS module and throws multiple errors.

Note: I assume this behaviour was introduced between Node 18.18 and 20.x, as it works on Node 18 on StackBlitz

Version

3.0.0

On which browser do you see the issue?

I can confirm the issue.

Although the #661 does fix this setup, it also breaks the test suite, as jest (the test framework) doesn't support es modules.

The workaround, for now, is to use the import * syntax:

import * as CookieConsent from 'vanilla-cookieconsent';
