Error when importing createNamespacedHelpers

[samuveth]

I'm trying to use this package with my vue-3 app and the composition api, but I'm running into this error. Any ideas?

Version: "vuex-composition-helpers": "^2.0.0",

import { createNamespacedHelpers } from 'vuex-composition-helpers';
const { useState } = createNamespacedHelpers('favoriteSpaces');

export default {
  setup() {
    const { favorites } = useState(['favorites']);
 }
}

 error in ./node_modules/vuex-composition-helpers/dist/util.js

Module parse failed: Unexpected token (52:20)

You should install "vuex-composition-helpers@next" with vue3.
There are several differences that needed a major update for the package.

[samuveth]

@davidmeirlevy I did that, I'm on ^2.0.0

Any updates?

It seems like your code is failing due to the usage of optional chaining.
as you can see, your error is:
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

and it's regarding the line: return vm.proxy?.$store;

you probably need node 14+, and to accept optional chaining.

As mentioned on babl, it's already included in the latest version of @babel/preset-env when using ES2020:
https://babeljs.io/docs/en/babel-plugin-proposal-optional-chaining

Its common practice for people to exclude node_modules from being processed by babel because running all your dependencies through a transpiler makes your builds much longer. Could you update your compile target to not include features like this?

How was this resolved guys?
